Values of the peak amplitudes at the ShakeMap map grid nodes. File is ASCII text in the following format:

First line is a header with:
<name/CUSPID of event> <mag> <epicentral lat> <epicentral lon> <MMM DD YYYY> <HH:MM:SS timezone> <W bound> <S bound> <E bound> <N bound> (Process time: <time>) <Location String>

The first 'time' field is the time of the event.
'Process time' is the time this file was last updated.

ex:
Northridge 6.7 34.213 -118.5357 JAN 17 1994 04:30:55 PST -119.1857 33.7775 -117.857 34.6485 (Process Time: Wed Nov 4 17:25:18 1998) Northridge Earthquake

For large or historic earthquakes the "Location String" will usually be the name of the earthquake, otherwise it will be something of the form "12.1 mi. SSW of Carpinteria, CA"

The remaining lines are of the form:
<lon> <lat> <pga> <pgv> <mmi> <psa03> <psa10> <psa30>

psa03 = spectral acceleration at 0.3 s period, 5% damping.
psa10 = spectral acceleration at 1.0 s period, 5% damping.
psa30 = spectral acceleration at 3.0 s period, 5% damping.

For pga value == (%g)
For pgv and psa?? value == (cm/s)
For mmi value == Intensity
For psa value == (%g)

Contour lines of the peak ground motion amplitudes in ASCII text.

The data of the file is in the form <lon> <lat> <contour_value>, with each contour delimited by a 1-line header starting with '>'.

For example:
> 20 contour
-118.525 34.134 20
-118.5 34.1477 20
-118.492 34.125 20
-118.5 34.1007 20
-118.525 34.1085 20
-118.538 34.125 20
-118.525 34.134 20
> 20 contour

Contour lines of the peak ground motion amplitudes. File is ASCII text in the ArcInfo export format. Can be imported into ArcInfo as a coverage.

Contour lines of the peak ground motion amplitudes in ArcView shape files. This is collection of three files compressed in zip format.

The three files are:
.dbf = A DBase file with layer attributes
.shp = The file with geographic coordinates
.shx = An index file

A table of earthquake and station parameters, formatted to be read easily by humans. An XML formatted file is also available, and is the best option for parsing the information by computer.

The earthquake information includes: CUSP ID, magnitude, date, time, epicenter coordinates and depth.

The station information includes name and/or code, location coordinates, and peak velocity and acceleration values.

Stations may be flagged to indicate they were not used in the ShakeMap processing. The types of flags are indicated at the bottom of the list.

A table of earthquake and station parameters, tagged in XML format for parsing by computer. The DTD defining the structure of the XML flags is incorporated in the file.

The earthquake information includes: CUSP ID, magnitude, date, time, epicenter coordinates and depth.

The station information includes name and/or code, location coordinates, and peak velocity and acceleration values.

Stations may be flagged to indicate they were not used in the ShakeMap processing. The types of flags are indicated at the bottom of the text version of the station list.
