When we travel the area between Lunajang and Pasirian and the S foot of the volcano till the Kali Glidik, then it becomes clear to anybody which role the aquatic transportation of the Semeru products fulfils in the economic life of the here established populat…

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 Eruptions In Kawah Baru, G.Papandayan In 1924, The Activity In Kawah Nang…

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…

The G. Lamongan

Although several times from the surroundings of the Lamongan nevs arrived on eruptions of the volcano, after further investigation appeared, that the observed abnormal phonomena are not to be ascribed to volcanic activity.

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…
