Listen Current: A New Human-like Species

Listen Current

September 22, 2015  --  A new species that tells us something about humans origins was recently discovered deep inside a cave in South Africa. This discovery is a mystery in many ways. How did the bones get there? How old are the fossils? What is the significance of discovering them? The bones are so deep inside the cave they were almost inaccessible. The scientist who discovered them hired thin, non-claustrophobic scientists to descend a steep cliff and then climb through a 7-inch wide crack in a cave to collect over 1,000 bones.

EARTH Magazine: Vital Seconds - The Journey Toward Earthquake Early Warning for All

EARTH Magazine

From EARTH Magazine, 09/17/2015  --  Americans are reminded in September to be prepared for natural hazards during "National Preparedness Month." A major goal of preparedness is to provide early warnings for earthquakes. Earthquake early warning (EEW) is exactly what it says: It is an early warning that shaking is coming and it can typically give a few seconds to a few minutes, at most, of warning. The warnings can be sent off just after an earthquake occurs on a fault, but before the damaging secondary waves are felt. It is not earthquake prediction.

Teachable Moment from IRIS - Magnitude 8.3 Offshore Coquimbo, Chile

IRIS

09/16/2015  --  IRIS does an excellent job collecting and preparing resources we can use in our classrooms on recent, significant earthquakes. Check out their PowerPoint, visualizations and animations on the 8.3 magnitude earthquake that struck offshore Chile late Wednesday.  The earthquake occurred 229km (142mi) north-northwest of the capital Santiago. The earthquake shook buildings in Santiago and generated a tsunami that caused flooding in some coastal areas.  The coastal town of Coquimbo was hit by waves of up to 4.5 meters (15 feet) high after the earthquake.

Press release for students - Hair ice mystery solved

EGU Planet Press

From EGU, 07/22/2015  --  Did you know that there is a type of ice called hair ice? It is shaped like fine, silky hairs and looks like white candy floss. It grows on the rotten branches of broad-leaf trees during humid winter nights when the air temperature drops slightly below 0°C. A 100-year old theory states that hair ice also needs something else to grow – a fungus – but, until now, no one had managed to confirm this.

Listen Current

September 4, 2015  --  It’s been 10 years since Hurricane Katrina flooded New Orleans. At the time then President George W.
