EARTH: We're All Living in the Aftershock Zone

EARTH Magazine

From EARTH Magazine  --  When large earthquakes hit Earth in quick succession, many people wonder if the events are linked. Scientists generally say that such events aren't linked, but the latest research seems to indicate that a large earthquake can potentially trigger another quake hundreds or even thousands of kilometers away in a process called dynamic triggering. However, when it could happen is far from predictable.

Listen Current: Indonesian Cave Paintings

Listen Current

This story, about the discovery of ancient cave paintings in Indonesia would be a great starting point for a discussion of human origins and geology. Cave painting has long been thought to be developed by early humans in Europe. This discovery in Indonesia is pushing scientists to look even farther back to our human origins in Africa.

Teachable Moment from IRIS- Magnitude 7.3 Offshore El Salvador, 10/14/14


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 this powerful magnitude 7.3 earthquake, which struck off the Pacific coast of Central America late Monday night. Early reports indicate one death.The earthquake occurred at a depth of 40 km (24.9 miles).  Its epicenter was offshore, 86 km (53 miles) SSW of La Union, El Salvador.

EARTH: Kilauea eruptions could shift from mild to wild

Hawaii's Kilauea volcano is famously effusive: Low-viscosity lava has been oozing out of the main caldera and two active rift zones along the southern shore of the Big Island since 1983. But scientists suspect that Kilauea's eruptions haven't always been so mild. In the past 2,500 years, at least two cycles of explosive eruptions lasting several centuries each have rocked the island. The switch from effusive to explosive is likely to occur again, scientists say, but probably not anytime soon.

NASA's Space Place: Where Does the Sun's Energy Come From?

NASA's Space Place

This month, the Space Place is doing something a little bit different for their monthly column—providing you with a beautifully informative and educational poster (attached below) about the mechanics of our sun. This poster accompanies their latest "Space Place in a Snap" animation. This "Snap" series is a set of narrated videos and posters that, together, explain basic scientific concepts in a dynamic new medium. Entertaining in their own right, they also wish to bring this new resource to your attention as an educational tool.

Teachable Moment from IRIS- Magnitude 7.1 Southern East Pacific Rise, 10/09/14

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 this powerful magnitude 7.1 earthquake near the intersection of the Pacific, Nazca and Antarctic Plates. The epicenter was located ~3000 km off the Chilean coast and occurred on October 9, 2014.

EARTH: How the Spanish Invasion Altered the Peruvian Coast

EARTH Magazine

From EARTH Magazine  --  When Francisco Pizarro landed in Peru in 1532, his band of Spanish conquistadors set off a chain of far-reaching consequences for the people and economics of western South America. The Chira Beach-Ridge Plain in northwestern Peru is rippled by a set of nine ridges — several meters tall by up to 300 meters wide and 40 kilometers long, and large enough to be visible from space — running parallel to the shoreline. The pattern, observed along at least five other Peruvian beaches, was thought to have formed naturally over the past 5,000 years.
