Current Seismic Activity in Tucson

The links below will take you to the past 24-hour feed of the Global Seismograph Network station TUC which is located in Tucson, AZ. These seismograms display the vertical component of the broadband channel of station TUC. The digitizer samples activity 20 times per second. There are three images available:


BHZ Non-filtered
This displays the recent raw broadband vertical data.

Vertical long period.
This displays the recent long-period data which will clearly display large (M>5.5) earthquakes. The raw data is filtered with a bandpass filter between 0.01 and 0.067 Hz.

Vertical short period.
This displays the recent high-frequency data. This record is a fantastic example of mining activity around Tucson. The high pass filter applied to the data has a cutoff frequency of 1.Hz



Data is retrieved from the station every 5 minutes on the minute in miniseed format. The raw and filted images are generated one minute later and the display is updated. Five minutes past the hour every hour the display is regenerated to display data from only 24 hours.

If there is no image, it may be that a new image is under construction. Try waiting a 15-30 seconds, and then reload this page.

The seismogram display software was developed by Kiriaki Xiluri using ObsPy.
