In a case study, Hsin-Yi discusses the Indian Ocean Tsunami of 2004. Brought on by a 9.1 magnitude earthquake, the disaster resulted in 228,000 fatalities and $4.5 billion in damages. The most affected groups among those impacted by tsunami were vulnerable populations such as young children and the elderly.
Although the disaster caused severe damages to the local medical facilities and healthcare system, Hsin-Yi presents how local doctors, mobile medical projects, and field hospitals were able to respond to the disaster and help the impacted locations in recovering. Hsin-Yi also explores how the impacted regions have since improved their emergency communication systems. For example, following an earthquake off the coast of Sumatra in 2012, eight nations warned inhabitants of concerns regarding a tsunami through the use of text messages.
