Volcano

So when I was taking my kids to school I went down the drive way in my trolley and then I could see this steam in the ocean. I thought it was a whale breathing but then black stuff came out so then I want to see what happened at the end the BOOM!!. Tephra and loads of ash came shooting at into the sky and then black smoke came out. Next and boom blocks came out and then black smoke came rushing down also the waves they rushed and fast as possible and I knew it was to late to run. after that smoke went away likely my friend put a gas mask on me. The thing that I saw was anther land and that happen by a hotspot how the magma because the lava comes out and it cools down by the water and the how it formed a new island.
