Tsunamis, earthquakes, tornado's, (super)volcano's, flood, famine, heat, hurricanes, and all other natural disasters have been around longer than humans & will be here after H.Sapien has moved on to other species. or dies out altogether. The threat we have today is hyper-sensitivity to these disasters because of overt coverage by a national media that suddenly has 24 hours per day, 7 days per week & 365+ day per year to fill the TV screen to keep mom & pop Jones &/or Saddam Hussein entertained. Instant access to coverage of flooding in India has a more immediate impact than 10 day old newspaper photos. The threat is to our psyche, except in the case of those DIRECTLY affected, in which, I'd guess, 95% know of the threat before it happens & choose to ignore it. I was happy living in an earthquake zone, now I'm in tornado alley & an area prone to blizzards. Q lives in the path of approxiamately 12 hurricanes per year. Postcode is going to get blown to bits by an overactive volcano. Collectively and singularly, everybody here is at threat from some natural disaster.survival of the fittest -cruel & devastating & necessary.
