Environment - Earthquakes by magnitude 1960–2023

The following statistics on the frequency and magnitude of New Zealand region earthquakes are based on observations since 1960. Statistical analysis was restricted to earthquakes with a magnitude greater than or equal to 4.0, as the geometry of the recording networks in the earlier years was not capable of detecting every earthquake lower than this magnitude.

以下关于新西兰地区地震频率及震级分布的统计数据，基于自1960年以来的观测数据。统计分析仅限于震级大于或等于4.0的地震，因为早期年份的记录网络几何结构无法检测到低于此震级的每一场地震。
