Prevalence of Seismic Rate Anomalies Preceding Volcanic Eruptions in Alaska
Frontiers in Earth Science, 2018 Seismic rate increases often precede eruptions at volcanoes worldwide. However, many eruptions occur without such precursors. Additionally, identifying seismic rate increases near volcanoes with high levels of background seismicity is non-trivial and ...

Optimization of Network-Based Earthquake Early Warning Systems on the Korean Peninsula
IEEE Access, 2022 Most countries and local governments provide earthquake services in the public domain, and they must have high accuracy. If a missed alarm of the Earthquake Early Warning (EEW) system causes many casualties, or if the industrial system is temporarily ...

Magma chamber decompression during explosive caldera-forming eruption of Aira caldera
Communications Earth & Environment, 2021 Substantial magma chamber decompression during the early plinian stage of the eruption of Aira volcano, Japan, 30,000 years ago caused intense ground deformation and caldera collapse, according to analyses of water content in quartz ...

Atmosphere, 2021 Vulcanian eruptions (short-lived explosions consisting of a rising thermal) occur daily in volcanoes around the world. Such small-scale eruptions represent a challenge in numerical modeling due to local-scale effects, such as the volcano’s topography ...

Seismo-Acoustic Characterization of Mount Cleveland Volcano Explosions
Frontiers in Earth Science, 2020 Volcanic explosions can produce large, ash-rich plumes that pose great hazard to aviation, yet may often have few precursory geophysical signals. Mount Cleveland is one of the most active volcanoes in the Aleutian Arc, Alaska (United States) with at ...
