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 ...

Here, we use heterochronous genomic data from samples obtained before and immediately after the 2011 eruption of the Puyehue-Cordn Caulle volcanic complex in Patagonia to explore the genetic impacts of this event on two parapatric species of rodents, the colonial tuco-tuco (Ctenomys sociabilis) ...
Unlike some volcanic events at known hot spots,the volcano provided little hint that it was ready for an eruption,making it difficult for officials to warn visitors that the destructive event was about to occur. As CNN reports a group of 23 visitors was near the volcano s...
