two points to note, we are in a building (*increasing size, frequency, intensity) of earthquakes which began in 1940 and really saw accelleration in 1975. Now the most recent period of deadly quakes has had a huge (estimated damage 250 million dollars - US, 300 million in Iran) impact on global economic strength in just 5 days time.
The guys at halfpasthuman have been working this hyperspatial geometry for solar cycle predictions and now feel that they have enough data to start making predictions about potential impacts on earth and when such impacts would most likely occur.
the link to their first such prediction is

Privately they have said that they are looking at calc's for potential insurance/damage costs for 2004 that are staggering. Something like 10 times the impact of the previous worst year in 1998.
