While I was enjoying Christmas at my niece’s house, I noticed that my phone alerted me at 9:55 am (ET) that a magnitude 22 earthquake had hit in Montana at 10:50:39 (ET) on the 24th near Polson Montana.
The earthquake scale is logarithmic – a 6.0 is 10 times stronger than a 5.0 – a 7.0 is 100 times stronger than a 5.0. The quake that devastated Japan was around a 9.0. An actual 22 would basically mean the Earth just collided with Mars and exploded.
Five minutes later, it was corrected to the real 2.2, which is about the strength of a truck driving past your house.
