Colo, Sulawesi, Indonésie: seismicity at Colo declined .

PVMBG reported that seismicity at Colo declined during 1 September-25 October; 1-7 shallow-volcanic earthquakes and 1-3 volcanic earthquakes were recorded per day, which were rates similar to those recorded before a seismic increase in June. The Alert Level was lowered to 1 (on a scale of 1-4) on 26 October, and residents and tourists were warned not to approach the crater.

Colo volcano forms the isolated small island of Una Una in the middle of the Gulf of Tomini in northern Sulawesi. The broad, low volcano contains a 2-km-wide caldera with a small central cone. Only three eruptions have been recorded in historical time, but two of those caused widespread damage over much of the island. The last eruption, in 1983, produced pyroclastic flows that swept over most of the island shortly after all residents had been evacuated.
