Waves – Free Download

The world’s best earthquake waveform viewer. Waves is able to read MiniSEED, PC-SUDS, and many other data formats. Download free for Windows, Mac and Linux

The frequency domain plot in Waves has had a major overhaul in version 3.2. The linear scale FFT relative power plot remains, but the log-scale plot has been replaced by a Power Spectral Density (PSD) plot. This can be viewed scaled to the data’s power range, or plotted relative to the Peterson NLNM and NHNM curves.
New buttons in the frequency window allow you to reset the zoom (if you’ve zoomed in to a selection), filter to the selection (tick), filter out the selection (cross), and swap between linear, log and NxNM views.
We’ve also added poles, zeroes and normalising factor fields to more accurately scale the PSD plot, and these factors are saved to SUDS format files.

Version 3.0 of Waves introduced the ability to rotate your waveforms, both horizontally and in elevation. It also allows the customisation of the magnitude estimation formula. Other features include the ability to select and zoom in the FFT window to filter your data, either through selection or exclusion by notching out frequency bands. See the Waves user manual for all the details.

Want to try out some sample data? Check out this magnitude 6.3 earthquake recorded on six Gecko accelerographs ranging from 40km to 110km from the hypocentre. You can even save it as a KML file and see a rough earthquake location using Google Earth.

Simply click on the links below to download the version for your operating system. Waves is a Java application and requires that the Java Runtime Environment (JRE) is installed on your computer, which is available as a free download.

The free version of Waves is supported by a 10-second advertisement which can be removed by purchasing a product key for A$110 per computer. Contact us if you would like to purchase product keys. A product key is available at no cost if you have purchased a Gecko seismograph or accelerograph. Limited to one single-use code per Gecko.
