Question

According to the notes, which of these is NOT a common trigger for tsunamis?

• A. Underwater landslides
• B. Large underwater volcanic activity
• C. Meteorite impacts in the ocean
• D. Gradual sea level rise

Answer 1

Answer:

D. Gradual sea level rise

According to general scientific understanding (as the previous "notes" were from our conversation about the meaning of the word 'tsunami', not a document about tsunami triggers), gradual sea level rise is NOT a common trigger for tsunamis.

Common triggers include:

• Earthquakes: Especially large underwater earthquakes that cause significant vertical displacement of the seafloor.

• Underwater Landslides: Large slides of material on the seafloor.

• Volcanic Eruptions: Particularly those that cause caldera collapse or displace large amounts of water.

• Meteorite Impacts: Though very rare, a large impact in the ocean could generate a tsunami.
