The alert level of Shishaldin revised upwards .

The alert level of Shishaldin volcano has been reassessed  to WATCH and Orange on 03/28/2014 by the AVO .

Elevated surface temperatures was detected from March 18 by satellites , and persists to this day , in relation to the presence of lava in the summit crater . Seismographs record small explosions intermittently since the same date. The activity remains confined in the deep crater without flows on the flanks .

The Shishaldin is the highest volcano of the Aleutian volcanic arc,  with his top at 2.857 meters. This symmetrical stratovolcano, located on Unimak Island , has a basal diameter of 16 km. and a small summit crater from which emerges a permanent small plume of steam. It is flanked to the northwest by 24 monogenic cones parasites.

The Shishaldin cone is relatively recent, less than 10,000 years , and is built on the remains of an ancient somma eroded by glaciers, and based on volcaniclastic rocks of late Tertiary .

Its last eruption was in 2004 ( GVP )

Aleuts call this volcano Sisquk , meaning " mountain pointing the way when I 'm lost ."
