The Chikyu allows scientists to gather and study data about seafloor sediments as soon as they are collected. After a powerful 9.0 earthquake triggered a devestating tsunami in Japan in March 2011 ,...
Using maps and graphics, Smithsonian geologist Dr. Liz Cottrell provides an overview of the major earthquake and tsunami that struck Japan on March 11, 2011—one of the largest ever recorded globally...
Superheated magma, about 2,200 degrees Fahrenheit, glows orange as it slowly leaks from cracks along the six-mile long active rift zone of the West Mata Volcano in the Pacific Ocean near Fiji. The...
The foot-long extinct shark Falcatus falcatus lived during the early Carboniferous period around 325 million years ago. The species, known from fossils in the Bear Gulch formation of Montana , was...
Dampier explored this area of Western Australia and named it Shark Bay because of the "abundance" of sharks in the waters. It is now a World Heritage site. Learn more about Dampier's voyages around...
An underwater archaeological stratigraphy reveals the different levels of soil in Hare Harbor, Quebec. The stratigraphy – a process archeologists use to help date materials by identifying soil layers...
A volcanic eruption of superheated magma (some 2,200 degrees Fahrenheit) from the West Mata Volcano produces a bright flash of hot magma that is blown up into the water before settling back to the...
Drilling near the North Pole, Dr. Jan Backman reveals a brief moment in time when the Arctic was subtropical. More about world climate change can be found in our Climate Change featured story .
During the late Cretaceous period, Kansas was covered by a vast sea. There, scientists have found fossils of Squalicorax sharks (also called crow sharks) that lived 70-80 million years ago. They were...
There are different types of beaches and multiple factors that influence the formation of sand. Many beaches may look alike, but they are actually very different from each other. Wave patterns,...

On August 23, 2011 a magnitude 5.8 earthquake struck the East Coast of the United States. The earthquake map shown here, generated by the U.S. Geological Survey and regional seismic network operators...
These star-shaped grains of sand, collected from southern Japan, look like miniature works of art -- but they were not sculpted by an artist. They are the shells of microscopic organisms called...
These deep-sea sediment cores were drilled from beneath the seafloor, and hold information about millions of years of ocean and atmospheric chemistry. As dirt, dead organisms, and other particles...
Geologist Charles Paull (Monterey Bay Aquarium Research Institute) investigates geologic features similar to pingos (Earth covered ice mounds found in the Arctic) on the Arctic Ocean floor where...
In this episode of the Podcast of Life , host Ari Daniel Shapiro dives deep to discover a white worm as tall as your refrigerator that breathes through bright red feathery "lips." This isn’t a...
On August 23, 2011 a 5.8 earthquake emanated from the little-known Central Virginia Seismic Zone. The epicenter was near Mineral, VA, but the tremor shook homes, schools, and office buildings in...
The West Norwegian Fjords - Geirangerfjord and Nærøyfjord site was inscribed on the World Heritage List in 2005. The site's two fjords, among the world's longest and deepest, are considered...
