A mild earthquake measuring 4.2 on the Richter scale has rattled the outskirts of Kaki, a city in the Iranian province of Bushehr.

According to Tehran University's Geophysics Institute, the quake occurred at 23:47 local time Monday (2017 GMT).

The Institute registered the epicenter of the quake in an area defined as 51.46 degrees longitude and 28.23 degrees latitude.

No report has yet been received of casualties or property damage from the quake.

Iran is frequently affected by earthquakes of varying magnitudes, as it sits on some of the world's most active seismic fault lines. At least one minor earthquake is recorded everyday.

Seismologists point out that Iran is at the junction of three tectonic plates and is literally being 'squeezed' by them.
