Earthquake Scenario, how would you do if an earthquake happened today?
Find a safe spot in every room, click here to see examples?.
Move heavy objects and household chemicals from the top of the refrigerator or shelves. Keep your bleach products down low and away from your ammonia products so their bottles can't break and mix together creating chlorine gas.
Keep your garage doors closed to reduce the amount that your home is a soft structure?.
Practice drop cover today and hold to help overcome the tendency to want to get up and go, hold things up, or just sit there thinking about how odd it is that everything is moving. Make a plan on being a leader and encouraging others to secure themselves instead of leaving.
Earthquakes can happen at any time, in any weather--some countries are researching ways to get early notification, but because we don't have it here, it is better to always be as ready as possible for an earthquake to take place. It is always a good idea to sign up for notification services?
Earthquakes happen every day all over the world, even quite large ones. There are usually multiple earthquakes per day in our region, but most are too small to feel. You can see a real time map of earthquakes at the Pacific Northwest Seismic Network's website at: http://www.pnsn.org/recenteqs/latest.htm Click here to see more real time information sources.real time information On a yearly basis, 70 to 75 damaging earthquakes occur throughout the world. Estimates of losses from a future earthquake in the United States
approach $200 billion.
Earthquakes happen due to the movement of tectonic plates, or due to volcanic activity.
Past major earthquakes in our area have lasted 20 seconds or so, to over 4 minutes. You should expect after shocks that can last for a number of days after the earthquake.
Everybody needs to worry about earthquakes-but remember, for every problem there is a solution-many just require the willingness to sit and think, ask and write information down. Take a Saturday and make the contents of your house safe, we have links to handy guides to help with non structural fixes and how to make sure what is inside your house isn't out to get you. If it turns out that your house isn't structurally safe-it is really better to know it and start working on fixing it. You aren't in this alone.

What are earthquakes and what causes them?
An earthquake is a sudden, rapid shaking of the earth caused by the breaking and shifting of rock beneath the earth's surface. For hundreds of millions of years, the forces of plate tectonics have shaped the earth as the huge plates that form the surface move slowly over, under, past, and away from each other. Sometimes the movement is gradual. At other times, the plates are locked together, unable to release the accumulating energy as they bend or stretch. When the forces grow strong enough, the plates suddenly break free causing the ground to shake. Most earthquakes occur at the boundaries where two plates meet; however, some earthquakes occur in the middle of plates.
MSNBC Interactive: What causes earthquakes: http://www.msnbc.msn.com/id/7807001
Aftershocks are smaller earthquakes that follow the main shock and can cause further damage to weakened buildings. Aftershocks can occur in the first hours, days, weeks, or even months after the quake. Some earthquakes are actually foreshocks that precede a larger earthquake. Ground shaking from earthquakes can collapse buildings and bridges; disrupt gas, electric, and telephone service; and sometimes trigger landslides, avalanches, flash floods, fires, and huge, destructive, seismic sea waves called tsunamis. Buildings with foundations resting on unconsolidated landfill and other unstable soils are at increased risk of damage. Also, mobile homes and homes not attached to their foundations are at particular risk because they can be shaken off their foundations during an earthquake. When an earthquake occurs in a populated area, it may cause deaths and injuries and extensive property damage.
Much of the damage caused by earthquakes is predictable and preventable. We must all work together in our communities to apply our knowledge to enact and enforce up-to-date building codes, retrofit older unsafe buildings, and avoid building in hazardous areas, such as those prone to landslides. We must also look for and eliminate hazards at home, where our children spend their days, and where we work. And we must learn and practice what to do if an earthquake occurs.
Is your home safe to enter? How do you get financial assistance? How do you salvage your possessions? Fema: https://www.disasterhelp.gov/your-home.shtm
Fiction: During an earthquake, you should get into a doorway for protection.
Facts: In modern homes, doorways are no stronger than any other parts of the structure and usually have doors that will swing and can injure you. During an earthquake, you should get under a sturdy piece of furniture and hold on.
Fiction: During an earthquake, the earth cracks open and people, cars, and animals can fall into those cracks.
Facts: The earth does not crack open like the Grand Canyon. The earth moves and rumbles and, during that movement, small cracks can form. The usual displacements of the earth during an earthquake are caused by up-and-down movements, so shifts in the height of the soil are
more likely than chasm-like cracks.
Fiction: Animals can sense earthquakes and give advanced warning.
Facts: Animals may be able to sense the first low-frequency waves of an earthquake that occurs deep within the earth, but the damage-causing primary and secondary waves follow just seconds behind. Animals do not make good earthquake warning devices.
Fiction: Big earthquakes always happen in the early morning.
Facts: Several recent damaging earthquakes have occurred in the early morning, so many people believe that all big earthquakes happen then. In fact, earthquakes occur at all times of day. The 1933 Long Beach earthquake was at 5:54 p.m. and the 1940 Imperial Valley event was at 9:36 p.m. More recently, the 1989 Loma Prieta event was at 5:02 p.m.
Fiction: It's hot and dry—earthquake weather!
Facts: Many people believe that earthquakes are more common in certain kinds of weather. In fact, no correlation with weather has been found. Earthquakes begin many kilometers below the region affected by surface weather. People tend to notice earthquakes that fit the pattern and forget the ones that do not. In all regions of the world, “earthquake weather” is whatever type of weather prevailed at the time of the region’s most memorable earthquake.
Fiction: Someday there will be beach front property in Arizona.
Facts: The ocean is not a great hole into which California can fall, but is itself land at a somewhat lower elevation with water above it. The motion of plates will not make California sink—California is moving horizontally along the San Andreas Fault and up around the Transverse Ranges (coastal California mountains).
Fiction: We have good building codes so we must have good buildings.
Facts: The tragedy in Kobe, Japan, one year after the Northridge earthquake, painfully reminds us that the best building codes in the world do nothing for buildings built before that code was enacted. In many earthquake-prone areas of the United States, the building codes are out of date and therefore even new buildings are very vulnerable to severe earthquake damage. Fixing problems in older buildings—retrofitting—is the responsibility of the building's owner.
Fiction: Scientists can now predict earthquakes.
Facts: Scientists do not know how to predict earthquakes, and they do not expect to know how any time in the foreseeable future. However, based on scientific data, probabilities can be calculated for potential future earthquakes. For example, scientists estimate that during the next 30 years the probability of a major earthquake occurring is 67 percent in the San Francisco Bay area and 60 percent in southern California.
