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.
One writer asked you what papers he needed to keep on a house he has owned since 1988, including a couple of refinances. That made me wonder what papers I need to keep on houses my wife and I have bought and sold and no longer own. We purchased our first house in 1999 and sold it in 2002. We purchased our second home in 2002 and sold it in 2007. We also owned a rental home that we sold in 2007. What, if any, paperwork should we still keep? For example, do we need to keep the deeds or the title insurance policies?
