1. The 2004 Indian Ocean earthquake and tsunami was caused by the rupture of the boundary between the India and Burma tectonic plates, which had built up seismic pressure over time. 2. When the plates ruptured, it released massive seismic energy that displaced water and caused towering tsunami waves that spread across the Indian Ocean. 3. The tsunami waves grew much larger as they reached shallow coastal waters, devastating many countries along the coasts of the Indian Ocean and killing over 250,000 people across 14 countries, making it one of the deadliest tsunamis in history.

5. 2. Accumulating seismic energy 1. Two overlapping tectonic plates become “stuck” 3. Stuck area ruptures releasing seismic energy 4. Tsunami waves spread
