Kadovar volcano stratovolcano 365 m / 1,197 ft Northeast of New Guinea, Papua New Guinea, -3.63°S / 144.63°E Current status: minor activity or eruption warning (3 out of 5) A higher plume drifted WNW at 2.4 km altitude on 7 October. During 18-22 January 2018, the Main Crater continued to produce moderate to dark gray ash plumes that rose 500-800 m above the summit, drifting locally S and SE, and a continuous steam plume from the SE Coastal Vent rose as high as 800 m above the island. and drifted ESE. The only known eruption occurred in January 2018. Dates and personnel were: 18-19 August, V.F. The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Explosions recorded at 2045 on 8 July, 1145 and 1400 on 9 July, and at 0950 and 1125 on 10 July produced ash plumes that rose 1 km above the summit. ", No significant changes in the thermal area. A lava flow on the E flank extended outward from the island, extruding from a vent low on the E flank and forming a dome just offshore. Kadovar volcano, PNG. All vegetation in the area had been killed. During April, pulsating steam plumes rose from two vents at the summit, and thermal anomalies appeared at both vents in satellite data (figure 48). Silver E, Day S, Ward S, Hoffmann G, Llanes P, Driscoll N, Appelgate B, Saunders S, 2009. It is sponsored by the, Information about large Quaternary eruptions (VEI >= 4) is cataloged in the, EarthChem develops and maintains databases, software, and services that support the preservation, discovery, access and analysis of geochemical data, and facilitate their integration with the broad array of other available earth science parameters. The Darwin VAAC reported the plume drifting WNW extending about 185 km on 8 January. The remote Kadovar Island volcano became active on 5 January 2018 with mild volcanic activity on the south-eastern side of the island. This compilation of synonyms and subsidiary features may not be comprehensive. Dormant volcano Kadovar wakes with first eruption in known history, spews lava . Kadovar could turn explosive, landslides and tsunamis possible, P.N.G. A dormant volcano that first began erupting on January 5 exploded on Friday, forcing the evacuation of hundreds of people from the Kadovar island in Papua New Guinea. Uru in Yangoru (130 km W), and Woginara (140 km W), along with locations along the W coast of the Wewak District. Minor ashfall was reported on Blup Blup on 21 and 22 February. MIROVA thermal data suggested persistent low-level anomalies throughout the period (figure 45). According to Brandon Buser, just after eruption plumes started rising from a vent on the SE side of Kadovar on 5 January boats from a village on the mainland (22 km SW) and from Bam (25 km E) were sent to the island to evacuate residents. 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) A satellite image from 21 March 2018 was one of the first showing the new dome growing off the E flank with a thermal anomaly and sediment plumes in the water drifting N and E from the area. Another aerial inspection was carried out on 7 January, the day after a shallow M 6.5 earthquake about 30 km WSW of Kadovar on 6 January, 0611 GMT (preliminary location by USGS). RVO estimated that the lava flow had risen to about 50 m above sea level and extended 150-200 m out from the coast. to 20000 ft (6100 m). Kadovar contains a 1 km wide breached crater, which is an avalanche amphitheatre. A newly formed small, weak patch of hot ground was found 100-200 m upslope of the main fumarole area. Following the first known eruption of Papua New Guinea's Kadovar volcano that took place on January 5, 2018, the Rabaul Volcanological Observatory (RVO) believes that the eruption could become explosive, posing a … MODVOLC thermal alerts were issued on three days; 15 and 22 January, and 7 February 2018. In a situational report issued by the observatory on Monday, eruption on Kadovar continues much the same as for the previous few days. Observers on Blup Blup saw incandescence emanating from either the summit or an area out of view on the S flank. November 1976. Large amounts of sulfur dioxide had been detected since 8 January, and continued to be emitted. RVO reported that activity significantly escalated on 12 January characterized by a large blast of a substantial amount of material and “big” glowing red rocks directed to the S; the report noted that the blast was the only one reported to date. Activity during October-December 2018. 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. The youthful island lacks fringing or offshore reefs. | February Continuous but dull glow emanated from the crater. The first confirmed eruption of Kadovar began on 5 January 2018 with dense ash plumes and steam and a lava flow. 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. Sulfur dioxide emissions and seismicity had both decreased. Space Shuttle photo STS027-0032-0071 looking southwest along the coast of Papua New Guinea and across the offshore volcanic islands. Kadovar is also a Holocene stratovolcano with a suspected (but not confirmed) eruption in 1700. The first confirmed historical activity began in January 2018 and resulted in the evacuation of residents from the island. As they were circling the island a large event sent a large plume hundreds of feet into the air and ejected large boulders into the ocean. 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. It is interesting to speculate that the 6 January earthquake may have been connected with the levelling-off of activity. Ground observers noted incandescence visible from both the summit and the E-flank coastal dome. 