Determining the stress field in active volcanoes using focal mechanisms
Stress inversion of seismological datasets became an essential tool to retrieve the stress field of active tectonics and volcanic areas. In particular, in volcanic areas, it is able to put constrains on volcano-tectonics and in general in a better ...

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

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.

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

An earthquake focal mechanism catalog for source and tectonic studies in Mexico from February 1928 to July 2022 [PDF]
We present a focal mechanism catalog for earthquakes that occurred in Mexico and surrounding areas reported from February 1928 to July 2022. The magnitude of the events varies from −0.9 to 8.2.

A detailed analysis of some local earthquakes at Somma-Vesuvius
In this paper, we analyze local earthquakes which occurred at Somma-Vesuvius during two episodes of intense seismic swarms, in 1989 and 1995 respectively.

TECTONOPHYSICAL ZONING OF THE TIEN SHAN ACTIVE FAULTS – DETERMINISTIC STRONG EARTHQUAKE PREDICTION
The January 23, 2024 М7.0 Wushi earthquake (China) put an end to the period of strong earthquake quiescence that had lasted for about 33 years in the Tien Shan. The risk of occurrence of new strong earthquakes in the coming years has been discussed among

Volcano-tectonic processes in the central part of Iceland, covered by the Vatnajökull glacier, are investigated by inversion of focal mechanisms. Working on a large catalogue of focal mechanisms determined by the Icelandic Meteorological Office, we used ...
