Tsunami warnings were issued over the weekend following an earthquake on the Solomon Islands, leading to over 15,000 tweets mentioning the warnings. So, how does social media impact weather warnings?

Since then, we've seen social media serve as a hub of activity in the days leading up to, during, and following natural disasters around the world. "
