On 10 April 2011, the activity which had started with weak strombolian activity from the collapse carter on the east foot of the SE crater evolved inot a new, violent and spectacular eruption (paroxysm), including lava fountains, 3 km long lava flows and a tall column of ash. This was the 3rd such event in 2011. ...more [read all]

Lava returned to the crater floor of Pu`u O`o crater this morning, covering it with a small lava lake. The new eruptive episode marks the end of one of the longest pauses in the eruption so far. It followed a day of inflation, first at the summit, then under the eastern rift zone, indicating the rise of underground magam filling the plumbing system again. [read all]

INSIVUMEH reported that during 17-18 and 20-22 March explosions from Fuego produced ash plumes that rose 300-600 m above the crater and drifted 5-8 km W, SW, and S. Incandescent material was ejected as high as 100 m above the crater. Avalanches traveled SW, into the Taniluyá, Santa Teresa, Ceniza, and Trinidad drainages. ...more [read all]

Elevated activity continues at Santiaguito, as recent visitors and the latest reports from INSIVUMEH confirm. The Santiaguito lava dome has been producing frequent ash explosions with plumes to 700-800 m height and small avalanches and pyroclastic flows traveling down the eastern and southern flanks of Caliente dome.

A powerful lahar (mud flow) occurred on 21 March on the SW flank of Merapi volcano. A lahar traveled through the village of Sleman, approximately 20 km SW of Merapi, burying 21 homes in addition to vehicles and livestock. At least 200 residents were evacuated. [read all]

Mild explosive activity at Batu Tara continues. Darwin VAAC reported an ash plume from Batu Tara volcano on 20, reaching an altitude of 2.1 km (7,000 ft) a.s.l. and drifting NE. ...more [read all]

The activity of Karangetang volcano is increasing. The Indonesian Volcanological Survey has raised the highest level of alert (4), after pyroclastic flows (block and ash flow type) from the new growing lava dome on the summit into the Kali Kali Nanitu und Pangi valleys have have reached nearly 4 km distance from the crater on 18 March. 3 villages have been ordered to evacuate.

The east rift zone, site of the recent spectacular eruptive episode in Napau crater, is still pausing. No lava is being erupted at present. Also the lava level inside the Halema`uma`u vent has dropped and the summit has been deflating in recent days. Is this the end of one of history's longest-lived eruptions documented ever, or simply a pause? The following weeks will probably tell. ...more [read all]

Kirishima volcano near Kagoshima town on Kyushu Island exploded violently earlier today (13 March), sending an ash plume to 4 km elevation. This is the first significant activity since March 1. It can not be ruled out, but probably remains speculation that the violent 8.9 magnitude earthquake on 11 March played a role in the reawakening of Kirishima. [read all]

A new eruption started at Karangetang volcano yesterday 11 March (the day the massive Japan earthquake markes history). Karangetang is located on the remote Island of Api Siau north of Northern Sulawesi in Indonesia. Most likely, the new activity consists of strombolian activity, and perhaps intermittent phases of lava fountaining. ...more [read all]

After several days of activity, the Kamoamoa fissure eruption in the Napau crater on Kilauea's E rift zone has stopped or paused. Lava emission stopped late on March 9 local time. Both the rift zone and summit are showing deflation and seismic tremor and SO2 output were diminishing, indicating a temporary exhaustion of magma supply in the shallow reservoir. ...more [read all]

Ruapehu volcano who last erupted in 1995-96 might be heading towards a new eruptive cycle. The temperature of the crater lake has increased to 40C and other indicators such as seismicity and deformation all point towards a gradual reawakening. [read all]

A major change in Kilauea's eruption is in progress starting several hours ago. ...more [read all]

Early on 20 June, a new series of ash eruptions started at Bulusan volcano, producing a 3 km / 9,800 feet high plume. Ashfall spread to as far as 30 km away in Masbate and the noise from the explosion was heard up to 10 km from the volcano. ...more [read all]

