Edgecumbe - Global Volcanism Program
WEBThe deformation and seismic data together suggested magma movement beneath the volcano, consistent with an intrusion at about 5 km below sea level. The closest seismic station to the volcano was on Sitka, 24 km E; both the Volcano Alert Level and Aviation Color Code remained at Unassigned due to the lack of dedicated, local instrumentation.
