1EARTHQUAKE PREPERADNESS
- RECENT EARTHQUAKES LAST 8 30 DAYS
2WHAT ARE EARTHQUAKES
- Earthquakes, also called temblors, can be so
tremendously destructive, its hard to imagine
they occur by the thousands every day around the
world, usually in the form of small tremors.
3HOW ARE EQS MEASURED?
- Scientists assign a magnitude rating to
earthquakes based on the strength and duration of
their seismic waves. A quake measuring 3 to 5 is
considered minor or light 5 to 7 is moderate to
strong 7 to 8 is major and 8 or more is great. - On average, a magnitude 8 quake strikes somewhere
every year and some 10,000 people die in
earthquakes annually. Collapsing buildings claim
by far the majority of lives, but the destruction
is often compounded by mud slides, fires, floods,
or tsunamis. Smaller temblors that usually occur
in the days following a large earthquake can
complicate rescue efforts and cause further death
and destruction.
4Earthquake Safety Tips Keeping Safe
- Earthquakes are a common occurrence, rumbling
below Earth's surface thousands of times every
day. But major earthquakes are less common. Here
are some things to do to prepare for an
earthquake and what to do once the ground starts
shaking. - Safety Tips
- Have an earthquake readiness plan.
- Consult a professional to learn how to make your
home sturdier, such as bolting bookcases to wall
studs, installing strong latches on cupboards,
and strapping the water heater to wall studs. - Locate a place in each room of the house that you
can go to in case of an earthquake. It should be
a spot where nothing is likely to fall on you. - Keep a supply of canned food, an up-to-date first
aid kit, 3 gallons (11.4 liters) of water per
person, dust masks and goggles, and a working
battery-operated radio and flashlights. - Know how to turn off your gas and water mains.
- If Shaking Begins
- Drop down take cover under a desk or table and
hold on. - Stay indoors until the shaking stops and you're
sure it's safe to exit. - Stay away from bookcases or furniture that can
fall on you. - Stay away from windows. In a high-rise building,
expect the fire alarms and sprinklers to go off
during a quake. - If you are in bed, hold on and stay there,
protecting your head with a pillow. - If you are outdoors, find a clear spot away from
buildings, trees, and power lines. Drop to the
ground. - If you are in a car, slow down and drive to a
clear place. Stay in the car until the shaking
stops.

6Q During an EQ should you head for the doorway?
- 1 Only if you live in an old, unreinforced adobe
house. In modern homes doorways are no stronger
than any other parts of the house and usually
have doors that will swing and can injure you.
YOU ARE SAFER PRACTICING THE DUCK, COVER, AND
HOLD under a sturdy piece of furniture.
7Q What emergency supplies do I need?
- 2
- Fire extinguisher
- Adequate supplies of medications that you or
family members are taking - Crescent and pipe wrenches to turn off gas and
water supplies - First-aid kit and handbook
- Flashlights with extra bulbs and batteries
- Portable radio with extra batteries
- Water for each family member for at least two
weeks (allow at least 1 gallon per person per
day) and purification tablets or chlorine bleach
to purify drinking water from other sources - Canned and package foods, enough for several days
(72 hours) and MECHANICAL can opener. Extra food
for pets if necessary - Camp stove or barbecue to cook on outdoors (store
fuel out of the reach of children) - Waterproof, heavy-duty plastic bags for waste
disposal.
8Other items you may wish to include
- gloves, outdoor/winter clothing waterproof
matches and candles- but don't use them if there
are gas leaks or spilled flammable liquids
money, including coins (25 cents) for telephones,
because banks and credit cards may not be
usable a sleeping bag for each member of
your family garbage bags a portable
toilet rope, heavy tape a crowbar or
pry bar a gasoline generator and a rated
extension cord earthquake buddies for
children (eg stuffed animal, doll game)
evacuation pack for each person /vehicle pack for
each vehicle
9PREPARING YOUR HOME
- Secure top-heavy furniture (eg shelving units)
to prevent tipping. Keep heavy items on lower
shelves. - Fix mirrors and other hanging objects so they
won't fall of hooks. - Locate beds away from chimneys, windows, heavy
pictures, etc. Closed curtains will help keep
broken window glass off nearby occupied beds. - Put anti-skid pads (eg Velcro) under TVs, VCRs,
computers and small appliances. - Store valuable documents and special small
keepsakes in a fire-resistant place. - Keep sturdy shoes and outdoor clothing handy.
- Tie down your water heater and other appliances
that could break gas or water lines if they
topple.
10Q How can I plan ahead for an EQ?
- 3
- Make sure each member of your family knows what
to do no matter where they are when EQs occur - Establish a mtg place where you can all reunite
afterward - Find out about EQ plans developed by children's
school or day care - Remember transportation may be disrupted, keep
some emergency supplies--food, liquids, and
comfortable shoes, for example--at work - KNOW where you gas, electric and water main
shutoffs are and how to turn them off if there is
a leak or electrical short. Make sure older
members of the family can shut off utilities - LOCATE your nearest fire and police stations and
emergency medical facility - TALK to your neighbors--how could they help you,
or you them after an EQ - TAKE Red Cross First Aid and CPR Training Course.
