Merapi volcano, located at Central Java - Indonesia, is one of the most active volcano in the world. Since 1006, about 60 cycle of activity were reported. During the 100 years, more than 24 activities recorded in detail. Dome formation and pyroclastic flow have been occurred in turns.
Condensates, silica tube sublimates and incrustations were sampled from high temperature fumaroles (500 - 800°C) and lava sample were collected at Merapi Volcano, Indonesia in Jan - Feb. 1984).
Mass and energy balance allow magma transport within volcanoes to be quantified. Thus work used microgravity and height data and their variation to interpret volcanic. activity. An international comparison of absolute and relative gravimeters (at BIPM, serves) and a set of measurements in a adjustable pressure-temperature chamber revealed the performances and the limits of the Scintrex SG3-M me…
Mount Merapi, island are volcano located in the center of Java (Indonesia), lies upon the remnents of a volcano older than 400.000 years called Pre-Merapi. Sensu stricto Merapi is a very young volcano characterised by a rapid edification. Its history is divided into four periods (ancient, Middle aged, Recent and Historical Merapi).
Merapi volcano is one of the most active volcanoes in the world and during the last 3000 yrs, it has been more or less continuously in eruption. Merapi volcano is a stratovolcano with a south-west facing horseshoe-shaped summit crater filled by a lava dome. Its composition rangers from basalt to basaltic andesite (52 to 56% SiO2) and it has high Al2O3 (18.5 to 20.2% wt) and medium to high K2O …
