Discrimination between natural earthquakes and nuclear explosions using the Aswan Seismic Network

R. M. Kebeasy, A. I. Hussein, S. A. Dahy


There are many seismological differences between earthquake and nuclear explosions, but not all of them are observable at large distances or are applicable to every earthquake and explosion. Several discriminations have been checked using the Aswan Seismic Network (ASN) data. Data of 66 earthquakes and 42 presumed underground explosions which occurred in different regions of China, the U.S.S.R., India, Iran, Turkey and recorded at ASN were collected. All data were selected from the NEIC catalogue and EDR reports. It was found that mb: Msas well as mb(1 Hz): mb (2 Hz) work well for events with mb larger than 4.0 from data observed at ASN and obtained from the NEIC catalogue.
