Anyone with an Internet connection can now find out whether the house they want to buy is on one of California’s earthquake faults.
The California Geological Survey announced that it was posting its fault zone maps online for the first time. The 547 maps were previously available only in paper or CD formats.
California state geologist John Parish says the agency uses Google Maps’ address-matching technology to link users to the right map for a property’s location.
State law already requires home sellers to disclose to buyers whether a home is in an earthquake fault zone.
