How many times more powerful was vesuvius than St Helen?
To determine how many times more powerful Mount Vesuvius was compared to Mount St. Helens, we can consider their explosive volcanic eruptions and their respective Volcanic Explosivity Index (VEI) ratings. The VEI is a logarithmic scale that measures the explosiveness and power of volcanic eruptions, ranging from 0 to 8.
First, we need to find the VEI ratings for each volcanic eruption. Mount Vesuvius is famously known for its eruption in 79 AD, which had a VEI rating of 5. On the other hand, Mount St. Helens had a highly significant eruption on May 18, 1980, with a VEI rating of 5 as well.
Since both Mount Vesuvius and Mount St. Helens had the same VEI rating, it indicates that their eruptions were of relatively similar magnitude in terms of explosiveness and power. Therefore, we can say that Mount Vesuvius was not significantly more powerful than Mount St. Helens.
In summary, based on their VEI ratings, Mount Vesuvius and Mount St. Helens had similar levels of power during their respective eruptions.