Train members of your family to use fire
extinguishers. - Make an appointment now with your insurance
broker to talk about your earthquake insurance.
Check your coverage... it will affect your loss
and financial ability to recover after an
earthquake - Talk to your children about what to do if they're
at home, at school, if the quake separates your
family. Become familiar with the school's
earthquake plan. - Arrange an out-of-the-area contact. Each family
member should carry the contact phone number and
address. Have an alternative family rendezvous if
you can't get home.
11Q What should I do during an EQ?
- 4
- If you are INDOORS--STAY THERE! (Get under a desk
or table and hang on to it, or move into a
hallway or get against an inside wall. STAY CLEAR
of windows, fireplaces, and heavy furniture or
appliances. GET OUT of the kitchen, which is a
dangerous place (things can fall on you). DON'T
run downstairs or rush outside while the bldg is
shaking or while there is danger of falling and
hurting yourself or being hit by falling glass or
debris. - If you are OUTSIDE-- get into the OPEN, away from
bldgs, power lines, chimneys, and anything else
that might fall on you. - If you are DRIVING--stop, but carefully. Move
your car as far out of traffic as possible. DO
NOT stop on or under a bridge or overpass or
under trees, light posts, power lines, or signs.
STAY INSIDE your car until the shaking stops.
When you RESUME driving watch for breaks in the
pavement, fallen rocks, and bumps in the road at
bridge approaches. - If you are in a MOUNTAINOUS AREA--watch out for
falling rock, landslides, trees, and other debris
that could be loosened by quakes.
12Q Things NOT to do during an EQ?
- 5
- DO NOT turn on the gas again if you turned it
off let the gas company do it - DO NOT use matches, lighters, camp stoves or
barbecues, electrical equipment, appliances UNTIL
you are sure there are no gas leaks. They may
create a spark that could ignite leaking gas and
cause an explosion and fire - DO NOT use your telephone, EXCEPT for a medical
or fire emergency. You could tie up the lines
needed for emergency response. If the phone
doesn't work send someone for help - DO NOT expect firefighters, police or paramedics
to help you. They may not be available.
13Q What can I expect in my house when an EQ
occurs? How do I identify it? What can be done?
- 6 The contents of your home may be damaged and
can be dangerous - Shaking can make light fixtures fall,
refrigerators and other large items move across
the floor, and bookcases and television sets
topple over. IDENTIFY Look around your house for
things that could fall or move - Ask yourself if your cupboard doors fly open
(allowing dishes to shatter on the floor) - Is TV and stereo fastened down and are shelves
fastened to wall? Do you have hanging plants or
light fixtures that might fall? Is there a heavy
picture or mirror on the wall over your bed? - WHAT CAN BE DONE You can install door latches,
braces and fasteners to fix most of these hazards
yourself.
14Q What do I do after an earthquake?
- A
- WEAR STURDY SHOES to avoid injury from broken
glass and debris. Expect aftershocks - CHECK FOR INJURIES (if a person is bleeding, put
direct pressure on the wound, use clean gauze or
cloth if available If a person is not breathing
administer CPR DO NOT attempt to move seriously
injured persons unless they are in further danger
of injury COVER injured persons with blankets to
keep warm SEEK medical help for serious injuries
- CHECK FOR HAZARDS (Fire hazards--put out fires in
your home or neighborhood immediately, call for
help Gas leaks--shut off main gas valve ONLY if
you suspect a leak because of broken pipes or
odor Damaged electrical wiring--Shut off power
at the control box if there is any danger to
house wiring Downed or damaged utility lines--do
not touch downed power lines or any objects in
contact with them SPILLS--clean up any spilled
medicines, drugs, or other harmful materials such
as bleach, lye, gas DOWNED OR DAMAGED
CHIMNEYS--Approach with caution--don't use
damaged chimney (it could start fire or let
poisonous gases into your house FALLEN
ITEMS--beware of items tumbling off shelves when
you open doors of closets and cupboards CHECK
FOOD AND WATER SUPPLIES--Do not eat or drink
anything from open containers near shattered
glass If power is off, plan meals to use up
foods that will spoil quickly or frozen foods
(food in the freezer should be good for at least
a couple of days Don't light your kitchen stove
if you suspect a gas leak USE BBQ or camp
stoves, outdoors only for emergency cooking If
your water is off you can drink supplies from
water heaters, melted ice cubes or canned
vegetables (AVOID drinking water from swimming
pools or especially spas--it may have too many
chemicals in it to be safe.)
