Rumblings Continue at Cleveland Volcano
Stephanie Joyce
Two small explosions shook Cleveland Volcano on Friday. Scientists at the Alaska Volcano Observatory say the explosions didn’t produce detectable ash clouds. They’re just the latest in a series of low-level eruptions at the volcano.
There’s no real-time monitoring network on Cleveland, but scientists have been able to detect the eruptions using a network of distant air pressure gauges and seismic stations. Satellite images show slightly elevated surface temperatures in Cleveland’s crater, but the Observatory says there’s no sign of a new lava dome. The most recent dome was destroyed in an explosion two weeks ago.
The Observatory warns that unrest will likely continue at the volcano, with the possibility of sudden explosions accompanied by ash clouds exceeding 20,000 feet. Cleveland lies on a major international flight path and the aviation alert level for the volcano is at orange.
