Earthquakes have been one of the signs
of the coming of Jesus for many
centuries.

They have been slowly increasing:
115 15th century
253 16th century
378 17th century
640 18th century
2119 19th century
and in the 20th century they have been at
different places at close to the same time.
One right after the other, large and small.

"And great earthquakes shall be in divers
places,....." Luke 21: 11
