![]() That means a magnitude six earthquake shakes the ground ten times more than a magnitude 5. The seismic wave amplitude recorded on the seismogram is ten times greater for each increase of 1 unit on the Richter scale. The effects of the quake were felt across West Asia, Northern Africa and South Eastern Europe with residents of Lebanon, Cyprus, Greece, Israel and Egypt also reporting tremors, wrote The Guardian. The Richter scale is a logarithmic scale based on powers of 10. This is a highly populous region, exponentially increasing the likelihood of casualties. Geological Survey (USGS) said the quake was centred about 33 km from Gaziantep, around 18 km deep, reported AP. Earthquake magnitudes are given using one of several broadly equivalent scales, with the moment magnitude scaling being the preferred measure of an. Most large earthquakes have occurred along the Northern Anatolian Fault in N. Just looking at the distribution of magnitude 7 and greater quakes since instrumental records began (~1900), today’s M7.8 event is by far the largest quake ever recorded in this region. It has the same magnitude as one that killed about 30,000 people in December 1939 in northeast Turkey, tweeted Stephan Hicks, a researcher in seismology at the Imperial College London. According to experts, the quake is the joint largest on record (since roughly 1900) in Turkey. ![]() #deprem /YDc8DH9lbnĪ magnitude of 7.8 on the Moment Magnitude scale is indeed really strong. In #Sanliurfa the moment a building collapsed recorded by mobile phone hours after 7.8 #earthquake hits Turkey. Videos of buildings being razed to dust have been circulating on social media. “I have never felt anything like it in the 40 years I’ve lived”, Erdem, a resident of the Turkish city of Gaziantep, near the quake’s epicentre, told Reuters. ![]() See the Magnitude Types Table (below)for a summary of types, magnitude ranges, distance ranges, equations, and a brief description of each. ![]() Then, Moment Magnitude (M W) 2/3 log 10 (M O) - 9.1. Many survivors have claimed that this is the strongest quake they have felt in their lives. Measurements on the moment magnitude scale are determined using a complex mathematical formula to convert motion recorded with a seismometer into a magnitude. Thus, stronger rock material, or a larger area, or more movement in an earthquake will all contribute to produce a larger magnitude. ![]()
