ShakeMap (Calculated intensity of this Iran earthquake):
Over the past few weeks, the Iranian province Hormozgan has been hit by a seuqnece of several big earthquakes. Two new ones happened on Saturday. Accoding to the Iranian Seismological Center the quakes with Magnitude 5.8 and 5.9 happened shortly after 4 pm UTC. The epicenters were located between the mainland and the popular touristic Island Qeshm. Both quakes were shallow and south of the previous quakes. Therefore, new severe damage can be expected, especially on Qeshm. Shaking of this quake was felt widely across the southern Persian Gulf, including Dubai (UAE) and Doha (Qatar).
Previously on July 1st, three earthquakes of Magnitude 6 happened onshore and caused severe destruction in several villages and significant soil liquefaction. At least seven people died in this event sequence, more than 100 were injured. Multiple strong aftershocks followed over the weeks. Today’s quakes are the southern extention of this sequence. A new uptick of seismicity (aftershocks) can be expected over the next few weeks. However, it is unclear how the situation will further develop.
Current earthquake activity in Iran:
In the past 30 days, 43 earthquakes of magnitude 3.9 or higher were detected in Hormozgan, Iran (see map section). Therefore, the earthquake activity of the past month has been much higher relative to long-term trends (more than 20% deviation).
Since 1960, 35 earthquakes larger than Magnitude 5.9 were detected in this region. This makes an average of 0.6 earthquakes larger than M5.9 per year in Iran. Therefore, the general earthquake activity is usually very high and quakes of this size have an average recurrence time of approx. 1.7 years (20 months).
