Twitter is a great resource in a crisis. Up-to-the-second reporting from citizens adds rich information.
In the last Santa Barbara fire, the Tea Fire, Twitter was being used primarily by early adopters with an interest in reporting the news.
In the recent Jesusita fire, a lot more people have adopted Twitter. While some of this is great: @SBRedCross has a lot of great information, for example. But a lot of the #jesusita posts and many more that result from a search of "santa barbara" are tweets offering prayers or stating how hot it is.
