Exceptionally Elongated Strike‐Slip Rupture Caused by the 2025 MW 7.8 Myanmar Earthquake

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The interplay between fault geometry and rupture behavior remains poorly understood. The 2025 Myanmar earthquake ruptured the Sagaing fault, a major continental strike‐slip fault with simple geometry. We integrated geodetic and teleseismic observations to investigate its rupture process through finite‐fault kinematic inversions and back ...

Micro-seismic source location algorithm based on spatio-temporal distribution of arrival times

Meikuang Anquan, 2023
In order to improve the precision of the micro-seismic hypocenter location and the robustness of algorithms, the objective function construction and spatiotemporal region information use of the location algorithm based on time are studied. The simulation

Injection Induced Seismicity in Complex Fault Zone Architecture

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Modeling of injection‐induced seismicity plays a significant role in understanding the seismic risks associated with different anthropogenic activities including sub‐surface energy harvesting and CO2 ${\text{CO}}_{2}$ sequestration. Here we investigate multi‐cycle modeling of induced seismicity in a complex fault zone hosting a primary fault ...

Hypocenter Locations by a Dense Network.

Journal of Physics of the Earth, 1992
A dense temporary seismograph network was set up in the aftershock area of the 1984 Western Nagano Prefecture Earthquake of M 6.8 by the group for the 1986 Joint Seismological Research in Western Nagano Prefecture. Seismograms of about 1,500 events were obtained during the observation period of 52 days from September 1 to October 22, 1986, and 530 ...

Insights From Two Decades of Seismicity at Columbia Glacier

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract We use Columbia Glacier as a case study to demonstrate how seismically cataloged calving events in Alaska can track glacier evolution over two decades. By combining this catalog—a serendipitous byproduct of earthquake monitoring—with terminus positions, bathymetry, glacier thickness, surface velocity, and environmental records, we show how ...

Relocation Study of Flores Sea Hypocenter (Mw = 7.3) Based on Single Station Estimation Using ObsPy

JGEET: Journal of Geoscience, Engineering, Environment and Technology
One area in Indonesia that is prone to disasters is the Flores Sea area, which has the potential for earthquakes to trigger tsunamis. This is due to the location of Flores, which is in a subduction zone that originates from the collision of the Indo ...

The 2004 and 2005 Sumatra Earthquakes: Implications for the Lisbon earthquake [PDF]

, 2005
The Sumatra mega-earthquake of 26 December 2004 (Mw=9.3) was the strongest earthquake in the world since the 1964 Alaska earthquake and the fifth strongest since 1900. The earthquake occurred at the interface of the India and Burma plates and triggered a
