>> BAY AREA EARTHQUAKE TRACKER When a big quake hits, nearly everything we rely on — gas, electricity, water, transportation, medical assistance and fire protection — may be interrupted. You should be ready to take care of yourself, your family, your neighbors and co-workers. Start by developing your own emergency plan. Involve the whole family so they'll know where emergency supplies are kept and what safety precautions to follow. Practice runs will make sure that everyone knows what to do. Follow these steps: Always have on hand:
Know the location of your gas and electric service. Turn off the gas if you smell gas, turn off the electricity if house wires are damaged. Remember, only a qualified service person should turn gas service back on. Read instructions for fire extinguishers. Know how to use them before you need them. Secure cabinets by installing child-proof latches to keep them from flying open and their contents from falling on someone. Anchor water heaters to wall studs with metal straps. This will prevent them from tipping over and breaking gas lines. Also, the water in the tank can be saved for drinking. Source: PGE.com WHAT TO DO DURING AN EARTHQUAKE Drop, cover, and hold on! Move only a few steps to a nearby safe place. Most injured persons in earthquakes move more than five feet during the shaking. It is very dangerous to try to leave a building during an earthquake because objects can fall on you. Many fatalities occur when people run outside of buildings, only to be killed by falling debris from collapsing walls. In U.S. buildings, you are safer to stay where you are. If you are in bed, hold on and stay there, protecting your head with a pillow. You are less likely to be injured staying where you are. Broken glass on the floor has caused injury to those who have rolled to the floor or tried to get to doorways. If you are outdoors, find a clear spot away from buildings, trees, streetlights, and power lines. Drop to the ground and stay there until the shaking stops. Injuries can occur from falling trees, street-lights and power lines, or building debris. If you are in a vehicle, pull over to a clear location, stop and stay there with your seatbelt fastened until the shaking has stopped. Trees, power lines, poles, street signs, and other overhead items may fall during earthquakes. Stopping will help reduce your risk, and a hard-topped vehicle will help protect you from flying or falling objects. Once the shaking has stopped, proceed with caution. Avoid bridges or ramps that might have been damaged by the quake. Stay indoors until the shaking stops and you're sure it's safe to exit. More injuries happen when people move during the shaking of an earthquake. After the shaking has stopped, if you go outside, move quickly away from the building to prevent injury from falling debris. Stay away from windows. Windows can shatter with such force that you can be injured several feet away. In a high-rise building, expect the fire alarms and sprinklers to go off during a quake. Earthquakes frequently cause fire alarm and fire sprinkler systems to go off even if there is no fire. Check for and extinguish small fires, and, if exiting, use the stairs. If you are in a coastal area, move to higher ground. Tsunamis are often created by earthquakes. If you are in a mountainous area or near unstable slopes or cliffs, be alert for falling rocks and other debris that could be loosened by the earthquake. Landslides commonly happen after earthquakes. Source: Federal Emergency Management Agency WHAT TO DO AFTER AN EARTHQUAKE Check yourself for injuries. Often people tend to others without checking their own injuries. You will be better able to care for others if you are not injured or if you have received first aid for your injuries. Protect yourself from further danger by putting on long pants, a long-sleeved shirt, sturdy shoes, and work gloves. This will protect your from further injury by broken objects. After you have taken care of yourself, help injured or trapped persons. If you have it in your area, call 9-1-1, then give first aid when appropriate. Don't try to move seriously injured people unless they are in immediate danger of further injury. Look for and extinguish small fires. Eliminate fire hazards. Putting out small fires quickly, using available resources, will prevent them from spreading. Fire is the most common hazard following earthquakes. Fires followed the San Francisco earthquake of 1906 for three days, creating more damage than the earthquake. Leave the gas on at the main valve, unless you smell gas or think it's leaking. It may be weeks or months before professionals can turn gas back on using the correct procedures. Explosions have caused injury and death when homeowners have improperly turned their gas back on by themselves. Clean up spilled medicines, bleaches, gasoline, or other flammable liquids immediately. Avoid the hazard of a chemical emergency. Open closet and cabinet doors cautiously. Contents may have shifted during the shaking of an earthquake and could fall, creating further damage or injury. Inspect your home for damage. Get everyone out if your home is unsafe. Aftershocks following earthquakes can cause further damage to unstable buildings. If your home has experienced damage, get out before aftershocks happen. Help neighbors who may require special assistance. Elderly people and people with disabilities may require additional assistance. People who care for them or who have large families may need additional assistance in emergency