Abstract
The Central Weather Bureau Seismic Network (CWBSN) is maintained
under the high-gain and limited recording range for monitoring Taiwan regional
earthquakes. For large earthquakes, near source ground shakings will be over
the recording range of this system. It has a great effect on large events
magnitude determination and hypocenter location. (system can not pick near
source S wave arrivals). However, when a large event occurred, the Taiwan
Instrument Strong Motion Program (TSMIP) accelerometers will be triggered
and record it. These records can be used for enhancing large events
monitoring. For this above reason, we used the CWBSN and TSMIP records to
determine the 3D velocity structures and to improve the precision of
earthquakes location.
