Earthquakes continue to increase in frequency and intensity, just as the Bible predicts for the last days before the return of Christ. History shows that the number of killer quakes remained fairly constant until the 1950s - averaging between two to four per decade. In the 1950s, there were nine. In the 1960s, there were 13. In the 1970s, there were 51. In the 1980s, there were 86. From 1990 through 1996, there have been more than 150.
