Volcanoes are complex natural systems, and understanding a volcano’s behaviors requires the attention of specialists from many science disciplines.  It demands a combination of current knowledge about magma systems, tectonic plate motion, volcano deformationearthquakes, gases, chemistry, volcano histories, processes, and hazards.

Floods give new meaning to “car pool lane”.

Unfortunately, winter's 2015/2016 persistent precipitation - accompanied by strong winds and tornadoes in some areas - blanketed two large swaths from Texas to Ohio, and Mississippi to North Carolina. As early flash-flooding began to recede, the nation began 2016 with major floods in the Missouri, Ohio, and Mississippi River basins, setting new winter flood records.

Mount Rainier-Magma Cum Laude?

Not really! Because of its elevation (14,410 f), relief, hydrothermal alteration, icecap, glacier-fed radial valleys, and proximity to encroaching suburbs of the Seattle-Tacoma metropolis, Mount Rainier is the most threatening volcano in the Cascades.  Its next eruption could produce volcanic ash, lava flows, and avalanches of intensely hot rock and volcanic gases, called pyroclastic flows.

Have you kissed a frog lately?

First you may want to make sure it is not a toad. Toads have a poison gland behind their eyes with a chubby body and shorter legs. Amphibians are ecologically important for several reasons. They are critical predators of invertebrates, helping to stabilize insect populations, and they serve as prey to other animals, such as birds. Amphibians are also indicator species; that is, they are sensitive to specific environmental factors and their fate can help predict the health of the ecosystem. Scientists are only beginning to realize the potential amphibians have for providing potentially lifesaving medicines to fight infections.
