Yes. Mount St. Helens produced many pyroclastic flows.
No. It has a crater, which is not quite the same as a caldera.
Mt. St. Helens did not have lava flow during its 1980 eruption. Instead, it underwent a catastrophic lateral blast that expelled hot ash, steam, and debris. The eruption resulted in a massive eruption column and pyroclastic flows.
No, the eruption of Mount St. Helens in 1980 was primarily explosive, generating pyroclastic flows and ash clouds. There was some minor lava extrusion, but the majority of the volcanic material consisted of ash, pumice, and other debris.
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
Mt. St. Helens is known for its explosive eruption in 1980, characterized by ash clouds, pyroclastic flows, and lateral blasts. It is considered one of the most significant volcanic events in U.S. history.

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.

At Mt. St. Helens.

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.

Mt. St. Helens is known for its explosive eruption in 1980, characterized by ash clouds, pyroclastic flows, and lateral blasts. It is considered one of the most significant volcanic events in U.S. history.
Mount St. Helens is a stratovolcano, also known as a composite volcano. This type of volcano is characterized by its steep slopes and explosive eruptions due to a mixture of lava flows and pyroclastic material.
Yes, of course Krakatoa has a pyroclastic flow. Every volcano has an pyroclastic flow, which can travel up to at huge speeds. Krakatoa's pyroclastic flow raced an amazing 200 mph over 20 miles of open sea. Yes Krakatoa has pyroclastic flows but not all volcanoes produce pyroclastic flows, only Mt. St. Helens type volcanoes usually composed of andesite. Kilauea for example does not produce pyroclastic flows because it is composed of basalt, the lava flows out easily.
Mt St Helens first erupted on May 18, 1980
