A comparison of seasonal rainfall forecasts over Central America using dynamic and hybrid approaches from Copernicus Climate Change Service seasonal forecasting system and the North American Multimodel Ensemble. [PDF]

Int J Climatol, 2023
Dynamic, statistical, and hybrid approaches can be used to forecast seasonal rainfall. We compare approaches by evaluating how dynamic and hybrid forecasts from C3S and NMME perform relative to statistical predictions over Central America during key wet season months. Results reveal high forecast skill over the North Pacific and relatively low skill in

Structural Evolution of a Crustal-Scale Seismogenic Fault in a Magmatic Arc: The Bolfin Fault Zone (Atacama Fault System). [PDF]

Tectonics, 2021
Abstract How major crustal‐scale seismogenic faults nucleate and evolve in crystalline basements represents a long‐standing, but poorly understood, issue in structural geology and fault mechanics. Here, we address the spatio‐temporal evolution of the Bolfin Fault Zone (BFZ), a >40‐km‐long exhumed seismogenic splay fault of the 1000‐km‐long strike‐slip ...

Volcano observatories and monitoring activities in Guatemala

Volcanica, 2021
The tectonic and volcanic environment in Guatemala is large and complex. Three major tectonic plates constantly interacting with each other, and a volcanic arc that extends from east to west in the southern part of the country, demand special attention ...

Crustal Structure Across the Northern Region of the Islas Marías Archipelago

Frontiers in Earth Science, 2021
The tectonic interaction between the Rivera and North American plates north of the Bahía de Banderas is poorly understood. The nature of the crust and where the subduction ends in the western part of the Islas Marias Archipelago are still controversial ...

The TsuJal Amphibious Seismic Network: A Passive-Source Seismic Experiment in Western Mexico

Frontiers in Earth Science, 2021
The geodynamic complexity in the western Mexican margin is controlled by the multiple interactions between the Rivera, Pacific, Cocos, and North American plates, as evidenced by a high seismicity rate, most of whose hypocenters are poorly located.

Joint Inversion of Geodetic and Strong Motion Data for the 2012, Mw 6.1–6.0, May 20th and May 29th, Northern Italy Earthquakes: Source Models and Seismotectonic Interpretation

Journal of Geophysical Research: Solid Earth, Volume 128, Issue 5, May 2023., 2023
Abstract We present the first rupture models of the two mainshocks of the 2012 northern Italy sequence, determined by jointly inverting seismic and geodetic data. We aim at providing new insights into the mainshocks for which contrasting seismotectonic interpretations are proposed in literature. Sources' geometric parameters were constrained by seismic

Deposit‐Derived Block‐and‐Ash Flows: The Hazard Posed by Perched Temporary Tephra Accumulations on Volcanoes; 2018 Fuego Disaster, Guatemala

Journal of Geophysical Research: Solid Earth, Volume 127, Issue 6, June 2022., 2022
Abstract The impact of hazardous pyroclastic density currents (PDCs) increases with runout distance, which is strongly influenced by the mass flux. This article shows that the mass flux of a PDC may derive not only from vent discharge during the eruption, but also from partly hot, temporary stores (accumulations) of aerated pyroclastic material perched

Pre‐ and Co‐Eruptive Analysis of the September 2021 Eruption at Cumbre Vieja Volcano (La Palma, Canary Islands) Through DInSAR Measurements and Analytical Modeling

Geophysical Research Letters, Volume 49, Issue 7, 16 April 2022., 2022
Abstract We investigate the 19 September 2021 eruption of the Cumbre Vieja volcano (La Palma, Canary Islands, Spain). In particular, we analyze the Differential Interferometric Synthetic Aperture Radar (DInSAR) measurements obtained by processing Sentinel‐1 images acquired from both ascending and descending orbits.
