question: The 1980 eruption of Mount St. Helens is surpased by a volcano that was formed in 1912 located where?
answer: Katmai National Park and Preserve
context: Title: 1980 eruption of Mount St. Helens
  Passage: On May 18, 1980, a major volcanic eruption occurred at Mount St. Helens, a volcano located in Skamania County, in the state of Washington, United States.  The eruption (a VEI 5 event) was the only significant volcanic eruption to occur in the contiguous 48 U.S. states since the 1915 eruption of Lassen Peak in California.  However, it has often been declared as the most disastrous volcanic eruption in United States history.  The eruption was preceded by a two-month series of earthquakes and steam-venting episodes, caused by an injection of magma at shallow depth below the volcano that created a large bulge and a fracture system on the mountain's north slope.
  Title: Novarupta
  Passage: Novarupta (meaning "newly erupted" in Latin) is a volcano that was formed in 1912, located on the Alaska Peninsula in Katmai National Park and Preserve, about 290 mi southwest of Anchorage.  Formed during the largest volcanic eruption of the 20th century, Novarupta released 30 times the volume of magma of the 1980 eruption of Mount St. Helens.
  Title: Silver Lake, Washington
  Passage: Silver Lake is an unincorporated community in Cowlitz County, Washington.  Silver Lake is located 6 mi east of Castle Rock along Washington State Route 504, which is also known as the Spirit Lake Memorial Highway.  The Silver Lake community takes its name from the lake of the same name, which it lies on the northwest shore of.  The Silver Lake community is part of the Toutle Lake School District, a K-12 school district of about 600 students.  Silver Lake is near Mount St. Helens and the Mount St. Helens National Volcanic Monument, which lies at the end of the Spirit Lake Memorial Highway.  The eruption of Mount St. Helens on May 18, 1980 was the deadliest and most economically destructive volcanic event in the history of the United States.  The WDFW has planted Grass Carp in this lake, however it is illegal to fish for or retain grass carp.
