A tsunami is a series of large ocean waves typically caused by underwater earthquakes, volcanic eruptions, or landslides. These waves can travel across entire ocean basins at high speeds, often unnoticed until they reach shallow coastal waters, where they can grow to enormous heights and cause devastating impacts on coastal communities. When a tsunami strikes, it can lead to catastrophic flooding, destruction of infrastructure, and loss of life. Early warning systems and evacuation plans are crucial for minimizing the risks associated with tsunamis. Understanding the science behind tsunamis helps communities prepare for and respond to these powerful natural events.
