Application to Wells Nevada Earthquake

Slip distribution from the inversion of 7 three-component, broadband displacement records. The hypocenter at 7 km depth is shown as the black square. The rupture is down dip and bilateral. The slip outside the main two asperity patch is not considered to be well resolved. Nearby seismometers
