The San Francisco volcanic field is a vast area covering more than 10,000 km22 containing cinder cones, lava fields, lava domes and the majestic (extinct) San Francisco Peaks, the highest of all mountains in Arizona, rising 5,000 feet above the surrounding plateau. Some believe a Yellowstone terrorist attack causing the supervolcano to erupt would be far worse than an EMP. Use the term “super volcano… Structure of super volcanos >Large depressions called calderas >No usual cone like structure. This means the volume of deposits for that eruption is greater than 1,000 cubic kilometers (240 cubic miles). That said, not all volcanic eruptions are dangerous. Yellowstone’s supervolcano is essentially a giant, lid-topped cauldron, and it’s so vast that it can only truly be seen from low-Earth orbit. Lava last flowed from the volcano 70,000 years ago.
