Sentences with phrase «seismic events of magnitude»

This would be combined real - time monitoring to track the rate of seismic events of magnitude 2 or greater within 25 kilometers, with fracking operations adjusted to potentially reduce this rate to less hazardous levels.

Not exact matches

«We demonstrated that consecutively triggered earthquakes can enhance the amount of energy produced by the ruptures, exceeding the design specifications expected for buildings in moderate seismic hazard zones,» said Tramelli, whose analysis suggests that the shaking from multiple magnitude 5.0 earthquakes would be significantly greater than from an individual magnitude 5.0 event.

Laboratory Models In 1975 Ari Ben - Menahem, a seismologist at the Weizmann Institute of Science in Rehovot, Israel, analyzed the seismic waves triggered by the Tunguska event and estimated that the energy released by the explosion was between 10 and 15 megatons in magnitude, the equivalent of 1,000 Hiroshima atomic bombs.

The seismic events in that supposed grouping, consisting of 3 magnitude 9 or higher temblors, struck Kamchatka, then Chile and then Alaska within a 12 - year interval.

For an event of a particular seismic magnitude, the deeper the explosion, the more energetic the blast.

While low - magnitude seismic events of tectonic origin typically have frequencies of 10 to 20 cycles per second, this shaking was dominated by frequencies of 2 to 4 cycles per second.

During that event, 14 phones in the state triggered, but even this relatively small number of phones allowed the seismology lab to peg the magnitude within 1 percent of estimates from ground seismic stations, and located the epicenter to within 4 kilometers (2.5 miles).

The result is a model that quantifies the distance that an earthquake can propagate beyond an injection site — which in turn predicts the maximum magnitude of an induced seismic event.
