Giving a Tour of USGS Science Center
On March 25th, 2019, ocean engineer Rob Wyland of the Pacific Coastal and Marine Science Center gave a tour and demonstration to roughly a dozen students from the engineering class he teaches at Cabrillo College, a local community college.

A 50-Year Flooding Flashback
The high-water marks set by the Big Sioux River in cities across southeastern South Dakota have threatened to overtake records set 50 years ago, when the Army Corps of Engineers led missions to document the damage through hundreds of aerial photographs.

small amounts of sulfur dioxide
Only small amounts of sulfur dioxide (SO2) and hydrogen sulfide (H2S) are currently being released from Kīlauea, but they chemically react with each other (oxidation-reduction reaction) to form the bright yellow sulfur deposits visible on the crater walls within Halema‘uma‘u.

Earthquake swarms at Mount St. Helens
Graphic shows the earthquake swarm from June-July, 2019, compared to previous swarms detected in March 2019, 2017, 2016, and in 2014. The activity is likely the result of small-scale underground movements of hydrothermal fluids or gas — a sign that Mount St. Helens remains an active volcano.

3D Model of Pu`u `Ō`ō
This 3D model of the Pu‘u ‘Ō‘ō crater was constructed from thermal images taken during a recent helicopter overflight. White areas show warm spots in the crater. Despite the absence of active lava in Pu‘u ‘Ō‘ō, changes at the crater have continued since magma drained from beneath it on April 30, 2018.
