Fabij de Oostkust van Java bevindt zich een ongeveer 450 m bo-ven den oosteli jken Kawah Id jenrand uitstekende kegelberg, die of-schoon uitgedoofd, Merspi genoemd wordt. Merapi en Kawah Id jen vor-mer saren een tweelingvulkaan (Plaat 2, A-B), ontstaan door een kra-terverplaatsing naar het Ww over een afstand van bijna 2 km. Taverne (1926, p.99) wees op de overeenkomst van deze tweelingsvorm me…
The wedusgenbels originated because big amounts of gas-rich, but toughliquid magna were ejected, came down along the volcano slope and landed in the very deep ravines, which are situated in the mountain foot on ca. 1400 na.s. Due to their great mobility they have still covered considerable distances in the terrain gullion. It is striking through which sharp turns (portrait 7, 8 and 10), particu…

During the rest period of a few years, the lava han been actually s…
By the paroxismal phenomena on December 18 and 19, 1930 in the W wall of the mountain summit a breach originated with a length of 1350 π. This reached an elevation of 2150 a downwards and near the summit it was about 200 m in width. A big part of the old domes on the summit, including the lavastream of 1922 has disappeared.
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.