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. The explosions ejected rocks and ash plumes that rose 300-400 m above the vent and drifted NE and E. Residents on Blup Blup (15 km N) reported rumbling and nighttime summit incandescence. Government officers R. Allen and D. Mahar from Wewak inspected the fumarole area [on 14 October], which had intensified in activity and was about 150 x 50 m in area. This prompted authorities to evacuate the 590 occupants of the island. Satellite imagery on 1 March 2019 confirmed a strong thermal anomaly from the summit and down the E flank almost to the coast. and drifted SE. According to the International Federation of Red Cross and Red Crescent Societies (IFRC), the entire population of Kadovar, about 600 people who lived on the N side of the island, was relocated to nearby Blup Blup Island which is home to about 800 residents. and drifted E and SE. Source: Royal New Zealand Air Force via Brad Scott, GeoNet. Its rim drops steeply into the sea. Continuous ash emissions were observed by the Darwin VAAC through 11 January, drifting W and NW at 2.1 km altitude. Frequent gas and some ash emissions during May-December 2019 with some hot avalanches. Information was provided by the Rabaul Volcano Observatory (RVO), the Darwin Volcanic Ash Advisory Center (VAAC), satellite sources, and photographs from visitors. Heading rapidly E away from the eruption, he took additional photographs (figures 9-12). Both discrete eruptions and continuous ongoing activity was seen in satellite imagery through 9 January, with the plume visible at distances of over 200 km W and WNW. Overall vapor emission seemed much less than in earlier periods, and was more concentrated in a few main areas, with fewer of the weak but widespread vents evident in early 1977. Sangay Volcano Volcanic Ash Advisory: PSBL VA CLDS SEEN IN STLT. Rumbling could be heard from Blupblup (Rubrub) island, 15 km E, and residents there also observed incandescence at night. There are no samples for Kadovar in the Smithsonian's NMNH Department of Mineral Sciences Rock and Ore collection. the S coast, which may have been a small hydrothermal eruption or, more likely, a vigorous ebullition of gas bubbles. PUBLISHED: 18:01, Mon, Jan 8, 2018 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. and drifted ESE. and drifted W. Based on satellite data, the Darwin VAAC reported that during 7-8 October discrete ash puffs from Kadovar rose to an altitude of 1.8 km (6,000 ft) a.s.l. Scum was noticed on the water, persisting for a few days, and reddish coloration appeared on the rocks in the tidal zone at one point on the S coast. Based on satellite data and wind model data, the Darwin VAAC reported that during 10-12 October ash plumes from Kadovar rose to an altitude of 2.4 km (8,000 ft) a.s.l. Based on satellite and wind model data, the Darwin VAAC reported that on 30 July an ash plume from Kadovar rose to an altitude of 1.5 km (5,000 ft) a.s.l. 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. Thermal anomalies were visible at both the summit vent and the E-flank coastal dome in April and May 2018, along with steam and gas rising from both locations (figure 19). and drifted NW and N. Based on satellite data, the Darwin VAAC reported that on 4 October discrete ash puffs from Kadovar rose to an altitude of 2.1 km (7,000 ft) a.s.l. The MIROVA project recorded thermal anomalies from Kadovar in early January and early March 2018 (figure 16). A small double ash plume and two strong thermal anomalies at the summit were visible in satellite imagery on 24 February (figure 47). eruption series at Kadovar Island, Papua New Guinea during the period January to February 2018. While gas plumes were visible throughout May-December 2019 (figure 43), SO2 plumes were difficult to detect in NASA SO2 images due to the activity of nearby Manam volcano. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. 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. 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 Complete investigations, including temperature measurement, collection of gases and gas condensates, measurement of magnetic field, and seismic recording, were made during visits on 15-16 December (Cooke, Norris), and 16-18 February (Dent, Norris), and are planned for the forthcoming visit (Cooke, Norris). On clear days the plume was sometimes visible from Wewak, on the mainland 100 km W. Additional vents produced variable amounts of steam. Activity renewed at the SE Coastal Vent shortly after the collapse of the flow on 9 February 2018; lava re-emerged a few days later, connecting a lava island to the coastline again. Strong sulfur dioxide emissions were detected. Space Shuttle photo STS027-0032-0071 looking southwest along the coast of Papua New Guinea and across the offshore volcanic islands. The explosions ejected rocks and ash plumes that rose 300-400 m above the vent and drifted NE and E. Residents on Blup Blup (15 km N) reported rumbling and nighttime summit incandescence. However, another area of thermal activity (high on the E side of the lava dome) had produced a significant vegetation kill in the past few months. 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. Activity intensified on 5 July as emissions became dark gray and dense. Partial investigations were made on 3 April (Wallace), when temperatures and gases were investigated, and on 26 January (Mahar) and 14 February (volcanological assistant J. Kuduon), when temperatures were measured. The maps shown below have been scanned from the GVP map archives and include the volcano on this page. An incandescent lava flow slowly extruded from the SE Coastal Vent. McKee; 13-14 November, C.O. Weak earth tremors were felt, apparently during the preceding few days, and an explosive sound was heard. Intermittent puffs of ash were seen drifting WSW on 2 and 3 December at about 1.2 km altitude. Local visual observations determined that the Kadovar volcano began to erupt at the summit of the island, and then created new vent spots near the coast. The resulting plume of ash rising in the sky was spotted by air force New Zealand. The thermal anomaly was still strong at the E-flank coastal dome in a mid-June satellite image, but appeared diminished in late July. 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. When one is found the date, time, location, and intensity are recorded. Persistent pulsating steam plumes were visible whenever the skies were clear enough to see the volcano. A continuous white steam of plume is rising from the SE coastal vent from 400m to 700m above the island.

