A significant water reservoir discovered beneath the ocean floor near New Zealand may offer insights into the mechanics of slow slip earthquakes and tectonic activity. Researchers have discovered a sea’s worth of water locked within the sediment and rock of a lost volcanic plateau that’s now...
Repeating earthquakes, or repeaters, are defined as earthquakes with overlapping rupture areas, sharing a similar location, magnitude and focal mechanism1,2,3. Due to the similarity of their sources, they generally produce highly similar waveforms1,2,3,4,5,6,7. Indeed, while a robust identifica...
The proposed models satisfactorily reproduce the magnitude–depth distribution of the swarm (October 5, 2019), preceding the two strongest earthquakes recorded in 35 years at the caldera (3.1 and 3.3—on December 6, 2019, and April 26, 2020, respectively) using hot‐water injection ...
Understanding the mechanics of such volcanic earthquakes is important to elucidate eruptive processes and to assess related hazards. This, however, is a challenging goal because of the co-involvement of multiphase (gas/liquid/solid) thermal effects, large changes in physical properties (strength, visco...
dramatically increase rock plasticity, which is essential for plate tectonics — a process that shapes the continents and oceans, and drives earthquakes and volcanism. But despite its huge importance for the evolution of rocky planets like ours, we don’t know where the Earth’s water originated....
International Symposium on In-Situ Rock Stress: International Society for Rock Mechanics; 2010.Xu, S.S., Nieto-Samaniego, A.F., Alaniz-Alvarez, S.A., 2010. 3D Mohr Diagram to Explain Reactivation of Pre-existing Planes Due to Changes in Applied Stresses. Rock Stress and Earthquakes. Taylor...
Time delays associated with processes leading to a failure or stress relaxation in materials and earthquakes are studied in terms of continuum damage mechanics. Damage mechanics is a quasi-empirical approach that describes inelastic irreversible phenomena in the deformation of solids. When a rock sample...
