- •
We have used completely new data sets recorded by dense seismic network of Gujarat.
- •
Crack attributes of earthquakes (Mw 4.8, 5.0 & 5.1) have been examined.
- •
High-crack density, -saturation rate and -porosity anomalies are imaged at mainshock.
- •
Pore collapse due to saturation of the sub-surface cracked rock matrix
- •
Heavy rainfall during Indian Monsoon may be a causative agent in triggered earthquake.
