Source: Annenberg/CPB Resources - Earth Revealed - 16. Mass Wasting
Keywords: "mass wasting", "geologic hazard", creep, soil, slump, earthflow, bedrock, "Portuguese Bend", "Point Fermin", landslide

Our transcription: But that is not always the case.
Some people either don't know the facts about mass wasting or simply choose to ignore them and build anyway, and as we've seen, mass wasting can be a problem of major proportions no matter what form it takes.
Creep, for example, the continuous downslope movement of soil often proceeds too slowly to be detected until the damage has been done.
Slump and earthflows often move large amounts of soft or easily weathered bedrock in slow intermittent fashion over a long period of time.
Damage in coastal areas is frequently very serious.
At Portuguese Bend just west of Point Fermin what began as a slump evolved into a faster moving landsliding event that is an even more serious form of mass wasting.
As residents in the area have learned, the impact of landslides on property can be devastating.
