Tehran, Feb 14, IRNA -- A relatively strong earthquake, measuring 5.1 degrees on the open-ended Richter scale, shook parts of Bandar Abbas off the Persian Gulf, on Friday with no immediate report of property damage or probable casualty.

The Geophysics Institute of Tehran University said its seismological bases had recorded a tremor at 14:01 (1031 GMT) to the northeast of Bandar Abbas, the capital city of Hormuzgan province.

Earlier in the day, another quake with the intensity of 3.9 hit parts of Shiraz and Arsanjan (ed.) in the southern Fars province.

Tehran University's seismological bases registered the temblor at 13:20 hours.

Iran is situated on some of the world's seismic faultlines and quakes of minor magnitudes are very common.

On Thursday, an earthquake of 3.9 magnitude shook the city of Khorramabad in the Lorestan province.

Quake jolts Shiraz

An earthquake measuring 3.9 on the open-ended richter-scale jolted parts of the Fars province on Friday.

No report is available of the eventual damage caused as a result of the quake which rocked the northeastern parts of Shiraz, capital of Fars, as well as the south of Arjestan township.

The seismological center of the Tehran University Geophysical Institute has put the epicenter of the tremor at about 78 kilometer north east of Shiraz.

Iran sits on some of the world's seismic fault lines and is often shaken by earthquakes of various intensities. Since 1991, over 950 earthquakes have hit the country, resulting in the death of 17,600 people and injuries to 53,300 others.

As Iran is situated on a quake faultline, the seismologists predict a major earthquake may strike Tehran in future.

The Majlis earlier in the year delegated a special committee to coordinate the actions of various organizations against a possible earthquake in Tehran.
