Insomniac-Net Questions -- Friday[34], Aug 21, 2015
Tonight's Topic: "It's TorF Trivia (Killer Lake Nyos)"
    Good morning/evening, everybody! Thank you for joining us tonight.
    We hope you'll discover something interesting during the time we spend together on the Insomniac Net for the next 90+ minutes.
        -- The ever-delightful Shelley [KF7TBA] and just plain old LW [K7LWA] (email K7LWA.INS@gmail.com).
    (Please Note: The Net Controller's Answers are always CORRECT (even if they aren't every time!)

    It's that time again:  Some TRUE or FALSE ("TorF") Trivia -- about a tragic event that occurred 29 years ago today in Cameroon, West Africa.
    Around 9:30 PM on August 21, 1986a cloudy mixture of carbon dioxide (CO2) and water droplets rose violently from Lake Nyos -- the 800-ft (200m) deep volcanic crater on Mount Cameroon -- and spilled out of the crater and swept down adjacent valleys.
   Since this 100-foot (50m) thick deadly cloud descended downslope at a rate of 12-30 MPH (20-50 KPH) and covered a distance over 15 miles (23 km), it killed over 1700 people, thousands of cattle, and many more birds and animals in the villages and valleys at the base of the volcano.
    Many of the victims suffocated in their sleep.
    Just two years earlier, at another Cameroon volcano, Mount Monoun, 37 people were killed by a similar deadly carbon dioxide (CO2) expulsion from that volcano's crater lake.
    The tragedy of Lake Nyos might have been avoided; however, unfortunately, the research into the 1984 Monoun disaster was never made public until after 1986.
    So, accordingly, for tonight's topic, how much do you know about volcanic killer lakes?
    Please give us your best answer for each of the following 3 TRUE or FALSE questions, by using the (reuseable) answers of "A"=TRUE or "B"=FALSE.
    Good Luck and remember, YOU are always a WINNER with us, regardless of your actual answers!
    OK, grab those oxygen tanks and run -- don't walk -- for higher ground!

Question #1: The reason the carbon dioxide (CO2) clouds are deadly to humans (and other animals) is that CO2 is 1.5 times denser than air -- which sinks and pushes breathable air out of the way -- and, in most cases, can cause suffocation within a few minutes -- True or False?
        A. True, or
        B. False.
 Question #2: Since 1986, many scientists investigating volcanic killer lakes have concluded that the carbon dioxide (CO2), trapped at the bottom of these lake, had suddenly risen to the surface, over-topped the crater rim, and flowed down the volcanic slopes. They called their theory: "Lake Harmonic Inversion" -- True or False?
        A. True, or
        B. False.
 Question #3: The Nyos disaster promoted a survey of deep lakes in Africa and Indonesia. Fortunately, as of 2002, no other large, deeply-cratered volcanoes with similar killer lakes have been found -- True or False?
        A. True, or
        B. False.

=================
    ++ QUOTES OF THE DAY ++  -- from Bill Evans (US Geological Survey):
"This lake really is a timebomb. The gas that comes into this lake every day increases the danger of an eruption, so unless steps are taken to remove that gas it's almost a certainty that the lake would erupt again."
