Today we talk Earthquakes!
The list of EQ dating back to antiquity is shocking. The amplitude and deaths caused are estimated, but a glimpse of this list is very sobering. Below is a list of some of the important and more recent.
It’s also appropriate to talk about the exponential scale. The richter scale is outdated and really measures the amplitude and distance the waves travelled. It’s not accurate in discerning major EQ. The moment magnitude scale measures the amount of movement along a fault and the force required to make that movement. It also measures all of the seismic waves produced by an EQ.
The scales vary logarithmically. In terms of the amount of ground shaking, a difference of 1 varies by an exponent of 10. But in terms of energy released, it varies by powers of 30 (We round to 30. It’s actually 31.6. That means that for each increase in .2, the energy released is doubled)
Why do Earthquakes occur?
