No, it can be something as lowly as a mag 6 earthquake as we have just seen demonstrated.
Normally a deep earthquake of around 6.5 will ring all the siesmos in the world like a bell. As an example the deep (600+km) Brazilian earthquake
earlier this year. This type of earthquake will do little or no damage at all but will be seen on seismos everywhere.
There has just been a 6.1 around where the 5.8 that caused this thread happened. It will be interesting to see if that too appears on all the
siesmos.I do think that one yesterday was a double.
Sometimes it is difficult to get ones head round earthquake magnitudes, but take two extremes.
- 3.0 which few people will even notice and will
do no damage (normally)
- 9.5 The most powerful earthquake the world has experienced.
The difference in strength between these two quakes is not 6.5 times stronger, but is..................
5,623,413,251.9
Yes five billion six hundred and twenty three million, four hundred and thirteen thousand two hundred and fifty one point nine times stronger!
That takes some getting your head round. It is the equivalent of 2.67 gigatons of TNT
