The information sent by Dr. Ghods about Bam's earthquake was
interesting and deserves to be read carefully. But, it is more
interesting if you know that a number of seismologists in the US
geological survey had already predicted such an earthquake 6 weeks in
advance. In fact, in the subduction zone of Arabian plate near Bandar
Abbas, they had observed a moderate quake of magnitude 4.5. They had
suspected to observe another quake within 6 weeks in central regions.
Bam's quake happened 7 weeks after their subduction zone studies. Of
course, it has not been possible to exactly locate the next quake.
Tectonic dynamics of Iranian microplate punched between Arabian and
main
Eurasian plates is a very interesting topic for research. Even better
than galactic dynamics! A new technology for earthquake prediction
works
based on infra-red imaging, and detecting stressed rocks before they
release their strain energy (according to thermoelasticity equations
stress tensor and temperature correlate as the stress tensor and
refraction tensor do). Some debates, ideas and fictions can be found in
the recent postings on the weblog
http://www.chainrule.blogspot.com  and its archive.

All the bests,
