EARTH: Unlocking the Cascadia Subduction Zone's Secrets: Peering into Recent Research and Findings

EARTH Magazine

From EARTH Magazine  --  The Cascadia Subduction Zone is a 1,000-kilometer-long subduction zone stretching from Mendocino, Calif., to north of Vancouver Island off the coast of British Columbia, Canada. Those living along this stretch are occasionally treated to some shaky moments by the subduction of the Juan de Fuca Plate beneath the massive North American Plate. But the real threat is a

EARTH: Parasites spread across the Arctic under the "new normal"

EARTH Magazine

From EARTH Magazine  --  The last several decades have seen Arctic sea-ice minimums drop by more than half in area and more than three-quarters in volume. With current models predicting further reductions, scientists are calling it the "new normal" and are trying to grasp its implications - one of which is the occurrence of pathogens never before seen in the Arctic.

Press release for students - Art reveals secrets about Earth’s past atmosphere

EGU Planet Press

From EGU  --  Christos Zerefos and his team of Greek and German researchers have recently found that the colours of sunsets painted by artists as far back as 1500 can actually tell us how polluted the atmosphere was in the past!

EARTH: Preserving Peru's Petrified Forest

EARTH Magazine

From EARTH Magazine  --  Tucked high in the Andes Mountains of northern Peru is a remarkable fossil locality: a 39-million-year-old petrified forest preserved in nearly pristine condition: stumps, full trees, leaves and all. With its existence unknown to scientists until the early 1990s - and its significance unbeknownst to villagers - this ancient forest hosts the remains of more than 40 types of trees, some still rooted, that flourished in a lowland tropical forest until they were suddenly buried by a volcanic eruption during the Eocene.

NASA's Space Place: The Invisible Shield of our Sun

NASA's Space Place

By Dr. Ethan Siegel - Whether you look at the planets within our solar system, the stars within our galaxy or the galaxies spread throughout the universe, it's striking how empty outer space truly is. Even though the largest concentrations of mass are separated by huge distances, interstellar space isn't empty: it's filled with dilute amounts of gas, dust, radiation and ionized plasma.

Teachable Moment from IRIS - Magnitude 7.9 Rat Islands, Aleutian Islands, Alaska

Magnitude 7.9 Rat Islands, Aleutian Islands, Alaska

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 earthquake (M7.9) that occurred in a remote area of the volcanic Aleutian Islands. The epicenter was located 19 km (11 miles) ESE of Little Sitkin Island, Alaska, while the depth was 108 km below Earth’s surface.

NASA's Space Place: A Glorious Gravitational Lens

NASA's Space Place

By Dr. Ethan Siegel  --  As we look at the universe on larger and larger scales, from stars to galaxies to groups to the largest galaxy clusters, we become able to perceive objects that are significantly farther away. But as we consider these larger classes of objects, they don't merely emit increased amounts of light, but they also contain increased amounts of mass. Under the best of circumstances, these gravitational clumps can open up a window to the distant universe well beyond what any astronomer could hope to see otherwise.
