Document Description
This new station will contribute to the CA Earthquake Early Warning System designed to potentially save thousands of lives during a large earthquake, prevent critical infrastructure damage and expedite recovery following a large earthquake. The network to which this sensor is connected will contribute real-time data to accurately record and warn people of strong shaking due to earthquakes in the region, and help provide records of ground motion that would be of immense scientific, engineering and public safety value. Under a ten-year lease with property owner, UC BSL plans to install and operate an outdoor seismic monitoring station at the Lat/Long location noted. Three-day installation will take place in a roughly 36 sq. ft. area, to install two small structures: Grounding rods will be insert next to the equipment to protect the site from lightning strikes. Holes for the vault, solar panel mount, and antenna and fence poles will be dug by a small backhoe or hand-operated auger. Access to site is entirely by existing roads and trails. There are no hazardous substances involved. If needed, a small generator will be used to power a hand loaded concrete mixer and any other tools needed for the work.
