The 1945 tsunami led to the death of 300 folks in Pakistan and Oman. If there is yet another tsunami, it could be as effective as the ones that hit Sumatra (Indonesia) in 2004 and Fukushima (Japan) in 2011, professionals say.
“A total of 11 earthquakes have hit the Makran zone so far this year from January to March. These are both offshore and inshore quakes with light to moderate magnitude. These are too small to trigger tsunami,” an official at National Multi Hazard and Early Warning Centre at Public Authority for Civil Aviation, mentioned.
According to probabilistic and deterministic estimates of close to-field tsunami hazards in northeast Oman report by Earthquake Monitoring Centre, Sultan Qaboos University, tsunamis generated along the Makran subduction zone (MSZ) threaten the Sur coast of Oman.
Dr Issa el Hussain, director of the SQU’s Earthquake Monitoring Centre, told Muscat Daily that the eastern element of Makran currently triggered an earthquake in 1945, resulting in a tsunami. But earthquakes which have occurred lately on the fault line have absolutely nothing to do with the probability of tsunami.
“There is a history of Makran causing an earthquake in 1945 which resulted in a tsunami leading to deaths in Oman and the probabilistic data show it could hit again but we don’t know when,” he mentioned. “The recent earthquakes cannot be linked to tsunami because they are small. To trigger tsunami, the earthquake should be more than 6.5 magnitude. What we experienced in this region is that the earthquakes’ mode of motion is horizontal. The worst they can do is landslide.”
The eastern side of Makran is currently identified to create earthquakes.
Recent reports mentioned a validated shallow water numerical code simulates the supply-to-coast propagation and quantifies the coastal hazard in terms of maximum water level, flow depth, and inundation distance.
Researches supply important info for coastal organizing, engineering and management in terms of tsunami hazard and an important step toward tsunami threat reductions in the northwest Indian Ocean.
