A semi-automated algorithm to quantify scarp morphology (SPARTA): application to normal faults in southern Malawi [PDF]
Along-strike variation in scarp morphology reflects differences in a fault's geomorphic and structural development and can thus indicate fault rupture history and mechanical segmentation. Parameters that define scarp morphology (height, width, slope) are

In this study, the model Riccati equation with variable coefficients as functions, as well as a derivative of a fractional variable order (VO) of the Gerasimov-Caputo type, is used to approximate the data for some physical processes with saturation.

Discrepancy between local and moment magnitudes attributed to radiated seismic energy
We investigated the factors contributing to variations in local magnitude (M L ) among earthquakes of comparable moment magnitude (M w ). Specifically, we examined how radiated energy accounts for the difference between M w and M jma (∆M = M w − M jma),

A clustering-based repeating earthquakes identification method and its application
Events with highly similar waveforms and rupturing of the same fault patch are interpreted as repeating earthquakes, which can be applied in detecting deep fault deformation, characterizing fault behavior, and assess seismic hazards.

Evaluation of the favorability of faults to slip: the case of the 2024 Noto Peninsula earthquake
The 2024 Noto Peninsula earthquake (M 7.6) occurred at a depth of approximately 15 km in the eastern part of Noto Peninsula. The high dip angle faults (50–60°) in this area were formed by the extensional stress field during the formation of the Japan Sea.

Earthquake Moment Magnitudes from Peak Ground Displacements and Synthetic Green's Functions
We suggest an approach employing full waveforms from synthetic seismograms to estimate moment magnitudes and their uncertainties from peak amplitudes. The new method is theoretically derived.

Seismic activity in the Noto region of Ishikawa Prefecture, central Japan, has increased since August 2020 and has continued as of August 2023. Stress changes due to subsurface sources and increases in fluid pressure have been discussed as the causes of ...
