Who listed below died as a result of the eruption of Mount St. Helens?

Harry R. Truman (October 30, 1896 – May 18, 1980) was a resident of the U.S. state of Washington who lived near Mount St. Helens, an active volcano. He was the owner and caretaker of Mount St. Helens Lodge at Spirit Lake near the foot of the mountain, and he came to fame as a folk hero in the months preceding the volcano's 1980 eruption after he refused to leave his home despite evacuation orders.

As the likelihood of eruption increased, state officials tried to evacuate the area with the exception of a few scientists and security officials. On May 17, they attempted one final time to persuade Truman to leave, to no avail. The volcano erupted the next morning, and its entire northern flank collapsed (see photo) Truman was alone at his lodge with his 16 cats and is presumed to have died in the eruption on May 18. It is likely that he died of heat shock in less than a second, too quickly to register pain, before his body was vaporized. The largest landslide in recorded history and a pyroclastic flow traveling atop the landslide engulfed the Spirit Lake area almost simultaneously, destroying the lake and burying the site of his lodge under 150 feet (46 m) of volcanic landslide debris. Authorities never found Truman's remains. Truman's cats are presumed to have died with him; he considered them family and mentioned them in almost all public statements.
