4.0 quake 27 Dec 7:26 pm (GMT +3:30)
An earthquake of magnitude 4.0 occurred early evening on Sunday 27 December 2020 at 6:56 pm local time near Rāmhormoz, Khuzestan, Iran, as reported by the Iranian Seismological Center (IRSC).
According to preliminary data, the quake was located at a shallow depth of 14 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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.
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 Rāmhormoz (pop. 38,800) located 28 km from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Masjed Soleymān (pop. 111,500) located 52 km from the epicenter, Rāmshīr (pop. 19,500) 72 km away, Omīdīyeh (pop. 47,000) 86 km away, Ahvāz (pop. 841,100) 87 km away, Shūshtar (pop. 77,500) 89 km away, and Aghajari (pop. 21,800) 96 km away.
