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 …
L' Objet de cette these a ete de developper une chaine de mesures geree, par micro-ordinateur, specialement adaptee au releve automatique volcanique, et de tester la faisabilite technologique et methodologique de la surveillance de ces courants.
A seismicity studies has been done on Guntur Volcano using seismic data record from Januari 2013 to March 2013. Spectrum analysis and hypocenter analysis method were used in this study. Spectrum analysis was used to determine the domain frequency, and hypocenter analysis was used to know the depth of earthquake source. Telah dilakukan penelitian seismisitas Gunung Guntur dengan data bulan Ja…
