Earthquakes and Tsunamis

Earthquakes are not very frequent natural disasters.

Tsunamis can only be caused by hurricanes in the ocean.

The outermost layer of the earth is not in one piece and is divided into fragments called plates.

The true cause of earthquakes was well understood by people in ancient times.

Landslides can be caused by earthquakes.

The earth is believed to be balanced on the horn of a bull according to scientific studies.

An earthquake of magnitude 6 has one and a half times the destructive energy of an earthquake of magnitude 4.

Tremors on the earth can only be caused by underground nuclear explosions.

The power of an earthquake is expressed in terms of magnitude on the Fujita scale.

Both Bhuj and Kashmir earthquakes had magnitudes lower than 7.5.

Seismic waves are recorded by an instrument called a seismograph.

Scientists can construct a complete map of the earthquake by studying seismic waves.

Underground explosions are a common cause of earthquakes.

Landslides are directly related to the movement of Earth's plates.

Scientists can accurately predict when and where the next earthquake will strike.

Tsunamis can only be caused by underwater landslides, not by earthquakes.

The movement of Earth's plates can lead to the formation of fault zones.

The Indo-Gangetic Plain is considered a high-risk area for earthquakes in India.
