DistSummary: Arrival Summary

In TauP.R: Earthquake Traveltime Calculations for 1-D Earth Models

Description

Determine arrival times and information for all major phases arriving at a certain epicentral distance, and plot ray trajectories.

Usage

DistSummary(delta, h, model, phaselist = 'default', prop = "vp",
image.col = heat.colors(500), n = 200, ...)

Arguments

delta	Epicentral distance (degrees)
h	Focal depth (km)
model	Planet model
phaselist	Either 'default' for all available phases, or a character vector including desired phases
prop	Property by which to scale planet image: one of 'vp', 'vs', 'rho'.
image.col	Vector of colors for image
n	Resolution of image (pixels per side)
...	Other parameters for Rayfan

Details

This function is really just a wrapper for Rayfan to calculate arrivals for many phases at just one epicentral distance. Since each phase must be calculated separately, the use of the default phaselist will result in a long calculation time (minutes), and the plot will probably be crowded. It is generally better to define phaselist as a smaller vector or use Rayfan instead.

Value

Returns a list with the following elements:

p	Ray parameter for each arrival
t	Travel time for each arrival
dist	Epicentral distance (should be approximately the input dist)
phase	Phase of each arrival

# for an event occurring 100 degrees away at a depth of 40 km:

DistSummary(delta = 100, h = 40, model = model, phaselist = c('SKS', 'SKKS'))
