yes
The word 'causalities' in this case refers to the number of human deaths caused by the earthquake.
yes and no
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!

yes
I don't know what you mean with "larer", but a kilogram is more than a gram. 1 kg = 1000 grams.
A small earthquake

Nope. Don't believe it. Just because there was an earthquake in Japan doesn't mean we'll ALL die.
I think you mean catastrophic, which means causing a great deal of damage. The earthquake was catastrophic for the small village.
It means that the earthquake is large and powerful.
go to the doctor
A dog groaning could mean anyhting. It could indicate that they have some sort of pain in their body, or that something like an earthquake could be coming.
