How to Differentiate the Blasting Wave and An Earthquake Wave ??
Waveforms generated by an earthquake and an explosion are very different because the source mechanisms are differents.
Earthquake waveforms contains P (longitudinal - similar to acoustic waves) and S (Transverse) waves while explosion waves are mostly dominated by P waves.
Hey @Seismo2 I also found that on Twitter, thought it could help :
Blasts often have these attributes:
• signal coda: a ‘big’ P arrival, can be bigger than the S, and obvious surface waves
• event time: mine blasts are often during the day on the hour or half-hour. And location? 0 km depth at a mine site is obviously a dead giveaway
