[14] [15] It appears that earthquake shaking from induced earthquakes may be similar to that observed in natural tectonic earthquakes, [16] [17] or may have higher shaking at shorter distances. [18] This means that ground-motion models derived from recordings of natural earthquakes, which are often more numerous in strong-motion databases [ 19 ...
A study on possible correlation between large nuclear tests at the Nevada Test Site and earthquakes hundreds of kilometers away in California found no peaks in seismicity at the times of the explosions. [4] A 1968 one-megaton underground nuclear test which was, ironically, named Faultless, caused clearly visible surface slip up to 40 km away. [3]
In 2016, Nederlandse Aardolie Maatschappij funded a team of researchers from Durham University and Newcastle University to conduct a full review of induced seismicity. This review formed part of a scientific workshop aimed at estimating the maximum possible magnitude earthquake that might be induced by conventional gas production in the Groningen gas field.
A report released Monday by the USGS found that man-made earthquakes have increased more than ten times over in parts of the central United States.
Moderately damaging earthquakes strike between New York and Wilmington, Delaware, about twice a century, the USGS said, and smaller earthquakes are felt in the region roughly every two to three years.
The US Geological Survey recently mapped all the places that are most likely to be damaged by human-induced earthquakes in 2016. These 6 states are the most at risk of a human-caused earthquake ...
In its most general sense, the word earthquake is used to describe any seismic event that generates seismic waves. Earthquakes can occur naturally or be induced by human activities, such as mining, fracking, and nuclear tests. The initial point of rupture is called the hypocenter or focus, while the ground level directly above it is the epicenter.
The properties of seismic waves are modified by the material through which they travel. By comparing the differences in seismic waves recorded at different locations, it is possible to create a model of the subsurface structure. Most commonly, these seismic waves are generated by earthquakes or man-made sources such as explosions.
