... M8.4 2003 Tokachi-Oki quake off the coast of Japan. The authors estimate ground ... Northwest as having rich energy content. "The expected ground motion may not be very large in amplitude – the peak ...
A new study evaluates expected ground motion in Seattle, Victoria and Vancouver from earthquakes of magnitude 7.5 - 9.0, providing engineers and policymakers with a ...
... 5-5.7 have been previously found to periodically occur on the flanks of Kilauea, and have been identified by ground motion data on Global Positioning System (GPS) stations. A general understanding of ...
Authors explore how ground motion measures scale with magnitude and explore the question: How many earthquakes are there?
... . The USB accelerometers can also mount directly to the floor, which means they will have better sensitivity to ground motions."
So this is not just a neat outreach opportunity—it could one day save ...
... systems, the size of the earthquake can be quickly estimated.
This explanation shows a scaling between ground motion and final earthquake size similar to that observed from seismograms. The authors ...
... used computational simulations to show that the reinforced structure would likely have withstood the ground motion caused by strong earthquakes recorded in the past.
The engineers studied buildings ...
... the response of modern steel 6- and 20-story buildings to the hypothetical ground motions. Although there are many unanswered questions about such a future earthquake, they report that severe damage ...
... series of simulated earthquakes, starting with a 5.0 magnitude and ending with an 8.0. The jolts were based on ground motions measured during the 1994 Northridge, Calif. earthquake, ...
... structural motions. Although rotational effects from earthquakes have been observed for centuries, rotational ground motion has been ignored due to a widespread belief that rotation is insignificant ...
... of the whole process, from knocking on doors notifying residents of the work, to placing the ground motion sensors and interpreting the 3D computer results."
The engineering and geological sciences ...
... force increases the frequency of the oscillator in order to avoid disturbances caused by local ground motion.
While the effort to detect gravitational waves is ongoing, the researchers have now used ...
... ground motions recorded during the 1995 Kobe, Japan, earthquake, magnitude 6.9, and the 1994 ... tests, Deierlein said his group amplified the ground motion shaking from the actual earthquake records to ...
... very precise measurements – down to a scale of a few centimetres – can be made of any ground motion taking place between image acquisitions. Coloured interferograms usually appear as rainbow fringe ...