situations. Listen to a portable, battery-operated radio (or television) for updated emergency information and instructions. If the electricity is out, this may be your main source of information. Local radio and local officials provide the most appropriate advice for your particular situation. Expect aftershocks. Each time you feel one, drop, cover, and hold on! Aftershocks frequently occur minutes, days, weeks, and even months following an earthquake. Watch out for fallen power lines or broken gas lines, and stay out of damaged areas. Hazards caused by earthquakes are often difficult to see, and you could be easily injured. Stay out of damaged buildings. If you are away from home, return only when authorities say it is safe. Damaged buildings may be destroyed by aftershocks following the main quake. Use battery-powered lanterns or flashlights to inspect your home. Kerosene lanterns, torches, candles, and matches may tip over or ignite flammables inside. Inspect the entire length of chimneys carefully for damage. Unnoticed damage could lead to fire or injury from falling debris during an aftershock. Cracks in chimneys can be the cause of a fire years later. Take pictures of the damage, both to the house and its contents, for insurance claims. Avoid smoking inside buildings. Smoking in confined areas can cause fires. When entering buildings, use extreme caution. Building damage may have occurred where you least expect it. Carefully watch every step you take. Examine walls, floor, doors, staircases, and windows to make sure that the building is not in danger of collapsing. Check for gas leaks. If you smell gas or hear a blowing or hissing noise, open a window and quickly leave the building. Turn off the gas, using the outside main valve if you can, and call the gas company from a neighbor's home. If you turn off the gas for any reason, it must be turned back on by a professional. Look for electrical system damage. If you see sparks or broken or frayed wires, or if you smell burning insulation, turn off the electricity at the main fuse box or circuit breaker. If you have to step in water to get to the fuse box or circuit breaker, call an electrician first for advice. Check for sewage and water line damage. If you suspect sewage lines are damaged, avoid using the toilets and call a plumber. If water pipes are damaged, contact the water company and avoid using water from the tap. You can obtain safe water from undamaged water heaters or by melting ice cubes. Watch for loose plaster, drywall, and ceilings that could fall. Use the telephone only to report life-threatening emergencies. Telephone lines are frequently overwhelmed in disaster situations. They need to be clear for emergency calls to get through. Watch animals closely. Leash dogs and place them in a fenced yard. The behavior of pets may change dramatically after an earthquake. Normally quiet and friendly cats and dogs may become aggressive or defensive. Source: Federal Emergency Management Agency Bolt bookcases, china cabinets, and other tall furniture to wall studs. Brace or anchor high or top-heavy objects. During an earthquake, these items can fall over, causing damage or injury. Secure items that might fall (televisions, books, computers, etc.). Falling items can cause damage or injury. Install strong latches or bolts on cabinets. The contents of cabinets can shift during the shaking of an earthquake. Latches will prevent cabinets from flying open and contents from falling out. Move large or heavy objects and fragile items (glass or china) to lower shelves. There will be less damage and less chance of injury if these items are on lower shelves. Store breakable items such as bottled foods, glass, and china in low, closed cabinets with latches. Latches will help keep contents of cabinets inside. Store weed killers, pesticides, and flammable products securely in closed cabinets with latches, on bottom shelves. Chemical products will be less likely to create hazardous situations from lower, confined locations. Hang heavy items, such as pictures and mirrors, away from beds, couches, and anywhere people sit. Earthquakes can knock things off walls, causing damage or injury. Brace overhead light fixtures. During earthquakes, overhead light fixtures are the most common items to fall, causing damage or injury. Strap the water heater to wall studs. The water heater may be your best source of drinkable water following an earthquake. Protect it from damage and leaks. Bolt down any gas appliances. After an earthquake, broken gas lines frequently create fire hazards. Install flexible pipe fittings to avoid gas or water leaks. Flexible fittings will be less likely to break. Repair any deep cracks in ceilings or foundations. Get expert advice if there are signs of structural defects. Earthquakes can turn cracks into ruptures and make smaller problems bigger. Check to see if your house is bolted to its foundation. Homes bolted to their foundations are less likely to be severely damaged during earthquakes. Homes that are not bolted have been known to slide off their foundations, and many have been destroyed because they are uninhabitable. Consider having your building evaluated by a professional structural design engineer. Ask about home repair and strengthening tips for exterior features, such as porches, front and back decks, sliding glass doors, canopies, carports, and garage doors. Learn about additional ways you can protect your home. A professional can give you advice on how to reduce potential damage. Follow local