Tsunami Warning Systems and Sensors

The video tutorial covers day four of a plate motion engineering internship, focusing on tsunami warning systems. Students learn about different types of tsunami sensors, their functions, and how to analyze them. Activities include connecting to the Future workspace, reading about tsunami warning systems, and using the Tsunami Alert tool to test sensor placements. Group investigations explore sensor detections, breaks, and false alarms. The session concludes with after-hours work, including a project summary and home exploration of tsunamis.

What is the primary focus of the internship on day four?

• Studying tsunami warning systems

• Learning about earthquake-resistant buildings

• Understanding weather patterns

• Exploring marine biology

Which type of plate boundary is associated with ocean trenches?

• Convergent boundaries

• Passive boundaries

• Divergent boundaries

• Transform boundaries

What is a key criterion for designing tsunami warning systems?

• Reducing sensor sensitivity

• Maximizing sensor size

• Increasing sensor cost

• Minimizing average warning time

Which sensor type is known for being very reliable but expensive?

• Deep sensors

• Airborne sensors

• Shallow sensors

• Surface sensors

What is a common issue with deep sensors?

• They rarely break

• They are easy to install

• They often produce false alarms

• They are inexpensive

How can you improve the warning time for a tsunami?

• Move the earthquake sensor further away

• Place the shallow sensor closer to the earthquake

• Add more sensors in random locations

• Move the shallow sensor further away to prevent breaking

What should be done if a sensor is not detecting any earthquakes or tsunamis?

• Leave it as it is

• Remove or relocate the sensor

• Add more sensors nearby

• Ignore the issue

What is a potential cause of false alarms in tsunami warning systems?

• Sensors placed in deep water

• Sensors placed too far from the coast

• Sensors detecting only small earthquakes

• Big earthquakes that do not generate tsunamis

What is the purpose of the project summary form?

• To record early ideas about warning system designs

• To evaluate sensor costs

• To analyze ocean currents

• To study weather patterns

Why is Sri Lanka at risk for tsunamis?

• It is located near a divergent boundary

• It is far from any plate boundaries

• It has a high elevation

• It is near convergent plate boundaries
