If you remain at home, move to a part of the house farthest away from the source of the landslide or debris flows, such as an upper floor, but keep an escape route open should it become necessary to leave the house. Be especially alert when driving . Embankments along roadsides are particularly susceptible to landslides. Watch the road for collapsed pavement, mud, fallen rocks , and other indications of possible landslides or debris flows. After Intense Storms Keep looking for signs that the land is moving.
Landslides can occur weeks or months after intense storms.
If a very detailed site analysis is desired, contract with a private consulting company that specializes in earth movement. Such companies would likely be those specializing in geotechnical engineering, structural engineering, or civil engineering. Your local, state or county geologist can usually advise you as to the best kind of professional to contact.
