Scientists Expose 'Buried' Fault That Caused Deadly 2003 Quake In Bam, Iran
they figured out that the earth quake in iran was not a real natural disaster it was buried fualts
that were not so hidden. These fualts caoused a 6.6 earth quake which had killed over 30,000 people.The seismic and satellite studies showed that the fault under Bam had slipped by about 2 to 3 meters at the time of the earthquake. When scientists from Iran went out in the field after the earthquake, the cracks they found at the surface only showed 25 centimeters of slip or less. If indeed there had been 2 to 3 meters of slip at depth, the surface must have somehow absorbed that slip. Which would almost have been impossible.This study is helping the researchers find the future behavior of the fault. Initially, they were concerned that if stress at depth was not relieved at the surface, then a earthquake could result. The rupture's stress was absorbed in the damage zone, the researchers believe the fault that shook Bam in 2003 is no longer a risk.
