I don't think they are aftershocks. therefore they are to close to each other with the magnitudes. if a earthquake happens around 5.1 magnitude, then there must be afterhocks around 2.5 and not 4,5.

Or a volcano is going to erupt, or Afrika is splitting apart, and I think the last part.

a volcano is going to erupt,

we jump to any conclusions as they have a 90% fail rate : Could be anything . Whoever can, check the magnetic fields close by and don't forget there's a lot of firepower concetrated in the area. Let's wait and see. Unusual area for such high magnitude quakes though.

They are now at 14 quakes/aftershocks with two 5.7s.

what's in the sky overhead? Is there a satelite that could be causing this?

while we are constantly being sandwiched between the bottom of the ocean and the atmosphere above us, not to mention constantly stalked by Space Forces far more powerfull than us, we have idiots worrying about banckruptcies, fiscal emergencies , debts and who among us is going to dominate the planet. Idiocy has gone ballistic on this planet. Has anyone of the earthlings realized that there isn't any place on this planet that is totally
and absolutely safe forever ? That it is a matter of survival and international cooperation and not money any more ? That as gradually we 'll have to leave this planet, Space is far more dangerous ? That we virtually know nothing and that we have to keep on learning ? That nobody among us is going to live forever ? That if we continue operating the way we do eventually we 'll end up accomplishing the impossible and make the planet flat ? Oh, man I don't know why I even bother...
