Sound wave theory was used for qualitative pattern of seismic wave distribution around blasting. Results show changing of seismic waves from round to elliptical shape during distribution through rock massif with cracks. http://pubs.sciepub.com/ajcea/4/2/2/ajcea-4-2-2.pdf blasting charge seismic wave crack rock massif seismic hazard rock mechanics
