Aftershocks Are Still Earthquakes! (Wikipedia) Explanation follows.

An aftershock is a smaller earthquake that occurs after a previous large earthquake, in the same area of the main shock. If an aftershock is larger than the main shock, the aftershock is redesignated as the main shock and the original main shock is redesignated as a foreshock. Aftershocks are formed as the crust around the displaced fault plane adjusts to the effects of the main shock.

Omori's Law The rate of aftershocks with time follows Omori's law.[1] Omori's law, or more correctly the modified Omori's law, is an empirical relation for the temporal decay of aftershock rates. In 1894, Fusakichi Omori published his work on the aftershocks of earthquakes, in which he stated that aftershock frequency decreases by roughly the reciprocal of time after the main shock. n(t) = \frac [K] [c+t] where: n(t) is the rate of earthquakes measured in a certain time t after the main shock, K is the amplitude, and c is the "time offset" parameter. The modified version of Omori's law, now commonly used, was proposed by Utsu in 1961.[2][3] n(t) = \frac [k] [(c+t)^p] where p modifies the decay rate and typically falls in the range 0.7–1.5. According to these equations, the rate of aftershocks decreases quickly with time. The rate of aftershocks is proportional to the inverse of time since the mainshock and this relationship can be used to estimate the probability of future aftershock occurrence.[4] Thus whatever the probability of an aftershock are on the first day, the second day will have 1/2 the probability of the first day and the tenth day will have approximately 1/10 the probability of the first day (when p is equal to 1). These patterns describe only the statistical behavior of aftershocks; the actual times, numbers and locations of the aftershocks are stochastic, while tending to follow these patterns. As this is an empirical law, values of the parameters are obtained by fitting to data after a mainshock has occurred, and they imply no specific physical mechanism in any given case.

I think what is happening in Canada is unusual.

Why, because they had an Earthquake and some Aftershocks which generated a Tsunami which may aswell of not been a Tsunami?

It made me angry when watching the events of the Fukushima crisis play out. Quakes verging on the 7's and 8's were considered aftershocks, even when weeks had passed.

Bloody stupid!

There NO earthquakes with a magnitude 8+ after the main one and there were three magnitude 7+ aftershocks.
Why does it make you angry what they were called ? what would it change if they weren't considered aftershocks ?

seems unusual to me too.

i see no fear mongering in a discussion about how unusual the quakes in canada are.

Tried to line these up, hardly matters. This is not normal behavior for any a earthquake/aftershocks/swarms,
whatever you call them.

Wow. I hope these people are doing okay? Just in the time I was writing this post they have had more. And the area north of that in Alaska seems to be doing some shaking. Last month it was California, but those swarms dont't seem to have the same intensity as this one. I have not seen this activity in Canada for the time I have been following patterns. Maybe they have had this before. i know that area has had earthquakes, but like this, in a 12-24 hour time frame?

No fear mongering spam here.

I know it can be frustrating at times. I have something I say to my self often when dealing with disruptive souls. I am sure you have heard it in some form of semantics before. Here it is in my own translation:

Give me the Compassion I Need To Accept The Things I Can Not Change (people, places and things),
The Ability I Need To Change The Things About Myself That I Want To Change,
The Capacity To Accept The Differences.

Try to apply this to any situation and find a way to set a time aside for yourself each day to reflect and breath at peace. Meditation/Prayer, whatever works for you. Take care. Much love and understanding. Ascension211

LOL, this is the definition of fear mongering, if I looked up fear mongering in the dictionary, I'll probably see your thread there. Aftershocks are normal, here is a link to a 7.6 EQ in Costa Rica, similar magnitude and there were 1,650 aftershocks in the next following 5 days.

Earthquakes happen and there are aftershocks simple as that, bigger earthquakes means more aftershocks

Just pointing out this is not normal. Why does it have to be " fear mongering"? Did I mention nubiru? 2012? run for your lives, I did what I am supposed to do and give my opinion. Bring facts, which I did and here is another one for you! And sent love to those people in that area.

Fear mongering (or scaremongering or scare tactics) is the use of fear to influence the opinions and actions of others towards some specific end. The feared object or subject is sometimes exaggerated, and the pattern of fear mongering is usually one of repetition, in order to continuously reinforce the intended effects of this tactic, sometimes in the form of a vicious circle.

PS. Read my signature!

My use of this phrase was in response to a post that has been censored.

Oh come on, people. The Queen Charlotte fault is no stranger to earthquakes, it just doesn't see them as frequently as elsewhere. It was bound to happen at some point, history shows biggies have happened before. Would you feel more at ease if it had sent you an invitation to join it personally at a scheduled time? And good lord, stop with the aftershock wondering. It's supposed to do that, it's a huge, huge slab of earth that was disturbed, do you expect it to just shake a little and be totally done with? That's miles upon miles of geological layers. Use logic, goddang.

Such a cavalier attitude about the people that are there. 61 quakes in less than 30 hours. That seems very high to me. Thanks for informing me.

Seems very high?? Clearly you have not researched the aftershocks of other major quakes. Go check out your neighbor countries' aftershock counts, I'm sure Chile, for example, would be easy research with all the major ones under their belt.

reply to post by Nyiah


There is no argument here. You are wrong if you think this is not unusual. Just go do the research yourself. I have.
