Control of gravitational potentialenergy on the distribution of off‐riftvolcanic activity in the Turkanadepression, East African rift

(a) Faults, seismicity, and Pleistocene-Holocene volcanic vents in the Turkana Depression superimposed on a SRTM (Nasa Shuttle Radar Topography Mission) digital elevation model. Seismicity is from U.S. Geological Survey National Earthquake Information Center catalog (1900 to present; citation needed for the NEIC catalog, https://earthquake.usgs.gov/earthquakes/search/).

Subsurface mechanical architecture of coronae on Venus and its implications for processes governing fractures and seismicity

Figure 2 The investigated coronae are all shown on the global Magellan synthetic aperture radar left-look mosaic base map: Atahensik (panels a–c), Demeter (panels d–f), Didilia (panels g–i), Heng-O (panels j–l), Kamui-Huci (panels m–o), Ninkarraka (panels p–r), Pavlova (panels s–u). Magellan global topography (4641 m/px) is displayed in panels b,e,h,k,n,q,t. The…

Uncertainty quantification in volcanology: observations, numerical modelling, and hazard/risk assessment: preface to the special issue

Figure 1 a) Simplified scheme showing the main volcanic phenomena that can be observed during and/or before and/or after a volcanic eruption, including related secondary effects such as water-sediment flows (e.g., lahars), tsunamis or fires. b) Conceptual diagram showing the interconnected fields where uncertainty is present and how it can…

The Kolumbo Volcanic Field, Greece: expert elicitation findings supporting volcanic hazard and risk assessment

Event tree framework showing elicitation questions related to a future eruption of the Kolumbo Central Volcano. A yellow box contains the questions related to gas density currents, a red box to pyroclastic density currents (PDC), a gray box to ash fallout, and a blue box to major tsunamis. Questions in…
