Tsunami

Tsunamis are powerful natural disasters caused by underwater disturbances like earthquakes, landslides, and volcanic eruptions. They form massive waves that can cause significant destruction when they reach shallow waters. The 2004 Indian Ocean tsunami was one of the deadliest, with waves reaching 30 meters high and claiming over 200,000 lives. While small tsunamis occur frequently, major ones are rare. Modern technology allows for tracking tsunamis, providing vital warnings to affected areas, with hopes of improving safety measures in the future.
