Seismographs & Accelerographs

 

Seismologists from the SRC have been heavily involved in the development of the latest generation of seismographs and accelerographs that are manufactured in Melbourne, Australia by ESS Earth Sciences. Performance and reliability are a fundamental priority for a professional grade seismograph, but real world usability was also high on the list for the Gecko. Who better than a team of experienced field seismologists and data analysts to contribute to this aspect of instrument design?

The latest Gecko firmware can be found here.


The Gecko is supremely simple to use in the field. With its in-built display and keypad it can be completely configured without the need to connect a laptop or use a mobile device via Bluetooth or WiFi – your user interface is always there, ready to go. Within seconds of applying power, the Gecko is recording data continuously to the removable SD card, and it will continue to do so, trimming away the oldest data as the 32GB storage approaches capacity. It stores data in the most common earthquake data format, MiniSEED, and adds companion files so that our Waves viewing software displays corrected ground motion values, not just raw recorder counts. With just four buttons you can fully configure the Gecko: change station codes, set up triggering, configure telemetry, and much more. This is by far the easiest to use professional seismograph available today.


The budget conscious Compact is the affordable, fully featured entry into the Gecko range. The fully waterproof Gecko Rugged is the next step up for outdoor installation applications.

The Gecko is Australian designed and built, and competitively priced relative to other professional seismographs. Download the Gecko data sheet, view the seismic product range at ESS Earth Sciences, or contact us for more information.

 


We also have versions of the Gecko with built-in sensors. The Gecko Blast is our most affordable all-in-one digital velocity sensor, designed for continuous vibration and peak particle velocity (PPV) monitoring from nearby sources such as construction/demolition equipment or blasting activity. The Gecko SMA has a similar form factor but uses internal acceleration sensors for recording strong ground motion from high shock, high amplitude sources, for example when your monitoring point is near a blast source.

 


Our professional range of digital sensors uses high sensitivity velocity and acceleration sensors, all requiring a slightly larger, but still compact, waterproof chassis. The Gecko Tremor uses a velocity sensor that can be tuned for general vibration monitoring or optimised for detecting local earthquakes (within a few hundred kilometres). The Gecko SMA-HR and Gecko Prism 2g use very low noise acceleration sensors that allow you to detect low amplitude, low frequency signals, which are important for structural monitoring to clearly see the natural frequency and modal response of a building, dam, bridge, or other large structure.  Finally, for regional and global earthquake monitoring research applications we have the Gecko Prism 40s and 120s, able to detect long period signals and high frequency signals, which is the very definition of a “broadband seismograph”.
