What are earthquakes? Gain a new perspective on these powerful phenomena with an e-book and iTunes U course co-produced by the California Academy of Sciences and KQED.
When a megathrust earthquake strikes, scientists around the world know in seconds. But what about hundreds of years ago? How, exactly, do scientists know there was a megathrust quake on the Cascadia Subduction Zone on January 26, 1700 between 9:00 and 10:00 p.m.? The answer lies in a ghost forest discovered on the Washington coast that reveals the secrets of one of the most powerful earthquakes to hit the planet.
"Minuscule" amounts of iodine-131 was found in milk from Washington state.
On March 12, a one-foot tidal wave was filmed as it slowly surged across the San Francisco Bay. The wave traveling 5000 miles from Japan started out as a 23-foot tsunami off the Japanese coast.
One tool to remind ourselves of what is possible when it comes to 'rare' natural events is science.
The magnitude 7.0 earthquake that occurred a couple weeks ago near Christchurch, New Zealand is yet another reminder for those of us living in the Bay Area about the inevitable seismic danger we face. While many details of the New Zealand earthquake are different than what we face in the Bay Area, there are a few aspects that are comparable.
On January 26, 1700, at about 9:00 p.m. Pacific Standard Time one of the largest earthquakes ever to strike the Pacific Northwest rumbled across the Cascadia Subduction Zone. This massive earthquake sent a giant 33 foot high tsunami crashing onto shore, inundating the quiet coastline.
We heard about the Monterey Bay Aquarium Research Institute's new underwater laboratory in a radio story last fall. When that story aired, the lab (known as the Monterey Accelerated Research System, or MARS) was just getting going, with lots of neat experiments planned. Now, few of those have become a reality.
So we know- or should know- the seismic risks of living in one of the most vibrant, diverse places in the U.S. Short of leaving the region, what can we do?
I had the privilege this week of interviewing Isabel Hawkins, an astronomer and director of the Center for Science Education at Berkeley's Space Sciences Laboratory. We talked about how people use evidence in science, how it is that we know what we know. Hawkins isn't your ordinary astronomer. She began her career in an ordinary […]
