Observed Seismic Intensities and Damage Pattern in Central Mexico during Intraslab Earthquakes of 1999 (Mw6.9) and 2017 (Mw7.1)

Geofísica Internacional, 2020
El patrón y nivel de daño en la región de México Central durante el sismo de septiembre de 2017 Mw7.1 en Morelos-Puebla son diferentes a los observados durante el sismo de Tehuacán (Mw6.9) en 1999 a pesar de que ambos sismos intraplaca tienen magnitudes ...

High‐Resolution Interseismic Strain Mapping From InSAR Phase‐Gradient Stacking: Application to the North Anatolian Fault With Implications for the Non‐Uniform Strain Distribution Related to Coseismic Slip Distribution

Geophysical Research Letters, Volume 50, Issue 15, 16 August 2023., 2023
Abstract High‐resolution interseismic strain mapping is important for studying faulting behavior and for assessing seismic hazards. Interferometric Synthetic Aperture Radar has been widely applied to measure interseismic deformation along active strike‐slip faults. However, phase unwrapping errors and over‐smoothing effects limit its ability to map the

Active Deformation Pattern in the Western Flank of the Central Taurides, Southern Margin of the Central Anatolian Plateau: Inferences From Geomorphic Markers and Kinematic Indicators

Tectonics, Volume 42, Issue 6, June 2023., 2023
Abstract The southwestern margin of the Central Anatolian Plateau corresponds to the upper crust of the subduction between African and Anatolian plates, with a high relief of up to 2 km. This mountainous region has distinctive geomorphological features and presents a unique setting to investigate the mechanism of orogenic plateau margin development ...

Tectonic Evolution of a Sedimented Oceanic Transform Fault: The Owen Transform Fault, Indian Ocean

Tectonics, Volume 42, Issue 5, May 2023., 2023
Abstract The Owen transform fault (OTF) connecting the Sheba and the Carlsberg spreading ridges in the Indian Ocean currently forms the active plate boundary between India and Somalia plates. This 330‐km‐long transform fault is by far the longest transform fault along the India‐Somalia plate boundary and its valley is buried under the thick distal ...

Sea Level Changes Affect Seismicity Rates in a Hydrothermal System Near Istanbul

Geophysical Research Letters, Volume 50, Issue 3, 16 February 2023., 2023
Abstract Small stress changes such as those from sea level fluctuations can be large enough to trigger earthquakes. If small and large earthquakes initiate similarly, high‐resolution catalogs with low detection thresholds are best suited to illuminate such processes. Below the Sea of Marmara section of the North Anatolian Fault, a segment of ≈ $\approx

An Analytic Expression for the Volcanic Seismic Swarms Occurrence Rate. A Case Study of Some Volcanoes in the World

Earth and Space Science, Volume 10, Issue 2, February 2023., 2023
Abstract Seismic swarms are defined as a group of earthquakes occurring very close in time and space but without any distinctively large event triggering their occurrence. Up to now no simple law has been found to describe the swarm occurrence rate. Here we find an expression able to fit the average occurrence rate on some volcanic areas.

Probabilistic prediction of the next large earthquake in the Michoacán fault-segment of the Mexican subduction zone

Geofísica Internacional, 2003
La estimación del intervalo de tiempo Æt hasta el siguiente sismo fuerte, que es esperado en una región sísmica, es un problema difícil. Dentro del método más convencional de predicciones basadas en el intervalo de tiempo (Æt), dada una distribución ...

Re‐examination of the 1928 Parral, Mexico earthquake (M6.3) using a new multiplatform graphical vectorization and correction software for legacy seismic data

Geoscience Data Journal, Volume 10, Issue 1, Page 178-192, January 2023., 2023
Re‐examination of historical earthquakes from legacy seismic data requires reliable vectorization and correction of analog seismograms. Nowadays, computational capabilities allow the development of ad‐hoc programs to perform such analysis. In this work we use Tiitba, our own developed Python based‐software to vectorize, analyze and correct the analog ...
