Global volcanic earthquake swarm database and preliminary analysis of volcanic earthquake swarm duration

Annals of Geophysics, 1996
Global data from 1979 to 1989 pertaining to volcanic earthquake swarms have been compiled into a custom-designed relational database. The database is composed of three sections: 1) a section containing general information on volcanoes, 2) a section ...

Revealing 60 Years of Earthquake Swarms in the Southern Red Sea, Afar and the Gulf of Aden

Frontiers in Earth Science, 2021
Earthquake swarms occur sporadically at divergent plate boundaries but their recurrence over multiple decades and relation to magmatic spreading activity remain poorly understood. Here we study more than 100 earthquake swarms over a 60-year period in the

The Wakayama earthquake swarm in Japan

Earth, Planets and Space, 2023
An earthquake swarm in the Wakayama prefecture, Japan, is known as the most active and persistent swarm, with > 95,000 earthquakes (M ≥ –1.3) occurring during the 2003–2020 period.

Updip Fluid Flow in the Crust of the Northeastern Noto Peninsula, Japan, Triggered the 2023 Mw 6.2 Suzu Earthquake During Swarm Activity

Geophysical Research Letters, 2023
An Mw 6.2 earthquake occurred in Suzu, northeastern Noto Peninsula, Japan, on 5 May 2023, followed by many aftershocks. Before this mainshock‐aftershock sequence, an intense earthquake swarm lasted in the vicinity for 2.5 years.

Long-term geomagnetic changes observed n association with earthquake swarm activities in the Izu Peninsula, Japan

Annals of Geophysics, 2001
Anomalous crustal uplift has continued since 1976 in the Izu Peninsula, Japan. Earthquake swarms have also occurred intermittently off the coast of Ito since 1978.

Helium isotope anomaly in groundwater prior to the 2024 Noto Peninsula earthquake [PDF]

Nature Communications
Intense earthquake swarms had been observed on the Noto Peninsula in north-central Japan since December 2020. We report data obtained by periodical groundwater sampling and helium isotope measurements in the epicentre area starting July 2022 for ...

The precursory earthquake swarm in Greece

Annals of Geophysics, 2000
The Hellenic subduction region displays the same precursory swarm phenomenon as has been found in comparable regions of New Zealand and Japan. In the earthquake catalogue of the Aristotle University of Thessaloniki, 10 past sequences of precursory swarms

Examining the Connections Between Earthquake Swarms, Crustal Fluids, and Large Earthquakes in the Context of the 2020–2024 Noto Peninsula, Japan, Earthquake Sequence

Geophysical Research Letters
Earthquake swarms are most commonly composed of small‐magnitude earthquakes. However, a recent study by Yoshida, Uchida, et al. (2023, https://doi.org/10.1029/2023GL106023) analyzed a swarm beneath the Noto Peninsula in Japan that, after more than two ...

Discrete Particle Swarm Optimization for the minimum labelling Steiner tree problem [PDF]

, 2008
Particle Swarm Optimization is an evolutionary method inspired by the social behaviour of individuals inside swarms in nature. Solutions of the problem are modelled as members of the swarm which fly in the solution space.