15WHERE DO MOST EQ OCCUR
- Some 80 percent of all the planet's earthquakes
occur along the rim of the Pacific Ocean, called
the "Ring of Fire" because of the preponderance
of volcanic activity there as well. Most
earthquakes occur at fault zones, where tectonic
platesgiant rock slabs that make up the Earth's
upper layercollide or slide against each other.
These impacts are usually gradual and
unnoticeable on the surface however, immense
stress can build up between plates. When this
stress is released quickly, it sends massive
vibrations, called seismic waves, often hundreds
of miles through the rock and up to the surface.
Other quakes can occur far from faults zones when
plates are stretched or squeezed.
16Q What are the steps to EQ safety/awareness?
- A
- Estimate what EQ of what size are likely to occur
(geology) - Given the EQ size we then estimate what the
shaking will be (seismology) - Given the shaking we estimate the response of
different types of buildings (EQ engineering).
Only with all these steps can we take steps as
society to enact bldg. codes and retrofitting
programs to make our community safer.
17EARTHQUAKE RATTLES NERVES
- By Raphael Satter, The Associated Press
- LONDON - Experts say there is nothing unusual
about the latest spate of earthquakes in Haiti,
Chile and now Turkey, but their devastation
illustrates how growing construction along the
world's fault lines can lead to massive
casualties. - Seismologists say that although one powerful
quake can conceivably raise the risk for others
elsewhere, the recent string of quakes is
probably just coincidence. - Bob Holdsworth, an expert in tectonics at Durham
University, said Monday that "I can definitely
tell you that the world is not coming to an end."
- Bernard Doft, the seismologist for the Royal
Netherlands Meteorological Institute, says there
is no direct connection between the lethal quakes
that have struck Haiti, Chile and Turkey. - "These events are too far apart to be of direct
influence to each other," he said. - Although the Haitian quake occurred along a fault
that had seen no major event for 250 years, both
Chile and Turkey are prone to devastating quakes.
- "It was by accident that it happened at
approximately the same time," he said. - Monday's quake in Turkey had a 6.0 magnitude. On
average, there are 134 earthquakes a year that
have a magnitude between a 6.0 and 6.9, according
to the U.S. Geological Survey. This year is off
to a fast start with 40 so far - more than in
most years for that period of time. - But that's because the 8.8 quake in Chile
generated a large number of strong aftershocks,
and so many occurring this early in the year
skews the picture, said USGS seismologist Paul
Earle. - "Years that have large quakes are likely to be
higher in overall seismicity," Earle said. The
Chilean quake was the sixth strongest since 1900.

22OTHER EFFECTS OF EQS
- What is tsunami?
- Tsunami is a Japanese word with the English
translation, "harbor wave." The phenomenon we
call tsunami is a series of large waves of
extremely long wavelength and period usually
generated by a violent, impulsive undersea
disturbance or activity near the coast or in the
ocean. - Tsunamis can be generated when the sea floor
abruptly deforms and vertically displaces the
overlying water. Tectonic earthquakes are a
particular kind of earthquakes that are
associated with the earth's crustal deformation
when these earthquakes occur beneath the sea, the
water above the deformed area is displaced from
its equilibrium position. Waves are formed as the
displaced water mass, which acts under the
influence of gravity, attempts to regain its
equilibrium. When large areas of the sea floor
elevate or subside, a tsunami can be created.
23WHAT CAN BE DONE?
- Loss of life can be avoided through emergency
planning, education, and the construction of
buildings that sway rather than break under the
stress of an earthquake. - You can't prevent an earthquake. But you can
be prepared to avoid injury be prepared to
minimize damage to your home be prepared to
survive afterwards for at least 72 hours without
help.
24Your emergency supplies
- Be prepared to be on your own without help for 72
hours or more--- at home, in your car, at work.
Assemble these emergency supplies and keep them
in your emergency kit, stored in a secure place,
ideally accessible from outside
25WANT TO DO MORE?
- Now that you've taken care of the basics, you may
want to take additional steps to protect yourself
and others. Remember- you may be on your own for
72 hours or more. What you do will depend on your
particular situation. You could - Volunteer any special skills you have to your
Municipal Emergency Program Co-ordinator. - Involve your neighborhood in earthquake
preparedness... by helping elderly neighbors to
prepare their homes, by agreeing to check on each
other after an earthquake and to care for pets. - Plan for special needs for infants, the elderly
and the handicapped, in case pharmacies and other
stores are closed for several days. If your
family includes people with impaired mobility,
hearing or sight, see the list of useful contacts
at the end of this document to get special
preparedness details for them. If you depend on
electric power for life support or a wheelchair,
you may wish to have a small generator with extra
fuel handy. - Review the supplies that you would need to be
self-sufficient and comfortable for at least 72
hours. In addition to basics, there are many
items such as plastic sheets or dust masks that
you may want to acquire, or perhaps games and
comfort items for children. Sources of advice are
shown below.Planning for earthquakes will also
help prepare you for many other emergencies. - Be prepared, not scared.
