Science in Progress: The Curious Case of the Shuram Excursion

Marcus Woo

Caltech geologists John Grotzinger and Woody Fischer have been puzzling over a surprising and controversial discovery made in the early 1990s—a discovery that provided some clues as to what might have caused a sudden burst of biodiversity 540 million years ago.

Caltech Researchers Use GPS Data to Model Effects of Tidal Loads on Earth's Surface

Katie Neith

For many people, Global Positioning System (GPS) satellite technology is little more than a high-tech version of a traditional paper map. Used in automobile navigation systems and smart phones, GPS helps folks find their way around a new neighborhood or locate a nearby restaurant. But GPS is doing much, much more for researchers at the California Institute of Technology (Caltech): it's helping them find their way to a more complete understanding of Earth's interior structure.

New Caltech Research Suggests Strong Indian Crust Thrust Beneath the Tibetan Plateau

Katie Neith

For many years, most scientists studying Tibet have thought that a very hot and very weak lower and middle crust underlies its plateau, flowing like a fluid. Now, a team of researchers at the California Institute of Technology (Caltech) is questioning this long-held belief and proposing that an entirely different mechanism is at play.

Eminent seismologist Hiroo Kanamori, Caltech's Smits Professor of Geophysics, Emeritus, has been studying the movement of the earth his entire career. On March 11 he was in Tokyo, experiencing firsthand the largest earthquake in the country's recorded history.

Warm Water Causes Extra-cold Winters in Northeastern North America and Northeastern Asia

Warm Water Causes Extra-cold Winters in Northeastern North America and Northeastern Asia

Marcus Woo

Average winter temperatures in northern Europe are at least 10 degrees Fahrenheit warmer than similar latitudes on the northeastern coast of the United States and the eastern coast of Canada. The same phenomenon happens over the Pacific, where winters on the northeastern coast of Asia are colder than in the Pacific Northwest. Researchers at Caltech have now found a mechanism that helps explain these chillier winters—and the culprit is warm water off the eastern coasts of these continents.

Caltech's Kate Hutton on the New Zealand Earthquake

Lori Oliwenstein

In the wake of Monday's magnitude 6.3 earthquake in New Zealand--an aftershock of a 7.0 quake in September 2010--reporters looked to Caltech's experts for information and insight. They got both from staff seismologist Kate Hutton, who spent Tuesday afternoon fielding questions from a steady stream of reporters and camera crews.
