Paluweh/Rokatenda Volcano erupts pyroclastic, not lava, flow

The Paluweh Volcano, also referred to as the Rokatenda Volcano, has been busy since late 2012.  This stratovolcano, located in Indonesia, just erupted in early August of 2013, killing at least five people.  Unfortunately, many news media outlets are characterizing the most recent eruption as a lava flow, which is scientifically inaccurate.  The eruptive behavior is that of a pyroclastic flow.  To read the past and present history of Paluweh/Rokatenda, please visit:

Daylighting Takes Off as Cities Expose Long-Buried Rivers

Daylighting Takes Off as Cities Expose Long-Buried Rivers

The latest trend in urban renewal involves opening up underground streams. There's likely an underground stream in your city, but it may soon be seeing the light. Uncovering buried streams has had huge impacts in places as diverse as Seattle, Washington, Kalamazoo, Michigan, and even Seoul, Korea—improving local water quality, providing habitat for fish and birds, and turning neglected parking lots and roads into public parks that boost neighbors' property values and can revitalize entire cities. And city planners everywhere are starting to take note.

Scientists look into Earth's "Deep Time" to predict future effects of climate change

Scientists look into Earth's "Deep Time"

Climate change alters the way in which species interact with one another--a reality that applies not just to today or to the future, but also to the past. "We found that, at all time scales, climate change can alter biotic interactions in very complex ways," said paleoecologist Jessica Blois of the University of California, Merced, the study's lead author. "If we don't incorporate this information when we're anticipating future changes, we're missing a big piece of the puzzle."
