Explain the Geology of Earthquake Flashcards

The waves advance in a backward-rotating, elliptical motion.

The large left step in the San Andreas fault in the Los Angeles area causes compressive ruptures along east-west-oriented faults as in the 1971 San Fernando and 1994 Northridge events.

Constraining bends in large strike-slip faults commonly ‘lock up’; thus, movements there tend to be

Velocities for waves in granite are about 5.5 to 6 km/sec, but in water they slow to 1.5 km/sec.

Earth's crust is less dense then?

Which of the following states has the lowest earthquake risk

The heat that transformed the Earth early in its history came primarily from all but which of the following?

At present, after subtracting deaths from births, world population increases 1.2 percent per year for a doubling time of .

After lava cools below the point, about 550

The rigid outermost layer of the Earth is called:

The Great Basin region between the eastern Sierra Nevada in California and the Wasatch Mountains in Utah in response to plate tectonic forces

On 3 November 2002, a large earthquake occurred in . Because of its similarity to the 1857 Fort Tejon earthquake on the San Andreas fault, this event has been compared to the much-anticipated ‘Big One’ in Southern California.

The reflectivity of the Earth’s surface is also called its

The Dead Sea and the Sea of Galilee .

Before plate tectonics had taken off what were the primary bases of information supporting it
