1988 Earthquake Swarm
The epicenter distribution and volcanic–tectonic character of the earthquakes was similar to the 1984 swarm. This indicated there was movement of magma at shallow depth under the volcano.
The distribution of epicenters from the earthquake swarm define a North 45 deg West trend, 16 km long and 8 km wide extending from Belkofski Bay to beneath the volcano.
No eruptive or fumarolic activity has been reported from Mount Dutton volcano in historic time (since late 1700's).
No recent eruptions.
