One of my volcanoes is Mt. St. Helens. It is in Washington state. It stands up 8,364 feet (9,677 feet before May 18, 1980). The 1980 eruptions of Mount St. Helens in southwestern Washington marked the re-awakening of a kinda young  volcano. (40,000 years)  that had been dormant since 1857.

    Mount St. Helens remains a potentially active and dangerous volcano, even though since the 1980's it has been quiescent. In the last 515 years, it is known to have produced 4 major explosive eruptions (each with at least 1 cubic kilometer of eruption deposits) and dozens of lesser eruptions. Two of the major eruptions were separated by only 2 years.

    My other volcano is Mt. Vesuvies. Today two million people live in the close by to Mount Vesuvius. This mountain has erupted more than 50 times since 79 A.D., when it covered Pompeii and its sister city, Herculaneum. After Pompeii was buried and lost to history, the volcano continued to erupt every 100 years until about 1037 A.D., when it entered a 600-year period of quiescence. In 1631, the volcano killed an additional 4000 unsuspected people. It was during the restoration after this eruption that workers discovered the ruins of Pompeii, buried and forgotten for nearly 1600 years.
