Radar Structure of Earthquake-Induced, Coastal Landslides in Anchorage, Alaska

Figure 6

Raw data from CMP survey and a velocity stack section.

(A) Raw data from CMP survey at Government Hill. Travel times from the reflectors vary hyperbolically as the antenna separation increases, whereas direct arrivals through the air and ground vary in a linear fashion. (B) Velocity stack section calculated from CM P data in (A). An average velocity of 0. 12 m/ns (arrow) is estimated for signals traveling between the surface and the reflection at 200 nsec (dashed line). ns, nsec.
