A main shock is the largest earthquake in a sequence.
infrasound
They are called aftershocks, tremors that follow the main shaking.
Well, from what I understand, there's the main Earth Quake, and then an After Shock, which is a smaller Earth quake usually followed up from the main one. I'm not sure if this is what you mean, but I hope it helps!
a after shock is what happens after a earthquake
A lightning shock is bigger than a carpet shock because a lightning shock has bigger and more severe energy.
A fore shock is a shock before the earthquake(main shock) and can be quite danerous. An after shock is a shock after an earthquake that are usually way more dangerous then foreshocks.
I'm assuming you know how earthquakes occur and all an aftershock is a smaller earthquake after a larger one. If the "aftershock" is larger than the main shock it is reclassified as the main shock and the previous "main shock" becomes a foreshock.
The shock cord keeps the nose cone attached to the main tube.
A small earthquake that follows the main earthquake.

You have the cartilages in the joints, which act as mechanical shock absorbers. But then you have other functional shock absorbers. You have arches in the foot, which act as shock absorbers. Then when you jump down, you have that spring like movement of the legs. That act as a shock absorbers.
It is a shock wave +++ Well, yes, an earthquake is a series of shock-waves, but I'm puzzled by what the question really means. The main tremor is often followed by smaller "after-shocks".

It's a smaller (or sometimes larger) earthquake after the main earthquake
The main risk from using a dog shock collar, is that the collar itself can result in poorly timed intense electric shocks in the wrong hands and can therefore instill fear and anxiety in the dog.
Foreshock is what you call one of the little earthquakes that come before the big earthquake or main shock. The main shock may be followed by a little earthquake that's called the aftershock.
