Volcanoes with Liz

I thoroughly enjoyed the vignettes on volcanoes. But I live around extinct volcanoes, my home was on the lip of Aliamanu Crater off of Salt Lake Blvd. I left there after my growing fear of those very massive volcanoes, Diamond Head, Koko Head. Now, my fear strarted after an earthquake some time in the early 80's, it
woke me at 4AM.
Now the earthquakes are again coming close to us here in Wisconsin. How many faults are in and around the Great Lakes area? And what are the chances that there could be a massive change in magnetism and shift us all around with the ever increasing solar flair. Could magnetism have that much of an effect on our life styles? Thank you, hope I let you know how much you small studies were enjoyed.

Great

Great, vibrant presentation! You just need to fix the drops in volume when you go to a picture to be perfect.
