Temporal and spatial characteristics of VTEC anomalies before Wenchuan Ms8.0 earthquake

Seismoionospheric GPS total electron content anomalies observed before the 12 May 2008 Mw7.9 Wenchuan earthquake

[1] The global ionospheric map (GIM) is used to observe variations in the total electron content (TEC) of the global positioning system (GPS) associated with 35 M 6.0 earthquakes that occurred in China during the 10-year period of 1 May 1998 to 30 April 2008. The statistical result indicates that the GPS TEC above the epicenter often pronouncedly decreases on day 3–5 before 17 M 6.3 earthquakes...

Stress evolution and fault interactions before and after the 2008 Great Wenchuan earthquake

identification of the spatial-temporal anomalies sea level pressure

abstract: identification of spatial-temporal anomalies sea level pressure in part of northern hemisphere was the main aim in this research. for this purpose six hourly data used from the to eastern longitude and to northern latitude. in this location, there are 825 pixels to geographical degree. therefore, database extent created. in this matrix, 825 are number of the pixels at that location an...

Tectonic Background of the Wenchuan Earthquake

inverse statistics method: spatial and temporal dependence in earthquake

the aim of this work is to understand the relation between time and place that an earthquake takes place. in order to answer this question, the modified level crossing (mlc) technique has been implemented. by studying two earthquakes, one in iran and one in california we came to the conclusion that there is a relation between time and place of an earthquake occurrence. as a matter of fact, this...
