Swarm of Small Quakes Rattles Rajkot District in Gujarat, No Damage Reported

Seismologists point to groundwater-related pore pressure as the likely driver of the low-magnitude swarm.

  • Rajkot District Collector Om Prakash reported a total of 21 tremors in Upleta, Dhoraji and Jetpur, ranging from magnitude 1.4 to 3.8.
