Tungurahua volcano erupted violently on 08h47 local time on May 28, 2010, producing an vulcanian-style ash plume rising about 10 km above the crater and drifting SW until the Gulf of Guayaquil. The flanks of the volcano were showered with incandescent bombs, and ballistic projectiles fell into inhabited areas such as Chonglontus, Manzano and Yuibug on the W and SW slopes. ...plus [lire toutes]

Yasur's activity has continued to be very violent, with explosions that often throw bombs onto the visitor's rim and as far as the parking lot. This caused the Department of Geology, Mines and Water Resources from Port Vila to raise the alert level to 3 (out of 4) on 27 May.
On the evening of 27 May, Pacaya volcano entered a phase of violent lava fountaining reaching an height of about 1 km, and an ash plume reaching about 3-4 km elevation drifting north-west towards the capital. ...plus [lire toutes]

Chiveloutch volcan continue à être très active et le dôme de lave est en croissance. Une éruption explosive de la coupole, le 26 mai a envoyé un panache de cendres à 4500 mètres d'altitude.
KVERT reports that Bezymiany's activity has been increasing, promting to raise the alert code from Yellow to Orange, which means that a new eruption could happen in the near future. Although the seismic data are blurred by the activity of nearby erupting Klyuchevskoy volcano, Bezymiany is showing an increase in earthquakes as well as an increase in the temperature in its crater, the usual preceding signs of new activity.

Arenal volcano in Costa Rica had a stronger explosive and/or effusive eruption around 1pm on 25 June. According to various news sources, explosions produced 8 ash avalances (or lava flows) and promted the evacuation of parts of the Arenal National Park. Although almost constantly active during the past decades, the last major eruption of Arenal was in 1968 when 89 people got killed.

Rinjani volcano erupted again on Saturday and Sunday (22-23 May, 2010), sending ash to up to 2 km height and causing ash falls in surrounding villages. New reports mention lava flows from the active Baru Jari cone inside the Rinjani caldera into the lake. No fatalities or major damage were reported.
It seems that the eruption of Eyafjallajökull volcano has finally ended. While ther is stilla considerable steam plume rising from the crater, no fresh ash or lava emissions have been observed since yesterday (23 May). The measured heat flow from the crater is low and seismic activity has continued to decrease as well.

Eyafjallajökull volcano is getting more quiet and perhaps the eruption is coming to an end. As the Icelandic Meteorological Office and the Institute of Earth Sciences confirm in their latest bulletin, the magma output rate has decreased to an estimated 5 tons per second, around 10% of what it had been a week ago and during the peak phases of activity. The plume has decreased to 1.5-3.5 km and contains relatively little ash. Seismicity has been decreasing overall.
The intensity of Eyafjallajökull's eruption has been decreasing. Observations from flights show that the eruption plume is light grey, with a small amount of ash and the height is 3-3.5 km/10,000-12,000 ft (a.s.l.), about half of what it had been a week ago.

The intensity of Eyafjallajokull's eruption is slightly decreasing, although the ash plumes are still reaching 5-6 km (18,000-20,000 ft) height according to radar and pilot observations. However, it would be too early to conclude that this means that an end of the eruption is in sight.

Eyjafjallajøkull volcano (Iceland), eruption update: strong ash emission continues, ash plume to ca. 7 km height
Eyjafjallajøkull continues to erupt. According to radar observations, the eruption plume has been mostly at 7 km (21,000 ft) height and drifting NW. It is estimated that the eruption output is as high s 200 tons per second. Ashfall in some areas of southern Iceland is becoming an increasing problem.

In their latest bulletin on 11 May 2010, INGEOMINAS warns of a possible new eruption in the near future at Nevado del Huila volcano, after recording an alarming number of seismic events under the volcano and an important SO2 emission, which likely shows magma movements inside the volcano.

The eruption in Iceland continues with little changes. Eyafjallajokull volcano continues to emit dense graz ash reaching a height of 7 km (24,000 ft). Currently, the plume is drifting west and southwest, causing ashfall on the Vestmannaeyjar islands, Rangárþing eystra and in Reykjavík.

The eruption at Eyjafjallajøkull volcano continues with little changes, although the strength of the ash emission has slightly increased again. The plume is now reaching 6-9 km altitude and carried in southerly directions by presently weak winds. ...plus

Yasur volcano's activity continues to be dangerously strong. Explosions frequently throw bombs outside the crater onto the rim, the outer flanks and even as far as the ash plane and the parking lot. Alert level remains at 2, as the Department of Geology, Mines and Water Resources from Port Vila stresses in their latest bulletin about Yasur.

Eyjafjallajøkull volcano (Iceland), eruption update: lava flow from summit, increased ash explosions
The eruption in Iceland has increased again. After large explosions on 3 May at 14h30 produced ash plumes of up 5-6 km height, parts of this ash are now drifting over Ireland and Britain, forcing again a partial closure of airspace and cancellation of numerous flights this morning. ...plus [lire toutes]
