What are two ways that a volcanic eruption can benefit people?
Two ways that volcanic eruption can benefit people include the creation of land mass and of energy. Volcanic steam and heat can be used to produce energy.

What was the Richter scale for the Kobe earthquake?
It did not have a Richter scale rating. The Richter scale is used to rate earthquakes, not volcanic eruptions. Volcanic eruptions are rated on the Volcanic Explosivity Index. The 1991 eruption of Mount Pinatubo was a VEI 6, described as a colossal eruption.
How does a GPS predict a volcanic eruption?
High-precision GPS can be used to detect shifts in the ground on and near a volcano. This can be used to infer the underground movement of magma, which can help in predicting an eruption.
What is the name of the largest sized tephra?
Blocks is the name used for the biggest pieces of tephra. Tephra is produced by a volcanic eruption.
What did Krakatoa measure on the Richter scale?
Nothing. The Richter scale is used to measure the intensity of earthquakes, not volcanic eruptions. The eruption of Krakatoa in 1883 was a VEI 6 in the volcanic explosivity index.
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.
What intensity scale measures volcanoes?
Volcanic Explosivity IndexYou measure a volcanic eruption by the Volcanic Explosivity Index. The largest eruption in recorded history is the eruption of Mount Tambora in 1815. This eruption measured a 7, or super-colossal, on the VEI. This eruption ejected so much material in the atmosphere that it resulted in the Year Without a Summer in 1816. Lake TobaThe last super volcanic eruption was Lake Toba approximately 73,000 years ago. This eruption is theorized to have caused a worldwide catastrophe.
What are two pieces of evidence used to support the theory that dinosaurs became extinct as a result of volcanic eruption about 65 years ago?
The dinosaurs died by a giant asteroid that hit Mexico.
Are there any uses for the gases given off from molten lava or volcanoes?
There are currently no uses for volcanic gases economically, but a sampling of the gases could be used in monotoring volcanic activity.
