Data Services Products: EMC-IFM1_S_2020 Ps-P crustal tomography relative S wave model for Cleveland Volcano

Summary

IFM1_S_2020 uses Moho-generated Ps-P delay times derived from receiver functions recorded at 11 seismic stations around Cleveland Volcano, Alaska in the Aleutian arc. These are inverted for a local S wave tomography model that produces relative variations in S wave velocities. These are a proxy for relative variations in Vp/Vs.

Depth Coverage surface to 50 km below sea level
 
Area Cleveland Volcano, Alaska (latitude: 52.28° to 53.44° and longitude is -170.83° to -168.93° East)
 
Data Set Description This model uses 229 Ps-P delay times recorded using receiver function analysis at 11 seismic stations. These stations come from temporary IFM seismic network (code Y2) and the permanent AVO network (AV), all available at the IRIS seismic data repository.