seismic building standards and safe land use codes that regulate land use along fault lines. Some municipalities, counties, and states have enacted codes and standards to protect property and occupants. Learn about your area's codes before construction. Source: Federal Emergency Management Agency Get two pieces of 22-gauge metal earthquake straps about 10 feet long and 1-1/2 inch wide; four 2-1/2 inch by 5/16 inch lag bolts; drill and 3/16 inch drill bit; a wrench. Place one earthquake strap about a foot from the top of the water heater, over the insulation blanket. If possible, completely encircle the tank with the strap. This helps prevent the tank from swaying during an earthquake. Never place straps over the controls or over any pipes that run along the outside of the tank. Use your drill to make pilot holes for the lag bolts. Then thread the lag bolts through each end of the strap and screw them into the wall studs on each side of the tank. Make sure the strap holds the water heater snugly. Repeat the process for the bottom strap, installing it about 18 inches from the bottom of the tank. If there is a space between the tank and the wall, install spacers to prevent the tank from shifting backwards. Spacers can be cut to fit from drywall or other noncombustible materials. Attach them to the wall behind the tank. Be sure a flexible pipe is used to connect the gas supply to the heater. If not, call a plumbing or heating contractor. Source: PGE.com In an emergency, your gas can be turned off at the main shut-off valve next to your gas meter. Using a wrench or other suitable tool, give the valve a quarter turn in either direction; the valve is closed when the tang (the part you put the wrench on) is crosswise to the pipe. Once your gas has been shut off, do not try to turn it back on. Only a qualified service person with special training and equipment can do this safely. Call PG&E; and we will send someone out to do it for you. Source: PGE.com QUAKE & FIRE SAFETY FACT SHEET A wide range of natural disasters occurs within the United States every year. Natural disasters can have a devastating effect on you and your home. The Federal Emergency Management Agency's U.S. Fire Administration encourages you to use the following safety tips to help protect yourself, your family and your home from the potential threat of fire during or after an earthquake. You can greatly reduce your chances of becoming a fire casualty by being able to identify potential hazards and following the outlined safety tips. Some types of fire related hazards present during and after an earthquake

And remember...
Source: Federal Emergency Management Agency Find safe places in every room of your home and your classroom. Look for safe places inside and outside of other buildings where you spend time. The shorter the distance you have to travel when the ground shakes, the safer you will be. Earthquakes can happen anytime and anywhere, so be prepared wherever you go. If you're indoors during an earthquake, drop, cover, and hold on. Get under a desk, table or bench. Hold on to one of the legs and cover your eyes. If there's no table or desk nearby, sit down against an interior wall. An interior wall is less likely to collapse than a wall on the outside shell of the building. Pick a safe place where things will not fall on you, away from windows, bookcases, or tall, heavy furniture. It is dangerous to run outside when an earthquake happens because bricks, roofing, and other materials may fall from buildings during and immediately following earthquakes, injuring persons near the buildings. Wait in your safe place until the shaking stops, then check to see if you are hurt. You will be better able to help others if you take care of yourself first, then check the people around you. Move carefully and watch out for things that have fallen or broken, creating hazards. Be ready for additional earthquakes called "aftershocks." Be on the lookout for fires. Fire is the most common earthquake-related hazard, due to broken gas lines, damaged electrical lines or appliances, and previously contained fires or sparks being released. If you must leave a building after the shaking stops, use the stairs, not the elevator. Earthquakes can cause fire alarms and fire sprinklers to go off. You will not be certain whether there is a real threat of fire. As a precaution, use the stairs. If you're outside in an earthquake, stay outside. Move away from buildings, trees, streetlights, and power lines. Crouch down and cover your head. Many injuries occur within 10 feet of the entrance to buildings. Bricks, roofing, and other materials can fall from buildings, injuring persons nearby. Trees, streetlights, and power lines may also fall, causing damage or injury. Source: Federal Emergency Management Agency Make arrangements for your pets as part of your household disaster planning. If you must evacuate your home, it's always best to take your pets with you. For health and space reasons, pets will not be allowed in public emergency shelters. If, as a last resort, you have to leave your pets behind, make sure you have a plan to ensure their care. Before the disaster Contact your local animal shelter, humane society, veterinarian or emergency management office for information on caring for pets in an emergency. Find out if there will be any shelters set-up to take pets in an emergency. Also, see if your veterinarian will accept your pet in an emergency. Decide on safe locations in your house where you could leave your pet in an emergency.
