The Catastrophic Event: A Night of Terror
The 1990 Iran earthquake struck with brutal force on Thursday, June 21, 1990, at 12:30 a.m. local time (which corresponds to June 20 at 21:00 GMT). This powerful seismic event had its epicenter approximately 15 km (9 mi) from the surface, deep beneath the Gilan province. It occurred specifically between the towns of Rudbar and Manjil in northern Iran, a region situated southwest of the Caspian Sea. The quake registered a moment magnitude of 7.4, though some reports indicated a magnitude of 7.7 on the Ms scale or 7.3 on the Richter scale. Regardless of the slight variations in measurement, it was undeniably a major earthquake, characterized by a Mercalli intensity of X (Extreme), indicating widespread and severe damage.
This particular earthquake was notable not only for its immense power but also for its potential complexity. Some seismologists theorized that the devastating impact may have been amplified by two or more closely spaced earthquakes occurring in rapid succession, effectively compounding the destructive energy released. The 1990 Iran earthquake was, in fact, the largest ever to be recorded in that part of the Caspian Sea region, marking it as a truly exceptional and tragic event in the country's seismic history.
Geological Context: Why Iran is Prone to Earthquakes
Iran is a country highly susceptible to seismic activity, a reality deeply rooted in its complex geological setting. It lies within the Alpine-Himalayan orogenic belt, a vast region where the Arabian Plate is actively colliding with the Eurasian Plate. This ongoing tectonic collision creates immense stresses within the Earth's crust, leading to the formation of numerous active faults across the Iranian plateau. The northern part of Iran, where the 1990 earthquake occurred, is particularly active due to the convergence and deformation of these massive lithospheric plates.
The specific area around Gilan and Zanjan provinces is characterized by a network of significant fault lines. The energy accumulated along these faults is periodically released in the form of earthquakes, making seismic events a recurring and unfortunate aspect of life for Iranians. Understanding the intricate geology and seismology of the area is crucial for comprehending the frequency and intensity of the earthquakes that strike this nation. The 1990 event was a stark reminder of these powerful geological forces at play.
