A case-based reasoning method of recognizing liquefaction pits induced by 2021 MW 7.3 Madoi earthquake

Earthquake Research Advances, 2023
Earthquake-triggered liquefaction deformation could lead to severe infrastructure damage and associated casualties and property damage. At present, there are few studies on the rapid extraction of liquefaction pits based on high-resolution satellite ...

Contemporary crustal tectonic movement in the southern Sichuan-Yunnan block based on dense GPS observation data

Earth and Planetary Physics, 2019
We analyzed 360 permanent and campaign GPS data from 1999 to 2017 in the southern Sichuan-Yunan block, and obtained crustal horizontal deformation in this region. Then, we derived the strain rate using a multi-scale spherical wavelet method.

Contribution of deep-earth fluids to the geothermal system: A case study in the Arxan volcanic region, northeastern China

Frontiers in Earth Science, 2023
Investigations of the hot spring water and gas in the volcanic region are involved in assessing geothermal resources and understanding groundwater circulation, volcano, and earthquake activities.

Stress-Related Pre-Seismic Water Radon Concentration Variations in the Panjin Observation Well, China (1994–2020)

Frontiers in Earth Science, 2020
Continuous observation data from a period of 26 years show that water radon concentrations in the Panjin observation well document pre-seismic anomalies prior to earthquakes of 4.8 ≤ M ≤ 7 within a radius of 300 km.

A review of the seismotectonics of the Makran Subduction Zone as a baseline for Tsunami Hazard Assessments

Geoscience Letters, 2019
The Makran Accretionary Wedge (900 km across) is a consequence of northward subduction of the oceanic part of the Arabian Plate beneath the Lut and Afghan blocks in the northwestern Indian Ocean.

Reverse Detection of Short-Term Earthquake Precursors [PDF]

, 2003
We introduce a new approach to short-term earthquake prediction based on the concept of selforganization of seismically active fault networks. That approach is named "Reverse Detection of Precursors" (RDP), since it considers precursors in reverse order ...

Implications for prediction and hazard assessment from the 2004 Parkfield earthquake [PDF]

, 2005
Obtaining high-quality measurements close to a large earthquake is not easy: one has to be in the right place at the right time with the right instruments. Such a convergence happened, for the first time, when the 28 September 2004 Parkfield, California,

Research progress on layered seismic anisotropy - A review

Earthquake Research Advances, 2021
Seismic anisotropy is an effective feature to study the inner structure of the Earth. In complex tectonic area, the assumption of single-layer anisotropy is sometimes not well consistent with the observed data; thus, the assumption of multi-layered (i.e.

Theory of Earthquake Recurrence Times [PDF]

, 2006
The statistics of recurrence times in broad areas have been reported to obey universal scaling laws, both for single homogeneous regions (Corral, 2003) and when averaged over multiple regions (Bak et al.,2002).
