  • Product Description
 

Revision with unchanged content. Discrimination between earthquakes and chemical explosions is a significant problem facing many regional seismic networks around the world. Both earthquakes and chemical explosions are sources of elastic waves; therefore, both are recorded by seismic networks. In this study various types of Pg/Sg amplitude phase ratios are explored as discriminants to distinguish between earthquakes and explosions. Amplitude information from 237 earthquakes (1.5>mb>4.9, 10>?>916 km) and 247 explosions (1.4>mb>3.9, 6>?>752 km) recorded by short period analog seismometers in Eastern Russia were used to calculate amplitude phase ratios of five different types. These ampli­tude ratios were analyzed separately in two regions: the Yakutia and Maga­dan regions of Eastern Russia. It was found a tendency of chemical explosions to have higher values than earthquakes for all types of amplitude ratios stu­died. The best earthquake-explosion discriminants found for both regions allow for the classification of 86-92% of the ratios as being either earth­quakes or explosions. This book is addressed to geoscientists, particularly seis­mologists and geophysicists interested in the field of seismic signal iden­tification.
