kadovar volcano eruption

According to the Darwin VAAC, a pilot reported an ash plume at 3.9 km altitude drifting SE on 2 March; it was not visible in satellite imagery due to meteoric clouds. Clicking on the small images will load the full 300 dpi map. The NOAA/CIMSS Volcanic Cloud Monitoring system generated an alert for the ash cloud moving WNW, as imaged by S-NPP VIIRS at 0330 UTC on 5 January; Himawari-8 imagery subsequently showed that the eruption began around 0220 UTC. On 14 September, photographs were taken during an aerial inspection. Previously (1976-77) sea discolouration was present at the S shore and was related to the development of a new thermal area on the S flank of the island. Strong sulfur dioxide emissions were detected. | October and drifted SE and E. On 2 December ash plumes rose to 1.2 km (4,000 ft) a.s.l. A few volcano-seismic events were recorded in both November and December, but such events appeared to be absent in February. Reports are organized chronologically and indexed below by Month/Year (Publication Volume:Number), and include a one-line summary. According to the Darwin VAAC, ash plumes from Kadovar were visible in satellite images on 21 October drifting NE at an altitude of 2.4 km (8,000 ft) a.s.l. Continuous ash emissions rising to 1.8 km altitude were reported by the Darwin VAAC beginning on 9 November 2018 moving WNW and lasting about 24 hours. A dome appeared at the base of the E flank during March-May 2018 (Planka et al., 2019); by November activity had migrated to a new dome growing near the summit on the E flank. Vertical aerial photographs were taken by a survey firm on 15 November, and aerial obliques were taken during the December inspection. Eruptive activity through 2018 changed the morphology of the SE side of the island and activity continued through 2019 (figure 36). A brief emission to 3.7 km was also noted that day. Kadovar is also a Holocene stratovolcano with a suspected (but not confirmed) eruption in 1700. Mount Kadovar, which is located about 18 miles off the north coast of Papua New Guinea near the mouth of the Sepik River, started erupting on Friday. The ash plume was not identified in satellite data. | June ", Few changes in the main thermal area; no volcano-seismic activity. The waves were reported at 1050, before the main collapse of the dome. More than 500 people were evacuated as a result. Based on satellite data, the Darwin VAAC reported that on 2 February an ash plume from Kadovar rose to an altitude of 1.5 km (5,000 ft) a.s.l. Sources: Rabaul Volcano Observatory (RVO); Loop; Darwin Volcanic Ash Advisory Centre (VAAC); NOAA Cooperative Institute for Meteorological Satellite Studies. Kadovar volcano map: Where is the erupting volcano in Papua New Guinea? Activity during January-June 2020. The main fumarole area had enlarged again and was estimated at about 150 x 70 m, and the area of dead vegetation was more prominent. Thick lava flows with columnar jointing forms low cliffs along the coast. Five newly-named vents were observed during an overflight conducted on 13 January: Main Crater, Western vent, and Southern vent (all three are at the summit), the SE Coastal vent, and the Southern Coastal vent. The first confirmed historical eruption at Kadovar began around mid-day local time on 5 January 2018, according to witnesses. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. and drifted SW. Based on satellite and wind model data, the Darwin VAAC reported that on 18 November ash plumes from Kadovar rose to an altitude of 0.9 km (3,000 ft) a.s.l. The Kadovar Island volcano, which is approximately 24 kilometers north of the Papuan mainland, began erupting on January 5. The waves were reported at 1050, before the main collapse of the dome. Based on satellite and wind model data, the Darwin VAAC reported that on 3 January two ash puffs from Kadovar rose to an altitude of 1.5 km (5,000 ft) a.s.l. By Amani Hughes. Continuous steam emissions from both the Main Crater and the SE Coastal Vent were