Netquakes: Map of Instruments
The USGS is trying to achieve a denser and more uniform spacing of seismographs in select urban areas. To accomplish this, we developed a new type of digital seismograph that transmits data to USGS via the internet after an earthquake. The instruments are designed to be installed in private homes, businesses, public buildings and schools. Learn more about how you can help.
