1. Introduction

Natural disasters are associated to chaotic situations in which information is usually incomplete and imprecise, and this lack of information makes difficult the process of making decisions and managing effectively catastrophes.

• Public awareness is an essential element of preparedness for saving lives and livelihoods.•Individuals and communities play important roles in managing risks from natural hazards.

5. Conclusions

Conclusions

Disasters2.0 has been shown as a web2.0 based platform which enables sharing and managing disasters information generated by users.

The platform provides a REST API which enables any client to interact with it. As an example, a web client and a mobile client have been developed.

Intelligent techniques can also leverage the REST API to interact with the platform such as the Expert System or the Multiagent Platform developed.
