So what's the problem? Well the problem is:

MAP 3.0 2010/06/11 05:06:14 41.683N 111.076W 0.1 9 km ( 6 mi) ENE of Randolph, UT

For those that are not sure what this means, the 3.0 is the magnitude and the 0.1 is the depth in km. The depth of a M3 earthquake near Yellowstone and it was just 100m from the surface!

Has anyone ever heard of an earthquake 100 metres from the surface? I know I have not and I look at the USGS and the AlertMap sites all the time. Links Above.

From the information given there have been 10 earthquakes in the past seven days that have been less than 1km (1000 metres) from the surface.

What is the cause:

Either someone is using considerable amounts of explosives in a seismically active area (Not smart), or this could be a magma chamber?

One thing, please change EVERY to EVER

Also what are you getting at? I understand you are saying this doesn't happen so what do you claim to think is the cause?

S&F. You made an excellent observation. I don't thinnk anybody has heard of an earthquake only 100 meters below the surface.
Nice find.

Thats interesting. I noticed there were several Earthquakes and now one thats 100meters from the surface...
Can anyone tell me if this is normal??

Edit: This is what I found from the Earthquake Facts on the USGS.gov website.

The deepest earthquakes typically occur at plate boundaries where the Earth”s crust is being subducted into the Earth’s mantle. These occur as deep as 750 km (400 miles) below the surface.

I am by far not an expert, but my hunch is the extremely shallow quakes are either caused by hydrothermal activity or surface interference at the reading station. Surface interference includes maintenance or wind/storms etc. Hydrothermal activity would include aquifers draining or heating up and expanding nearby rock.

A definitive answer from one of the geologists would be good. They can look at the actual seismograph and determine what the waves indicate. They can determine if it is water or hydrothermal, magma, surface blasting, drilling etc. Hopefully somebody will chime up soon.

Nice information. I had thought about some of those, but the magnitude of M3 made me think it had to be something more serious.

still awaiting email from USGC

you know m3 isnt all that massive plus as you must know there are constantly quake swarms near yellowstone. m3 could easily be manmade (dumbs anyone?)

edit: 3 on the richter scale EQ releases the equivalent of energy to about 1050lbs of TNT
