A new double-difference earthquake relocation algorithm for models with complex velocity structure
International Meeting for Applied Geoscience & EnergyTraditional double-difference approaches for earthquake relocation are established based on a least-squares framework that enables the minimization of the observed and modeled traveltime difference between earthquake pairs by iteratively adjusting the locations and origin times of a cluster of earthquake events.

On January 10, 1998, at 11h50min Beijing Time (03h50min UTC), an earthquake ofM L=6.2 occurred in the border region between the Zhangbei County and Shangyi County of Hebei Province. This earthquake is the most significant event to have occurred in northern China in the recent years.

AbstractWe simultaneously relocate the M ≥ 1.0 earthquakes occurred from July 2005 to December 2014 in Xiaowan reservoir area, which is located in an active tectonic region in the middle and lower section of Lancang Jiang in western Yunnan province of China, using cross‐correlation (CC) and double‐difference (DD) method.

AbstractCombining the data recorded at the mobile seismic network with those from the regional network, we relocated 404 aftershocks of ML ≥3.5 of the 2003 Bachu‐Jiashi, Xinjiang MS6.8 earthquake by the double‐difference method and made theoretical analysis of the feasibility. We got a result of significant improvement.

Eastern Canada is located within the North American Plate and, therefore, should have a relatively low rate of earthquake activity compared with interplate boundary. However, large earthquakes do occur in the region, especially in the Charlevoix Seismic Zone (CSZ) located about 100km downstream from Quebec City.
