History of Kelunji Seismographs
"Kelunji" is an Aboriginal word for a small cockatoo known locally as a "galah" - also an Australian euphemism that reflects some traits of our seismologists 😉
Starting in the late 1970s, our first generation digital recorders, the Alpha and Beta, used cassette tapes for triggered data recording. The first recorder known as "Kelunji" is now referred to as the Classic, and was our first to use solid state memory (1MB!). This was followed by the D-series and 24-bit Echo that used high volume CompactFlash Card storage, with the EchoPro (and briefly Fusion) moving to USB data storage. Following the ABCDEF nomenclature, our 7th generation "G" recorder recalls the Echo name and its core values of user-friendliness and continuous recording.
Of course our latest recorder needed to use the latest technology, which includes 32-bit ADC chips and other components that enables the Gecko to use a fraction of the power of previous generation machines.
As always, the Gecko supports sensors from any and all manufacturers: be they geophones or microphones; blast or earthquake accelerometers; or short period to broadband seismometers.
Our technology doesn't end at the recorder - we have developed data telemetry solutions, network management and data display software, and data analysis and alerting applications. The Gecko is just the first step in the complete seismic monitoring solution developed by the Seismology Research Centre and manufactured by ESS Earth Sciences.
