An ML 5.0 earthquake releases about the same seismic energy as a 10,000 tonne equivalent nuclear blast, such as that used at Hiroshima. The Richter magnitude scale can only be used when seismographs are within 600 km of the earthquake. For greater distances, other magnitude scales have been defined.
When compared to a 4.0 earthquake, a 5.0 earthquake has a shaking amplitude that is 10 times larger and an energy output that is 31.6 times greater.
A nuclear detonation like the one used at Hiroshima that has an equivalent seismic energy of 10,000 tonnes is equivalent to an ML 5.0 earthquake. Seismographs must be 600 km or closer from the earthquake in order to use the Richter scale. Other magnitude scales have been created for longer distances.
