Past Eruptions
Kasatochi- Gulf of Alaska (North American Plate)
When the Kasatochi erupted, the volcanic acid and ashes fertilized the ocean that was followed by a huge bloom of a special food source, phytoplankton called diatoms. This big spurt allowed a rich source of food to the salmon brought about 34 million salmon into BC’s Fraser River increasing the selling of salmon and providing easy and great money making jobs for fishermen.
Cascade Mountain Range- Western North America (North American Plate)
In the past few thousands of years, volcanoes of the Cascade Mountain Range go across western U.S. all the way from California to British Columbia. These volcanoes have created over 100 volcanic eruptions, with most of them being explosive. When Cascade volcanoes erupt they send high-speed avalanches of hot ash and rocks, lava flows, and landslides that can destroy areas 10 or more miles away. Volcanic mud and debris can flood streams as fast as 20 to 40 miles per hour and can roam from more than 50 miles downstream. The Cascade Mountain Range is part of the Pacific Ring of Fire, and includes Mount St. Helens, Mount Baker, and many others.
Mount Rainier- Washington–near Seattle (North American Plate)
Mount Rainier is an active stratovolcano volcano in Washington located on the North American Plate. Scientists say to watch out for “The Ring of Fire” (Mount Rainier) because it is one of the most dangerous volcanoes in the US, and could affect British Columbians if it is to erupt again.
Mount Baker- Washington (North American Plate)
Mount Baker, observable from where we live (Golden Ears), erupted over 6600 years ago, and hasn’t shown any sort of volcanic activity for another 1000 years. Long periods of time between volcanic eruptions can make people forget about the hazards/dangers they pose. The only way to learn about these past events are to look into the records made by the natives of that region.

Recent Eruptions
Recent eruptions on the NAP are the eruptions of the Eyjafjallajokull (Iceland– 2010), and Mount St. Helens (USA– 1980). These eruptions caused the planet to cool for a couple years and made air travel difficult because of the floating ash.
Volcanoes at Yellowstone and Taupo are volcanoes that could do massive damage to the world economy and have many effects on the environment around the world (weather, landforms…etc.), possibly changing the very way we live today.
It's a good thing that big scale eruptions only happen once every few thousand years, with some small eruptions (cinder cone volcanoes…etc.) every once in a while.
