Eyjafjallajokull volcano, Iceland - John Seach

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.

Aviation Hazards from Volcanic Ash - John Seach

The grounding of 17,000 flights from the eruption of Eyjafjallajokull volcano in Iceland highlights the hazard of volcanoes to aircraft. The total closure of British airspace is unprecedented. Since 1980 about 5 airports per year have been affected by eruptions. The largest number of closures have occurred at Catania (Sicily), Anchorage (Alaska), Quito (Ecuador), and Tokua (Papua New Guinea). About 20% of the airports closed were more than 500 km from the volcano. Since 1973 there have been at least 100 incidents involving aircraft and volcanic ash emissions. In 1982 an aircraft flying over Galunggung volcano in Indonesia lost power from all four engines, and descended 12,000 ft before the engines were restarted. In 1989 an aircraft flying over Redoubt volcano in Alaska encountered volcanic ash, damaging engines, which required replacing. The current situation in Europe will need to be analysed to determine if the widespread airport closures were an overraction, or justified based on volcanic activity. Caution is always advised when it comes to volcanic activity, but what will be the response next time this type of event occurs? The last eruption of Eyjafjallajokull volcano lasted for more than a year, so there is a possibility that more ash emissions will occur.

A significant eruption is continuing at Eyjafjallajokull volcano in Iceland. Ash emissions are reaching 28,000 ft altitude. Yesterday there was a glacial outburst, and water level in Markarfljót rose by 50 centimeters at 6pm. There was another glacial outburst earlier in the day at Gígjökull glacial tongue. More glacial bursts are expected as the eruption continues. Roads are closed near Fljótsdalur, the old Markarfljót bridge on highway number 1, and near the villages of Vík and Kirkjubaejarklaustur. The road between Vík and Kirkjubaejarklaustur was opened at 4 pm yesterday but remains closed by Hvolsvöllur and Skógar.

All flights in the UK have been grounded due to ash emission Eyjafjallajokull volcano in Iceland. This is the first time that British airspace has been totally closed. The eruption has caused the cancellation of 17,000 flights. Travelers have been stranded in Australia, USA, and Europe as connecting flights to Europe have been affected. Clearing of the ash will depend upon the eruptions at Eyjafjallajokull volcano and wind direction. More of the glacier has begun to melt and there have been further evacuations. The damage to the main highway which circles Iceland is extensive. Will neighbouring Katla volcano erupt, as it has at the past two eruptions of Eyjafjallajokull?
