What kind of lava does mount st Helens produce?
The material produced by the eruptions of Mount St. Helens have varied over time, but the eruptions of recent decades, including the 1980 eruption, have involved dacite magma, whish is of intermediate-felsic composition. The famous 1980 eruption produced ash and pumice rather than lava.
Is Mount St. Helens the biggest volcano on earth?
mount saint helens formed a massive buldge because the magma was blocked of frm the top of the volcano so it turned to the side and formed the big bulge the lava still couldn't get out so was forming the bulge to make more pressure on the skin that was blocking it from getting out in the end there was an earth quake measuring 5.1 on the Richter scale the north face of the volcano collapsed into a massive rock avalange the bulge was going down with it. nearly 230 square miles was blown down or buried beneath volcanic deposits.

When the erruption of Mt. Saint Helens happened people reported seeing ash clouds as far as California going west and east as far as Wisconsin and south to Utah, Colorado, and Wyoming.

What is the current status of the mount st helens?
Mount St. Helen lost nearly 2/3 of its size during the catastrophic eruption. It is smaller in size now and mostly barren, some small undergrowth is reemerging but volcanic ash is very suffocating to new growth for many years. Repeated rain, erosion and mixing with soil will turn in into good mulch eventually, but for the most part, areas of St. Helen's resembles a moon-like surface.

What was the cause of Mount St Helens volcanic eruption?
Mt. Rainier is part of the Cascade Volcanic Arc, which extends from Northern California north into Canada. These types of volcanoes are most known for their explosive eruption types. Mt. Rainier is no exception to this, it has produced major explosive eruptions in the past and will in the future. This type of eruption is generated through having a highly viscous supply of magma that does not allow for the readily release of volcanic gasses. The pressure builds and once the onset of eruption occurs, explosive decompression of the magma chamber can ensue.
it is an explosive volcano (erupts ash, rock, debris, and the like) and one of the most dangerous in the world
The mountain itself was put on the decade list for the most potential threat to people and property within a decade, however there have been no signs of the mountain re-awakening in the near future. CVO's website does do weekly updates every friday on the current conditions of the volcanoes in this volcanic arc.
Mt. Rainier can erupt explosively like any other stratovolcano, however it can also erupt passively. It simply depends on what is going on inside the volcano that is triggering the eruption and how much energy is stored in the magma chamber. As a side note Rainier doesnt necessarily need to erupt to cause significant damage. The mountain has the highest concentration of glaciers and a simple rise of summit temperature could be enough to trigger a lahar.

What is the date and time of the eruption of mount st helens?
Mount St. Helens, located in southwestern Washington state in the Cascade mountain range, erupted on May 18, 1980. Sixty-one people died as a result of the eruption. This was the first known volcanic eruption in the 48 contiguous United States (excluding Alaska and Hawaii) to claim a human life. Mount St. Helens is classified as a composite volcano (a steep-sided, often symmetrical cone constructed of alternating layers of lava flows, ash, and other volcanic debris). Composite volcanoes tend to erupt explosively.
