Slide
Mountain, Nevada-Boulders partially bury
a house from a debris flow triggered by rapid
snowmelt in late May 1983. The rapidly moving
debris flow emerged from a canyon and killed
one person, injured several others, destroyed
or severely damaged five homes, and buried
a highway. Photograph

Warning
Signs
|
|
| |
- Changes
occur in your landscape such as patterns
of storm-water drainage on slopes (especially
the places where runoff water converges),
land movement, small slides, flows, or
progressively leaning trees.
|
|
| |
- Doors
or windows stick or jam for the first time.
|
|
| |
- New
cracks appear in plaster, tile, brick,
or foundations.
|
|
| |
- Slowly
developing, widening cracks appear on the
ground or on paved areas such as streets
or driveways.
|
|
| |
- Underground
utility lines break.
|
|
| |
- Bulging
ground appears at the base of a slope.
|
|
| |
- Water
breaks through the ground surface in new
locations.
|
|
| |
- Fences,
retaining walls, utility poles, or trees
tilt or move.
|
|
| |
- A
faint rumbling sound that increases in
volume is noticeable as the landslide nears.
|
|
| |
- The
ground slopes downward in one direction
and may begin shifting in that direction
under your feet.
|
|
| |
- Unusual
sounds, such as trees cracking or boulders
knocking together, might indicate moving
debris.
|
|
| |
- Collapsed
pavement, mud, fallen rocks, and other
indications of possible debris flow can
be seen when driving (embankments along
roadsides are particularly susceptible
to landslides).
