Hi Mark. To the best of my knowledge there are no magnetic sites maintained by USGS in the Gilroy area. There is one however at Parkfield.

There is however a ELF site located in Gilroy. These will cover about a 20 mile area. It is sponsored Stellar Solutions. The one that is currently being used in the Hayward area is being moved. BART is creating too much of a disturbance.

There is a contact link that you can use to ask questions about the equipment and how to use it.

As of right now there is nothing showing for the Gilroy area. Take Care…Don in creepy town
