Alaska Volcano

September 8, 2011 by USA Post 

Alaska VolcanoAlaska Volcano, ALASKA-Mount Cleveland, a stratovolcano perched on Chuginadak island has had its alert status of the volcano raised back up to “View” aviation code and rose again to the “Orange”.

This comes as the observations of the volcano yesterday that the small lava dome in the summit crater growth has resumed and now fills the crater floor.

A persistent thermal anomaly has been observed since September 3, probably marks the time when growth resumed lava dome. The size of the dome to August 30, when it seemed to have stopped growing was about 262 feet in diameter. The present dome is about 394 meters in diameter. If growth continues dome lava flows on the volcano can be developed, but it would be dangerous to aviation. The presence of the lava dome increases the possibility of an explosive eruption, but not necessarily indicate that one will occur. Short-lived explosions may produce ash cloud that is over 20,000 feet above sea level. These events can occur without warning and can be detected in satellite images for hours.

The team from the Alaska Volcano Observatory was not sure on September 2, if the earthquake had disrupted rest 6.8 Apparent volcano. However, satellite information began to arrive the next day as the first of the anomalies and the low quality of the volcano released. That information was hidden by the volcano cloud cover so we could not determine the continuation. It was not until yesterday that a better view from the summit of the volcano could be seen.

While no connection has been established, the 6.8 earthquake and its many and after the crisis was felt from 02 September, may well have been responsible for the current activity on Mount Cleveland.

There was another shock after the earthquake of September 02 again this morning at 2:36 a.m. measuring 4.4 in magnitude.
