Study Notes
Tsunami Causes and Characteristics
- Most tsunamis are primarily caused by underwater earthquakes, particularly those occurring along tectonic plate boundaries.
- Tsunami waves are described as long-wavelength waves that can travel across entire ocean basins with great speed.
Tectonic Plate Dynamics
- When tectonic plates get stuck, stress accumulates over time until it is released suddenly as an earthquake, potentially triggering a tsunami.
Wave Speed and Behavior
- Tsunami waves can travel at speeds up to 500-600 miles per hour (about 800-965 kilometers per hour) in deep water.
- As tsunami waves approach shallower water, their height increases dramatically due to the conservation of energy, leading to potentially devastating coastal impacts.
Other Tsunami Triggers
- Besides earthquakes, volcanic eruptions and underwater landslides can also generate tsunamis.
Tsunami Characteristics
- A key characteristic of tsunamis is their ability to generate a series of waves, often leading to multiple surges that can impact coastlines in quick succession.
Pacific Tsunami Warning System
- The Pacific Tsunami Warning System is based in Hawaii and is responsible for monitoring seismic activity and issuing warnings for potential tsunami threats.
- Its primary purpose is to alert regions at risk of tsunamis, helping to ensure public safety.
Historic Tsunami Events
- The country that experienced the largest tsunami ever recorded is Japan, particularly noted for the 2011 Tōhoku earthquake and tsunami.
Occurrence Frequency
- Tsunamis typically occur multiple times a year around the world, but most are small and go unnoticed.
Key Statement Validation
- Understanding specific statements regarding tsunamis and their characteristics is crucial for comprehensive knowledge of this natural phenomenon.
