The mention of a tsunami often evokes fear of widespread destruction. In the past, tsunamis attributed to hurricanes have caused severe devastation in Pakistan and many other parts of the world. Recently, frequent earthquakes in Karachi have raised concerns about the possibility of a tsunami in the port city.
On Wednesday, June 19, at 9:26 a.m., earthquake tremors were felt in Karachi. The earthquake had a magnitude of 3.2, with an epicenter located 32 km southwest of Karachi at a depth of 42 km in the Arabian Sea. This was the third earthquake in Karachi this year.
Historically, Karachi has faced the devastating effects of tsunamis. In 1945, a tsunami struck the coast of Karachi and nearby areas. Although the population of Karachi was much smaller at that time, thousands of people perished in the disaster.
The intensity of the 1945 tsunami was 8.8. Experts warn that if an earthquake with a magnitude of 8 or higher occurs again along the coast of Karachi, it could trigger another catastrophic tsunami.
In addition to Karachi, the coasts of Balochistan also face tsunami risks. There is a subduction zone near the Makran Sea where an earthquake can occur at any time. Scientists worldwide agree that this area is highly susceptible to large tsunamis. Due to its proximity, cities like Gwadar, Ormara, and Pasni could be severely affected.
The effects of the 1945 tsunami are still visible in Karachi today, with marks on the city’s lighthouse serving as a reminder. According to experts, in the case of a tsunami, Karachi would have 60 to 87 minutes to evacuate people to safe locations, while Gwadar and Pasni would have only 13 minutes.
