The 2021 Fagradalsfjall eruption in the Reykjanes peninsula, Iceland, was marked by episodes with varying volcanic activity. Our study focuses on the period from eruption start on the 19th March 2021 until the 2nd May 2021. This phase was marked by r

Bathymetric highs resist subduction producing large- to small-scale change in the morphology of the subduction zone: Increase of the outer-rise curvature, trench indentation and large-scale slides and slumps in the fore-arc region. At the plate inter

In the past decade, the use of fiber optic cables to sense ground motion (Distributed Acoustic Sensing-DAS) has become a topic of great interest in seismology because of its wide sensitivity range, dense spatial sampling and new deployment possibilit

The resistance of bathymetric highs to subduction results in large-scale morphological distortions of the outer-rise, trench, and fore-arc regions. Once subducted, bathymetric highs induce frictional segmentation along the plate interface that may re

In this study, we present a new approach based on recent advances in deep learning for rapid source-parameter estimation of microseismic earthquakes. The seismic inversion is represented in compact form by two convolutional neural networks, with indi

The determination of seismic moment tensors (MTs) for microseismicity poses challenges because of both the large number of events that are typically recorded, and their low signal to noise ratio. In recent years, automated moment tensor inversion met

Despite advanced seismological methods, source characterization for micro-seismic events remains challenging since current inversion and modelling of high-frequency waveforms are complex and time consuming. For a real-time application like induced-se

Sierra Negra is a basaltic shield volcano in the Galapagos Archipelago (Ecuador) and is the largest of the Galapagos volcanoes. The 2018 eruption was a complex event that included eruptive fissures opening on the northern rim and north-western flank.
