In seismology, strong ground motion is the strong earthquake shaking that occurs close to (less than about 50 km from) a causative fault. The strength of the shaking involved in strong ground motion usually overwhelms a seismometer, forcing the use of accelerographs (or strong ground motion accelerometers) for recording. The science of strong ...
Movement is sinistral (left-handed) if the block on the other side of the fault moves to the left, or if straddling the fault the left side moves toward the observer. Movement is dextral (right-handed) if the block on the other side of the fault moves to the right, or if straddling the fault the right side moves toward the observer. [4]
The intensity of local ground-shaking depends on several factors besides the magnitude of the earthquake, [3] one of the most important being soil conditions. For instance, thick layers of soft soil (such as fill) can amplify seismic waves, often at a considerable distance from the source.
Officials in New York City say a 1.7 magnitude earthquake shook parts of Queens and Roosevelt Island on Tuesday morning, not an explosion.. Around 5:45am, the FDNY received reports of buildings ...
Ground vibrations is a technical term that is being used to describe mostly man-made vibrations of the ground, in contrast to natural vibrations of the Earth studied by seismology. For example, vibrations caused by explosions, construction works, railway and road transport, etc. - all belong to ground vibrations.
Frederik J. Simons, a professor of geosciences at Princeton University, told NBC News that the earthquake occurred on a shallow fault system in New Jersey and shook for about 35 seconds.
Abed joins Pelton with the giant hand on the RV's roof. As they sit there, the straps suddenly slip. Pelton panics, but Abed uses a flashback to imagine himself convincing the group to use thicker straps. This does not change the current situation, though, and the hand falls off the RV. The rest of the group runs outside to see what happened ...
The driver of the RV was taken to a hospital in critical condition. ... Driver injured when RV hits house, starts fire in southwest Fort Worth. Lillie Davidson. January 10, 2025 at 5:09 PM.
