We have also found out that little quakes do not necessarily release stress on fault lines, but sometimes actually builds stress on the faults next to them. Activity on one fault can also trigger another fault to pop (saw that one happen at Yucca Mountain a few years ago).

So you're saying I need Volcano insurance on my new house?
