Broadband Waveform Modeling Over a Dense Seismic Network [PDF]

open access: yes, 2006
We developed a "two-way" calibration technique for studying clustered events, particularly their mechanisms and rupture directivities. First, we demonstrate that the magnitude 4 events with known source mechanisms can be used to calibrate the path ...

Fracture‐Mesh Faulting in the Swarm‐Like 2020 Maacama Sequence Revealed by High‐Precision Earthquake Detection, Location, and Focal Mechanisms

open access: yesGeophysical Research Letters, 2023
In August of 2020, an earthquake sequence initiated within the Maacama fault zone in northern California, raising questions about its relationship with the larger‐scale fault.

Mechanisms of Scarring in Focal Segmental Glomerulosclerosis [PDF]

open access: yesJournal of Histochemistry & Cytochemistry, 2019
Focal segmental glomerulosclerosis (FSGS) presents with scar in parts of some glomeruli and often progresses to global and diffuse glomerulosclerosis. Podocyte injury is the initial target in primary FSGS, induced by a circulating factor. Several gene variants, for example, APOL1, are associated with increased susceptibility to FSGS.

The Al Hoceima earthquake of May 26, 1994 and its aftershocks: a seismotectonic study

open access: yesAnnals of Geophysics, 1998
The present paper focuses on the moderate earthquake that occurred on May, 26, 1994, at 8 h 27 min, which caused great damage and two deaths. The epicentre of the main shock was located at 35.280N, 3.990W. The focal depth was 13 km, and the magnitude (Md)

First Focal Mechanisms of Marsquakes [PDF]

open access: yesJournal of Geophysical Research: Planets, 2021
AbstractSince February 2019, NASA's InSight lander is recording seismic signals on the planet Mars, which, for the first time, allows to observe ongoing tectonic processes with geophysical methods. A number of Marsquakes have been located in the Cerberus Fossae graben system in Elysium Planitia and further west, in the Orcus Patera depression.

Main shock and aftershocks of the December 13, 1990, Eastern Sicily earthquake

open access: yesAnnals of Geophysics, 1995
n this paper we describe the location and the fault plane solution of the December 13, 1990, Eastern Sicily earthquake (ML = 5.4), and of its aftershock sequence.

The geodynamics of Mt. Etna volcano during and after the 1984 eruption

open access: yesAnnals of Geophysics, 1999
Data concerning M > 2.5 earthquakes that occurred at Mt. Etna volcano (Sicily, Italy) during the period April 15th - October 29th, 1984 are here presented and discussed. Only those events with reliable focal mechanisms (at least eight polarities) have

The present-day stress field along the Northwest Pacific Wadati-Benioff zone constrained by focal mechanisms of moderate earthquakes

open access: yesFrontiers in Earth Science, 2023
The present-day stress field in the northwest Pacific Wadati-Benioff Zone (WBZ) has been investigated on the basis of earthquake focal mechanism catalog covering the period from 2012 to 2021. Our catalog contains 201 focal mechanism solutions (Mw 4.0–5.9)

Stress-field evolution during the 26 November 2019 Durrës (Albania) earthquake sequence: Co-seismic, early post-seismic, and tectonic-region inversions [PDF]

open access: yesEPJ Web of Conferences
We resolve the stress field associated with the 26 November 2019 Mw 6.3 Durrës earthquake sequence through three windows: the co-seismic mainshock, the early post-seismic phase (mainshock plus the 36 largest aftershocks recorded between 26 November and 2

Seismic Sequence Analysis of the Arraiolos Zone, South Portugal, and Its Seismotectonic Implications: A Detailed Analysis of the Period 15 January–30 June 2018

open access: yesRemote Sensing, 2023
The Arraiolos Zone has been affected by the persistent superficial seismicity (focal depth < 20 km) of a weak magnitude (M < 4) and some events of a higher magnitude (M > 4), and is mainly located around the Aldeia da Serra village.
