Sentences with phrase «seismic velocity data»

Key to the team's analysis was seismic velocity data from the U.S. Transportable Array, a traveling grid of seismometers that «listens» for low - level earthquakes and tracks the way their energy passes through the subsurface.

Not exact matches

For their study, the researchers used the latest seismic models of Earth's velocity structure and 35 years of helium data.

Using GPS, InSAR, gravity, seismic reflection, and geological data, Marcos Moreno and colleagues from GFZ as well as Chile show that the 2016 earthquake occurred at the deep boundary of a persistent asperity on the interface between the subducting Nazca and overriding South American plates, where both plates are coupled and not sliding past each other in spite of the high convergence velocity of 68 mm / year.

Using the seismic data, the researchers developed a three - dimensional velocity model of a magma anomaly to determine the size, depth and composition of the lava chamber, which is several kilometers in diameter and located at a depth of 8 - 11 km (5 — 6.8 miles).

We find that the asteroseismic parameters allow us to test cluster - membership of the stars, and even with the limited seismic data in hand, we can already identify four possible non-members despite their having a better than 80 % membership probability from radial velocity measurements.

In preparation for its submission, Canada has acquired about 15,500 kilometres [9,631 miles] of seismic reflection data, 1,100 km [684 miles] of seismic refraction data and 38,000 line - kilometres [23,612 miles] of bathymetric data, as well as deployed 171 sonobuoys to collect information about the seismic velocity in the sedimentary layers.

(1) the band pass seismic data for high - frequency detail, and (2) the velocity - density profile which provides the low frequency information.
