Using Keyhole Images to Map Soil Liquefaction Induced by the 1966 Xingtai M_s 6.8 and 7.2 Earthquakes, North China

Remote Sensing, 2023
In March 1966, Ms 6.8 and 7.2 earthquakes occurred in Xingtai, North China, resulting in widespread soil liquefaction that caused severe infrastructure damage and economic losses.

DBA-RTMDet: A High-Precision and Real-Time Instance Segmentation Method for Identification of Damaged Buildings in Postearthquake UAV Imagery

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Unmanned aerial vehicle (UAV) remote sensing plays a crucial role in the rapid assessment of postearthquake-damaged buildings. Existing methods for automatic identification of damaged buildings based on UAV remote sensing imagery primarily focus on ...

The VLF-induced ionospheric perturbations detected by DEMETER during solar minimum

Terrestrial, Atmospheric and Oceanic Sciences, 2023
The VLF-induced ionospheric heating events from the powerful transmitter NWC are collected at extremely low solar activity years of 2008–2009, and their spatial and temporal distribution features are investigated.

Tectonic environment and cause of earthquakes in the Three Gorges reservoir area

Geodesy and Geodynamics, 2011
Seismotectonics in the Three Gorges reservoir area is investigated by using the P-wave tomography with earthquakes that occurred before the impoundment of the reservoir.

Electrical resistivity of three-phase cracked rock-soil medium and its anisotropic changes caused by crack changes

Geomatics, Natural Hazards & Risk, 2020
Electrical resistivity of sedimentary rock-soil is highly variable and governed mainly by a wide range of properties including resistivities of both solid matrix and fluid, cracks or pores, fluid saturation, and crack fabric (e.g.

Late Quaternary Segment Faulting Behavior of Yilan-Yitong Fault and Its Potential Seismic Hazards, NE China, by Using Multisource Remote Sensing Data

Remote Sensing
Quantitative investigation of major fault zones with low slip rates and long recurrence intervals in densely populated regions is essential for understanding earthquake recurrence and assessing seismic hazard.

Variations in seismic parameters for the earthquakes during loading and unloading periods in the Three Gorges Reservoir area

Scientific Reports, 2022
As the largest water conservancy and hydropower project in China, the Three Gorges Reservoir is a weak seismic activity area before impoundment, but the frequency of earthquakes increases significantly after impoundment.

STUDY ON SITE CONDITIONS BASED ON TOPOGRAPHIC SLOPE [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
The travel-time averaged shear-wave velocity to a depth of 30m (Vs30) below the Earth’s surface is widely used to classify sites in many building codes. Vs30 is also used to estimate site classification in recent ground-motion prediction equations (GMPEs)

Bounded earthquakes [PDF]

Proceedings of the American Mathematical Society, 2007
We give a short proof of the fact that bounded earthquakes of the unit disk induce quasisymmetric maps of the unit circle. By a similar method, we show that symmetric maps are induced by bounded earthquakes with asymptotically trivial measures.
