Pacaya Volcano, Guatemala
Pacaya volcano, Guatemala erupted yesterday. Strombolian eruptions occurred at the summit. Guatemala's President declared a state of "calamity" in two provinces and opened emergency shelters to accommodate over 1,700 residents who were evacuated. More than 65 people were injured, a television reporter killed, some people are missing, and hundreds of houses damaged by the eruption which sent stones and ash over a wide area. The international airport at Guatemala City was to remain closed for 20 hours. The runway was covered by 2.5 cm of volcanic ash.

Eyjafjallajokull volcano, Iceland
Eruptions have stopped at Eyjafjallajokull volcano in Iceland. Since Saturday, there have been no explosions at the summit, and tremor has almost reduced to pre-eruption levels. The have been no reports of ashfall, no lightning, and low water discharge from Gígjökull glacier. Renewed eruptions are possible.

Katla volcano, Iceland
In the past 48 hours 3 earthquakes occurred at Katla volcano, Iceland. The earthquakes may be due to ice movements within Mýrdalsjökull glacier or magma movement under the volcano. Scientists have been keeping a close watch on Katla volcano, due to the possibility of an eruption triggered by the activity at nearby Eyjafjallajokull. An eruption of Katla volcano has the potential to be more devastating than the current eruption of Eyjafjallajokull.

Eyjafjallajokull volcano, Iceland
Explosive eruptions continue at Eyjafjallajokull volcano in Iceland at a rate of 200 tonnes/s. On 18th May eruption plume reached a maximum height of 21,000 ft. Ashfall was reported in the Gnúpverjahreppur area, Hrauneyjar, Northeast and eastern Iceland. The civil aviation authorities of Britain and Ireland announced new rules for allowing aircraft to fly through small concentrations of volcanic ash. This announcement is overdue, because the original grounding of 100,000 flights for 6 days last month was an over reaction to the eruption of Eyjafjallajokull volcano. In other parts of the world, flights have been operating for many years through volcanic ash. The often quoted incident of an aircraft losing power to all 4 engines over Indonesia in 1982, was caused by the aircraft flying very close to Galunggung volcano, and was not 3000 km away as was the case in flights being grounded last month.

Eyjafjallajokull volcano, Iceland
Ash emission from Eyjafjallajokull volcano has forced the temporary closure of schools in southern Iceland. The eruption is still in the explosive phase. Ashfall was reported in Vik, southern Iceland on 8th May. Very little steam was observed at Gígjökull glacier on the northern side of the volcano. About 5000 flights were disrupted on Friday as ash drifted towards Europe.

Eyjafjallajokull volcano, Iceland
Intensified eruptions occurred at Eyjafjallajokull volcano, Iceland on 6th May 2010. Ash emissions reached a height of 30,000 ft, and caused cancellation of flights in Scotland. Melt water discharge has decreased from Gígjökull glacier in the west. New melt water discharge is flowing towards the east, which indicates a change in direction of lava flows. This could crate more hazardous floods. Explosions are increasing at the summit, and a cinder cone is forming in the crater. Tremor is similar to that seen in the phase of the eruption from 14-17 April 2010. On 6th May, there were 10 earthquakes detected under the volcano. Most earthquakes are located beneath or south of the summit crater.

Eyjafjallajokull volcano, Iceland
The first summit expedition to Eyjafjallajokull volcano, Iceland after the March eruption was made by John Seach in April 2010. While on the summit John observed two active vents inside the main crater. The southern vent was showing almost continuous Strombolian activity, and the northern vent showed phreatomagmatic eruptions. Intensified activity occurred under the Gigjokull Glacier on 1st May.
