75,000
230,000
152,000

Explanation:

• For the first question: Seawalls are physical structures built to protect coastal areas from tsunamis. In the 2011 Tohuko earthquake, the seawalls in Miyako were breached. Evacuation maps help people know where to go during a tsunami, warning sirens alert people, and the DART (Deep - ocean Assessment and Reporting of Tsunamis) system detects tsunamis in the ocean. But the question asks for the method that was a physical barrier (seawalls) which was breached.
• For the second question: The 2004 Boxing Day Tsunami had a death toll of approximately 230,000.

Answer:

• First question: Seawalls
• Second question: 230,000