interrupted by dark ash plumes on 16 and 20-22 February, and occasional explosions were heard by residents on nearby islands. Some noise was heard on Ruprup Island emanating from Kadovar in the early hours of Monday morning. An elongate area extending from the summit area to the E-flank coastal dome appears lighter in color in a 7 September Sentinel-2 natural color satellite image, and as a higher temperature area in the correlating thermal bands, indicating a hot avalanche deposit. and drifted WSW and W. The Darwin VAAC reported that discrete, low-level events at Kadovar regularly occurred on 14 November based on satellite data. Intermittent ash plumes, pulsating gas and steam plumes, and thermal anomalies continued at Kadovar during January-June 2020. the S coast, which may have been a small hydrothermal eruption or, more likely, a vigorous ebullition of gas bubbles. The Darwin VAAC reported that during 29-30 October intermittent ash plumes from Kadovar rose to altitudes of 1.8-2.1 km (6,000-7,000 ft) a.s.l. The first signs were noted May 1976 from an area at the S coast where possibly a small hydrothermal eruption or, more likely, a vigorous emission of gas bubbles occurred. During January, small SO2 plumes were recorded by NASA satellites on four occasions (figure 17). Activity in early 2019 included regular gas and steam emissions, ash plumes, and thermal anomalies at the summit (BGVN 44:05). The thermal anomaly at the summit persisted in satellite imagery taken on 15 April 2019. Volcanic plumes were sometimes observable in Wewak (105 km W). Kadovar Volcano Volcanic Ash Advisory: DISCRETE VA ERUPTION TO FL060 MOV N OBS AT 08/0620Z to 6000 ft (1800 m) Wednesday, Oct 07, 2020 Kadovar Volcano Volcanic Ash Advisory: DISCRETE VA ERUPTION TO FL060 MOV NW OBS AT 07/2130Z to 6000 ft (1800 m) 2018: January RVO reported that the eruption at Kadovar continued during 18-19 and 21-22 January. RVO issued an information bulletin on 7 February reporting that, since the beginning of January, the eruption had continued with frequent Vulcanian explosions from the Main Vent with a recurrence interval of hours to days. | October Aerial photos and observations from Samaritan Air flights showed dark gray ash and steam plumes rising from a crater on the SE side of the summit. The Kadovar Island volcano, which is approximately 24 kilometers north of the Papuan mainland, began erupting on January 5. Ash plumes rose 370 m above the island and drifted SE, though on 22 February the winds blew the plumes N and NW. Kadovar is an island volcano north of Papua New Guinea and northwest of Manam. Incandescence from both areas was visible on 22 February. According to the Darwin VAAC a pilot observed an ash plume from Kadovar on 2 March drifting SE at an altitude of 4 km (13,000 ft) a.s.l. A seismic event counter was installed on the island. The maps shown below have been scanned from the GVP map archives and include the volcano on this page. MODVOLC thermal alerts were issued on three days; 15 and 22 January, and 7 February 2018. J. Volcanol. Satellite data. The remote Kadovar Island volcano became active on 5 January 2018 with mild volcanic activity on the south-eastern side of the island. During their return trip from Bam on 8 January 2018, the missionaries again circled the island and noted that the eruption seemed to be occurring from different vents. Based on satellite and wind model data, the Darwin VAAC reported that on 16 August an ash plume from Kadovar rose to an altitude of 1.5 km (5,000 ft) a.s.l. Ash emissions were generally continuous at altitudes from 2.4 to 3 km, although low level emissions of primarily steam and gas were observed on 20 January that included intermittent phases of increased ash content. Additional imagery on 10 and 30 January showed a single anomaly at the summit, even through dense meteorologic clouds. The volcano, on Kadovar Island northeast of Papua New Guinea, lay dormant until January 5 when it began to erupt at around noon, local media reports.

