The eruptions, which in the course of 1924 took place in Kavah Baru, were all of relative short duration. In many cases the activity was restricted to the geyserlike spouting-up of mud from one of the crater openings, which in the course of 1923 were born. Sometines also new craterlats were formed, or except mud also stones were ejected. Naturally the gaspressure at lastnaned eruptions was much…
Of more importance than the flank eruptions are the excentric eruptions, which are fed from a much more deeper lavaniveau than the first mentioned, whereas the breakthrough mostly takes place in the area of the volcano foot. Also excentric eruptions may entirely independently become active fron the main crater, which at flankeruptions is not likely possible. Also the phenomena, with which excen…

In April 1960 a series of strong tectonic earthquakes took place in the vicinity of the Colo volcano on the island of Una-Una situated in the Gulf of Gorontalo, Central Sulawesi. Unlike that of 1898 these earthquakes were not followed by an eruption of the Colo volcano but only caused a slight incresase in temperature of the solfatara fields. Strong earthquakes were again felt in August 1982, g…
