Significant earthquake of magnitude 5.1 just reported 75 km northeast of Ardestan, Iran

A magnitude 5.1 earthquake near Ardestan, Isfahan, Iran, was reported only 10 minutes ago by the German Research Centre for Geosciences (GFZ), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at a shallow depth of 10. km beneath the epicenter late at night on Thursday, October 2nd, 2025, at 11:35 pm local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by the citizen-seismograph network of RaspberryShake, which listed it as a magnitude 5.1 earthquake as well.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Ardestan (pop. 16,100) located 75 km from the epicenter.
