摘要

Arriving at the Seismo Lab in 1981,I first worked with Hiroo Kanamori on the seismotectonics of the New Hebrides(Vidale and Kanamori,1983)(I don't remember why).Then with Rob Clayton I worked on finite-difference methods of modeling seismic waves,specifi-cally how to bump second-order methods to fourth-order and encode the inner loop in assembly language to make it run twice as fast(Vidale,1990).
