Shaanxi Earthquake of 1556, This was the deadliest quake ever recorded. It claimed the lives of about 830,000 people. At that time, most inhabitants in the affected areas were living in Yaodongs or artificial caves. They were buried alive when the huge tremors caused the cliffs in which these caves were located in, to collapse.

What is a movement of earths crust?

The earth has two types of crust; continental crust and the oceanic crust.

What is oceanic crust

lisette02197 — 2015-03-23 12:27:40 UTC

The thin part of earths crust that underlies the ocean basins.

Which continental crust is older?

lisette02197 — 2015-03-23 12:29:41 UTC

The oceanic crust is young compared to the continental crust and is consisted of basaltic rock.

What is the continental crust?

The thick part of earths crust that forms large land masses. It is more complex then the oceanic crust.

Why do Earthquakes Occur?

lisette02197 — 2015-03-31 12:04:29 UTC

Earthquakes occur because the sudden release of energy causes the seismic waves that make the ground shake.

How long can a Earthquake last?

lisette02197 — 2015-03-31 12:07:32 UTC

An earthquake can last 10 to 30

seconds.

Earthquakes that Occured

The 1906 Francisco earthquake killed 3,000 people.

Key Terms

Faults- a place where sections of the earth move close together.

Seismic Waves- One of the two main types of elastic body waves, it gives them there name because they move through the body of a wave, unlike a surface wave

Lithosphere- is the rigid outer layer of the earth, which is made up of the crust and upper mantle

Tectonic Plate- is the two sub layers of the earth's crust that will move, float, and occasionally fracture the infracture of the continental drift

Subduction zone- where to lithospheric plates come together, and one rides over the other

Effect of an Earthquake

lisette02197 — 2015-04-07 12:19:58 UTC

Most earthquake-related deaths are caused by the collapse of structures and the construction practices play a tremendous role in the death toll of an earthquake. In southern Italy in 1909 more than 100,000 people perished in an earthquake that struck the region.
