Lurker Posted February 7 Report Share Posted February 7 On February 6, around 4:15 a.m. local time, a magnitude 7.8 earthquake struck south central Turkey near the Turkey/Syria border. Just 11 minutes later, it was followed by a magnitude 6.7 aftershock. The largest aftershock at the time of writing was a M7.5 aftershock which struck 95 km (~60 miles) to the north. USGS observations and analyses indicate all these events are occurring within the East Anatolian fault system. Though an earthquake of this magnitude is rare anywhere in the world, this type of event is generally expected on long, plate-boundary strike-slip faults. “It’s difficult to watch this tragedy unfold, especially since we’ve known for a long time about how poorly the buildings in the region tend to behave in earthquakes,” said USGS scientist David Wald. “An earthquake this size has the potential to be damaging anywhere in the world, but many structures in this region are particularly vulnerable.” The two largest earthquakes in the recent series are relatively shallow, with the mainshock 18 kilometers, or 11 miles, deep and the 7.5 magnitude aftershock at 10 kilometers (just over 6 miles) deep. Because the quakes are relatively shallow, the intensity of the shaking is severe. source : USGS Quote Link to comment Share on other sites More sharing options...
