Fires are started by molten lava that erupts from the subduction zone

Fire is brought along with the tsunami as it moves

Fires are started when people build fires after the tsunami for heat

Fires are not associated with tsunamis because it is too wet

The speed of the wave as it nears the shore

The speed of the wave when it is on land

The amount of damage done by the wave

The number of waves produced by the earthquake

The earthquake that produced it was very big.

The earthquake that produced it was associated with a Subduction Zone.

Buildings were not built to withstand a tsunami.

Tsunamis had never been recorded in that area.

A wave in the ocean usually caused by tides

A wave in the ocean usually caused by hurricanes

A wave in the ocean seen only in Japan

A wave in the ocean seen only in the summer months

The earthquakes aren't strong enough

The earthquakes aren't in the ocean

The earthquakes don't move fast enough

The earthquakes don't horizontally displace the water in the ocean

Boats will usually mistake the large waves for tidal waves and not recognize them as Tsunami.

Because Tsunamis are produced by earthquakes, the boats are probably still recovering from the initial tremors to notice a change in the waves.

Tsunami waves don't break and therefore won't be noticed by boats.

The statement isn't true. Tsunami waves are always noticed by boats in the open ocean.

The waves increase in amplitude, decrease in both speed and frequency.

The waves decrease in amplitude and frequency, increase in speed.

The waves decrease in amplitude, increase in both speed and frequency.

The waves amplitude, frequency, and speed all stay the same.

distant tsunamis aren't dangerous

distant tsunamis are larger than local tsunamis

distant tsunamis are triggered in remote parts of the ocean

distant tsunamis hit after the local tsunamis

Shorelines in the Indian Ocean

Shorelines near the Hawaiian volcanoes

Shorelines near the San Andreas Fault

All shorelines are at equal risk for tsunamis

Contaminated water supplies

Disease

Coastline erosion

Erosion

Asteroids

Yes. Human structures on the shoreline increase the wave amplitude.

Yes. Human use of the water increases the wave amplitude.

Yes. Human use of the water decreases the wave amplitude.

Yes. Global warming is causing an increase in frequency and magnitude of tsunamis.
