Why are San Francisco and the Bay area at risk from a powerful earthquake?

∙ 12y ago
San Francisco has been built on a fault line called the San Andreas Fault. It is a fracture in the crust of the Earth. San Francisco sits on the edge of the pacific tectonic plate. The pacific tectonic plate collides with the North American tectonic plate, causing earthquakes. San Francisco also has soft soils so it's very easy for an earthquake to happen that causes bad damage.

How do the data from the movements of seismic waves help geologists determine the earthquake risk for an area?
If an area has a strong amount of seismic waves along, or around, you can predict if an area is active for earthquakes
Is Manitoba a high risk of a major earthquake?
no its the least most expected there to be an earthquake 'cause im from Manitoba :D
What is the earthquake risk for Mexico?
There is a small to moderate risk of a major earthquake in Mexico. Last earthquakes with major loss of live were recorded on 1957 and 1985 with magnitudes of 7.9 and 8.1 on the Richter scale.
The chance that an earthquake will occur in your town during the next year is an example of?
Risk
What is the main factor in determining the risk that location might have an earthquake?
Magnitude :D
Where are the high risk for earthquakes?
San Francisco is one area at high risk; the San Andreas fault is quite active. Any area near a fault line is at high risk of earthquake activity.
What natural processes make San Francisco and the bay area at risk from powerful earthquakes?
the San Andreas fault
What natural processes make San Francisco so at risk?
i have no clue! i need to find out an answer as I'm doing a geography piece of homework and the question is .... what natural processes make San Francisco and the bay area at risk from powerful earthquakes ?
What can help a geologist determine the earthquake risk for an area?
Geologists can determine the risk for an earthquake by measuring the seismic waves along faults as well as friction using a seismometer.
Why is San Francisco at risk from earthquakes and also can you explain the type of plate boundary and movement and include the basic theory of plate tectonics?
The reason why San Francisco and the Bay area are at risk from powerful earthquakes is because of the San Andreas Fault.also, the two tectonic plates, are the pacific plate and the American plate.
Which location would have the most short-term risk of an earthquake?
An Area along an active fault that has not had recent earthquake activity(:
How do the data from the movement of seismic waves help determine the earthquake risk for an area?
If an area has a strong amount of seismic waves along, or around, you can predict if an area is active for earthquakes
How is a fault line connected to the tsunami?
The fault line is the subduction zone. The earthquake cause there is a megathrust earthquake. Megathrust are one of the most powerful earthquake. In order for a tsunami to be created the earthquake must be at least 7.5 or higher. Every megathrust earthquake creates a tsunami. The 8.8 earthquake that struck off the coast of Chile is one of the fault lines that created a tsunami. But the tsunami wasn't not big when it hit Hawaii. But in 1960, a 9.5 earthquake that struck off the coast from the same area generate a powerful tsunami that hit Hawaii and Japan. The waves was 35 ft when it hit Hawaii. The 2004 Indian Ocean tsunami was cause by a fault line. There is a risk in the Pacific Northwest. Where are fault there capable of creating powerful earthquake and tsunami. It's now since 300 years since that last time it happened in 1700. Now the stress is building there and scientist said that it has a 1 in 50 chance that the area will rupture in the next 50 years.
How do the data from the movements of seismic waves help geologists determine the earthquake risk for an area?
If an area has a strong amount of seismic waves along, or around, you can predict if an area is active for earthquakes
What two factors do geologists consider when determining earthquake risk for a region?
By locating where faults are active and where past earthquake have occurred.
Where are the areas that are at greatest risk from earthquake?
Where plates meet
If the region in which you live has not experienced an earthquake in 200 years your earthquake hazard is low?
True, but be mindful of risk.
