Outflow channels of the Tharsis province on Mars testify to the drainage of groundwater reservoirs through magmatic and tectonic processes. The Olympica – Jovis Fossae system extends over 500 km, but the significance of its deep and narrow channels

Inferences about sheet intrusion emplacement mechanisms have been built largely on field observations of intrusion tip zones: magmatic systems that did not grow beyond their observed state. Here we use finite element simulation of elliptical to super

Lahars impose significant secondary hazards on highly populated volcanic islands by remobilizing volcanic ash deposits. Karthala, on Grande Comore Island, is a relatively young and poorly eroded basaltic shield volcano with sporadic occurrence of ash

Magma intrusions grow to their final geometries by deforming the Earth's crust internally and by displacing the Earth's surface. Interpreting the related displacements in terms of intrusion geometry is key to forecasting a volcanic eruption. While sc

Floors of impact craters on rocky planetary bodies in our Solar System are often fractured and bulged. Such deformation features are thought to form by the ascent of impact-generated magma and the inflation of laccolith-shaped magma bodies at a shall

High-viscosity magma can form laccolith intrusions that deform and fracture the overburden, causing surface uplift and ground fracturing. Laccolith-induced deformation features have been described at well-exposed outcrops of long-solidified intrusion

Many volcanoes exhibit evidence of long-term deformation driven by gravity. This deformation influences the development of magmatic plumbing systems and volcanic vent locations, and it manifests as earthquakes and ground surface motions. Two end-memb

Surface deformation patterns on terrestrial planetary bodies have been interpreted as magma emplacement features due to their similarity with Earth analogues or their association with inferred eruptive products. Dome-shaped surface uplift features we

For decades scaled analog experiments have improved the understanding of a broad range of multiphase volcanological processes in controlled laboratory environments. Successfully modeled processes include magma flow through magma reservoirs, conduits

When magma ascends through the shallow parts of terrestrial planetary crust, it deforms the surrounding host rocks. The deformation patterns observed at the surface offer indirect means to characterize the position, geometry and volume of subsurface
