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.

Gareloi (United States) - Report for 2 June-8 June 2021 - NEW

-
Jun 8, 2021

AVO reported that a minor increase in seismicity was first detected at Gareloi on 19 May. Beginning on 27 May the rate and size of small volcanic earthquakes increased and was sustained at that level. On 8 June AVO raised the Aviation Color Code to Yellow and the Volcano Alert Level to Advisory based on seismicity rising above baseline levels. Sulfur dioxide emissions had been identified in satellite images the past week, though they were consistent with measurements recorded in previous years. No other changes were evident in satellite or webcam views.

Semisopochnoi (United States) - Report for 2 June-8 June 2021 - NEW

-
Jun 8, 2021

AVO reported that low-level unrest at Semisopochnoi continued during 2-8 June with seismicity occasionally above background levels. Steaming from Mount Cerberus was sometimes observed by field crews. Slightly elevated surface temperatures were identified in a few satellite infrared images during 4-7 June. The Aviation Color Code remained at Orange and the Volcano Alert Level remained at Watch.

Aira (Japan) - Report for 2 June-8 June 2021

-
Jun 8, 2021

JMA reported that during 31 May-7 June incandescence from Minamidake Crater (at Aira Caldera?s Sakurajima volcano) was visible nightly and very small eruptive events were occasionally recorded. The sulfur dioxide emission rate was 2,700 tons per day on 2 June. The Alert Level remained at 3 (on a 5-level scale), and residents were warned to stay 2 km away from the crater.

Ebeko (Russia) - Report for 2 June-8 June 2021

-
Jun 8, 2021

According to volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, an explosion on 28 May produced an ash plume that rose to 4.5 km (10,500 ft) a.s.l. and drifted NE. A thermal anomaly was identified in satellite images on 2 June. The Aviation Color Code remained at Orange (the second highest level on a four-color scale).

Etna (Italy) - Report for 2 June-8 June 2021

-
Jun 8, 2021

INGV reported a few eruptive episodes at Etna?s Southeast Crater (SEC) during 31 May-6 June, as well as minor and diffuse ash emissions at Bocca Nuova (BN) and ash emissions on 4 June at Northeast (NEC). Weak Strombolian activity at SEC began at 0850 on 2 June and produced minor and diffuse ash plumes. The activity intensified at 1000; within 30 minutes lava fountaining was observed and lasted for over two hours. Ash plumes rose 5-6 km (16,400-19,700 ft) a.s.l. and drifted E, causing ashfall in Petrulli, Santa Venerina, and in an areas N of Zafferana. Lava overflowed the S side of the crater and traveled W. Fountaining stopped at 1245. Weak Strombolian activity continued to be observed during the night hours of 3-4 June. Activity increased at 1530 on 4 June and was characterized by discontinuous ash emissions and lava overflowing the S rim of SEC. Lava fountaining began at 1820 and an ash plume rose to 6.5 km (21,300 ft) a.s.l. Tephra fell in Aci Castello, Acitrezza, San Giovanni La Punta, Tremestieri, Catania, and Viagrande, and between Pedara, Fleri, and Siracusa. Fountaining began to decline at 1930. The lava flow continued to advance, and by 2300 had reached 2,800 m elevation. Occasional ash emissions were noted during 4-5 June, and the lava flow had ceased.

Fuego (Guatemala) - Report for 2 June-8 June 2021

-
Jun 8, 2021

INSIVUMEH reported that 5-13 explosions per hour were recorded during 1-8 June at Fuego, generating ash plumes as high as 1.1 km above the crater rim. Shock waves often rattled buildings around the volcano. Ashfall was reported almost daily in several areas downwind, including Morelia (9 km SW), Panimach I and II (8 km SW), Santa Sofa (12 km SW), El Porvenir (8 km ENE), Sangre de Cristo (8 km WSW), and San Pedro Yepocapa (8 km NW). Block avalanches descended the Ceniza (SSW), Seca (W), Trinidad (S), Taniluy (SW), Las Lajas (SE), and Honda drainages, often reaching vegetated areas. Explosions ejected incandescent material 100-350 m above the summit on most days.

Jun 8, 2021

KVERT reported that a thermal anomaly over Karymsky was visible in satellite images during 28-31 and 2-3 June. The Aviation Color Code remained at Orange (the second highest level on a four-color scale).

Kerinci (Indonesia) - Report for 2 June-8 June 2021

-
Jun 8, 2021

The Darwin VAAC reported that on 6 June an ash plume from Kerinci rose to 4 km (13,000 ft) a.s.l. and drifted WNW. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 3-km exclusion zone.

Krysuvik-Trolladyngja (Iceland) - Report for 2 June-8 June 2021

-
Jun 8, 2021

The fissure eruption in the W part of the Krsuvk-Trlladyngja volcanic system, close to Fagradalsfjall on the Reykjanes Peninsula, continued during 2-8 June. The flow rate at the fifth vent, now the main lava source, was 12.4 cubic meters per second by 3 June, similar to the 11-13 cubic meters per second measured in May. Cycles of lava fountaining followed by no activity persisted at the fifth vent, though observers noted that the vent opening was getting smaller as the crater walls thickened. One observer described standing waves of lava 20 m high during a period of greater lava effusion. Lava advanced in the Ntthaga, Geldingadalur, and Merardalur valleys. The flows in Ntthaga continued to get closer to Highway 427 (Suurstrandarvegur) to the S, covering an area with buried fiber optic communication cables. The leading edge of the flow ignited vegetation, causing small fires. The Aviation Color Code remained at Orange due to the lack of ash and tephra emissions, though IMO warned of the potential for lapilli and scoria fallout within a 650 m radius of the active vent. Authorities warned of increased gas emissions hazards.

Lewotolok (Indonesia) - Report for 2 June-8 June 2021

-
Jun 8, 2021

PVMBG reported that white-and-gray plumes from Lewotolok rose as high as 500 m and drifted W and E almost daily during 1-8 June. Rumbling was heard every day. Crater incandescence was visible during 1 and 3-4 June. Incandescent material was ejected as far as 300 m in all directions during 3-4 June and as far as 1 km NW during 5-6 June. The Alert Level remained at 3 (on a scale of 1-4) and the public was warned to stay 3 km away from the summit crater.
