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 else can I help you with?
How much damage did mount st helens cause from its last eruption?
around 36 miles from it
How strong is Mt St Helens?
Mt St Helens erupted at 8:32 am PDT on May 18, 1980(a VEI 5 event). it erupted with 24 megatons of thermal energy. so yes, Mt St Helens was a very strong and large eruption. history repeats itself so it is safe to assume that it will happen again.
Why did the eruption of mount st helens cause so much destruction?
The eruption of Mount St. Helens in 1980 caused extensive destruction due to a combination of explosive volcanic activity and the resulting pyroclastic flows, ashfall, and mudflows (lahars). The eruption was preceded by a massive landslide that reduced the mountain's height and allowed for a lateral blast, which devastated areas up to 19 miles away. The release of ash clouds spread across several states, disrupting air travel and affecting air quality. Additionally, the eruption altered the landscape, leading to long-term ecological impacts in the surrounding region.
How much damage did mount Unzens worst eruption cause?
The worst eruption of Mount Unzen in 1792 caused over 15,000 deaths due to pyroclastic flows. It is considered one of the most deadly volcanic eruptions in Japan's history.
What type of eruption does mount vesuvius produce?
Mount Vesuvius is known for producing explosive eruptions. These eruptions are characterized by the sudden release of gas, ash, and volcanic rock, which can cause widespread destruction in the surrounding area.
How was the eruption of Mount Saint Helens?

Volcanic eruption types is the most violent?
Pelean
What is Mount Pelee's magnitude?
Mount Pelee's magnitude refers to the Volcanic Explosivity Index (VEI) of its 1902 eruption, which was estimated to be a 4. This VEI level indicates a significant explosive eruption that can cause widespread destruction and has a global impact.
What was the cause of the eruption of Mount Etna?
It's part of the volcanic arc above the Mediterranean floor plates subducting below the European continent.

The worst eruption of Mount Unzen in 1792 caused over 15,000 deaths due to pyroclastic flows. It is considered one of the most deadly volcanic eruptions in Japan's history.
Did the earthquake in Haiti cause a volcanic eruption?
No
What type of eruption does mount vesuvius produce?
Mount Vesuvius is known for producing explosive eruptions. These eruptions are characterized by the sudden release of gas, ash, and volcanic rock, which can cause widespread destruction in the surrounding area.
What type of lava flow was mount st Helens?
Dacite, a volcanic rock with about 65% silica. This amount of silica in dacite is a lot higher than the basalts of Hawaii which have less than 50% silica. The high silica content makes the magma "sticky" and can cause more pressure to build up. With so much pressure, eruptions from Mount St. Helens can be very violent like the famous 1980 eruption.
