The dilemmas of risk-sensitive development on a small volcanic island [PDF]

, 2016
In the Small Islands Developing State (SIDS) of St Vincent and the Grenadines in the Caribbean, the most destructive disasters in terms of human casualties have been the multiple eruptions of La Soufrière volcano situated in the north of St Vincent ...

Origins and Alteration of Ediacaran Carbonates Recording the Shuram Excursion in Oman

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.
Abstract The Shuram excursion is the largest known negative carbon isotope excursion in Earth's history. Recognized globally, it follows the Ediacaran Gaskiers glaciation and precedes a marked increase in the diversity and complexity of the earliest macroscopic multicellular organisms in the fossil record.

Probabilistic, Multi‐Sensor Eruption Forecasting

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract We developed an eruption forecasting model using data from multiple sensors or data streams with the Bayesian network method. The model generates probabilistic forecasts that are interpretable and resilient against sensor outage. We applied the model at Whakaari/White Island, an andesite island volcano off the coast of New Zealand, using ...

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

Changes in Crater Morphology Associated With Volcanic Activity at Telica Volcano, Nicaragua

Geochemistry, Geophysics, Geosystems, 2020
Volcanic summit craters are typically noted to form by roof collapse into a depressurized magma chamber or by explosive excavation. Recent examples of effusive activity (e.g., Kilauea Volcano, Hawai'i) allowed specifically for quantification of the ...

Long-term volcanic hazard assessment on El Hierro (Canary Islands) [PDF]

, 2014
Long-term hazard assessment, one of the bastions of risk-mitigation programs, is required for land-use planning and for developing emergency plans.

First hydroacoustic recording of ebullition events in an active volcanic lake – Poás, Costa Rica

Volcanica
This study demonstrates how the sounds of subaqueous gas seeps can be used to measure the volume of volcanic gas being released into an active crater lake, weeks before an eruptive period.

Spatial and temporal distributions of b-value in and around Shinmoe-dake, Kirishima volcano, Japan

Earth, Planets and Space, 2018
Kirishima Shinmoe-dake, located in southern Kyushu, Japan, erupted in October 2017 after 6 years of quiescence. Analysis of volcanic gas indicates that magma upwelling from depth affected this eruption.

The thermal signature of Aso Volcano during unrest episodes detected from space and ground-based measurements

Earth, Planets and Space, 2018
The thermal signature of Aso Volcano (Nakadake) during unrest episodes has been analyzed by combining the MODIS-MIROVA data set (2000–2017) with high-resolution images (LANDSAT 8 OLI and Sentinel 2) and ground-based thermal observations (2013–2017).
