When Mt. st Helen's erupted it had a pyroclastic flow because all of its magma was high in silica so it cloged the pipe when the magma was trying to leave so when it finally exploded it came down as a pyroclastic flow

Yes. Mount St. Helens produced many pyroclastic flows.
Does mt st helens have pyroclastic flow?
No. It has a crater, which is not quite the same as a caldera.
Was there a pyroclastic flow in mount Pinatubo in 1991?
Yes. There were many pyroclastic flows from the 1991 eruptions of Mount Pinatubo.
How did david johnston and Harry Truman die mount st helens?
David Johnston was melted by the gasses of Mt.st.Helens. Harry Truman was killed by a pyroclastic flow, burying him and his lodge under 150 feet of volcanic debris. Overall, they were both killed by the pyroclastic flows.
Does Mount Etna create pyroclastic flow?
Yes, in 1999,2006, and 2012

What type of flow does mt st helens have?
Mount St. Helens has produced lava flows in the past. However, the famous eruption in 1980 produced something much more dangerous: pyroclastic flows. These are avalanche-like currents of hot ash, rock, and gas that race out of a volcano. The initial pyroclastic flow from the lateral blast may have briefly been supersonic.
Where has a pyroclastic flow killed people before?
There have been a number of cases. Pyroclastic flows killed people in Herculaneum in the 79 AD eruption of Mount Vesuvius, in Ketimbang and on the Island of Sebesi in the 1883 eruption of Krakatoa, in St Pierre in the 1902 eruption of Mount Pelee, in the state of Washington in the 1980 eruption of Mount St Helens, and in Japan during the 1991 eruption of Mount Unzen.
What type of lava flow does mount meakan have?
it has pyroclastic flow and has small eruptions of ash.

What type of lava flow did mt st helens have?
The 1980 eruption of Mount St. Helens did not produce lava flows. It was a plinian eruption that produced aolumn of ash and pyroclastic flows. Pyroclastic flows are avalanche-like masses of hot ash, rock, and gas that rase away from an erupting volcano at speeds that can reachinto the hundreds of miles per hour.
Was There any lava flow at Mt St Helens?
Yes, there was a significant lava flow during the eruption of Mount St. Helens in 1980. The eruption caused the collapse of the volcano's summit, leading to a massive explosion and the release of a pyroclastic flow. This flow melted the ice and snow on the volcano, mixing with ash and rock fragments to create a fast-moving lava flow known as a lahar.
How far did the lava flow in the mount st helens eruption?
The 1980 eruption of Mount St. Helens did not produce lava flows. It was an explosive eruption that prudiced an ash plume and pyroclastic flows. Pyroclastic flows are avalanche-like masses of superheated ash, rock, and gas. Pyroclastic flows from the initial lateral plast reached as far as 19 miles. Ash blown high into the atmosphere was carried by the wind for thousands of miles.
