Was There any lava flow at Mt St Helens?

User Avatar

Asked by Wiki User

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.

What is the height of Mount St. Helens?

User Avatar

Asked by Wiki User

The 1980 eruption reduced the volcano's height from 9,677 feet to 8,365 ft.Magma reached the surface of the volcano about October 11, 2004, resulting in the building of a new lava dome on the existing dome's south side. This new dome continued to grow throughout 2005 and into 2006. Several transient features were observed, such as the "whaleback," which comprised long shafts of solidified magma being extruded by the pressure of magma beneath. These features were fragile and broke down soon after they were formed. On July 2, 2005, the tip of the whaleback broke off, causing a rockfall that sent ash and dust several hundred meters into the air.vfah.efowiiiiiiiuvscv ktZAAh35555555555555555gow/h6.u7

Why did mount Saint Helens blow up?

User Avatar

Asked by Wiki User

It was triggered by an earthquake measuring 5.1 on the Richter scale, caused an eruption, reducing the elevation of the mountain's summit from 9,677 ft (2,950 m) to 8,365 ft (2,550 m) and replacing it with a 1 mile (1.6 km) wide horseshoe-shaped crater. The earthquake was caused by a sudden surge of magma from the Earth's mantle. The debris avalanche was up to 0.7 cubic miles (2.9 km3) in volume.

What is one way that volcanoes can be helpful?

Asked by Wiki User

The land around volcanoes are highly fertile due to the amount of minerals and nutrients that a volcano spews up which makes it a fairly good place for agriculture, although this tends to only happen in LEDC's where people are so poor they'll take the risks of being near a volcano.

When will mount saint helens erupt?

User Avatar

Asked by Wiki User

Predicting volcanic eruptions although part of the science of volcanology is the most difficult thing to successfully accomplish. The times between eruptions of volcanoes varies, and does not follow an exact pattern or time frame between eruptions. The only way that scientists have an idea of when a volcano will next erupt is when the volcano starts showing signs of unrest, and than it still depends heavily on what types of unrest the scientists are witnessing.
