Hmm...well Hawaii builds out from lava flows some number of acres a year which I don't remember, and it varies a lot - but then sometimes it forms a shelf that breaks off and then you lose land area.

This is a different thing - the whole ground surface inflates like a balloon from magma below.

Appreciated. If Hawaii does have net growth, then the nation would be getting a little bit bigger each year (granted, a relatively tiny amount).
