The earthquake was superficial – 10 km (6 miles) deep – which increases the sensation of shaking on the surface.
About 500,000 people felt strong to very strong, according to the USGS. The earthquake has been felt in several other countries, including Iraq, Syria and Lebanon.
According to the initial USGS estimates, the damage should be “relatively localized” and “there is a low probability of casualties”.
