Just heard on the Radio that there was a little earthquake here in the area of Wiener Neustadt, Austria, tonight at 2:37 am (cest). I guess nearly nobody felt it, because of it's very low magnitude of 2.6 on the Richter scale. Don't know what it was on the Mercalli intensity - would guess a II.
As I surf through the web I just saw that ther was one on Monday at 5:07 am (cest) too. That one was even an 3.5 and woke some people up. I didn't notice it anyway.
In our area earthquake aren't to seldom but they are most times not even really perceptible. The average rate for perceptible ones in Austria is 16 per year.
I am very gratefull for that low rate!
Richter and Mercalli Earthquake Scale
- The Richter scale was created in 1935 by the American seismologist Charles F. Richter. It measures how much the ground shakes 60 miles from the earthquakes epicenter. Richter magnitudes increase logarithmically, meaning the energy increases 10 times for each magnitude number.
- Mercalli intensity is based upon observations of the resulting damage and not actually measured on instruments. Invented by Italian seismologist Giuseppe Mercalli.
