AZGS and the 3 public universities receive nearly $500K from FEMA to construct a broadband seismic network in Arizona for monitoring seismicity and evaluating real seismic risk that should lead to better hazard mitigation.
Geology graduates get starting salary offers of $80K per year, rising to $100K as the demands from resource companies heat up.
Resolution Copper announces a $652 million assessment of the proposed mine near Superior.
Riding the metals rollercoaster -- copper (metals) industry sees record highs -- over $4.00 USD per lb in July – to lows – about $1.30 per lb as the year closes. Mining plans are shelved or cancelled, hundreds of miners are laid off.

The first resource assessment of the potash deposit near Holbrook Arizona finds as much as 2.2 billion tons in place, an increase in total U.S. resources by about one-third. Depending on mining methods, the tenfold increase in potash prices puts a value on the deposit of perhaps more than a trillion dollars.

Havasu Falls – 16 August flood damages water falls and hiking trails in Cataract and Havasu canyons. No injuries but repairs estimated at over $2.0 million.
Interest grew in geothermal resources culminating in a new Western US plan for leasing on public lands, although some of the most prospective lands in Arizona are left out.
USGS reports more than 100 naturally occurring deposits of asbestos in Arizona.
Climate modeling indicates the desert southwest will be particularly hard hit by global warming, with longer droughts and more extremes in rainfall.
