I grew up in one of the most aseismic regions of the planet but decided as a child that I wanted to be a seismologist.Ignoring all the naysayers who claimed that no one really did that for a living and who told me I should choose something sensible like neurosurgery or enginee-ring,I showed up at the Caltech Seismo Lab in the summer of 1985.I arrived equipped with the right skills but,as I quickly learned,no real knowledge of the breadth of seis-mological research.On day one I made the usual rounds of the faculty and soon thereafter began working on a project relocating earthquakes of a swarm in the Coso region.
