Earthquakes in Northern Eurasia, 2019 The results of near real-time monitoring of the active Kamchatka volcanoes are described. Continuous monitoring was carried out using three remote methods: 1) seismic monitoring according to automatic telemetric seismic stations; 2) visual and video observation; 3) satellite observation of the thermal anomalies and the ash clouds.

Seismic characterization of pyroclastic flow activity at Soufrier Hills Volcano, Montserrat, 8 January 2007 [PDF]
, 2007 A partial dome collapse with concurrent pyroclastic flow (PF) activity occurred at Soufrière Hills Volcano (SHV), Montserrat on 8 January 2007. Pyroclastic density currents were observed to propagate from the Northwest and West sectors of the summit dome

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 ...

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 ...

Coupled subdaily and multiweek cycles during the lava dome erupt of Soufriere Hills Volcano, Montserrat [PDF]
, 2013 Observations of volcanoes extruding andesitic lava to produce lava domes often reveal cyclic behaviour. At Soufriere Hills Volcano, Montserrat, cycles with sub-daily and multi-week periods have been recognised on many occasions.

Volcanic Thunder From Explosive Eruptions at Bogoslof Volcano, Alaska
Geophysical Research Letters, 2018 Lightning often occurs during ash‐producing eruptive activity, and its detection is now being used in volcano monitoring for rapid alerts. We report on infrasonic and sonic recordings of the related, but previously undocumented, phenomenon of volcanic ...

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 ...

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 ...
