Groundwater level and temperature changes following the great Tangshan earthquake of 1976 near the epicenter

Geomatics, Natural Hazards & Risk, 2023
Several meters of rise in groundwater level with significant changes in groundwater temperature were observed near the epicenter of the 1976 Tangshan earthquake—an intraplate earthquake with a magnitude of MS=7.8 that occurred in northern China.

Seismicity characterization of oceanic earthquakes in the Mexican territory [PDF]

Solid Earth, 2020
We analyzed the seismicity of oceanic earthquakes in the Pacific oceanic regime of Mexico. We used data from the earthquake catalogues of the Mexican National Service (SSN) and the International Seismological Centre (ISC) from 1967 to 2017.

Deep lithospheric structures along the southern central Chile Margin from wide-angle P-wave modellilng [PDF]

, 2009
Crustal- and upper-mantle structures of the subduction zone in south central Chile, between 42 degrees S and 46 degrees S, are determined from seismic wide-angle reflection and refraction data, using the seismic ray tracing method to calculate minimum ...

Rheological control of Wadati-Benioff zone seismicity [PDF]

, 1988
Intermediate and deep focus earthquakes in Wadati-Benioff zones are thought to occur in the cold interiors of downgoing slabs which are significantly stronger than the warmer mantle.

Intraplate Earthquakes in Iraqi Western Desert [PDF]

Kirkuk University Journal-Scientific Studies, 2010
The seismicity of Iraqi western desert was analyzed. During the period from 1900 to 2004, there occurred about 40 events with magnitude Mw ≥ 3.0.The area was inactive before 1970.This may be attributed to quietness of the area and / or to missing of data and the poor coverage for the local and regional seismic stations.

Crustal and Upper Mantle Shear Wave Velocity Structure of Botswana: The 3 April 2017 Central Botswana Earthquake Linked to the East African Rift System

Geophysical Research Letters, 2020
Rayleigh wave group and phase velocity measurements obtained from ambient noise and earthquake data at 51 broadband stations were used to construct the first 3‐D crustal and upper mantle shear wave velocity model of Botswana.

Intraplate seismicity in northern Central Europe is induced by the last glaciation [PDF]

, 2015
There is growing evidence that climate-induced melting of large ice sheets has been able to trigger fault reactivation and earthquakes around the migrating ice limit.

A physical understanding of large intraplate earthquakes [PDF]

Earth, Planets and Space, 2014
We examined several previously proposed models of the process by which large intraplate earthquakes are generated, and found the most plausible to be the ‘localized shear model,’ in which seismogenic faults have downward extensions in the lower crust and the localized shear deformation on the downward extensions accumulate stress on the seismogenic ...