A second paroxysmal eruption occured at Etna's SE crater on 18 February, 36 days after the previous one (12-13 January 2011). The eruption started around 3am and lasted 11 hours. It could not be well observed due to bad weather, but consisted of strong Strombolian activity and pulsating lava fountains, feeding a flow that superimposed itself on the path of the previous flow from January. ...more [read all]

As observed on location today, Bromo erupts dense clouds of ash, rising to about 1 km above the crater, drifting east. The emissions fluctuate in intensity with phases of weaker and strong emissions alternating ca. every 20 minutes. The activity is often accompanied by near continuous roaring noises resembling a strong surf. During stronger phases, loud explosions sounds heard in many kilometers distance as well as shock waves rattling windows in nearby villages accompany the eruptions. [read all]

As observed during the past two days, Anak Krakatau is still active, with weak ash emissions at irregular intervals ranging from several hours to 10 minutes, with about 10 estimated as a daily total. We observed maximum plume heights of 500-1000 m, and rocks projected no further than the summit cone itself. At night, no incandescence was visible. [read all]

It's an exciting time on Kilauea, with high magma pressure forcing lava to the surface in four locations: the Overlook Vent in Halema`uma`u (within 90m of lowest rim, causing intense night-time glow visible from a distance), within Pu`u `O`o crater, from the TEB vent and satellitic ponds, and at the flow-front in Kalapana, where active lava is typically present and legally accessible to our clients. This excess pressure has also caused many earthquakes in the upper east rift zone, the rising of the Halema`uma`u lava lake, and a collapse of the pyroducts carrying lava to the ocean, where the sea entry has ceased for now. Join us to learn more about the ongoing eruption of Kilauea! [read all]

The VAAC Darwin reports an ash plume from Bromo's eruption rising to 26,000 ft (ca 9 km) drifting 90 nm NW reaching Surabaya. A low-level plume at 10,000 ft (ca. 3 km) is drifting 20 nm SE. [read all]

Mild explosive activity continues at Bromo volcano, with a sustained plume of ash reaching 400-800 m above the crater and incandescent material visible at night, according to local news sources. ...more [read all]

Another Icelandic volcano might be preparing itself for a new eruption. Bárdarbunga, a large central volcano at the NW end of the massive Vatnajökull ice cap, has recently shown increased seismic activity, the Icelandic Met Office is reported in an article of the Telegraph. These could be precursors to new activity. After all, Bárdarbunga is one of Iceland's most active volcanoes and is located quite on the center of the Icelandic hot spot. Its last eruption was in 1902-03. ...more [read all]

As our correspondent Doni living near Bromo volcano reports, the volcano is "still very active you can see strombolian eruptions". Explosion sounds can be heard in up to 28 km distance. ...more [read all]

Over the past days, Kirishima's overall intensity of the eruption seems decreasing. Kirishima continues to grow its lava dome and produce small to moderate vulcanian-type explosions at rates of 5-10 per day. Strong pressure waves were accompanying the explosions and could be felt in Kirishima town. People are alerted not to approach the volcano in a radius of 4 km because of the risk of falling bombs. ...more [read all]

Another powerful vulcanian explosion from the new lava dome occured today at 15:54 pm. Ash reached an elevation of 15,000 ft (ca. 5 km) and an aviation warning was issued by VAAC Tokyo. ...more [read all]

Kirishima volcano had a strong explosion from the lava dome on 31 January. Windows were shattered by the pressure wave up to 8 km away, and bombs landed up to 2 km distance. Authorities have extended the exclusion zone to 4 km from the crater as new explosions can occur any time. ...more [read all]

The lava dome inside Kirishima's crater is growing at a fast rate. Judging from areal photos, it now more than 500 m wide and well under way of soon over-spilling the Shinmoe-dake crater. If this happens, pyroclastic flows will likely be generated and could threaten nearby areas; although explosive activity has calmed down a lot, large explosions could occur any time. For this reason Japanese authorities have extended the exclusion zone from 2 to 3 km, and evacuated more than 600 residents of the town of Takaharu located on the eastern slope of Kirishima volcano. ...more [read all]
