地震活动对大气与海洋环境变化的影响分析——以美国加州与日本3·11地震为例

Analysis of the impact of earthquake for the atmosphere and ocean——Based on the California and Japan 3·11 earthquake

通过美国加州林火期间的地震、CO气体监测等数据的统计分析,认为地震对气候干燥、林火的发生以及CO气体浓度变化存在重要影响;对比分析日本3·11地震前后的海洋表面温度变化,认为海底地震的热能释放是导致海水温度升高及海洋热膨胀的重要因素,并进而通过海气交换对大气圈等产生影响;综上分析认为,地震活动伴随有大量的热能及气体释放,并对地球系统的多个方面产生影响,在全球变化中具有重要作用。

Through the statistical analysis of data record about the earthquake, wildfire ana CO column concentration, it can be found that the earth＇quake has important influence on the dry climate, wildfire and the variation of CO concentration; Compare the change of sea surface temperature after the 3 ~ 11 earthquake of Japan, the heat energy released by subma- rine earthquake was improved as an important factor for the improvement of ocean tempera- ture and thermal expansion, and also influence the atmosphere indirectly. All the analysis show the earthquake has many impacts on the earth and plays an important role in the global change.
