L5-7 Geology

Topography

The physical shape and elevation features of the land surface (hills, cliffs, valleys, river beds)

P-waves

Which travel faster? P-waves or S-waves?

Indonesia

Which country has the most earthquakes?

Magnitude

This is the size of the earthquake

Moment Magnitude (Mw)

• This is based on physical properties of the earthquake derived from an analysis of all the waveforms recorded from the shaking.

• First the seismic moment is computed, and then it is converted to a magnitude designed to be roughly equal to the Richter Scale in the magnitude range where they overlap.

Intensity

the measure of shaking at each location, and this varies from place to place, depending mostly on the distance from the fault rupture area.

Moment Magnitude

Based on physical properties of the earthquake derived from an analysis of all the waveforms recorded from the shaking.

Shindou Scale

What scale does Japan use to measure the shaking intensity?

Liquification

This is a a process by which water-saturated sediment temporarily loses strength and acts like a fluid

Chicxulub Impact

Possibly what killed the dinosaurs

7.5

What was the magnitude of the Noto Peninsula Earthquake?

Mt. Fuji

Tateyama

Hakusan

What are the 3 holy mountains of Japan?

Hawaii

Jeju - Hallasan

Changbaishan

Yellowstone

What are some intraplate volcanoes?

Volcanic Bombs

large chunks of molten or semi-molten rock that are violently ejected from a volcano during an explosive eruption.

Basalt

This is a dark, fine-grained volcanic rock that is low in silica but high in iron and magnesium.

Rhyolite

This is a light-colored (often pink, white, or light gray) volcanic rock. It is the exact opposite of _____: it is extremely high in silica but low in iron and magnesium.
