AZGS deploys broadband seismometers - from the North Rim to Douglas - to monitor earthquake activity in Arizona and environs.
Arizona & environ
Area of Study
Where and when will the next major earthquake occur in Arizona? How much damage will it do? Will people be injured? The AZGS is tasked with addressing those very real concerns. For an illustrated, non-technical primer, see Arizona is Earthquake Country - http://repository.azgs.az.gov/uri_gin/azgs/dlio/1459.
In 2009, and with nearly $500,000 in funds from the Federal Emergency Management Agency (FEMA), the AZGS adopted eight seismometers deployed across the state as part of NSF's Earthscope program; thus establishing Arizona's first statewide seismic network. New broadband seismometers were added recently, bringing to 13 the number of seismic stations deployed as part of the Arizona Broadband Seismic Network (ABSN).

NEHRP direct state funding teleconference
AZGS participated today in FEMA's National Earthquake Hazard Reduction Program Earthquake Program Managers teleconference. FEMA reinstated direct NEHRP funding to the states in 2017-2018. Arizona was one of 14 states to participate last year. Today's meeting was to review state participation for the next fiscal year.

Basin & Range Province Earthquake Working Group - Update
The Basin and Range Province Earthquake Working Group met Thursday 2/15 in Salt Lake City. The Utah Geological Survey hosted the meeting and the USGS Earthquake Hazards Reduction Program provided financial support, which allowed representatives from all the Intermountain West states (including AZ) to attend. The primary purpose of the meeting was to share information and ideas about improving the science behind earthquake hazard assessment in the Basin and Range Province.
Much more research and investigations into Quaternary faulting have been completed in some states (Utah, California) than in the rest of the Intermountain West. We look to them as guides for future earthquake research, integrating research into seismic hazard assessments, and disseminating information about earthquake hazards to the public.

AZGS Broadband Network records M7.9 earthquake
AZGS seismic stations were among 300+ stations that provided insight into the precise location of today's M7.9 Alaskan earthquake. The NEIC/USGS used data from our stations at Grand Canyon's North Rim, Tonto, Hannagan Meadow, Duncan, and Douglas. Seismograms from AZGS stations (Jeri Y-BH).
