The following books are very useful to understand disasters.
1. At Risk: Natural Hazards, People’s Vulnerability, and Disasters
2. Measuring Vulnerability to Natural Hazards: Towards Disaster Resilient Societies
3. Disaster Theory

1. “At risk” was already mentioned.

At Risk: Natural Hazards, People’s Vulnerability and Disasters

2. Birkman’s Measuring Vulnerability to Natural Hazards. This book is really really useful to understand the vulnerability of disaster research perspectives. The first, we can recognize what the vulnerability is. The second, this clarifies the vulnerability based on the people living in the areas. So the book divided the chapters or sections by the national, local, and community level. A brief explanation is found in the UN websites. An attached url also can be referred. This helps us to understand the Index, indices, and Indicators related work, which is internationally renown.

Measuring Vulnerability to Natural Hazards: Towards Disaster Resilient Societies

However, I also notice the vulnerability is one of the western thinking words facilitated by UN or developed countries. These kinds of “popular words” sometimes stop us to think the true meanings and the question of why this becomes popular. To avoid this, we can read these kinds of books from various perspectives.

3.Disaster Theory is very important to grasp the whole picture of what is the disasters and related terminologies. This book taught me a lot.
