FAQs on Tsunami Video Lecture - Class 7

1. What is a tsunami?
Ans. A tsunami is a series of ocean waves caused by a large disturbance, such as an earthquake, volcanic eruption, or underwater landslide. These waves can travel across the ocean at high speeds and can cause significant damage when they reach coastal areas.
2. How do earthquakes trigger tsunamis?
Ans. When an earthquake occurs beneath the ocean floor, it can cause the seafloor to uplift or subside, creating a disturbance in the water above. This disturbance then propagates as a series of tsunami waves that can travel across the ocean and eventually reach distant coastlines.
3. Can tsunamis be predicted in advance?
Ans. While it is not currently possible to predict tsunamis with a high degree of accuracy in terms of timing and exact location, scientists can monitor and detect potential tsunami sources, such as earthquakes and underwater landslides, through advanced seismological and oceanographic technologies. This information can help in issuing timely warnings and evacuation orders.
4. What are the potential impacts of a tsunami?
Ans. Tsunamis can have devastating impacts on coastal communities. The powerful waves can inundate low-lying areas, destroy infrastructure, and cause loss of life. Additionally, tsunamis can lead to long-term economic and environmental consequences, including damage to coastal ecosystems and disruption of local economies.
5. How can individuals and communities prepare for a tsunami?
Ans. It is crucial for individuals and communities living in coastal areas to have a comprehensive tsunami preparedness plan in place. This includes staying informed about tsunami risks and evacuation routes, practicing tsunami drills, and having emergency supplies and evacuation kits readily available. Additionally, coastal infrastructure should be designed and built to withstand tsunami forces to minimize damage and protect lives.
