The news media this morning has been discussing earthquake warnings in the wake of the catastrophe in Haiti. Please allow me to clarify: Right now, there is no such thing as an earthquake warning. Unfortunately, the science does not exist to create them.
Some disagree that earthquake warnings should even be attempted. Here is that article from Disaster Recovery Journal. These objections were virtually the same as the arguments made against issuing tornado warnings 60+ years ago.
DRJ was kind enough to publish my rebuttal article where I make the case that, once the science is sufficiently advanced, we should begin a program of earthquake warnings.
I suggest you read both and make up your own mind. Comments are always welcome.
