TauP Arrival Times Interface

Home View Menu Web Menus Data Menu Tools Menu Data Centre Services Alerts Tool

While the USGS ponders whether to create a new version of the arrival times calculator I have created an interface that links to the suggested alternative TauP. TauP is a Java command line program and probably beyond the bother of most Windows users, even if they know how to get at the command line in Windows.

With this interface I hope to ease the pain a little. There are two versions – one is built into the QVS Data program and can access events from the database, and the other is a standalone version for any Windows user.

IMPORTANT: I did not write TauP, and I am not responsible for the output or behaviour of TauP. You must install TauP on your system in order for this interface to work, and you MUST place the Taup-2.1.1 folder immediately below the root of a drive, for example C:\Taup-2.1.1

TauP may not work if there are any spaces in the working path.

QVSData program version

The interface program is found on the Tools menu but there is also a launcher on the right click context menu of a display listing.

If you are using the display form context menu you don’t have to do anything as the data for the earthquake you selected will be loaded into the boxes. (Jump to this part)

The initial screen looks like this

Please note that for the time being it is NOT possible to select phases. I need to resolve an issue with the batch file before I can make this work. Currently you get all phases.

You MUST now select the TauP folder before doing anything else. Click on ‘Select Folder’ at the bottom of the form.


Find the TauP folder and then click on OK. The folder will be inserted. You only have to do this once.

The easiest way of selecting an event in the QVSData program version is to click ‘Select Data’. You will then get another screen:


The selector will provide all events at or above the selected magnitude using the selected provider. The provider code is the same as the service job code so US07M1 is the USGS 7 day data job.

When you have selected the Date, the Provider and the Magnitude you click on ‘Search’ to get the list of events.


Click on an event and then click ‘Accept’


The event data is loaded into the front form.


If you have not already done so you must select the station that you wish to use for the calculation. You selection will be remembered and the next time you use the program it should already be selected in the list for you.

Click on ‘Get The Arrival Times’ and a black command screen should appear:


Do not do anything! You will have to wait about 10 seconds, or at most 20 seconds, before the screen vanishes and your arrival times are displayed.

The arrival times at the station, the second block of data, are to the nearest second and are based on the event time. The first block is the original output from the TauP program.
