The G. Lamongan in 1924

The crater of the Lamongan vas visited for the last time in July 1925. Although since that tine no reports on abnornal phenomena were received, the crater was again reconnoitred at the beginning of February 1924, as we must be always on our alert, that the rostful situation of these previously so active volcano suddenly might change.

The Kelud, Volcanic Earthquakes At Lamongan Volcano In 1924

Volcanic quakes occurred since September 20,1924. E and Ne of Ranu Klakah treasures were formed. The tromometers Klakah repetend in October 135, in September 81, in December 105 shocks.

The Lamongan in 1922

During 1922 the G. Lamongan was often visited by the volcano guideship survey namely in April, June and August.

On Plugforming and The Eruption Character of G. Merapi

The summit of G. Merapi is formed by a lava-plug; a cratershaped decline, such as the most volcanoes possess, is not present. However it is known,-thanks to the many interest, with which the G. Herapi in the pant century obtained, that the volcano in another stage of eruptive activity certainly owed such a cratershaped decline.

Small Eruption on December 6-7, 1920 in the Craterlake of G. Kelud

Except by the already quite quickly after-supply of water in the crater established calving off of the craterwall, the topography of the crater and therefore the correctness of the calculation of the supplied water was much more seriously hindered by a small eruption in the craterlake, which took place in the night of December6 to 7, 1928 (The big eruption lasted May 1920, 1919. Translater).

The G. Kelud in 1924

Phenomena which would indicate on an increased activity on the Kelut were not observed during 1924 and in the beginning of 1925. A fow light earthshocks, which were felt in the lowercamp, appeared to be of tectonic origin.

Excentric Eruptions of G.Lamongan

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…
