Iran Rattled by Over 120 Earthquakes in Just One Week: What You Need to Know
During the week from August 16 to 22, Iran experienced a notable surge in seismic activity, with a total of 119 earthquakes recorded across various provinces. This increase in earthquakes highlights the seismic volatility of the region, drawing attention from both locals and researchers alike.
According to the Institute of Geophysics of the University of Tehran, the recorded earthquakes can be categorized as follows:
- 101 earthquakes had magnitudes smaller than 3.
- 16 earthquakes registered magnitudes between 3 and 4.
- 2 earthquakes were measured with magnitudes between 4 and 5.
Notably, one significant earthquake occurred on August 21 in Kerman province, which had a magnitude of 4 on the Richter scale. This event underscores the ongoing seismic risks in the area.
Among the provinces that experienced the most seismic activity, Kerman topped the list with a total of 14 earthquakes. Following closely was Khorasan Razavi province, which recorded 13 earthquakes. Interestingly, during this period, Tehran province also experienced an earthquake.
Conversely, several provinces reported no seismic activity, including:
- East Azarbaijan
- West Azarbaijan
- Ardabil
- Ilam
- Zanjan
- Sistan-Baluchestan
- Qazvin
- Kordestan
- Gilan
- Markazi
This week’s total of 119 earthquakes marks a notable increase, with 32 more earthquakes compared to the previous three weeks. The trend in recorded earthquakes had been declining, with counts dropping from 163 in the first week to 117 and then to 87 in the following weeks.
Looking at the broader picture, the seismic landscape of Iran over the past calendar year (from March 2024 to March 2025) paints a more comprehensive picture. A total of 6,272 earthquakes were documented throughout the country. Among these, 150 earthquakes exceeded a magnitude of 4 on the Richter scale. Impressively, at least five earthquakes with a magnitude greater than 4.5 occurred each month.
The Iranian plateau is situated in a highly seismically active region, known for both catastrophic earthquakes and other natural hazards. This geographical positioning contributes significantly to the region’s seismic profile.
Statistically, Iran experiences around 2 percent of the world’s earthquakes. However, it is noteworthy that more than 6 percent of the global earthquake-related fatalities in the 20th century were attributed to seismic events in Iran.
In summary, the recent seismic activity in Iran serves as a reminder of the geological forces at play in the region. With ongoing monitoring by the Institute of Geophysics, it is essential for residents and authorities to remain vigilant and prepared for potential future earthquakes.
