Do we really have a good grip on the true scale of disaster threats? A year ago today, Typhoon Haiyan began its course to devastate the central Philippines. Since then, there has been a seemingly never-ending flow of stories about disasters from around the world and weird weather on our doorsteps.
In a bygone era, some folks may have believed that theory, but even today there are earthquake anecdotes that aren't exactly the stuff of modern science. Let's take a look at them: It's impossible to determine whether a dog is behaving in an unusual manner because it smells an earthquake coming or a cat across the street.
Changes in animal behavior sometimes have been observed prior to earthquakes, but that behavior is not consistent, and sometimes there's no perceptible behavior change prior to an earthquake. Earthquakes occur during "earthquake weather.
Earthquakes take place miles underground, and can happen at any time in any weather. Big earthquakes always occur early in the morning. Just as earthquakes don't care about the weather, they can't tell time.
The Imperial Valley quake was at 9: People who perpetuate the time and weather myths tend to remember the earthquakes that fit the pattern and forget about the ones that don't. California could fall into the sea because of an earthquake. The San Andreas Fault System is the dividing line between two tectonic plates.
The Pacific Plate is moving in a northwesterly direction relative to the North American plate. The movement is horizontal, so while Los Angeles is moving toward San Francisco, California won't sink. However, earthquakes can cause landslides, slightly changing the shape of the coastline. The ground can open up and swallow people.
You've seen the image in books, movies and TV shows. That's not how it works. If a fault could open up, there wouldn't be any friction. Without friction, there's no earthquake.
But earthquakes cause settling and other ground deformation that can include open fissures into which people, cars, etc. The safest place to be in an earthquake is under a doorway. That's true only if you live in an unreinforced adobe home. In a modern structure the doorway is no stronger than the rest of the building.
Actually, you're more likely to be hurt by the door swinging wildly in a doorway. And in a public building, you could be in danger from people trying to hurry outside.
If you're inside, get under a table or desk and hang on to it. Small earthquakes keep big ones from happening. Each magnitude level represents about So while a small quake may temporarily ease stress on a fault line, it does not prevent a large temblor. The magnitude of an earthquake determines whether disaster assistance is forthcoming.
A magnitude 7 quake in the middle of the desert is likely to do less damage than a magnitude 6 in downtown Los Angeles or San Francisco. It is the magnitude of the damage, not the earthquake, which determines the level of response.
We have good building codes, so we must have good buildings.
That's true -- provided you're talking about buildings constructed under current building codes.Jan 18, · Debunking the Myth That Earthquakes and Full Moons Are Linked Image Devastation in Valparaiso, Chile, from the earthquake that killed more than people.

Chapter 2 - Earthquake Myths Qāf volcano, Caucasus; (vi) earthquakes as fundamental cause of mountain building in the Zoroastrian Iranian creation myth (ca. BCE); (vii) shaking of the solid sky made of stone (ca. I review and examine the multifaceted metaphors in the myths and oral traditions that still exist on the Iranian. Jamie and Adam look into the myth that Nikola Tesla invented an earthquake machine that almost destroyed his research building. Tory, Grant, and Kari look into the myth of the exploding lava lamp and if other containers can explode with deadly consequences. However, an earthquake of far greater proportions, with far greater consequences, has hit the nations of the world — The Darwinian Earthquake. This earthquake has shaken the foundations of Christianity — in our western nations, we see the Christian fabric that once existed in tatters.
And in the San Francisco Bay Area where multiple geological faults crisscross the region we face a seismic vulnerability that's especially unnerving.
