New Volcanic Revelations May Help Predict When Eruptions Will Occur
2014-05-05 09:10:30

[ Watch the Video: New Insight May Help Predict Volcanic Eruption Behavior ] Gerard LeBlond for redorbit.com - Your Universe Online Volcanologists from the University of Liverpool have discovered how lava dome volcanoes erupt. This could help develop methods on predicting how volcanoes will act. The process of frictional melting determines how the volcano will erupt. The speed of the lava rise and how much friction it creates is determined by this process. Within the lava dome the...

Origins On The Behavior Of Hawaiian Volcanoes
2014-05-01 03:05:10

University of Hawaii ‑ SOEST Kīlauea volcano, on the Big Island of Hawai'i, typically has effusive eruptions, wherein magma flows to create ropy pāhoehoe lava, for example. However, Kīlauea less frequently erupts more violently, showering scoria and blocks over much of the surface of the island. To explain the variability in Kīlauea's eruption styles, a team including Bruce Houghton, the Gordon Macdonald Professor of Volcanology in Geology and Geophysics at the University of Hawai'i...

[ Watch the Video: Dormant Volcanoes Can Quickly Become Active ] Lawrence LeBlond for redOrbit.com - Your Universe Online New research by UC Davis and Oregon State University may soon lead to new forecasts into how soon volcanoes are ready to erupt. Geologists from both schools, publishing a paper online in the journal Nature, have found that in order for an eruption to occur, molten rock under the volcano must be sufficiently mobile. The evidence comes from a study of Oregon’s...
