Social media has been used extensively in recent disasters by emergency managers particularly to warn people and help in the co-ordination of response and recovery. However, its use in disaster prevention and preparedness is less understood.

It concludes that it is generally underutilised in major DRR awareness strategies, although there are robust programs operating in some countries with high social media use.
