Long‐Living Earthquake Swarm and Intermittent Seismicity in the Northeastern Tip of the Noto Peninsula, Japan

open access: yesGeophysical Research Letters, 2023
The factors controlling earthquake swarm duration are remain unclear, especially in the long‐living ones. A severe earthquake swarm struck the tip of the Noto peninsula, Japan.

Earthquake swarms in Greenland

open access: yesGeological Survey of Denmark and Greenland Bulletin, 2014
Two earthquake swarms have been detected in Greenland. One occurred on the island of Disko in August 2010, the other one was active from January 2008 to June 2009 near the South-East Greenland coast c. 200 km south of Tasiilaq. An earthquake swarm is defined as a series of earthquakes of similar magnitude located within a small area.

Earthquake's swarms as forerunners of strong earthquakes in Italy

open access: yesAnnals of Geophysics, 2010
SUMMARY - Most of strong earthquakes in Italy seem to be preceded by<br />anomalous swarms of weaker shocks. Similiar precursor was described by<br />Prozoroff and al (1972) for Central Asia. Most often the swarms occur near<br />the same lineament, as the strong earthquake which follow them.

The 2025 South Aegean Sea Seismic Swarm Activity in Natural Time and the Generalized Gutenberg–Richter Law

open access: yesApplied Sciences
A strong seismic swarm occurred in the south Aegean Sea from late January to March 2025. Here, we apply natural time analysis (NTA), which can identify the critical stage before strong earthquakes, and find that all earthquakes of magnitude five or ...

Migration diffusivity as a controlling factor in the duration of earthquake swarms

open access: yesEarth, Planets and Space, 2021
Earthquake swarms exhibit highly uncertain temporal behavior. We investigated the relationship between the swarm duration and the diffusivity of hypocenter migration for triggered earthquake swarms in northeastern Japan.

Earthquake Swarm Activity in the Tokara Islands (2025): Statistical Analysis Indicates Low Probability of Major Seismic Event

open access: yesGeoHazards
The Tokara Islands, a volcanic archipelago located south of Japan’s main islands, experienced earthquake swarm activity in 2025. Public concern has emerged regarding the potential triggering of the anticipated Nankai Trough earthquake, which the Japan ...

Post-earthquake assessment of moderately damaged reinforced concrete plastic hinges

open access: yes, 2020
Modern reinforced concrete buildings are often designed to dissipate energy during strong earthquakes by permitting the controlled formation of plastic hinges. Plastic hinges require assessment of residual capacity in post-earthquake situations. However,
