Volcanoes with an entirely different character, which frequently caused gigantic destructions, are those which outbursts wen acampamied by wedusgembel.
Ten einde een juiste beeld te krijgen van werkingvan den Semerce is de onderstaande, lijst en grafiek (Plaat ) samengesteld uit de geschriften welke ter be-schikking staan. Daaruit blijkt niet, dat de vulkaan voort-durend gewekt heeft, wel echter dat hij herhaaldelijk uitbars-tingen heeft vertoond. Zeer zeker is de lijst onvolledig en de eruptieve werking telkens van langer duur geweest, dan hi…
After the volcanic destruction in 1931 the W foot of the mountain was harassed by heavy banjirs, which beat in pieces the bridges and covered fields with sand. The banjir problem of the Merapi was studied in detail by K.G.R. Schmidt, a separate detailed report about this is in preparation by him.
A good 20 km2 terrain, with 13 kampungs completely and 20 kampungs has partly destroyed by the big eruptions of December 18 and 19, 1930, causing 1369 men and a good 2100 big cattle killed and more than 1100 house lost.
After the December eruption 1930, the laducourses of Merapi Volcano, Central Java previously showed no water circulation, expect at big rainfall, which caused shorthliving banjirs.
The ladumasses were deeper cut in the course of the mouths and it appears always clearer, that they were built of a heterogen, lightbrown colored sand mass, where in-between irregularly scattered, the stones occurred as individuals or as bouldertrails.
Almost all authors are the opinion, that the well - known wedusgembel, which caused death and destruction on the western slope of the Merapi, originated from the hot lava avalanches (glowing avalanches), which rolled down along the slides, whereas 'shout-out' wedusgmbel have not taken place.
Pengukuran kubah lava ini bertujuan untuk mengetahui volum pen-dekatan. Penulis memberi istilah volum pendekatan disini, karena berdasarkan atas sifat pengukuran pengukurannya, antara lain s a. pengukuran puncak kubah lava baru dengan cara aanpeilingen" jarak jauh dari dua titik totap (titik pengamatan) G. Sasur dan Sumberbulus (PANDI. K., 1977). b. disesuaikan dengan seket dari potret ba…
As mentioned, during the observation, extensive temperature observations were carried out. From this on the first place appeared, that within the crater groups of solfatara's and hot springs can be distinguished, which temperature strongly varied. The distribution of the temperatures is for a fixed day (September 2, 1924) given on Plate II. We see from this, that the highest temperature occurre…
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.
