Once a volcano erupts, gases are emitted and released into the atmosphere. During large eruptions, gases have actually caused global climate change. In other systems, gases are emitted continuously into the atmosphere from soils, volcanic vents, fumaroles and hydrothermal deposits.he spectrometer is designed to measure the concentration of sulfur dioxide (SO2) in the volcanic plume that is emitted from the volcano. The device requires a standard, from which to analyze the ultraviolet light absorbed by the SO2 molecules in the plume.
Once you've done that, shred the paper documents (to avoid ID theft) or securely trash electronic files unless you need them to support your tax return. Keep insurance policies and investment statements until new ones arrive. Keep for a year or more. You'll want to hold onto loan documents until the loan is paid off.

You may want to keep birth certificates, death certificates, wills, and insurance policy information in a safety deposit box at your local bank..
