Read about recent seismic activity in Israel. Apparently this one cracked the Knesset.
It was less than 4 on the Richter scale, and no-one even felt it. People did not 'stream' into the streets, like that article says. And, also, Israel has been the focus of many earth-quakes, since it sits right on the African-Syrian tactonic border. If the wall hasn't fallen down yet, I doubt it ever will. Besides, reinforcements have been made, and will continue to be made to assure the survival of that historic and religious monument.

Anyone saying stuff about some apocalyptic earth-quake is a doom-sayer, and nothing more. There's no way to predict earth-quakes, let alone 50 (!) years in advance.
