- Latest Developments in VBB Deployment | Presentation/Poster
Broadband seismology has changed radically over the last 30 years, from researchers with a large seismological apparatus in their basement vaults to deploying a very broadband seismometer on an Antarctic ice sheet in the brief time it takes to shut off and restart a helicopter! The introduction of new instrumentation that is miniaturized and ruggedized reduces the logistics costs for deploying the lowest noise , very broadband sensors making new approaches affordable and possible. Could a researcher ever conceive of an experiment that could deploy the equivalent of an STS-1 in a temporary array? Broadband vendors continue to evolve and miniaturize traditional force feedback systems to enable researchers to create cost-effective early earthquake warning networks, continental scale rolling arrays, observe glacial seismics and record the ringing of the earth. The newest sensors can have the next logical step in integration from the digitizer to multiple instruments with combined dynamic ranges greater than 200dB. And the next iteration? Geodetic tilt? Atmospheric pressure? We discuss the latest developments that free researchers to deploy new arrays in even the harshest terrestrial conditions by reducing the limitations of the older systems and improving the noise performance, reliability and required logistics support while reducing the complexity.
