University of Pennsylvania: Penn Research Helps Paint Finer Picture of Massive 1700 Earthquake
Researchers from the United States and Canada used a fossil-based technique of investigation to provide a finer-grained portrait of a massive earthquake and tsunami that hit the Pacific Northwest coast of the United States in the year 1700. Understanding the changes in coastal land level produced by the estimated 9 magnitude earthquake will help citizens and government to better prepare for future large earthquakes.

Mother Nature Network: Which U.S. volcanoes are likely to erupt next?
There are three main sections of the U.S. that tend to experience volcanic activity, and scientists believe many of the volcanoes there may be about due for a major eruption. Seven U.S. volcanoes (including four in Washington State) pose some of the highest risks.

University of AlbertaHelping forests gain ground on climate change
Timber industry and government foresters are using tree-planting guidelines developed by University of Alberta researchers to get a jump on climate change. Researchers also have developed maps of likely climatically suitable habitats for tree species based on climate predictions for the 2020s through 2080s.

Deep Carbon ObservatoryPresence of Life in Oceanic Crust Confirmed
Researchers have discovered evidence of life 500 meters below the seafloor of the Juan de Fuca Ridge. “They found genetic evidence of Methanosarcinales, anaerobic archaea known to metabolize methane. Further experiments showed that microbes have affected the chemical signature of sulfur in the host basalt, suggesting they could harness energy from the breakdown of sulfates.
