Need help from ATSers in Quebec - Possible Touchdown

My friend just called me (we both are in NJ), his mother lives in Quebec and seems that she saw/heard something over there and wants to know what it was. My friend called me because he knows I'm a member here and consider ATS a good source for this kind of stuff.

Location : Quebec.
Day : 10/10/12
Time : Between midnight and 00:10
Description : Big boom sound followed by an earthquake.

Somebody else in that area had to feel that, hopefully an ATSer.

Uhm... not to be rude but Quebec is a huge province. I think you'd have to be a little more specific. Do you mean Quebec city?

Iris isn't showing up anything(it will only show mag 4.0 and above)

This is the seismic sensor for the Quebec area...

www.fdsn.org...

It is interesting to note the description of the activity in the area...

Site Description: SCHQ is located within the Eastern Background seismic zone, in which low-level but occasionally significant seismicity may occur. The region is seismically quiet in all directions from the station for greater than 300 km. The Lower St Lawrence seismic zone is about 450 km due south of SCHQ; the Boothia-Ungava seismic zone is approximately 600km to the northeast. Mine blasts from mines around Labrador City about 100 km to the south are recorded at SCHQ several times each week. The blasts take place around 15-16h. UT and normally range from 2 < MN < 3.

Thanks for the reply. Don't know the name of her town and I don't know Canada, but my friend told me she is just half hour from Montreal (I hope that helps). She said all the neighbours felt it too.

Thanks for that input, but remember there was a "boom" previous to the quake.

Thanks for that input, but remember there was a "boom" previous to the quake.

If you had of read my post you might have noticed the the reference to mining and explosives.

You might also have noticed that the area in question is a seismically inactive region.

Which leaves few possible causes...

1) Asteroid
2) Mining
3) Fire
4) Sonic boom from jet.

1) Probably would have been in the news
2) Unlikely unless the person who heard it was near mines
3) Very likely, though an explosion caused by a fire that was large enough to shake the ground would be on the news
4)Very likely, though unverifiable.

1, 2, & 3 are verifiable.....Occam's Razor can be applied here to nut-out which one was the cause.

What makes this a "Possible Touch Down?"

Peace

We had a 4.5 earthquake recently near Montreal
but didnt feel anything

i live 30 min from Montreal
its always very calm in the region i live

the Touch Down is Stephanie Trudeau the female BAD cop
thousand of people are in the streets because of her bad attitude
and some are even asking for her execution .. its getting out of control
cops car are now parked 24/24 outside her house to protect her

the SPVM are getting hammered because of her
people are really fed up of the Montreal cops always using excessive force
especially this one below



Listen to her professionalism always swearing and insulting

I'm an hour and a half from Montreal , there was a 4.5 reported in St.hyacinthe which is 37 kilometers from Montreal, Quebec . It was just after midnight , we didn't feel it where we are

The sound they heard first.

Haven't heard or felt anything.

I just know that the earthquake was reported. I haven't heard anything from anyone about a possible touchdown.

Not much help, sorry...

Thanks for those links, so the quake is confirmed. Not sure about what provoked it, I noticed there is no information about the depth of the epicenter.

“The epicentre is 21 kilometres west-northwest of Saint Hyacinthe and that’s about 37 kilometres from Montreal,” Ms. Bent said in an interview from Ottawa.

Wednesday October 10, 2012
Local Time: 00:19:28 EDT
Magnitude: 4.5 MN
Latitude: 45.69 North
Longitude: 73.2 West
UT Date and Time: 2012/10/10 04:19:28 UT

The missing info is important to determinate the cause.

Small earthquakes are fairly common in this neck of the woods !

Yes, I'm aware of that, what I wonder now is described in my previous post.