Problems of volcanic hazards in Papua New Guinea. Gas emissions also continued and a Volcano Observatory Notice for Aviation (VONA) was issued on the 19th reporting an ash plume to an altitude of 1.5 km and drifting NW. The main part of the dome had bulged up, and a valley developed in between the dome and the island’s flank. The Southern Coastal Vent, located where the original fractures entered the sea, was inactive. Lowenstein P L, 1982. Our expert volcanologists and photographers offer unique travel experiences: Just 9 minutes ago, a 4.5-magnitude earthquake struck near Calingasta, Departamento de Calingasta, San Juan, Argentina. First confirmed historical eruption, ash plumes, and lava flow, January-March 2018. Unusually high seismic event counts on Kadovar are suspect because of a malfunctioning event counter. According to Brad Scott of GeoNet, the Royal New Zealand Air Force released photos of a plume rising from Kadovar at 1640 on 10 February. ", No significant changes in the thermal area. The growth rate slowed later in the month, and only one meter of change was observed between 10 and 20 March. Geol Surv Papua New Guinea Rpt, 82/7: 1-62. An ash plume was imaged on 17 July by Landsat 8 with a gas-and-ash plume dispersing to the west (figure 39). Two thermal anomalies were visible at the summit in satellite imagery on 26 November, they grew larger and more intense through 16 December when multiple anomalies appeared at the summit and on the E flank (figure 31). An investigation [on 3 August] was made by Rabaul Volcano Observatory (RVO) volcanologists D. Wallace and R. Almond. Light gray steam and ash rose from near the summit and drifted NW covering the N half of the island in ash; a large eruption of dark gray ash shot upward from a different vent on the SE flank surrounded by … By Alice Foster. We welcome users to tell us if they see incorrect information or other problems with the maps; please use the Contact GVP link at the bottom of the page to send us email. and drifted W and NW. The island is approximately 1.4 km in diameter with very steep slopes, located about 25 km NNE from the mouth of the Sepik River on the New Guinea mainland. Schichtvulkan 365 m / 1,197 ft Northeast of New Guinea, Papua Neuguinea, -3.63°S / 144.63°E Aktueller Status: Schwache Aktivität oder Ausbruchswarnung (3 von 5) Kadovar Webcams / aktuelle Daten | Reports Kadovar Vulkan-Bücher ... An earthquake of magnitude 4.2 occurred only 13 minutes ago 79 km northeast of Sorong, Indonesia, Indonesia's Meteorology, Climatology, and Geophysical Agency (BMKG) reported. Shiveluch volcano, Russia The main body of the flow significantly bulged upwards, with a distinct 'valley' visible between the bulge and the island's flank. Res., 186: 210-222. Residents on Blup Blup (15 km N) could see incandescence high on the volcano's flank. THE REMOTE island volcano of Kadovar is erupting and sending huge plumes of ash into the sky just off the coast of Papua New Guinea. Dent; 30 September, C.O. Intermittent puffs of steam rose from both the summit and the coastal dome in mid-June; the summit plume was much denser on 29 July (figure 22). Visitor observations on 21 October 2019. Main Crater produced ash plumes that rose as high as 800 m above the summit and drifted tens of kilometers E, SE, S, and SW. Vulcanian activity was continuous, though no discrete explosions were detected. A possible eruption was witnessed by explorers in 1700; no other activity was reported until an outbreak of thermal activity in 1976 (NSEB 01:14-01:11, SEAN 03:09) and a short period of seismic unrest in 2015, according to RVO. During the period if increased activity dense dark gray and brown ash plumes rose several hundred meters above the summit crater (700-800 m) and drifted NW. The SE Coastal Vent was very active with dense white steam emissions rising 600 m from the vent (figure 15). Although initial news reports regarding the population and evacuation status were unclear, the East Sepik Governor, Allan Bird, told media on 8 January that 591 residents of Kadovar had been evacuated to Blup Blup island (about 10 km N) due to the organizational efforts of village councilors on the two islands. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. October 1976. "Although the initiation and early rapid development of this thermal activity led to the belief in a forthcoming Kadovar eruption, the stabilization (or even slight decline) in activity suggests the possibility that the event may be confined to thermal activity. A sulfur odor was noticed by residents on Blup Blup (15 km N) on 16 and 22 February. Sources: Rabaul Volcano Observatory (RVO); Darwin Volcanic Ash Advisory Centre (VAAC). Information Contacts: Acting Senior Volcanologist, RVO. Persistent steam and intermittent ash plumes were produced from the summit vent through the end of March. Such purely thermal events have been reported elsewhere. Observers on Blup Blup saw incandescence emanating