In 2004, an earthquake struck Sumatra in Indonesia along a tectonic plate boundary under the ocean. When the plates shifted, it caused a tsunami wave to spread outwards and hit different coastlines anywhere from 2 to 8 hours after the quake. Unfortunately, the tsunami waves were so powerful that it became known as one of the deadliest natural disasters in history with over 220,000 deaths and $14 Billion in damages. Which of the following is the NOT a likely reason why the 2004 Sumatra earthquake caused so much damage?

A. Tsunamis occur instantly and are not preceded by any warning signs.

B. Poor earthquake detection systems did not give people warnings to move farther inland.

C. Most of the countries affected by the tsunami were poor and did not have well-established building codes.

D. The earthquake that caused the tsunami was a magnitude 9.2.
