New research suggests this liquid magma is very rare. That’s an important finding for researchers trying to predict when a volcano may erupt.</span></p><p> Mon, 17 Feb 2014 15:47:59 +0000 Courtney Flatt 41576 at http://nwpr.org Volcanic Eruptions Could Be More Rare Than You Think Colombians Urge Pacific Northwesterners To Appreciate Lahar Danger http://nwpr.org/post/colombians-urge-pacific-northwesterners-appreciate-lahar-danger <p></p><p><span style="line-height: 1.5;">Visiting scientists from the country of Colombia have a warning for people living in the valleys below our Northwest volcanoes.

Undersea Volcano Erupts Off Northwest Coast http://nwpr.org/post/caught-tape-undersea-volcano-erupts-northwest-coast <p>For the first time, we&#39;re getting to listen to the eruption of an undersea volcano off the Northwest coast. Correspondent Tom Banse got a hold of unusual recordings made at a place called Axial Seamount. It&#39;s about 300 miles out to sea from Cannon Beach, Oregon.

Hood doesn&rsquo;t erupt with the same bang and violence as other Cascade volcanoes. Amelia Templeton reports. Wed, 15 Feb 2012 15:09:25 +0000 Amelia Templeton 3179 at http://nwpr.org Why Mt.
