Seismic imaging and petrology explain highly explosive eruptions of Merapi Volcano, Indonesia

Study of 2010 Eruption of Merapi Volcano, Indonesia Using Alos Palsar Interferometry

Mount Merapi is one of the most active volcanoes in Indonesia, and its most recent massive eruption was in November 2010, causing great loss of lives and assets. Land movement of the volcano and the regions around were known to be significant. One of the methods that can be used to monitor such motion is Interferometric Synthetic Aperture Radar (InSAR). The Synthetic Aperture Radar (SAR) images...

Evidence for Recent Large Magnitude Explosive Eruptions at Damavand Volcano, Iran with Implications for Volcanic Hazards

Damavand is a large dormant stratovolcano in the Alborz Mountains of northern Iran located in one of the most populous provinces, which could be adversely affected by tephra fall from Damavand. The youngest known eruption is a lava flow on the western flanks with an age of 7.3 ka. The volcanic products are predominantly porphyritic trachyandesite. Three major young pumice deposits, named here a...

Magma decompression rates during explosive eruptions of Kīlauea volcano, Hawaii, recorded by melt embayments

The decompression rate of magma as it ascends during volcanic eruptions is an important but poorly constrained parameter that controls many of the processes that influence eruptive behavior. In this study, we quantify decompression rates for basaltic magmas using volatile diffusion in olivine-hosted melt tubes (embayments) for three contrasting eruptions of Kīlauea volcano, Hawaii. Incomplete e...
