Document Summary

When a fault ruptures deep in the lithosphere, the energy is released mainly by ____________. Answer: p-waves that dissipate perpendicularly (at a 90 angle) from the fault plane, s-waves that dissipate perpendicularly (at a 90 angle) from the fault plane, raleigh waves that dissipate away. 0% from the fault plane: both p-waves and s-waves that dissipate in all directions away from the fault plane, p-waves, s-waves and raleigh waves that dissipate in all directions away from the fault plane. Answer: only p and s waves, only rayleigh and s waves, only rayleigh and love waves, only p, s, and rayleigh waves, all four wave types. Value: seismic energy release per square meter, moment magnitude, maximum ground acceleration, felt intensity of shaking, and damage 100, seismic moment rate. Based on the map of sw british columbia below, we can conclude that earthquake intensity in richmond is likely higher than that in vancouver because_______. Student response: the majority of buildings in.
