Natural Disasters in USA 1980-2011

The trend lines are clearly upward in all but one category.

The chart appeared in a review published in July of this year by Munich Re, one of the world’s largest re-insurers. Their definition of a disaster “event” is based on an algorithm using data about fatalities, total overall losses, and insured losses. The entire review is fascinating and full of charts like this one.

Red – Geophysical (earthquakes / volcanoes)
Green – Meteorological (storms / blizzards)
Blue – Hydrological (floods / landslides)
Orange – Climatological (heat wave / drought / forest fire)

    The chart is for the first six months of each of the years, including 2011. If you look at the original presentation, this graph is labelled “Number of Events (January – June Only)”.

    I haven’t figured out what they are counting as “events”, though.

    Thanks for the correction. I’ll try to find out how they define “Events.”
