Listen Current: Oklahoma Earthquakes

Listen Current

From Listen Current, 12/09/2015  --  Oklahoma has experienced more than 5,000 earthquakes this year. Some scientists tie these earthquakes to fracking, the extraction of oil and gas from deep within the earth. Fracking uses water to extract the oil and gas and is then injected into underground wells for storage. This can put pressure on faults and cause them to slip and trigger an earthquake. After inspections were ordered, state regulators shut down the water disposal wells, which slowed the earthquakes. But once the wells came back online the earthquakes started again.

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.
