esl Pathways Bridges, Lesson 13 Earthquakes

The major cause of earthquakes is shifting tectonic plates.

When they happen at sea, earthquakes can generate seismic waves called tsunamis.

When loose soil, such as landfill, loses its ability to bear loads, the ground behaves like quicksand.

When they happen at sea, earthquakes can generate seismic waves called tsunamis.

They can trigger fires and landslides.

Earthquakes occur when shifting pieces of the Earth’s surface cause the ground to shudder.

Because the American Midwest was so sparsely populated, the death toll was light.

Subterranean forces cause gigantic plates of rock to shudder as they slip past each other.

Most earthquakes occur at the boundaries of these plates.

They rely on people to donate things that they need.

Subterranean forces cause gigantic plates of rock to shudder as they slip past each other.

They are barely noticeable and often appear as ripples on the surface of the water.

Tectonic plates are the fragments of crust that float on the Earth’s thick mantle.

About 35 earthquakes are observed around the globe every day, and about 18 major ones happen every year.

You have to evacuate your city and move to a safe place in the countryside for a while.

Since earthquakes will happen whether they are predicted or not, communities in many earthquake-prone areas such as southern California have upgraded building codes to make their structures less susceptible to damage.

• What kind of damage can earthquakes cause?

Mid-plate earthquakes, like the one at New Madrid, are usually large and destructive.

They can trigger fires and landslides.

Lesson 13 Earthquakes • Which areas of the world often have earthquakes?

Earthquakes have killed countless numbers of people and tossed their buildings around like toys.

Sometimes there are disastrous results.

Tectonic plates are the fragments of crust that float on the Earth’s thick mantle.

They are barely noticeable and often appear as ripples on the surface of the water.

Damage from earthquakes is not limited to buildings, bridges, and dams.

Subterranean forces cause gigantic plates of rock to shudder as they slip past each other.

Disaster victims often need a lot of help.

They are barely noticeable and often appear as ripples on the surface of the water.

When a Midwestern earthquake happens again, as experts say it surely will, the toll in human life and property destruction is expected to be high.

Japan has invested heavily in earthquake-proofing buildings in such areas as downtown Tokyo.

When they approach shores, they become monsters.

Tsunamis travel great distances at speeds equaling those of commercial jetliners.

Which is more valuable: human life or property?

Buildings can sink and even disappear.

A series of quakes near the town of New Madrid, Missouri, during the winter of 1811-1812 was felt as far north as Canada, as far south as the Gulf of Mexico, and rattled chinaware in Washington, D.C.
