| Summary: | Mount Erebus is an active volcano with a persistent convecting lava lake at the summit crater, located on Ross Island, Antarctica. Since December 1980 the seismic activity of Mount Erebus has been continuously monitored using a radio-telemetered network of six seismic stations. A 50-day temporary seismic observation was also carried out in the 1982-1983 Antarctic field season. The following seismic activities were observed during this field season : 1) Explosion earthquakes accompanied with Strombolian eruptions from the lava lake occurred at a rate of 0-4 times per day which is slightly lower than the rate in the previous season; 2) an intense earthquake swarm, which is possibly related to the underground movement of magma, occurred in October 1982 near Abbott Peak, 10km northwest of the summit; 3) there were other source regions of seismicity in Ross Island, fairly distant from Mount Erebus to the east. |
