very shallow. Watch ATS speculate on this

Damn, it seems like a significant quake is poppin' off every hour or so.

Strange days indeed.

Had to change title and update first post because two occured in Utah AT THE SAME TIME!!!!!

I mentioned it in my oregon and canada quake threads. Something is crazy and i have a wierd feeling madrid is coming close to going too, if all this ground underneath is adjusting and moving, well then what says its not gona happen.

Automated systems do that.
Early reports are mostly generated by software, thats what you're seeing now.

It is VERY common to see such "multiple" reports early on, before the data gets reviewed by humans.

I don't know if it is truly so strange to have such a rapid series of earthquakes all over the place, or if we're just more keen to talk about them now than in the past.

Maybe we're about to finally be enlightened by the mole-people.

one or two, wonder what the mag will be closer to, if/when they update it to one.
i only saw 4.1

yeah regardless, why so shallow. and in Utah?

who felt it??



too many sizeable quakes for one 24hr period! and its not even over yet..

one in Georgia, too?

I will keep an eye on that, thank you for the info Alfa

Here is the map with the location and a link to more info. And they are very shallow as well. All this activity is going to cause alot of worry and speculation. We can only wait and see what happens in the next 24 hours.

North atlantic off coast of Nova Scotia

Southern mid Atlantic ridge also

Wonder if there is something going on with the sun or because we just got over a full moon. My friend in Kentucky has got a freeze warning tonight...
And like no one is telling us anything? And I'm not a conspiracy guy, nor do I believe in flying saucers, global warming or many of the fashionable things to believe in...

The 4.8 was just downgraded, but still showing two at the same time:

if our lunar activity has a significant impact on us.

and if our solar activity has a huge impact on us,

then just fathom how much our galactic activity does!

For those keeping score like me, here are the last 24 hours:

I live in SoCal and have literally slept through 4.0 - 4.8 quakes.

They're not that big of a deal. I suppose someone who has never felt a quake would panic, but that magnitude is really just a hiccup.

I'm in Daytona and in the 70's when I was a kid we had a small one that my Dad felt but I slept though it.

Better source with more info.

Depth is still at zero so the real info is not in yet.

The Intermountain seismic belt (ISB) is a prominent north-south-trending zone of recorded seismicity in the Intermountain West. A modern catalog of instrumentally located earthquakes in Utah begins in mid-1962, and historical earthquake records date back to the 1850s. The ISB in southern Utah is characterized by scattered seismicity with locally dense clusters of small- to moderate-sized earthquakes. The largest earthquake in the ISB in southern Utah was a M6.5 earthquake in 1901 in Richfield. A group of three M5 and 6 earthquakes occurred in Elsinore in the Sevier Valley in 1921. To the south in southwestern Utah, a damaging earthquake (M5.9) occurred in 1992 near St. George. Earthquake swarms (clusters of earthquakes with no outstanding main shocks) of maximum magnitude 3 to 4 are common in the area.

Because moderate and large earthquakes are likely, expected levels of strong ground shaking are relatively high. Ground shaking from a M5 earthquake can cause significant damage at distances up to 10 km (6 miles), and a M7 at distances up to 50 km (30 miles) and more. Geologic site conditions such as deep sediment-filled basins may locally amplify and prolong ground shaking.

Historical Seismicity



For context on today -
Average numbers per year.

8 and higher 1
7 - 7.9 15
6 - 6.9 134
5 - 5.9 1319
4 - 4.9 13,000
(estimated)
3 - 3.9 130,000
(estimated)
2 - 2.9 1,300,000
(estimated)

Factor in the lesser magnitudes and if memory serves it's one every 6 seconds.

See my post above this one. Nothing strange at all going on. It's just that the information is so easy to get now. Remember averages cover long time spans and not every year is the same. However this year looks quite normal.

Anyone else feel like the biggest EQ in recorded history is about to happen?


hmmm,
Maybe it's just me.
