Sentences with phrase «because larger quakes»

Not exact matches

Because scientists have evidence in the prehistoric record of quakes that large in the Texas - Oklahoma region, the USGS's new maps include a low - probability chance for that possibility.

Estimating magnitude for larger quakes also takes more time, because the rupture of the fault lasts perhaps several seconds longer — a significant chunk of time when it comes to EEW.

Their interest is more than purely academic, because triggered tremors - if that is what they are - may warn that a really large quake is on the way in the same place.

At the original trial, many witnesses described how their loved ones had been persuaded to stay indoors after De Bernardinis told a journalist, during a now infamous interview ahead of the commission's meeting, that the ongoing tremors were favorable because they discharged energy and therefore made a larger quake less likely.

That's because the larger surface - wave magnitudes record low - frequency energy, while Richter and coda magnitudes are based on high - frequency seismic waves that people usually feel during real quakes.

But because a fault system can only release as much energy as is built up by grinding tectonic plates, increasing the frequency of large events means there will be less energy to fuel smaller quakes.

Because the faults that break during the earthquake are so deep, the seismic wave energy they radiate spreads over a much larger area than in a shallow quake.

Detecting glacialquakes is important because glaciers appear to accelerate after large calving events.2 The frequency of glacialquakes — which has been rising since the late 1990s — has increased particularly since 2002.3 In fact, the number of quakes in 2005 was twice that of 2001.1 In late summer of 2005, glacial seismic activity was almost five times greater than in the winter months — most likely owing to seasonal changes in temperature.1, 3
