SHAKE,
RATTLE AND ROLL….
APRIL IS CALIFORNIA
EARTHQUAKE PREPAREDNESS MONTH!
We tend to think of our earth
as ‘solid ground,’ but its crust is really a series
of plates edged again each other, the whole resting like a cracked
egg shell on a liquid core of molten and semi-molten magma. From
the beginning of time great forces and pressures within the earth
have constantly broken, folded, and moved these plates about.
A large earthquake is one of
nature’s most devastating phenomena. The energy released by
an earthquake of 8.5 magnitude on the Richter scale is equivalent
to 12,000 times the energy released by the Hiroshima atomic bomb.
Several million earthquakes occur
annually throughout the world. They range from barely perceptible
tremors to catastrophic shocks. In California, where the ground
is always moving, we average one earthquake every 3 minutes. These
quakes are usually so small, and Californians are so used to this
continual ground vibration, that we barely notice them, if at all.
In addition to damage to buildings
from ground shake, earthquakes can cause failures in utility services
by rupturing power grids, overhead wires, and pipelines. With interruption
of power, communications and water services, emergency response
is slowed tremendously.
The loss of life in the United
States has been relatively light, considering the number of destructive
earthquakes that have occurred. This is explained partially by better
than usual construction practices, but more by lucky circumstances,
such as people being in relatively safe places at the time of an
earthquake.
The actual earth movement of
an earthquake is seldom a direct cause of death or injury. However,
this movement causes the collapse of buildings and other structures.
Most casualties result from (1) falling bricks and plaster; (2)
splintering glass; (3) toppling furniture, collapsing walls, falling
pictures and mirrors; (4) rock slides on mountains and hillsides;
(5) fallen power lines; (6) sea waves generated by earthquakes;
and (7) fire caused by broken gas lines and spillage of gasoline
and other flammables.
Although we cannot prevent earthquakes
from happening, and we can’t yet accurately predict when another
earthquake will hit, we know that preparation before an earthquake
can save lives and help protect property.
PEOPLE DON’T PLAN TO FAIL…
THEY FAIL TO PLAN!
Much of earthquake preparedness
is common sense and good housekeeping. It doesn’t take a lot
of money or extraordinary measures to get ready for the next ‘big’
one. As we say in California, it’s ‘when’, not
‘if’!
Take a few minutes this month
to help yourself and your family.
Next month—why not visit
the Lawndale Community Health & Safety Fiesta at the Civic Center
Plaza on May 7 from 11:00 a.m. to 4:00 p.m. for more ideas and information
on safety and preparedness.
BE AWARE – PREPARE!
