I find volcanos fascinating. Truly a force of nature, with all the hot lava and ash and gases. The recent eruptions in Hawaii were both terrifying and strangely beautiful (if not destructive, of course ;-( )
I heard that some islands have active volcanos to this day! I heard they canerupt but probably ownr
And they are *ancient*. Mauna Loa has been erupting for at least 700,00 years!!!