from either the summit or an area out of view on the S flank. Also on 6 January 2018, missionary Brandon Buser set out from Wewak to visit Bam by boat. Its rim drops steeply into the sea. The volcano on Kadovar island began emitting smoke and ash last week, prompting the evacuation of more than 500 people to nearby Blup Blup island. Main Crater produced light-gray to brown ash plumes that rose at most 100 m and drifted a few tens of kilometers W. Weak incandescence from Main Crater was visible at night. Since then no eruptions are known, and no traces of thermal activity remained in early 1976, although there was supposedly some such activity several generations ago. Minor ashfall was reported on Blup Blup on 21 and 22 February. The Rabaul Volcanological Observatory in Papua New Guinea says the eruption of Kadovar Island remains dynamic. The Australian government is contributing 25,000 Australian dollars (nearly $20,000) in humanitarian supplies to Papua New Guinea, Australian foreign minister Julie Bishop wrote in a tweet. An investigation [during 10-12 November] was made by volcanologist V. Dent, physicist D. Norris (University of Papua New Guinea, Port Moresby), and D. Mahar. (the water depth in that area was unknown) and extends out from the coast 150-200 m. The dome glowed red at night. The events included the collapse of a lava dome on 9 February 2018. In early August 1976, the first reports were received of activity there, the precise nature of which has not been clearly established. Based on satellite and wind model data, the Darwin VAAC reported that during 5-7 January ash plumes from Kadovar rose to altitudes of 1.5-1.8 km (5,000-6,000 ft) a.s.l. ,#EruptionsOfinstagram #KadovarVolcanoEruption #KadovarVolcano #Eruption #Kadovarisland #BismarckSea #PapuaNewGuinea #Volcanoes Kadovar Volcano (Northeast of New Guinea ): explosive eruption … The crater rim was covered with dead vegetation, ash, and large bombs from recent explosions (figure 53). A brief ash emission was reported on 21 October 2018 at 2.4 km altitude drifting NE for a few hours. Dark gray ash plumes rose from the dome. Color code explanation (click to close legend) Black = (Probably) extinct Green = normal activity / dormant Yellow = unrest: some signs of unrest, but no eruption in near future ( "An area of orange discolouration of the sea at the NE shore was observed during aerial inspections on 6 and 19 March. and drifted NW. By 7 January, the plume could be identified about 220 km WNW in satellite images (figure 13). Reference: Planka S, Walter T R, Martinis S, Cescab S, 2019, Growth and collapse of a littoral lava dome during the 2018/19 eruption of Kadovar Volcano, … | February On 1 October an ash plume rose to 2.7 km and drifted W. Infrared satellite data from Sentinel-2 showed hot spots in the summit crater and at the Coastal Vent along the W shoreline on 10, 15, and 25 April 2018; plumes of brown discolored water were streaming from the western side of the island (figure 18). RVO reported a significant escalation in activity during 12-13 January 2018. At 1830 local time on 1 February, a collapse of the side of the flow facing Blup Blup was observed; it resulted in a plume of gray ash and then vigorous steaming at the collapse site, which also was incandescent at night. Its first confirmed observed eruption began in early January 2018, with ash plumes and lava extrusion resulting in the evacuation of around 600 residents from the N side of the island (BGVN 43:03). The maps database originated over 30 years ago, but was only recently updated and connected to our main database. By the end of the first week of March 2018 the flow was about 17 m above sea level; its growth rate had slowed, adding only one meter by late March. The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. This report covers activity from the beginning of the eruption on 5 January through March 2018. At 1830 on 1 February a collapse of the N part of the dome produced a gray plume, vigorous steaming at the collapse site, and nighttime incandescence. Uru in Yangoru (130 km W), Woginara (140 km W), and the Wewak District (100 km W). The Royal New Zealand Air Force released images of eruptive activity on 10 February 2019 (figure 33). After local reports of the eruption Samaritan Airlines flew administrators from the Wewak district to investigate, enabling photographs of ash and steam emissions (figure 2). The ash plume was not identified in satellite data. Kadovar volcano is an island located 25km north of the entrance to the Sepik River, Papua New Guinea. But will the volcano erupt again? No measured temperatures exceeded 100°C, although the upper part of the main zone has become hotter, approaching 100°C. The only features presently indicating continued development are weak thermal areas that are still being established in new areas on other parts of the island. Most of the village gardens are on the side of the dome. McKee; 13-14 November, C.O.

