Satellite Remote Sensing in Seismology. A Review

open access: yesRemote Sensing, 2009
A wide range of satellite methods is applied now in seismology. The first applications of satellite data for earthquake exploration were initiated in the ‘70s, when active faults were mapped on satellite images.

New horizon in the statistical physics of earthquakes: Dragon-king theory and dragon-king earthquakes [PDF]

open access: yes地球与行星物理论评
A systematic quantitative investigation into whether the mechanisms of large earthquakes are unique could significantly deepen our understanding of fault rupture and seismicity patterns. This research holds the potential to advance our ability to predict

Investigating the universal character of k–M slope in earthquake catalogs from the Visibility Graph method [PDF]

open access: yesScientific Reports
The b-value of the Gutenberg–Richter law, which describes the magnitude-frequency relationship of seismicity, is the most widely investigated statistical parameters derived from the study of earthquake catalogs.

Temporal distribution characteristics of earthquakes in Taiwan, China

open access: yesFrontiers in Earth Science, 2023
The characteristics of seismic temporal distribution represent an important basis for earthquake prediction and seismic hazard analysis. In this paper, based on the seismic catalogs in Taiwan, and using Poisson (exponential distribution), Gamma ...

Characteristics of the foreshock occurrence for Mj3.0 to 7.2 shallow onshore earthquakes in Japan

open access: yesEarth, Planets and Space, 2022
We use the Japan Meteorological Agency (JMA) earthquake catalogue from January, 2001 to February, 2021 to investigate the spatiotemporal foreshock occurrence for shallow (within 30 km depth) onshore earthquakes (Mj3.0 to 7.2). We find clear peaks for the

Enhanced Tidal Sensitivity of Seismicity Before the 2019 Magnitude 7.1 Ridgecrest, California Earthquake

open access: yesGeophysical Research Letters, 2023
Earth's crust is continuously subjected to oscillatory stress perturbations due to the solid Earth and ocean tides. The seismic response to such stress modulations carries information on earthquake physics and crustal properties.

Gutenberg–Richter B-Value Time Series Forecasting: A Weighted Likelihood Approach

open access: yesForecasting, 2021
We introduce a novel approach to estimate the temporal variation of the b-value parameter of the Gutenberg–Richter law, based on the weighted likelihood approach.

Statistical and clustering analysis of microseismicity from a Saskatchewan potash mine

open access: yesFrontiers in Applied Mathematics and Statistics, 2023
Microseismicity is expected in potash mining due to the associated rock-mass response. This phenomenon is known, but not fully understood. To assess the safety and efficiency of mining operations, producers must quantitatively discern between normal and ...

Incorporating Foreshocks in an Epidemic-like Description of Seismic Occurrence in Italy

open access: yesApplied Sciences, 2023
The Epidemic Type Aftershock Sequence (ETAS) model is a widely used tool for cluster analysis and forecasting, owing to its ability to accurately predict aftershock occurrences.
