likeMount St. Helens' 1980 eruption) are typically triggered when molten magma burbles up from deep within the Earth into the volcano's magma chamber,explains Alexandra Witze forNature. This causes an increase in pressure, and when the pressure climbs high enough, the volcano erupts. ...
Volcanic hazards occur when a volcano erupts, starting dangerous geologic processes that can threaten life, destroy property, and flatten infrastructure. Learn about volcanic hazards such as landslides, lahars, and tsunamis, and explore how the loss of life from them may be preventable through early...
How do airlines decide it's not safe to fly when a volcano erupts? The decision is made by each airline's operational staff. Each airline's operational team would be looking at the situation in real time today and making the decision based on theirrisk assessment. Every airline has a proc...
Why do earthquakes occur before a volcano erupts? How will erosion and deposition affect a mountain range? Why is Australia geologically stable? What are landslides in mountain orogeny? How has erosion impacted the Rocky Mountains? Why is Earth geologically active?
Every time a volcano erupts, we're reminded that we're merely passengers on a floating crust, which drifts around on a liquid core of molten rock and metals many miles below. But this liquid core is essential to life. Because of its metallic elements being in content movement, the inner ...
Magmatic underplating beneath the oceanic Moho has been proposed to accompany basaltic melt that erupts at the seafloor and (eventually) atop a subaerial volcano. An alternate hypothesis is "metasomatic underplating" whereby crustal fractures developed during magma ascent allow seawater to infiltrate and ...
The eruption started on March 19 when a new fissure 500 to 700 meters (1,600 to 2,300 feet) long opened in a valley on the island's Reykjanes peninsula. It happened in an area called Geldingadalir near the volcano Fagradalsfjall. There, molten rock flowed up through Earth's crust....
Why does the lava that flows slowly down the mountain cause far more damage than the boiling rock that erupts from the volcano? A. Because it buries everything in its path. B. Because most people live near the top of Mount Kilauea. C. Because the lava is in a higher temperature。 D....
Translated into English as “canyon dweller” or “dweller of the gorge”, Gljúfrabúi waterfall is a true beauty hidden away below steep cliffs. The waterfall cascades down into a little cave with light pouring in from above — a truly beautiful sight that is worth veering off the beaten...
