测量地震和海啸的大小似乎已经确立,但其内容並不那么简单,对于地震和海啸这样复杂的天然现象,其物理量怎样定量和测定,作为一种概念来说虽然陈旧,但内容常常更新。过去,作为表示地震大小的尺度,主要采用烈度和震级(M)。烈度就是将地震对人体 Measuring the size of earthquakes and tsunads seems to be well established, but its content is not that simple. The quantitative and quantitative measurements of the physical quantities of complex natural phenomena such as earthquakes and tsunamis, though dated as a concept, are often updated. In the past, as a measure of magnitude of the earthquake, intensity and magnitude (M) were mainly used. Intensity is the earthquake on the human body
