What intensity scale measures volcanoes?

Answer 1

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.

Answer 2

The Volcanic Explosivity Index (VEI) is a scale used to measure the explosiveness and intensity of volcanic eruptions based on factors like volume of erupted materials, height of the eruption cloud, and duration of the eruption. It ranges from 0 to 8, with higher values indicating more powerful eruptions.

Answer 3

Vulcanologist's use many different types of tools to measure different aspects of volcanic behavior. Seimometers are used to measure earthquakes from the volcano. GPS, traditional surveying equipment, such as theadolites, and satellite imagery are all used to measure the swelling and deflation of volcanoes. Many different types of equipment, such as COSPEC's, are used for measuring the different types of gasses that come out of volcanoes. Plus, this is a developing science, so every year there are new tools developed to study volcanoes.

Answer 4

The most common method of measuring the intensity of a volcanic eruptions V.E.I. or volcanic explosivity index based on the volume of material ejected, the hight of any plume that forms, and observations of force.

At the low end is a 0, with no explosive force where lava simply flows out of a vent. Such eruptions are referred to as Hawaiian or effusive.

At the high end is an 8 which is produced by a supervolcano with significant global effects. No such eruption has occurred in recorded human history, though geologic records point to a several such eruptions in the past few million years.
