Alaid is the tallest and northernmost volcano in the Kurile Islands. The symmetrical stratovolcano rises 3000 m from the sea floor and forms a small island. It has a 1.5-km-wide summit crater breached to the south. It is one of the Kuriles' most active volcanoes. Large explosive eruptions occurred in 1790 and 1981, and were among the largest in the Kuriles in historic times.
KVERT lowered the level of activity of the stratovolcano back to normal ("green"). ...more
During the month of October 2012 thermal anomalies and significant degassing were observed. Between October 27 and November 8 eruptive activity had left a deposit of ash on the summit of the cone, indicating explosive activity inside the crater that has built a small cinder cone. The seismic network that was put in place in early Dec measured strong volcanic tremor, but shortly afterwards seismicity decreased again. Since 12 December the volcano no longer showed any signs of activity, which is why KVERT lowered the alert level yesterday again. [less]
