For the post-World War II period, most of the data are derived from observations by the then Volcanological Survey Division of the Geological Survey of Indonesia, where one of us (I.S) was attached since 1952.
Volcanic disaster and mitigation concern sany institution and its aspects with five principal elements and play such as) role volcanic crisis 1. Source of the crisis it self(the volcano) 2. Team of the Scientiste who study it 3. The administrative authorities 4. The Media 5. The population who live near by. In Indonesia the five elements of risk are coordinated by the government under sin…
The Quaternary volcanic rocks of Wilis Mountains can be divided into three morphocets : i.e the Jeding - Patukbanteng Morphocet, the Pawonsewu Morphocet, and the Argokalangan Morphocet. A sub-division of a morphocet is called a "morphonits", and eight morphonits have been recognized.
This is the sixth report on the progress of the project Volcano Monitoring and Research in Indonesia, covering the first quarter of 1987. Background information on the project and the organizational status of the Volcanological Survey of Indonesia (VSI) and the U.S. Geological Survey (USGS) were reported in an earlier report (Casadevall, 1985).
Mount Lamongan 1670 m above sea level is located in the regencies of lumajang and Probolinggo, Fast Java.

This volcano is surrounded by other two big volcanoes, they are Mount Iyang Argopuro on the East and Mount Tengger-Bromo on th…
The summit crater of Mt. Kelut, an andesitic volcano in East Java Indonesia, normally contains a lake with surface temperatures varying from 31 to 36 centigrade around inlet.
The The geophysical investigations of Mt. Kelud began to apply in 1978, initially with emphasis on geomagnetic survey. instrument used was the 595 Type Elsec Magnetometer with an accuracy of 18.
This Volcano is known as very dengerous, because its eruptions always caused victims and destroyed of arable land. The origin of the disaster because its has a crater lake on its summit, which is in ejected during each eruption.
Since the end of the 1982 - 1983 eruption of Galunggung volcano, west Java, a large and growing lake has formed within the 1982 - 1983 crater. The volume of this lake in July 1986 is approximately 6.1 million cubic meters of water. This water is accumulating at a rate of approximately 2.6 million cubic meters per year.
The continuous eruptions of Mt. Galunggung will create problems for the inhabitants in the disaster area and its surroundings, mostly in West Java. From the perspective of development, each disaster, particularly the Galunggung disaster, is a constraint to development. Above all, disasters destroy the "results of development", using up large amounts of manpower, expertise and funds.