A seismic event counter was installed on the island. 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. There were some heightened thermal phenomena in 1976. There were some heightened thermal phenomena in 1976. | August A dormant volcano on Kadovar Island, northeast of Papua New Guinea, has erupted for the first time in known history, with a large plume of ash rising 2.1km above sea level, forcing the evacuation of over 500 residents. Throughout June cloud-free Sentinel-2 thermal satellite images showed elevated temperatures at the summit area and extending down the upper SE flank (figure 38). Visitor observations on 21 October 2019. A few volcano-seismic events were recorded in both November and December, but such events appeared to be absent in February. Noises were described as roaring and rumbling during 1-2 and 6-8 March, and booming on 5 March. 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 ( RVO reported minor eruptive activity at Kadovar during 1-15 July consisting of occasional light gray ash plumes of variable densities rising a few hundred meters above the summit crater. The maps database originated over 30 years ago, but was only recently updated and connected to our main database. A new ash plume clearly identifiable on satellite imagery appeared on 13 November at 2.4 km altitude moving E, again visible for about 24 hours. Papua – New – Guinea , Kadovar : 3.608°S, 144.588°E Elevation : 365 m. 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. The NOAA/CIMSS Volcanic Cloud Monitoring system generated an alert for an ash cloud moving WNW, as imaged by S-NPP VIIRS, at 0330 UTC on 5 January 2018; Himawari-8 imagery subsequently showed that the eruption began around 0220 UTC. The main part of the dome had bulged up, and a valley developed in between the dome and the island’s flank. An ash plume rose to 1.2 km (4,000 ft) a.s.l. Photo: NZ Airforce.

Ash and steam emissions from Kadovar were first reported on 5 January 2018. 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. Reports of continuous ash emissions at 2.1 km altitude drifting WNW from the Darwin VAAC resumed on 16 January. Kadovar volcano eruption on February 10, 2019. 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. 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). Kadovar is a volcanic island in Papua New Guinea north-east of the much larger island of New Guinea. An investigation [on 3 August] was made by Rabaul Volcano Observatory (RVO) volcanologists D. Wallace and R. Almond. Mr Isifu responded to concerns raised by the islanders regarding their daily struggles at the care centre in Dandan village on the Turubu coast, east of Wewak. The lava dome at the SE Coastal Vent continued to grow and was an estimated 50 m a.s.l. The original main fumarole may be a little reduced in intensity, although its temperature has not declined, remaining near 100°C. A dormant volcano that first began erupting on January 5 exploded on Friday, forcing the evacuation of hundreds of people from the Kadovar island in … The tremor was recorded early evening on Tuesday 5 January 2021 at 7:00 pm local time, at an intermediate depth of 104 km below the surface.

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. No volcano-seismic activity was recorded during 5.5 hours with a portable seismograph. A 1700 report of smoke seen briefly there was believed at the time to be a volcanic eruption. The Darwin VAAC reported on 6 January 2018 that a continuous ash plume was identifiable in satellite imagery moving W and WNW at 2.1 km altitude. A PAPUA New Guinea volcano has rumbled to life after many years dormant and hundreds of people have been evacuated. Kadovar: DISCRETE Volcanic Ash ERUPTION TO Flight Level 060 Movement Northwest Observed Volcanic Ash Date and Time 06/0404Z (2021-01-06 04:04:00 UTC) Darwin VAAC Post a Comment On each occasion, temperatures were measured, gases and gas condensates were collected, and seismic recording was carried out; a magnetic resurvey was made during the most recent inspection. The Observatory's acting assistant director Steve Saunders said a dome of lava had formed and reached about 200 metres out to sea. During January, small SO2 plumes were recorded by NASA satellites on four occasions (figure 17). Activity intensified over the next two weeks; RVO identified five distinct vents located at the summit and along the SE coast. There is no Deformation History data available for Kadovar. More than 500 people have been evacuated from the the tiny volcanic island after the eruption began without warning on Friday January 5. | March The main body of the flow significantly bulged upwards, with a distinct 'valley' visible between the bulge and the island's flank. 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 NW on 3 August. There was some heightened thermal phenomena in … 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. 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. Vulkanreisen VolcanoAdventures : Auf unseren Wander- und Studienreisen können Sie unter fachkundiger Führung aktive Vulkane besteigen, sich von Geologie, Natur und Kultur des Landes inspirieren lassen und dabei nette Menschen kennenlernen. A PAPUA New Guinea volcano has rumbled to life after many years dormant and hundreds of people have been evacuated. A summary of events to mid-November, and of investigations so far carried out, follows. Weak incandescence from the Main Crater was visible on 13 March. White steam plumes rose 100 m above the island and drifted SE. The steeply-sloped island is approximately 1.4 km in diameter and is located about 25 km NNE from the mouth of the Sepik River on the mainland of Papua New Guinea (figure 1).
