Documentation

On this Picostat.com statistics page, you will find information about the quakes data set which pertains to Locations of Earthquakes off Fiji. The quakes data set is found in the datasets R package. You can load the quakes data set in R by issuing the following command at the console data("quakes"). This will load the data into a variable called quakes. If R says the quakes data set is not found, you can try installing the package by issuing this command install.packages("datasets") and then attempt to reload the data. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the quakes R data set. The size of this file is about 24,064 bytes.


Locations of Earthquakes off Fiji

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.

Usage

quakes

Format

A data frame with 1000 observations on 5 variables.

[,1] lat numeric Latitude of event
[,2] long numeric Longitude
[,3] depth numeric Depth (km)
[,4] mag numeric Richter Magnitude
[,5] stations numeric Number of stations reporting

Details

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

Source

This is one of the Harvard PRIM-H project data sets. They in turn obtained it from Dr. John Woodhouse, Dept. of Geophysics, Harvard University.
