Science 7 Quiz #2 4th Quarter

This wave creates a rolling motion, making the ground move up and down and side to side in the same direction

• Rayleigh wave

• P-wave

• S-wave

• Love wave

This is the point where the earthquake originates

• Epicenter

• Focus

• Seismic Center

• Tremor Point

These are smaller seismic events that may be recorded following the main earthquake

• Tremors

• Aftershocks

• Foreshocks

• Seismic Waves

These are two types of seismic waves released during an earthquake

• Body Waves

• Surface Waves

• Tsunami Waves

• P-Waves

This is used to assess the intensity of an earthquake in the Philippines

• PEIS or PHIVOLCS Earthquake Intensity Scale

• Richter Scale

• Moment Magnitude Scale

• Modified Mercalli Intensity Scale

This is the measure of an earthquake's effect on a specific location on the earth's surface

• Magnitude

• Intensity

• Seismicity

• Tremor

It is the measure of earthquake size, which reflects the amount of energy released from the source

• Magnitude

• Intensity

• Seismicity

• Tremor

It is an instrument that measures seismic vibrations detected during an earthquake

• Seismometer

• Barometer

• Thermometer

• Altimeter

These are the earth's vibrations caused by the sudden release of energy held in rocks that have been deformed by forces coming from moving tectonic plates

• Seismic Waves

• Tsunami Waves

• Sound Waves

• Ocean Waves

This is the point on the earth's surface directly above the focus

• Epicenter

• Hypocenter

• Seismic Center

• Tectonic Point
