Source Mechanism and Rupture Directivity of the 18 May 2009 M_W 4.6 Inglewood, California, Earthquake [PDF]

, 2010
On 18 May 2009, an M_w 4.6 earthquake occurred beneath Inglewood, California, and was widely felt. Though source mechanism and its location suggest that the Newport–Inglewood fault (NIF) may be involved in generating the earthquake, rupture directivity ...

Seismotectonics of Zimbabwe

African Journal of Science and Technology, 2009
The seismotectonics of Zimbabwe is presented in this paper. Data used in the study are from instrumental records for the period 1910-1991 sourced from available seismological bulletins. Earthquake magnitudes are unified to surface-wave magnitude (Ms), facilitating easy evaluation of seismicity of the region. Seismicity is confined to regions with broad

Seismicity and Seismotectonics in the Cantabrian‐Pyrenean Zone (N Spain) Using a Dense Temporary Network of Broadband Seismic Stations

Tectonics, Volume 45, Issue 3, March 2026.
Abstract Earthquakes in intraplate regions are often scattered and difficult to associate with specific geological structures, requiring detailed surveys to identify active faults. Improving knowledge of local seismicity in these areas is essential for accurate seismic hazard assessment and for safe planning of economic activities that could affect ...

Mechanism of 2003, 2007 and 2009 earthquakes (S. Vicente Cape) and implications for the 1755 Lisbon earthquake [PDF]

, 2012
The San Vicente Cape region (SW Iberia) is of great seismological interest due to its tectonic complexity and for the occurrence of the 1755 Lisbon mega-earthquake.

High‐Resolution Satellite Imagery Mapping of the Surface Rupture and Slip Distribution of the Sagaing Fault in the 28 March 2025 Mw 7.7 Earthquake, Myanmar

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract On 28 March 2025, a Mw 7.7 earthquake occurred on the Sagaing Fault in Myanmar. Security constraints prevented timely field investigations on its surface rupture, hindering analysis of seismotectonics and rupture dynamics. Using high‐resolution satellite imagery, we mapped a ∼420 km surface rupture and measured 540 dextral offsets, revealing ...

Smart Speed Imaging in Digital Image Correlation: Application to Seismotectonic Scale Modeling

Frontiers in Earth Science, 2019
Analog models of earthquakes and seismic cycles are characterized by strong variations in strain rate: from slow interseismic loading to fast coseismic release of elastic energy.

Seismicity and Ground Motion Simulations of the SW Iberia Margin [PDF]

, 2010
In this study, we focus on the region between Gorringe Bank and the Horseshoe Fault located in the SW Iberia margin, which is believed to be the site of the great 1755 earthquake.

Indications of a link between seismotectonics and CH4 release from seeps off Costa Rica [PDF]

, 2007
Measurements of CH4 concentrations in the bottom water during two discrete sampling periods in subsequent years above different cold seeps at the Pacific margin off Costa Rica indicate large-scale variations of CH4 release.

Sedimentary records of palaeohydrological variability during the Late Holocene in the Lower Narmada Basin, western India

The Depositional Record, Volume 12, Issue 1, February 2026.
Late Holocene palaeohydrological changes in the lower Narmada Basin, India, revealed using multiproxy analyses of the Orsang River terrace sediments. Distinct depositional phases corresponding to global climatic events were recorded. High‐magnitude floods in the Narmada River during the MWP, and within the tributary Orsang River during DACP and LIA ...

The Al Hoceima earthquake of May 26, 1994 and its aftershocks: a seismotectonic study

Annals of Geophysics, 1998
The present paper focuses on the moderate earthquake that occurred on May, 26, 1994, at 8 h 27 min, which caused great damage and two deaths. The epicentre of the main shock was located at 35.280N, 3.990W. The focal depth was 13 km, and the magnitude (Md)
