Fracturing and tectonic stress drive ultrarapid magma flow into dikes
Many examples of exposed giant dike swarms can be found where lateral magma flow has
exceeded hundreds of kilometers. We show that massive magma flow into dikes can be …

Evolving shallow conduit revealed by tremor and vent activity observations during episodic lava fountaining of the 2021 Geldingadalir eruption, Iceland
Cyclic behaviour is observed in volcanic phenomena ranging from caldera collapses to
explosions, spattering or lava fountaining. The repeating processes can define irregular …

Satellite radar and camera time series reveal transition from aligned to distributed crater arrangement during the 2021 eruption of Cumbre Vieja, La Palma (Spain)
Magma-filled dikes may feed erupting fissures that lead to alignments of craters developing
at the surface, yet the details of activity and migrating eruptions at the crater row are difficult …

Constraining spatiotemporal characteristics of magma migration at Piton de la Fournaise volcano from pre‐eruptive seismicity
Z Duputel, O Lengliné… - Geophysical Research …, 2019 - Wiley Online Library
Volcano‐tectonic seismicity has been recorded for decades on various volcanoes and is
linked with the magma transport and reservoir pressurization. Yet earthquakes often appear …
