Here are extracts from the four Redoubt seismograph traces made available on the Alaska Volcano Observatory website, showing the signals generated by the eruption that began a few hours ago. The three explosive pulses recorded by the AVO are particularly clear on the REF trace.
The latest seismic traces (it’s now 01:40 local time, 09:40 GMT) indicate that activity has quietened down again. UPDATE, 02:01 local time, 10:01 GMT: another sizeable burst of tremor is under way; AVO reports a fourth large explosion beginning 01:39 local time.
