When Nature Strikes - Tsunamis

The video discusses the devastating impact of tsunamis, using the 2011 Japan tsunami as a case study. It explains how tsunamis are primarily caused by underwater earthquakes, particularly in subduction zones. Researchers like Anne Trehu and Dan Cox are working to understand and predict tsunamis by studying seismic data and testing tsunami impacts on structures. Their work aims to improve community preparedness and resilience against future tsunamis.

What was the magnitude of the earthquake that struck Japan in 2011?

• 8.5

• 7.5

• 9.0

• 8.0

What is the primary cause of most tsunamis?

• Volcanic eruptions

• Hurricanes

• Earthquakes

• Tidal waves

What is a subduction zone?

• A region where one tectonic plate goes beneath another

• A region where one tectonic plate slides past another

• A region where tectonic plates are stationary

• A region where two tectonic plates move apart

Why is the size of an earthquake not a reliable predictor of tsunami size?

• Mid-magnitude earthquakes can cause large tsunamis

• Tsunamis depend on the depth of the ocean

• Tsunamis are not related to earthquakes

• Tsunamis are only caused by large earthquakes

What is the focus of research at the OH Hinsdale Wave Research Laboratory?

• Analyzing tsunami impacts on structures

• Studying the origin of tsunamis

• Measuring ocean currents

• Predicting earthquake magnitudes

How do researchers at the laboratory simulate tsunamis?

• Using computer models

• Using virtual reality simulations

• Generating scaled-down waves in large pools

• Observing real tsunamis

What is the ultimate goal of becoming 'tsunami literate'?

• To predict the exact timing of tsunamis

• To improve coastal city planning and preparedness

• To increase public awareness of ocean life

• To eliminate the occurrence of tsunamis
