Chain reaction happened when Thor's Lightning met the reactor core.But the whole initial disintegration of the top of the landscape was all Thor.
And I disagree with what you said. Energy was protruding from the landmass right before Thor struck. Thor struck the generator to send the energy through.
The very fact that IM overloaded the engines prior and told Thor "On my mark" and Thor struck the generator makes it a shared and quantifiable feat.
