From: Infrasound associated with the deep M 7.3 northeastern China earthquake of June 28, 2002
Infrasound source location results based on a grid search using the observed infrasound wave parameters and the infrasound source map. Colored dots indicate infrasound source locations, colored according to travel time. The star marks the location of the seismo-acoustic array CHNAR and triangles indicate seismological stations used for measuring real peak ground motions for the location procedure.
