The Gecko seismograph is, at its core, simply a data logger that records voltage. That voltage comes from seismic sensors – there are dozens and dozens of them on the market, and the Gecko supports them all.
The GeckoLink accessory enables direct-from-site SeedLink streaming using the power of a Raspberry Pi, and introduces a web interface for remote data visualisation, remote configuration, and data management.
Here’s an animation of the motion of a building, recorded on three floors during a magnitude 6.1 earthquake whose hypocentre was around 130km away.
The professional range of Gecko seismographs and accelerographs has been redesigned for 2020 to integrate existing and new sensor technologies in a smaller and more modular body.
