Erroneous earthquake report in Sedona area

Tucson News Now has published a report of a magnitude 4.7 earthquake near Sedona on Sunday night saying they got it from the Associated Press, and quoting the Arizona Geological Survey as the source of information.    However, no such earthquake occurred.

The information and quotes in the release are taken entirely from the news story of the November 30, 2014 earthquake of that magnitude at the location.

We've alerted AP and Tucson News Now of the error and presume they will remove the story from their site.

Here's today's report as published by Tucson News Now -

Rock slab stabilized at Glen Canyon Dam

The 250-ton slab of Navajo Sandstone peeling off the south wall of the canyon at Glen Canyon dam has been bolted into place to prevent it from falling on to power plant facilities immediately below (bottom photo).   The photo below shows the slab in the lower left area of the circle below with dozens of dark circles marking the rock bolts.  [my photo, 10-5-15]

An official at the dam said plans are to remove small pieces of the slab over time to eliminate the threat.

Later that evening, at 9:23 pm, a magnitude 2.9 event occurred about 7 miles SSW of Kachina Village. This could be another aftershock to last November's M=4.8 earthquake between Flagstaff and Sedona.

The region from around Flagstaff to Grand Canyon is the most seismically active in the state.

Expanding the national geothermal data system

We're in the last day of the Geothermal Resources Council annual meeting in Reno, with an exhibit booth in the Geothermal Energy Association's Expo, giving demonstrations of the National Geothermal Data System ( 

AZGS manages the NGDS on behalf of the rest of the state geological surveys, with 65+ data providers in all 50 states contributing over 10 million data records currently. Any geothermal energy project funded by the US Dept. of Energy has to make their data publicly available through the NGDS.   Most projects chose to send their data to the Geothermal Data Repository node on NGDS.  GDR is run by the National Renewable Energy Lab in Colorado. 

We've been meeting with leaders of various research projects in the Play Fairway Analysis and FORGE programs to discuss adding their growing reams of data into NGDS. We've also had conversations with representatives from East African countries about supporting their data management programs for the booming geothermal development in that region. [Right,  AZGS' Steve Richard -right- talks with Andrew Palmateer with the US Energy Association's East Africa Geothermal Program, and Rick Zehner with Geothermal Development Associates, about data needs in East Africa]

Search engine allows access to 19 environmental databases

The Arizona Department of Environmental Quality (ADEQ) announced it now has available through its website an online search engine allowing faster, more direct access to the agency’s 19 environmental databases containing information such as a facility’s operating permits and compliance history.

Known as MegaSearch (, the tool allows customers to enter search criteria such as a facility’s name and address or its unique ADEQ file number to view a list of relevant environmental records and files of interest. Once identified, the files may be selected from the results page and emailed to the ADEQ Records Center for retrieval and viewing. By conducting their own independent research, customers can save time by eliminating the need to wait for results from a traditional records request with the help of Records Center staff.

“MegaSearch helps prospective land and business owners or anyone who wants to see instantly what environmental activity has been reported for a given location,” ADEQ Records Manager Eric Flohr said.

For example, Flohr said if you previously had wanted to know if a nearby gas station had a history of leaking underground storage tanks, you would have contacted ADEQ to submit a research request. Staff would then have accessed these same databases now available online to see what records of activity had occurred at the site. The process could take several days depending on the number of pending research requests, he said.

“Tools like MegaSearch give customers direct and instantaneous access to ADEQ’s vast amounts of environmental data from all over the state, which supports more transparent government for our citizens,” Flohr said.

For questions about MegaSearch, please contact Eric Flohr at (602) 771-4335 or by email at
