Eruptions have decreased at Eyjafjallajokull volcano in Iceland. Yesterday the eruption plume reached a height of 12,000 ft. No explosions are occurring at the summit and no lava is flowing from the crater. There were two hours of elevated tremor yesterday. No lightning has been observed since 13:00 hr on 20th May, local time.

Yesterday marked 10,000 days of the current eruption on the east rift zone of Kilauea volcano, Hawaii. The east rift zone began erupting 3rd January, 1983, and Halemaumau crater at the summit has been erupting since 9th March, 2008. Lava is currently flowing into the sea west of Kalapana.

Ash emissions from Eyjafjallajokull volcano in Iceland reached a maximum height of 27,000 ft on 15th May. An earthquake swarm was recorded beneath the volcano between 23:54 hr (14th May) and 02:45 (15th May). Over 30 earthquakes less than magnitude 2 were recorded at a depth of 30 km. Lightning continues to be recorded in the eruption plume with a rate of about 30 strikes per day. Ash emissions from Eyjafjallajokull volcano are expected to drift over parts of Scotland on Sunday and the rest of UK on Monday, causing flight disruptions.

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.

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.

Eruptions have decreased at Eyjafjallajokull volcano in Iceland. Present magma eruption rate is about 75 tonnes/second which is about 10% of the 72-hour long maximum phase. Phreatomatic eruptions continue from the northern crater, and a plume is reaching an altitude of 3 km. About 100 million cubic meters of material has been erupted so far. Ash fall is 30 m deep near the crater. There have been no changes in crater size since 19th April. A total of 100,000 flights were cancelled because of the eruption.

Flights have resumed to airports in Scotland and northern England today, and airports are expected to reopen in France and Germany later in the day. Eruptions continue from Eyjafjallajokull volcano in Iceland, with ash emissions to 4500 m altitude.

Some flights over Europe are planned to resume today. The eruption of Eyjafjallajokull volcano in Iceland has grounded flights over many parts of Europe for 5 days. The response is looking like an overreaction, as planes have regularly flown through volcanic ash clouds in other parts of the world for many years. With Eyjafjallajokull volcano possibly staying active for months or years, a more appropriate response will need to be found for the next occasion. The response will need to be based on science, and include a multi-disciplinary approach. Hopefully there will be increased funding for volcanology research as a result this eruption of Eyjafjallajokull volcano.

Ashfall is occurring in Iceland from the eruption of Eyjafjallajokull volcano. Between midnight and 4:30 am today volcanic lightning was recorded 22 times, and earthquakes were measured between magnitude 1.2 and 2.3. The eruption continued with force last night, with the ash reaching an altitude of 8.5 km. Heavy ashfall is occurring at the base of Eyjafjallajokull glacier.
