seismicity

基本解釋

More recently, researchers have sought to associate electromagnetic fields, the radon or hydrogen content of the soil and seismicity patterns with impending earthquakes.
最近，研究者們試圖將電磁場以及土壤中氡和氫的含量與將要發(fā)生的地震類型聯(lián)系在一起。
Many scientists believe this link between temblors and dams—called reservoir-induced seismicity—may have been what happened at California's Oroville Dam, in the foothills of the Sierra Nevada.
很多科學家都認為地震和大壩之間是有聯(lián)系的，他們稱其為“水庫引發(fā)地震”，這種地震已在位于美國內(nèi)華達山脈山麓下的加利福尼亞州奧羅維爾壩附近發(fā)生過。
"There has been seismicity but not really great-earthquake seismicity," says Hiroo Kanamori, a seismologist at the California Institute of Technology in Pasadena.
“仙臺曾經(jīng)發(fā)生過地震，但是卻沒有發(fā)生過強烈大地震，”麻布金森說，他是美國帕薩迪納加州理工學院的地震學家。

What is known about past large Himalayan earthquakes, what is uncertain, and where are the gaps in knowledge and in seismicity where large and destructive events could occur in the foreseeable future?
