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.

Recurrent patterns in fluid geochemistry data prior to phreatic eruptions

, 2016
Not all volcanic eruptions are magma-driven: the sudden evaporation and expansion of heated groundwater may cause phreatic eruptions, where the magma involvement is absent or negligible. Active crater lakes top some of the volcanoes prone to phreatic activity.

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
