Combined Maps

These combined maps were produced by combining RotD50 results from Study 15.4 (LA, CVM-S4.26) and Study 17.3 (Central CA, CCA-06). In the small overlap region between the CCA and LA CyberShake regions, values at sites in both studies were averaged with equal weight. Additionally, these maps use the Vs30 only basemap (not Z1.0 or Z2.5).

Ellipse Coldspot

The 'coldspot' (lower hazard) which appears around (35.2, -119.5) is due to the velocity model, likely an artifact from CVM-S4's rule-based approach. Below is a plot of Z2.5 around the hotspot:
