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.

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.

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.

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 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.

Using a diamond-anvil cell to recreate the high pressures deep within the earth, researchers at the California Institute of Technology (Caltech) have found unusual properties in an iron-rich magnesium- and iron-oxide mineral that may explain the existence of several ultra-low velocity zones (ULVZs) at the core-mantle boundary. A paper about their findings was published in a recent issue of Geophysical Research Letters (GRL).

Computational scientists and geophysicists at the University of Texas at Austin and Caltech have developed new computer algorithms that for the first time allow for the simultaneous modeling of the earth's mantle flow, large-scale tectonic plate motions, and the behavior of individual fault zones, to produce an unprecedented view of plate tectonics and the forces that drive it.

In an announcement August 13, the National Research Council recommended three space- and ground-based astronomy and astrophysics projects with potential major roles for researchers at Caltech: CCAT, a giant submillimeter telescope that will help unravel the origins of stars, planets, and galaxies; LISA, designed to detect gravitational waves; and the development of a Giant Segmented Mirrored Telescope—the Thirty Meter Telescope being one of two such telescopes under development.
