The Davsha cluster is named for the town of Davsha on the eastern shore
of Lake Baykal in eastern Russia. The earthquakes are mainly on the
eastern shore of the northern third of the lake. The number of seismic
stations in the area is not large but they are well situated to provide
robust locations and the ISC contains a large dataset of the seismicity,
upwards of 1000 events whose locations could be calibrated. The cluster
is composed of two classes of events selected from that large dataset:
1) those with the closest station coverage for depth control and good
azimuthal coverage, and 2) those with the best teleseismic datasets. All
events have depth control. Many of the larger events have depth
constraint from teleseismic depth phases that agrees well with the depth
inferred from near-source and local-distance readings.
