attenu: The Joyner--Boore Attenuation Data

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.

Usage

attenu

Format

A data frame 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)
