Well, rumors of earthquakes aren't exactly prophetic but actual earthquakes are. It has often been stated that the worst scenario for the US would be an earthquake along the New Madrid fault:
"Mississippi Delta earthquake: America's Haiti waiting to happen?"
"One of the strongest series of earthquakes ever to hit the United States happened not in Alaska or along California's San Andreas fault, but in southeast Missouri along the Mississippi River."
"In 1811 and 1812, the New Madrid fault zone that zig zags through five states shook so violently that it shifted furniture in Washington, D.C., and rang church bells in Boston. The series of temblors changed the course of the Mississippi River near Memphis, and historical accounts claim the river even flowed backward briefly."
"Geologists consider the New Madrid fault line a major seismic zone and predict that an earthquake roughly the magnitude of the Haiti earthquake (7.0 on the Richter scale) could occur in the area during the next 50 years."
“All the faults are active,” says Haydar Al-Shukri, director of Arkansas Earthquake Center. “We would see an earthquake 10 times larger than the Haitian earthquake or even those in California because of the amount of distance the seismic waves of the earthquake would travel."
"Israel's looming war in Gaza: Can Obama stop it before it starts"
"Next week, or the week after, Barack Obama may well see intelligence reports of tank battalions moving south and west along Israeli highways, and whole infantry brigades setting up camp in the western Negev."
"The countdown to the Second Gaza War has begun in earnest. Date it, if you like, to Sunday, and a coolly terrifying analysis by Yom Tov Samia, former overall Israeli military commander of the Gaza Strip and the adjacent Negev."
There are also rumors of war coming from the northern border:
"Hezbollah and Syria on alert fearing IDF attack on Lebanon"
"Syria and Hezbollah have gone on alert anticipating an Israeli attack on Lebanon, the London-based A-Sharq al-Awsat daily reported on Friday."
"According to the report, Hezbollah has been monitoring with caution the reinforcement of Israel Defense Forces troops along the Lebanon border."
As stated so many times before - the region is just on the brink of war.
