A numerical model for precursory time sequences of the phreatic eruptions of Mt. Ontake, central Japan

Earth, Planets and Space
The 2014 phreatic eruption of Mt. Ontake was preceded by increased volcano-tectonic (VT) seismicity, but all other types of precursors were obscure. A subsurface process leading to eruption with few precursors has yet to be identified.

Decrypting the sediment record of very late stage volcanic activities in Tatun volcano group, Northern Taiwan: evidence from ashy deposits

Terrestrial, Atmospheric and Oceanic Sciences
The Tatun Volcano Group (TVG) is an active volcano on Taiwan and poses a potential threat to public safety in northern Taiwan. Currently, the youngest eruption records among the TVG occurred around Mt. Chihsing in the late Pleistocene.

MAARS OF SOUTH-CENTRAL OREGON By [PDF]

If we could go back in time some 5 to 10 million years to the Pliocene Epoch and recreate the landscape of south-central Oregon, here are some of the things we would probably see: From a plain originally of slight relief, faulting has already ...

Geochemical evaluation for the fumarolic gases collected at Ojigokudani, Iwate volcano, Japan in September 2024

Earth, Planets and Space
Anomalous earthquakes and crustal movements have been observed at Iwate volcano in northern Honshu, Japan, where phreatic eruptions have been feared since February 2024, and the volcanic alert level was raised from 1 to 2 on October 2, 2024. We collected
