\description{The data set give the locations of 1000 seismic events of MB > 4.0.
The events occurred in a cube near Fiji since 1964.

There are two clear planes of seismic activity. One is a major
plate junction; the other is a trench off New Zealand.  These data
constitute a subsample from a larger dataset of containing 5000
observations.
