In the typical textbook picture, volcanoes, such as those that are forming the Hawaiian islands, erupt when magma gushes out as narrow jets from deep inside Earth. But that picture is wrong, according to a new study.
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.
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 is embarking on four research programs that intend to produce clean energy, probe the bizarre phenomena of quantum physics, understand the genetic and neural wiring behind complex behaviors, and save lives during earthquakes. To support these projects, the Gordon and Betty Moore Foundation recently allocated a total of $17.5 million, part of the Foundation’s $300 million commitment made to Caltech in 2001.
On October 21 at 10:21 a.m., businesses, nonprofits, schools, governments, neighborhoods, organizations, families, and others throughout the state will practice the "Drop, Cover, and Hold On" protocol as part of the Great California ShakeOut statewide earthquake drill.
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.
Scientists at the California Institute of Technology (Caltech) have demonstrated that high-speed intersonic ruptures exist and could occur during the next major earthquake. The researchers now have the ability to create laboratory earthquakes of varying force and magnitudes that mimic actual quakes. By triggering laboratory earthquakes, researchers can study the behavior of quakes and their potential force and destructiveness—without a real quake actually occurring.
