## The Joyner-Boore Attenuation Data

## Usage

    data(attenu)

## Format

A dataframe with 182 observations on 5 variables.

[,1] | event | numeric | Event Number
[,2] | mag | numeric | Moment Magnitude
[,3] | station | factor | Station Number
[,4] | dist | numeric | Station-hypocenter distance (km)
[,5] | accel | numeric | Peak acceleration (g)

## Description

This data gives peak accelerations measured at various observation stations for 23 earthquakes in California. The data have been used by various workers to estimate the attenuating affect of distance on ground acceleration.
