Earthquake!

The words of Amos, who was among the herdmen of Tekoa, which he saw concerning Israel in the days of Uzziah king of Judah, and in the days of Jeroboam the son of Joash king of Israel, two years before the earthquake.  --Amos 1:1 KJV

Some modern scholars refer to the earthquake mentioned here as the "Amos Earthquake."  Geologists, seismologists and archaeologists have verified that this quake occurred in 760 B.C. which would have been during the "days of Jeroboam."

The quake was estimated at 7.6 to 8.0 on the Richter Scale and its epicenter is placed roughly 60 miles north of the Sea of Galilee.  It was the largest temblor along that fault in the past 4000 years.
