Earthquake Hazards - SHORT GAME

The following choices are earthquake hazards EXCEPT:

• tsunami

• hurricane

• soil liquefaction

• surface rupture

Answer explanation

Warm ocean waters and thunderstorms fuel power-hungry hurricanes.

Hurricanes form over the ocean, often beginning as a tropical wave—a low pressure area that moves through the moisture-rich tropics, possibly enhancing shower and thunderstorm activity.

Therefore, hurricanes are atmospheric hazards.

Enumerate one natural sign of an impending tsunami

In this frequency map of expected number of earthquake occurrences, which state in the given choices is expected to have the most number of damaging earthquake shaking occurrences in a decamillenium?

(Note: the cut lines are state borderlines)

• California (Sacramento)

• Minnesota (Minneapolis)

• Washington State (Seattle)

• Massachusetts (Boston)

Answer explanation

Considering that the state of California is mostly colored red than the other states in the choices, we can identify that the state experiences more occurrences than Minneapolis, Washington State, and Massachusetts

Buildings and other structures can sink down into the ground or tilt over, whilst underground pipes and tanks may rise up to the surface.

These are effects of?

• earthquake induced landslides

• liquefaction

• earthquake induced subsidence

• surface rupture

Answer explanation

Liquefaction occurs when waterlogged sediments are agitated by seismic shaking. This separates the grains from each other, reducing their load-bearing capacity.

When the vibrations stop the sediments settle down again, groundwater is squeezed out of cracks and holes in the ground cause flooding. The aftermath of liquefaction can leave large areas covered in a deep layer of mud.

Disruptive up, down, and sideways vibration of the ground.

This is an effect of?

• tsunami

• surface rupture

• earthquake induced landslides

• ground shaking

Answer explanation

If an earthquake generates a large enough shaking intensity, built infrastructure, like buildings and dams, and lifelines, such as power and water networks, can be severely damaged. In large earthquakes, whole districts can be devastated by the multiple consequences of ground shaking.

In this hazard map, the darker the color, the ___ the ___ to ___.

• loving him was red

• lower, risk, tsunamis

• higher, intensity, earthquakes

• higher, risk, earthquakes

Answer explanation

The legend provides that the darker the color, the higher the risks to earthquakes.

Which of the given choice (s) is a/are signs (s) of an impending tsunami?

• a loud roar from the ocean

• a sudden rise or fall in sea level

• water near the shore recedes or pulls back significantly

• surroundings smell unusual

• get to higher ground immediately

• grab someone's foot so she does not have to run

• she should stay because she is in the open

• accept her own fate

The strongest shaking of the ground is felt at the epicenter.

• True

• False
