NetQuakes
The USGS is trying to achieve a denser and more uniform spacing of seismographs in select urban areas to provide better measurements of ground motion during earthquakes. These measurements improve our ability to make rapid post-earthquake assessments of expected damage and contribute to the continuing development of engineering standards for construction.
To accomplish this, we developed a new type of digital seismograph that communicates its data to the USGS via the internet. The seismographs connect to a local network via WiFi and use existing broadband connections to transmit data after an earthquake. The instruments are designed to be installed in private homes, businesses, public buildings and schools with an existing broadband connection to the internet.

The most recent triggered activity at each seismograph is available online.
Volunteers Needed
We are looking for people who are willing to host these “NetQuakes” seismographs. The NetQuakes seismographs access the internet via a wireless router connected to your existing broadband internet connection. The seismograph transmits data only after earthquakes greater than magnitude 3 and otherwise do not consume significant bandwidth.
To host a NetQuakes instrument, you must provide:
- An out-of-the-way location in a 1-2 story building (no significant basement) with less than ~4000 sq feet in plan; building must have a concrete slab foundation in some location (for example, a garage) to which the NetQuakes box can be bolted. Buildings within a half mile of significant business districts and those near urban or suburban faults (such as the Hayward fault in the East Bay) are highly desirable.
- A local network with a permanent broadband connection to the internet. If you don't have WiFi, we will install a WiFi router.
- AC power to the seismograph.
- Occasional minor servicing of the instrument, such as battery replacement.
Sign Up
Over the next several years we hope deploy many more of these seismographs in several urban areas. We are collecting names and addresses of people who are willing to host one of these seismographs so that as they become available, we will be able to place them in the most effective locations.
Northern California
If you live northern California (especially in the San Francisco Bay area), you can sign up if the location of your home or business is eligible.
Southern California
If you live southern California (especially near dense population centers), you can sign up if the location of your home or business is eligible.
Pacific NW
If you live in the Pacific NW (especially in the Seattle area), you can sign up if the location of your home or business is eligible.
