Canada may seem stable but there's a reason Mt Tremblent is called Mt Tremblent. We get a few small earthquakes most years it seems but nothing like Hawaii. I've been on the slopes of a volcano while it was erupting and it's an amazing display of power. It was quite safe, it was Arenal in Costa Rica but you could feel and hear the rumbling. Unfortunately I didn't see any lava flow as the thing was in cloud all the time. I also made plans to go and see a rising lava lake in a volcano in Nicaragua that had just become active, Masaya. It was one of only three in the world with a lava lake that could be viewed easily. I couldn't go in the end as wife wasn't feeling well but she promised me we would go back. It will have to be soon though as these things can go as quickly as they appear. There were rules at Masaya, they only let so many cars up at a time, you had to park nose out for a quick getaway and you were only allowed 5 minutes at the crater rim because of noxious gases. While I was in Nicaragua a volcanologist fell into the crater and was rescued after cooking for a while...he was alive but a bit dehydrated.
