The build-up and triggers of volcanic eruptions
More than 800 million people live in proximity to active volcanoes and could be directly
impacted by potential eruptions. Mitigation of future volcanic hazards requires adequate …

Extreme curvature of shallow magma pathways controlled by competing stresses: Insights from the 2018 Sierra Negra eruption
Eruptions at shield volcanoes often occur from radially aligned linear fissures fed by blade‐
like magma‐filled cracks (dykes). The fissures of the 2018 Sierra Negra eruption were …

Mechanical modeling of pre‐eruptive magma propagation scenarios at calderas
Simulating magma propagation pathways requires both a well‐calibrated model for the
stress state of the volcano and models for dike advance within such a stress field. Here, we …

Giant dikes and dike-induced seismicity in a weak crust underneath Cerberus Fossae, Mars
Cerberus Fossae is a long and narrow graben system located approximately 1000 km
southeast of Elysium Mons, Mars. These structures have long been thought to be dike …

On the propagation path of magma‐filled dikes and hydrofractures: The competition between external stress, internal pressure, and crack length
Mixed‐mode fluid‐filled cracks represent a common means of fluid transport within the
Earth's crust. They often show complex propagation paths which may be due to interaction …

Quantifying dyke-induced graben and dyke structure using 3D seismic reflection data and the role of interpretation bias
During dyke intrusion, tensile stresses concentrated within the overlying rock may lead to the
formation of normal faults. These faults typically form graben-bounding pairs that are sub …

Field evidence for the lateral emplacement of igneous dykes: Implications for 3D mechanical models and the plumbing beneath fissure eruptions
Seismological and geodetic data from modern volcanic systems strongly suggest that
magma can be transported significant distance (tens of kilometres) in the subsurface away …

Ascent rates of 3-D fractures driven by a finite batch of buoyant fluid
Propagation of fluid-filled fractures by fluid buoyancy is important in a variety of settings, from
magmatic dykes and veins to water-filled crevasses in glaciers. Industrial hydro-fracturing …

The roles of elastic properties, magmatic pressure, and tectonic stress in saucer‐shaped sill growth
SPA Gill, RJ Walker - Journal of Geophysical Research: Solid …, 2020 - Wiley Online Library
Near‐surface igneous sills commonly exhibit saucer‐like shapes, formed due to interaction
with the Earth's surface once some critical sill length is reached relative to its depth. Sill …
