Kilauea lava fuels phytoplankton bloom Hawaii Island
2019/10/18
The 2018 Kilauea volcano eruption injected millions of cubic feet of molten lava into nutrient-poor waters off the Big Island of Hawaii. The lava-impacted seawater contained high concentrations of nut...
Taking advantage of a rare orbital alignment between two of Jupiter’s moons, Io and Europa, researchers have obtained an exceptionally detailed map of the largest lava lake on Io, the most volcanicall...
Formation processes of the 1909 Tarumai and the 1944 Usu lava domesin Hokkaido,Japan
lava domes Tarumai volcano Usu volcano squeeze of magma growth rate of domes Hagen-Poiseuille's Law
2015/9/11
The formation of the two particular lava domes in Hokkaido, Japan is described and interpreted mainly from geophysical viewpoints. The 1909 eruption of Tarumai volcano was not violent but produced a l...

2015/8/27
Data of the flank eruptions of Etna from over the last 400 years were extracted from the new geological map for the lava flow extensions and vent positions, and from the catalogs of historical eruptio...
Cooling of a channeled lava flow with non-Newtonian rheology: crust formation and surface radiance
Rheology Magmas Thermodynamics Lava flow Effusion rate
2015/8/27
We present here the results from dynamical and thermal models that describe a channeled lava flow as it cools by radiation. In particular, the effects of power-law rheology and of the presence of bend...
