Moderate magnitude 4.1 earthquake 28 km southwest of Hashtpar, Iran

4.1 quake 22 Jul 10:54 pm (GMT +4:30)
4.1 quake 22 Jul 10:54 pm (GMT +4:30)
An earthquake of magnitude 4.1 occurred late at night on Friday, July 22nd, 2022, at 10:24 pm local time near Hashtpar, Gilan Province, Iran, as reported by the European-Mediterranean Seismological Centre (EMSC).
According to preliminary data, the quake was located at a shallow depth of 10 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.
A second report was later issued by the citizen-seismograph network of RaspberryShake, which listed it as a magnitude 4.1 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 Khalkhāl (pop. 51,000) located 21 km from the epicenter, and Hashtpar (pop. 45,300) 28 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Fūman (pop. 27,800) located 62 km from the epicenter, Bandar-e Anzali (pop. 110,800) 62 km away, Rasht (pop. 594,600) 80 km away, Rasht (pop. 594,600) 80 km away, Ardebil (pop. 410,800) 86 km away, and Āstārā (pop. 39,100) 96 km away.