The youthful island lacks fringing or offshore reefs. Strong sulfur dioxide emissions were detected. In a 12 February report, RVO noted that activity from Main Crater consisted of white plumes rising 20 m and drifting a few kilometers SE accompanied by weak nighttime crater incandescence. The islanders were displaced after the Kadovar volcano erupted in 2018. | August There was some heightened thermal phenomena in … It is part of the Schouten Islands, and lies off the coast of New Guinea, about 25 km N of the mouth of the Sepik River. 2020: January Multiple thermal anomalies were still visible at the summit in satellite imagery on 5 January 2019 as regular puffs of steam drifted SE from the summit, leaving a long trail in the atmosphere (figure 32). Ashfall was reported on Kairiru and Mushu islands (115 km WNW), Mt. However, the event will continue to be treated as a possible precursor to an eruption, and the former inhabitants will be advised to maintain the evacuation for the present. Low-level ash emissions were reported briefly on 28 November at about 1 km altitude moving SE. Shortly before arriving on the island an ash plume rose tens of meters above the summit and drifted W (figure 51). If the magma is more viscous, essentially less fluid, the gas bubbles inside the magma will have a hard time escaping to the surface, and so will cause the volcanic material to rise up, causing a bigger, more violent eruption. But will the volcano erupt again? Steam plumes from the SE Coastal Vent rose 800 m above the island, and a lava dome which strongly and continuously glowed at night slowly extruded from the vent. and drifted SE. The island has the form of a steep-sided cone 250 m high, with a 600-m-wide crater breached to the SSE. | November. Volcano Discoveries : "One of the most eye-catching guides to the world’s volcanoes ever published." Satellite imagery on 1 March 2019 confirmed a strong thermal anomaly from the summit and down the E flank almost to the coast. RVO reported that the eruption at Kadovar continued during 31 January-1 February at a low level. Ash plumes drifted tens of kilometers W and NW. The SE Coastal Vent was very active, emitting dense white steam plumes 600 m a.s.l. Authorities in Papua New Guinea have warned people living near the Kadovar Island volcano to prepare for the worst, with fears an eruption there could trigger a tsunami. A possible lava dome was at the base of the plumes but showed no evidence of incandescence. The first confirmed historical eruption at Kadovar began around mid-day local time on 5 January, according to witnesses. The growing dome produced periodic pulses of dense steam during his visit (figure 55). 2021: January Based on satellite data, the Darwin VAAC reported that on 18 October a discrete ash puff from Kadovar rose to an altitude of 1.5 km (5,000 ft) a.s.l. Thermal anomalies and emissions continued through to the end of 2019 (figure 41). This thermal area was now observed to have been reduced in size by regrowth of vegetation.". Kadovar is a 365-m-high, 1.4 km-diameter volcanic island. | November Report on Bam Island volcano and an inspection of Kadovar and Blup Blup. From the NW side of the summit crater rim, Jung saw the actively growing dome on the side of a larger dome, and steam and gas issuing from the growing dome (figure 52). RVO reported that the eruption at Kadovar continued during 1 January-7 February with frequent (hours to days) Vulcanian explosions from Main Vent at the summit. and drifted ESE. and drifted NW. The erupting Kadovar Island Photo: East Sepik Provincial Government The tiny island off the north coast of PNG's mainland erupted earlier this month. Kadovar volcano map: Where is the erupting volcano in Papua New Guinea? and drifted NW and W. RVO reported quiet conditions at Kadovar during 1-20 September with only diffuse white plumes rising from the volcano. While the ash plume erupted near-vertically above the island, a more diffuse gas plume rose from multiple vents on the summit dome and dispersed at a lower altitude. Explosions at 1652 and 1815 generated dense dark gray ash plumes that rose 1 km and drifted W. Loud rumbling accompanied the explosion.
