Volume changes at Santiaguito volcano between 2011 and 2019 based on TanDEM-X InSAR data

Frontiers in Earth Science
The Santiaguito volcanic dome complex in Guatemala consists of four volcanic domes formed within the 1902 eruption crater of Santa María volcano, with only the oldest dome, Caliente, currently active.

Seismic mode «drumbeats»: promoting and supporting eruption of andesitic and dacitic volcanoes and their features (overview)

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2019
During extrusive eruptions of andesitic and dacitic volcanoes, in some cases, squeezing of viscous lava was accompanied by the occurrence of «drumbeats» earthquakes.

Field trip to the Ischia resurgent caldera, a journey across an active volcano in the Gulf of Naples [PDF]

, 2018
Ischia is one of the most impressive examples of post-caldera resurgence in the world, with its almost 1,000 m of uplift in less than 30 ka. This three-days field trip will lead the participants through the geological and volcanological history of the ...

Emplacement Scenarios for Volcanic Domes on Venus [PDF]

, 2012
One key to understanding the history of resurfacing on Venus is better constraints on the emplacement timescales for the range of volcanic features visible on the surface.

The geology of the Venera/Vega landing sites [PDF]

We have performed a photogeological analysis of the Venera Vega landing sites using Magellan radar images. These seven sites are the only places on Venus where geochemistry measurements were taken.

The origin of channels and associated deposits in the Elysium region of Mars [PDF]

Photogeological studies of the Elysium volcanic province of Mars show that its sinuous channels are part of a large deposit which probably was emplaced as a series of huge volcanic debris flows or lahars.

Lunar Mare Lava Flow Dynamics and Emplacement: Predictions of Non-Newtonian Flow Dynamics, Syn- and Post-emplacement Cooling and Volatile Release Patterns, and Vertical and Lateral Flow Structure Development

The Planetary Science Journal
We apply basic principles of magma ascent from deep source regions and its eruption into a low-gravity vacuum environment to develop a theoretical treatment of the fluid dynamics and thermodynamics of mare basalt lava flow emplacement and evolution on ...

Venus steep-sided domes: Relationships between geological associations and possible petrogenetic models [PDF]

Venus domes are characterized by steep sides, a circular shape, and a relatively flat summit area. In addition, they are orders of magnitude larger in volume and have a lower height/diameter ratio than terrestrial silicic lava domes.
