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.

Pilot application of the Volcanic Unrest Index (VUI) for active volcanoes in Japan: Mount Tokachidake and Mount Meakandake

Earth, Planets and Space
The quantitative assessment of volcanic unrest is essential for understanding volcanic processes and supporting decision-making. However, systematic approaches to evaluating unrest episodes remain underdeveloped, particularly during non-eruptive periods.

Products of an effusive subglacial rhyolite eruption: Blahnukur, Torfajokull, Iceland. [PDF]

, 2001
. We present field observations from Blahnukur, a small volume (400 m thick. Lithofacies associations attest to complex patterns of volcano-ice interaction.

Dynamics and hazard of phreatic eruptions

Phreatic events may represent precursors of magmatic eruptions, but they can also occur as single or multiple episodes punctuating the activity of volcanoes characterised by active hydrothermal systems. The Breccia De Fiore deposit represents evidence of the phreatic activity preceding by fifteen years the onset of the 1888–1890 magmatic eruption at La

Eruption dynamics and triggering of phreatic eruptions at the Rerewhakaaitu Fissures, New Zealand

Phreatic eruptions are a form of steam-driven eruptions are violent explosions of steam, water, and rock caused by the decompression of superheated fluids and gasses.
