We have analyzed volcanic tremors occurred during 1986 Izu-Oshima eruption using recently digitized data. The results present a clear link between eruption styles, waveform variations and source locations of the tremors. Moreover, precursory activity of the tremors that indicates injection of magma ...

Which kind of magma produces a quiet volcanic eruption? What are the two types of tectonic plates? What is a type of magma containing little silica? What are the two types of Earth's crust? What is the main difference between lava and magma?
Two-phase flows play a central role in current scenarios of volcanic eruptions. First, the de-pressurization in the chimney connecting the magma chamber to the volcano crater allows bubble nucleation to be triggered in the liquid magma resulting in the formation of a bubbly regime whose lower ...
From there, travel to theOwakudani volcanic area, created during the last eruption of Mount Hakone some 3000 years ago. Today, much of the area is an active volcanic zone with sulfurous fumes, hot springs and hot rivers. Due to volcanic gases, the hiking trails around Owakudani are currently...

a major question. These young crater-counting ages, however, have not been confirmed by radioisotopic ages. The actual end of mare volcanism has not yet been constrained by radioisotopic dating owing to the lack of available samples from these younger volcanic units, which have incurred fewer ...
The late Cretaceous–Holocene Central European Volcanic Province (CEVP; Fig.1, Table1) is part of the Circum-Mediterranean Anorogenic Cenozoic Igneous province (CiMACI; Lustrino and Wilson2007) and comprises several volcanic regions in eastern France, western, central, and southern Germany, western ...
6 and No. 7 in a volcanic tuff bed that has undergone post-depositional alteration (Wang et al., 2020). The fossil plants preserved therein represent a swamp forest buried in situ by a single volcanic eruption (Wang et al., 2012), as evidenced by numerous erect stumps and fallen trees ...