If your pet is on medication or a special diet, find out from your veterinarian what you should do in case you have to leave it alone for several days. Try and get an extra supply of medications.
Keep your pet's shots current and know where the records are. Most kennels require proof of current rabies and distemper vaccinations before accepting a pet. Contact motels and hotels in communities outside of your area and find out if they will accept pets in an emergency. When assembling emergency supplies for the household, include items for pets.
Trained Guide Dogs: In most states, trained guide dogs for the blind, hearing impaired or handicapped will be allowed to stay in emergency shelters with their owners. Check with local emergency management officials for more information. During the disaster Bring your pets inside immediately. Animals have instincts about severe weather changes and will often isolate themselves if they are afraid. Bringing them inside early can stop them from running away. Never leave a pet outside or tied up during a storm. If you evacuate and have to leave your pet at home, prepare a safe location for it.
If you evacuate and plan to take your pets, remember to bring your pet's medical records and medicines with your emergency supplies.
Birds: Birds must eat daily to survive. In an emergency, you may have to leave your birds behind. Talk with your veterinarian or local pet store about special food dispensers that regulate the amount of food a bird is given. Make sure that the bird is caged and the cage is covered by a thin cloth or sheet to provide security and filtered light. After If after a disaster you have to leave town, take your pets with you. Pets are unlikely to survive on their own. In the first few days after the disaster, leash your pets when they go outside. Always maintain close contact. Familiar scents and landmarks may be altered and your pet may become confused and lost. Also, snakes and other dangerous animals may be brought into the area with flood areas. Downed power lines are a hazard. The behavior of your pets may change after an emergency. Normally quiet and friendly pets may become aggressive or defensive. Watch animals closely. Leash dogs and place them in a fenced yard with access to shelter and water. Source: Federal Emergency Management Agency Like most earthquakes, the recent earthquake is expected to be followed by numerous aftershocks. Aftershocks are additional earthquakes that occur after the mainshock and in the same geographic area. Usually, aftershocks are smaller than the mainshock, but occasionally an aftershock may be strong enough to be felt widely throughout the area and may cause additional damage, particularly to structures already weakened in the mainshock. As a rule of thumb, aftershocks of magni- tude 5 and larger are considered potentially damaging. Aftershocks are most common immediately after the mainshock; their average number per day decreases rapidly as time passes. Aftershocks are most likely to be felt in the first few days after the mainshock, but may be felt weeks, months, or even years afterwards. In general, the larger the mainshock, the longer its aftershocks will be felt. Aftershocks tend to occur near the mainshock, but the exact geographic pattern of the aftershocks varies from earthquake to earthquake and is not predictable. The larger the mainshock, the larger the area of aftershocks. While there is no "hard" cutoff distance beyond which an earthquake is totally incapable of triggering an aftershock, the vast majority of aftershocks are located close to the mainshock. As a rule of thumb, a magnitude 6 mainshock may have aftershocks up to 10 to 20 miles away, while a magnitude 7 mainshock may have aftershocks as far as 30 to 50 miles away.
