the discovery of earthquakes by Fatima Caballero

Earthquakes are the powerful movement of rocks in the Earth’s crust. The fast release of energy creates seismic waves that travel through the earth.

Scientists use the different speeds of seismic waves to locate the epicenter of earthquakes.

earthquakes destroy homes and kill people.

a Richter scale is used to find out how big is the earthquake and to find the magnitude to warn people and save lives.

earthquakes are formed by tectonics plates.

earthquakes shake the ground and sometimes cause the ground to crack.

some earthquakes occur under ground and cause damage on ground.

fatimarc0901 — 2015-03-23 15:21:55 UTC

some earthquakes happen on fault lines.

There are four kinds of faults, strike slip, normal and thrust, and reverse. each fault line have different forces that can push or pull on the crust that causes rocks to slide up, down or past each other.

earthquakes are classified by S waves and P waves.

earthquakes have different rates, and the bigger the rate, the larger the destruction.

an earthquake is a sudden release of energy in the earths crust that creates seismic waves.

fatimarc0901 — 2015-03-23 15:31:11 UTC

The damage caused by earthquakes also depends on their depth and fault type.

fault

fatimarc0901 — 2015-03-24 15:15:30 UTC

crushed rock separating blocks of the earths crust.

epicenter

fatimarc0901 — 2015-03-24 15:15:35 UTC

the point on the earth's surface vertically above the focus of an earthquake.

transform boundaries

fatimarc0901 — 2015-03-24 15:15:50 UTC

boundaries that slide by each other.

S wave

fatimarc0901 — 2015-03-24 15:15:59 UTC

a type of elastic wave

P wave

fatimarc0901 — 2015-03-24 15:16:18 UTC

a can be produced by earthquakes and recorded by seismographs.

fatimarc0901 — 2015-03-24 15:16:46 UTC

a smaller earthquake that occurs after a larger earthquake.

richter scale

fatimarc0901 — 2015-03-24 15:16:55 UTC

a scale used to record earthquakes.

earthquakes involve a powerful movement ofrocks.
