seismicity

基本解释

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生的地震類型聯系在一起。
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.
很多科學家都認爲地震和大垻之間是有聯系的，他們稱其爲“水庫引發地震”，這種地震已在位於美國內華達山脈山麓下的加利福尼亞州奧羅維爾垻附近發生過。
"There has been seismicity but not really great-earthquake seismicity," says Hiroo Kanamori, a seismologist at the California Institute of Technology in Pasadena.
“仙台曾經發生過地震，但是卻沒有發生過強烈大地震，”麻佈金森說，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?
