Οnlangs ontmoetten wij dr. M. Hartmann, en wat kan een journalist die enkele keeren met hem lief en leed deelde op den Merapi, in zoo'n geval anders vragen dan: „Wel, wanneer gaan we weer een vulkaan beklimmen?" Wat kan een vulkanoloog tegenover zóóveel brani-schopperij anders stellen dan: „Wanneer U wilt. Wij heb. ben een ruim assortiment voorradig, op Java alleen al 30 stuks. Dan o…
Van Jarongan uit loopt eer breed paardonepad war do Me. To marasowoe. Volgen wij dat pad en stokon wo hos ravijn (wontolij van Kp. Tjomarasowoe) over, dan komen wij direct na ravijn op een boschpad uit, dat ook djalan ka Kawah" genoond wordt. Large dit pad kunnon wij de Kawah bereiken.
The Papandajang, situared in the Western part of the District Cheribon, in the province of Suka-pura, was formerly one of the largest volcanoes of the Island, but the greatest part of it was swallowed up in the earth, after a short but very severe combustion in the year 1772.
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.
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.
During 1922 the G. Lamongan was often visited by the volcano guideship survey namely in April, June and August.
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.
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).
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.
