Crustal thicknesses and Poisson's ratios beneath the Chuxiong-Simao Basin in the Southeast Margin of the Tibetan Plateau

Earth and Planetary Physics, 2019
In the Southeast Margin of the Tibetan Plateau, low-velocity sedimentary layers that would significantly affect the accuracy of the H-κ stacking of receiver functions are widely distributed.

Earthquake prediction

Bulletin of the New Zealand Society for Earthquake Engineering, 1978
The study of precursory phenomena shows increasing promise as a basis for earthquake prediction. Long-range forecasting can be expected to reduce by a large factor the uncertainty of estimates based on the historical record, and also to facilitate the development of short-range forecasting.

High Resolution Seismicity Smoothing Method for Seismic Hazard Assessment

Russian Journal of Earth Sciences
A high resolution smoothing method is proposed for performing local estimates of the parameters of the Gutenberg-Richter law (GR). Using this method, the smoothing radius can be chosen large enough to ensure that the condition of applicability of GR law ...

Mainshocks are aftershocks of conditional foreshocks: How do foreshock statistical properties emerge from aftershock laws [PDF]

, 2003
The inverse Omori law for foreshocks discovered in the 1970s states that the rate of earthquakes prior to a mainshock increases on average as a power law ~ 1/(t_c-t)^p' of the time to the mainshock occurring at t_c.

Gravity pattern in southeast margin of Tibetan Plateau and its implications to tectonics and large earthquakes

Earth and Planetary Physics, 2019
There are many active faults in the southeast margin of Tibetan Plateau, where three large active faults zones, the Longmenshan, Xianshuihe and Anninghe, merge to form a "Y" shape. Strong crustal deformation and a complicated fault distribution accompany

Synergistic combination of systems for structural health monitoring and earthquake early warning for structural health prognosis and diagnosis [PDF]

, 2012
Earthquake early warning (EEW) systems are currently operating nationwide in Japan and are in beta-testing in California. Such a system detects an earthquake initiation using online signals from a seismic sensor network and broadcasts a warning of the ...

A Partial Molten Low‐Velocity Layer Atop the Mantle Transition Zone Beneath the Western Junggar: Implication for the Formation of Subduction‐Induced Sub‐Slab Mantle Plume

Geochemistry, Geophysics, Geosystems, 2022
Deep subduction of plate generally could induce a partial molten low‐velocity layer (LVL) atop the mantle transition zone (MTZ) around the subduction zone.
