Western Makran Earthquake of 18 February 1483, Mw 7.7
Western Makran Earthquake of 18 February 1483, Mw 7.7
On November 3, 1482, a series of foreshocks began, culminating three month later on 18th February 1483 in a destructive Mw7.7 earthquake in the Strait of Hurmuz. In “Jarun” the earthquake damaged or threw down certain tall buildings, the minarets of the mosques and the ventilation chimneys (badgirs) of the houses. About the period northeast Oman was also affected by an earthquake. The details of the effects of the shock in Hurmuz suggest that the island was some distant from the epicentral region of a large magnitude earthquake. The absence of data from the Persian mainland, and the reference to the earthquake in Oman, suggest therefore the further possibility that the shock originated offshore from the western coast of Makran.

Mohammadabad Earthquake of 16 February 1941, Ms 6.1
Mohammadabad Earthquake of 16 February 1941, Ms 6.1
In the early Night of 16th February 1941, an earthquake with a magnitude Ms = 6.1 caused heavy damages to the sparse populated Mohammdabad area in the north west of Birjand. The city was completely destroyed and 680 out of its 920 residents were killed. Evidences indicate that the earthquake has been associated with a surface fault rupture which was located about 4 km south of Ghomenjan with a length of 8 to 10 km toward the south. The surface rupture had a N-80-E trend with some vertical displacement lees than 1 meter. The February 16, 1941 earthquake caused widespread clay liquefaction in the east and south of Mohammadabad where the groundwater table at the time of the earthquake was very close to the ground surface. The ground collapsed between Mohammadabad and Teghdar and mud spilled out of its cracks. The city of Mohammadabad was again built about 500 meters north of its former place and many townships that were destroyed, were abandoned. The earthquake was felt strongly in Birjand and Ghaen and Torbat-e Heydarieh.
Ghaen Earthquake of 15 February 1549, Ms 6.7
Ghaen Earthquake of 15 February 1549, Ms 6.7
On 15th February 1549, a strong earthquake with a magnitude Ms = 6.7 occurred in the eastern region of “Ghaen” at the 33.7N and 60E coordinates. The event completely destroyed five villages, probably in the region of “Zirkouh” and 3000 people were killed. It seems that the city of Ghaen had faced no heavy damages because it was located somewhat far from the earthquake epicentral area.

Herat Earthquake of 10 February 1364, Ms 5.8
Herat Earthquake of 10 February 1364, Ms 5.8
On 10th February 1364, a devastating earthquake with a magnitude Ms = 5.8 occurred in the region of “Herat” at the 34.9N and 61.7E coordinates. Due to this event, most buildings of the city, especially tall structures were destroyed. Although most of the damages were observed in “Herat”, the details of this earthquake creates the impression that the epicenter of the event had occurred a little farther away, maybe in “Gulran”.

Lahijan Earthquake of 3 February 1678, Ms6.5
Lahijan Earthquake of 3 February 1678, Ms6.5
On February 3, 1678, an earthquake of magnitude Ms=6.6 and epicentral coordination of 37.2N and 50E occurred in Lahijan. It destroyed at Lahijan the Mesdjid-i-Djame and its minarets, together with many sanctuaries, public baths, bridges and a very large number of houses. Many Shocks continued for ten hours.
Rigan Earthquake of 27 January 2011, Mw 6.2
Rigan Earthquake of 27 January 2011, Mw 6.2
At 12:08 local time on Thursday, January 27, 2011, an earthquake with a magnitude of Mw=6.2 and epicentral coordinates of 28.15N 59.09E struck the Rigan region in the Kerman province. The event, with a NW-SE strike-slip mechanism, was the biggest aftershock of the December 20, 2010 earthquake (Mw=6.5) occurred on the Kahurak fault. It is noteworthy that on January 27 and 28, 2011, about 68 seismic events were recorded with magnitude of ML=2.8 to 6.2 in the southeast of the Mohammad Abad Rigan region. Therefore, the Rigan earthquake of January 27 can be considered as a large aftershock which had its own aftershocks and created a secondary aftershock sequence. Fortunately, the earthquake had no casualties, while 70% of the homes and gardens of Chah Qanbar and an agricultural well were destroyed and roads of the area were blocked.
