Solar Eruptive Events: Coronal Dimming and a New CubeSat Mission [PDF]
, 2016 Coronal mass ejections (CMEs) and solar flares are among the most energetic events in the solar system. As such, they power numerous physical processes in environments that push the limits of theory, observation, data analysis, and laboratory experiments.

Relativistic Signatures of Flux Eruption Events near Black Holes
Galaxies, 2022 Images of supermassive black holes produced using very long baseline interferometry provide a pathway to directly observing effects of a highly curved spacetime, such as a bright “photon ring” that arises from strongly lensed emission. In addition, the emission near supermassive black holes is highly variable, with bright high-energy flares regularly ...

Frontiers in Earth Science, 2022 Open conduit volcanoes like Stromboli can display elusive changes in activity before major eruptive events. Starting on December 2020, Stromboli volcano displayed an increasing eruptive activity, that on 19 May 2021 led to a crater-rim collapse, with ...

Cascading events during the 1650 tsunamigenic eruption of Kolumbo volcano
Nature Communications, 2023 AbstractVolcanic eruptions can trigger tsunamis, which may cause significant damage to coastal communities and infrastructure. Tsunami generation during volcanic eruptions is complex and often due to a combination of processes. The 1650 eruption of the Kolumbo submarine volcano triggered a tsunami causing major destruction on surrounding islands in the

One hundred lava flows of Mt. Etna, Italy: July 2019–December 2023 update
Journal of MapsIntegration of multi-sensor, multi-platform remotely sensed data is an effective methodology for monitoring active volcanoes as it ensures a constant data flow, which is needed for repeated eruptive events in brief intervals.

Volcanica, 2018 After eight years of quiescence, Fernandina volcano experienced two short-lived eruptions, on 4 September 2017 and 16 June 2018. The eruptions were characterized by very short periods of unrest that started a few hours before the initiation of the ...

The 2010 explosive eruption of Java's Merapi volcano—A ‘100-year’ event [PDF]
Journal of Volcanology and Geothermal Research, 2012 Merapi volcano (Indonesia) is one of the most active and hazardous volcanoes in the world. It is known for frequent small to moderate eruptions, pyroclastic flows produced by lava dome collapse, and the large population settled on and around the flanks of the volcano that is at risk.

Remote Sensing, 2022 This paper reconstructs, for the first time, the motion dynamics of an eruptive cloud formed during the catastrophic eruption of the Sheveluch volcano in November 1964 (Volcanic Explosivity Index 4+).

Evolution of Conduit Geometry and Eruptive Parameters During Effusive Events [PDF]
Geophysical Research Letters, 2018 AbstractThe dynamics of effusive events is controlled by the interplay between conduit geometry and source conditions. Dyke‐like geometries have been traditionally assumed for describing conduits during effusive eruptions, but their depth‐dependent and temporal modifications are largely unknown. We present a novel model which describes the evolution of
