Another Huge 6 Mag EQ in Turkey- VERY active right now

So I know the big quakes were posted earlier , however I decided to post this to make aware just how active things are still. I have been watching quakes pretty regularly over the past 3 years, and this is BY FAR the mos active ive seen this area in that time. Take a look at the last quakes and how big these aftershocks are.
quakes.globalincidentmap.com...
Something HUGE has to be brewing here, any body with alot of experience in this know anything?

The only thing I can add to this
is that the aftershocks are frequent
and large enough to cause
additional damage and injuries.
Perhaps aftershocks this large are
expected as this was a big quake.
I remember Japan had large
aftershocks after the main quake.

I feel bad for the people in the
area, they don't seem to be getting
much help with medics and equipment
to move debris.

I know aftershocks are normal but your right one this big! These poor people I wish good luck to them all. I mean that 6.0 aftershock was almost as big as the original quake

Well let me be the first to welcome you to the thread! Also let me be the first to say goodbye. (God forbid ya throw a little comment in lol)

After a large quake like today's mag 7.2 (USGS downgraded it from 7.3), it's not uncommon to get aftershocks, including a few up to one magnitude lower. While a mag 7.2 might not sound a lot bigger than a mag 6.0, it is actually a huge difference, both in terms of shaking and actual energy released.

This is because the quakes scales are logarithmic, not linear. Generally speaking, for each increase of 1 on the magnitude scale, the shaking increases by about ten times as much and the energy release by 32 times as much. (Actually it's the square root of 1,000, but it's close enough to 32.)

So, the difference between a mag 7.2 and a mag 6.0 is as follows:
A mag 7.2 is about 15.8 times stronger in terms of shaking than a 6.0, but the energy released is 63 times greater.

What this means is that it would take 63 mag 6.0 quakes to release the same energy as one mag 7.2 quake.

Here's a great page on USGS that explains it and also lets you try some comparisons yourself:
The USGS How Much Bigger page

Click on the "try it yourself" blue box at the top to do some comparisons. And don't worry, you only have to put in the magnitudes. It works out all the equations itself.

Short summary: even many dozens of mag 5 quakes won't get near the energy released by one mag 7 quake. There'll be quite a few quakes in the 4 to 5 range, but compared to the mag 7.2, their effect on the total energy released is quite small. It's very unlikely that there will be more than a couple more mag 6 quakes there (if any), and even they don't come close to the big mag 7.2 of today. However, all those smaller quakes are still bad news because they shake damaged buildings and make it more dangerous for people there.

Psychologically, they're also very bad.

Hope this helps.

Thanks Mike, you explained that very clearly. It is a fascinating field that interests me greatly and I appreciate reading posts from people who know what they are talking about.
Puts the Japanese quake in March into frightening perspective.
