Seismologist reflects on his firsthand experience of the Japanese earthquake

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

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.

Simons Argues Against Hazard Prevention Cuts

Less than two weeks after a 9.0 earthquake and tsunami devastated a large swath of Japan, Caltech geophysicist Mark Simons calls attention to federal budget proposals that would cut funding for prevention technologies.

Seismic Imaging Provides Bigger Picture for Earthquake Researchers

Caltech scientists and students are among a group of government and university researchers collecting seismic images of the Imperial and Coachella Valleys this week.

"Like It or Not, We Are Living on This Planet"

The number of large destructive earthquakes in 2010, plus a flurry of medium magnitude quakes in California, led many people to ask, Are we in a period of heightened temblor activity, and is it likely to continue? E&S sat down with Hiroo Kanamori, the Smits Professor of Geophysics, Emeritus, and Joe Kirschvink, the Van Wingen Professor of Geobiology, to hear their thoughts.

Caltech Geobiologists Uncover Links between Ancient Climate Change and Mass Extinction

About 450 million years ago, Earth suffered the second-largest mass extinction in its history—the Late Ordovician mass extinction, during which more than 75 percent of marine species died. Exactly what caused this tremendous loss in biodiversity remains a mystery, but now a team led by researchers at Caltech has discovered new details supporting the idea that the mass extinction was linked to a cooling climate.

New Flume On the Block

Last Wednesday morning, Caltech received a rather large delivery. About 50 feet long and 5 feet wide, a big black chunk of metal was unloaded from a truck and slowly pushed into the Central Engineering Services Building.

Thomas J. Ahrens, 74

Thomas J. Ahrens, the Fletcher Jones Professor of Geophysics, Emeritus, at Caltech, died at his home in Pasadena on November 24. He was 74.

 

Recent News on the Debate over Pluto's Planethood

Earlier this month, Eris—the distant world first discovered by Caltech's Mike Brown and colleagues back in 2005, paving the way for the eventual demotion of Pluto from planet to dwarf planet—passed fortuitously in front of a faint star in the constellation Cetus. That passage, or occultation, allowed the first direct measurement of Eris's size.

Caltech Receives $10 Million in Gifts to Help Launch New Terrestrial Hazard Center

Caltech has established the Terrestrial Hazard Observation and Reporting Center (THOR), funded by $6.7 million from Foster and Coco Stanback, and $3.35 million from the Gordon and Betty Moore matching program.
