it was a brief casual conversation amongst a few of us, his main point as i understood it being that the EQ was generally the result of the weight of the island on the crust rather than an indication of some sudden subterranean intrusion of magma. though i could see how it often might not be the case of one or the other, but sometimes rather both - a settling triggered by magma intrusion.
was his assessment correct? i don't know. sounds reasonable though.
my impression was he was using the term tectonic in a broader sense in casual, less technical conversation...

volcano tectonic earthquake... that's new to me, also. the term almost sounds like an oxymoron on the surface of it.
