Welcome to Volcano World!

Volcanic activity is the most powerful force in nature. Some volcanic eruptions are much more powerful than the largest nuclear explosion. Volcanoes have killed thousands of people and caused some of the most frightening events in human history.

This site includes information about volcanoes, their activity, and how they form and erupt.

Oct 22, 2024

Servicio Nacional de Geologa y Minera (SERNAGEOMIN) reported an increase in seismicity associated with rock-fracturing at Hudson starting at 1200 on 16 October, with a total of 160 volcano-tectonic earthquakes. The highest magnitude earthquake of 2.5 occurred at 1416 on 17 October, which was located 2.9 km ESE from the center of the caldera and at a depth of 4.4 km. A long-period earthquake was detected at 1638 on 17 October. A volcano-tectonic earthquake was detected at 0245 on 19 October. The Alert Level remained at Green (the lowest level on a four-color scale).

-
Oct 22, 2024

Servicio Nacional de Geologa y Minera (SERNAGEOMIN) reported nighttime crater incandescence at Copahue on 16 October. According to Servicio Geolgico Minero Argentino (SEGEMAR), webcam images recorded an increase in surface activity at 0430 on 19 October, which consisted of an ash emission that rose 200 m above the crater and drifted SE. The Alert Level remained at Green (the lowest level on a four-color scale) and the public was reminded to stay 500 m away from the crater.

Etna (Italy) - Report for 16 October-22 October 2024 - NEW

-
Oct 22, 2024

Sezione di Catania - Osservatorio Etneo (INGV) reported that during 14-20 October activity at Etna was characterized by continuous intra-crater explosive activity at NE Crater, mild and sporadic ash emissions from SE Crater, and degassing activity from the summit craters, based on webcam images. During 17-20 October weather conditions prevented clear observations. The Aviation Color Code was raised from Yellow to Orange at 1538 on 21 October.

Kanlaon (Philippines) - Report for 16 October-22 October 2024 - NEW

-
Oct 22, 2024

The Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported continuing unrest at Kanlaon during 16-22 October, characterized by elevated seismicity and sulfur dioxide emissions. Visual monitors recorded continuous degassing, with brief episodes when gray ash was entrained in the plume. Three ?ashing? events, at 0641, 0701, and 0801 on 19 October, lasted two to six minutes long, based on visual observations; no detectable seismic or infrasound signals were recorded. The events generated light-gray plumes that rose 500 m above the crater and drifted SW. Traces of ash deposits were reported in the barangays of Yubo and Ara-al, La Carlota City (14 km W), and Sag-ang, La Castellana (16 km SW). A sulfur dioxide odor was also reported in Yubo. The seismic network recorded 6-19 daily volcanic earthquakes. Daily gas-and-steam emissions that were sometimes voluminous rose 200-900 m above the summit and drifted W, SW, S, and SE. Sulfur dioxide emissions were recorded during 16-20 October and continued to be high, averaging 2,679-6,477 tonnes/day. The Alert Level remained at 2 (on a scale of 0-5) and PHIVOLCS reminded the public to remain outside of the 4-km-radius Permanent Danger Zone and warned pilots not to fly close to the volcano.

Spurr (United States) - Report for 16 October-22 October 2024 - NEW

-
Oct 22, 2024

The Alaska Volcano Observatory (AVO) reported that low-level unrest at Spurr was ongoing, characterized by elevated seismicity and deformation, and minor gas-and-steam emissions were visible in webcams. A small lake was present in the summit crater during 15 May to 15 June. The Volcano Alert Level was raised to Advisory (the second highest level on a four-level scale) and the Aviation Color Code was raised to Yellow (the second highest level on a four-color scale) at 1237 on 16 October.

Aira (Japan) - Report for 16 October-22 October 2024

-
Oct 22, 2024

The Japan Meteorological Agency (JMA) reported ongoing eruptive activity at Minamidake Crater (Aira Caldera?s Sakurajima volcano) during 14-21 October. Daily crater incandescence was visible in webcam images. An explosion at 0121 on 18 October generated an ash-and-gas plume that rose 1-4 km above the crater rim. The explosion ejected large blocks to a distance of 1.3 km from the vent. According to a field survey conducted on 18 October, sulfur dioxide emissions were measured at 2,500 tons per day (t/d). The Alert Level remained at 3 (on a 5-level scale), and the public was warned to stay 1 km away from both craters.

-
Oct 22, 2024

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that the eruption at Dukono was ongoing during 16-21 October. Daily dense gray-and-white ash plumes rose 100-800 m above the summit and drifted E and NE. The Alert Level remained at Level 2 (on a scale of 1-4), and the public was warned to remain outside of the 3-km exclusion zone.

Ebeko (Russia) - Report for 16 October-22 October 2024

-
Oct 22, 2024

The Kamchatkan Volcanic Eruption Response Team (KVERT) reported that moderate explosive activity was ongoing at Ebeko during 11-17 October. According to volcanologists in Severo-Kurilsk (Paramushir Island, about 7 km E), explosions during 16-17 October generated ash plumes that rose as high as 2.5 km (8,200 ft) a.s.l. and drifted NE. Thermal anomalies were identified in satellite images on 15 October; on other days either no activity was observed, or weather conditions prevented views. The Aviation Color Code remained at Orange (the third level on a four-color scale). Dates are UTC; specific events are in local time where noted.

Fuego (Guatemala) - Report for 16 October-22 October 2024

-
Oct 22, 2024

Instituto Nacional de Sismologia, Vulcanologia, Meteorologia, e Hidrologia (INSIVUMEH) reported that eruptive activity continued at Fuego during 16-21 October. Daily explosions were recorded by the seismic network, averaging 3-12 per hour when reported. The explosions generated gas-and-ash plumes that rose as high as 1.2 km above the crater rim and drifted as far as 30 km SW, SE, and S. Weak rumbling sounds and shock waves from explosions were occasionally reported. The explosions often produced avalanches of material that descended the flanks, sometimes reaching vegetated areas. On most days, explosions ejected incandescent material up to 200 m above the summit. During the afternoon and evening of 16 October lahars descended the Ceniza, Zarco, Seca, and Mineral drainage, carrying tree branches, trunks, and blocks as large as 1.5 m in diameter.
