Volcanic smog prediction now possible using computer model

A computer model has been developed for the dispersion of volcanic smog (vog) which forms when volcanic sulfur dioxide gas interacts with water and coverts it to acid sulfate aerosol particles in the atmosphere.

A paper published in the Bulletin of the American Meteorological Society used measurements of the amount of sulfur dioxide (SO2) emitted by Kilauea volcano, Science Daily reported.

For Kilauea volcano measurement, scientists developed an ultraviolet spectrometer array to provide near real-time volcanic gas emission rate measurements.

Scientists from the UH Mānoa School of Ocean and Earth Science and Technology (SOEST) in collaboration with researchers at the Hawaiian Volcano Observatory claims that the dispersion of the vog plume over time are sufficiently accurate to provide very useful guidance.

Researchers from the Department of Earth Sciences at Royal Holloway, University of London have already developed a new method of predicting volcanic eruptions by collecting geological and historical data on previous eruptions of the volcano.

Have you ever witnessed an earthquake? What effect did it have on you?

Q: Have you ever witnessed an earthquake? What effect did it have on you? In general, the word earthquake is used to describe any seismic event either natural or caused by humans. Here we are talking about the natural cause. A natural disaster is a sudden natural event triggered by environmental factor which can cause loss of life or property damage. Earthquake is one of the common natural disasters worldwide that has claimed several lives causing huge economic losses. You might have also witnessed an earthquake in your time.
