FAQs on Tsunami Video Lecture - Geography for UPSC CSE

1. What causes a tsunami?
Ans. A tsunami is usually caused by underwater earthquakes or volcanic eruptions. When these events occur, they can create a sudden displacement of water, resulting in powerful waves that radiate outward from the source.
2. How fast can a tsunami travel?
Ans. Tsunamis can travel at extremely high speeds, reaching up to 500 miles per hour (800 kilometers per hour) in the open ocean. However, as they approach shallow water near the coast, their speed decreases, and the wave height can increase dramatically.
3. Can a tsunami be predicted in advance?
Ans. While it is not currently possible to predict the exact occurrence of a tsunami, scientists can monitor seismic activity and oceanic conditions to provide early warnings. Tsunami warning systems can help alert coastal communities and give them time to evacuate if necessary.
4. How far can a tsunami reach inland?
Ans. The distance a tsunami can reach inland depends on various factors such as the size of the wave, the coastal topography, and the angle of the shoreline. In some cases, tsunamis have traveled several miles inland, causing significant devastation.
5. What precautions should be taken during a tsunami warning?
Ans. During a tsunami warning, it is crucial to follow evacuation orders issued by local authorities. Move to higher ground or an elevated area away from the coast. Stay tuned to emergency alerts, listen to instructions, and avoid going near the beach or low-lying areas until the warning is officially lifted.
