Bam Earthquake

Hamid Sadeghipour


I had a chance to travel for the first time from Kerman to Bam by car. After some kilometers a mountain chain appeared at our east side of the road and was with us to Bam city. The distance between Kerman and Bam is nearly 180 kilometers. When we traveled 50 or 60 km I saw a big fault on the mountain. The mountain chain was separated in two along the direction of the north- west to south- east parallel to the road. A clear broken mountain could be seen on the eastern part. The eastern part was creating a rift hidden and covered by falling western part on the feet of the eastern part over the rift. This rift has a narrow width near bam and wider width near Kerman. Till bam I couldn’t notice anything else. I had a launch with my friend and went to Arg-e-Bam mud city. Bam has at least 2000 years of history and remained intact while constructions continued till some 100 years ago. With advent of the transport the new roads and means the mud city became a tourist attraction. The mud remained intact due to few 60 mm rain per year. The city was destroyed completely in the earthquake of December 2003.Besides, the Bam city itself that you know had near 50000 dead. The remaining walls in the mud city were inclined toward north-west. I made an experiment that while my friend helped me. I placed a small piece stone on a piece of paper and dragging the paper to south- east and the stone felt in the some direction the walls declined. It is clear we have a drag force from Indeian subcontinent toward Asian plate. I attended some lectures in the year 2004 on Bam earthquake, therefore after paying a visit to the mud city I paid a visit to the river flowing in the North of this mud city. All the building around the a wide area, the river site, at 2004 were destroyed. It is good to mention that Iran was an ocean with sediments covering everything. The gentleman offering his book and a visitor mentioned that the military base in the middle north of the mud city is built over a big rock and that is why it remained safer. I think it is possible that a big stone felt from the sky and later with Indian subcontinent move some of the sedimentary cover of the ocean; much more ancient mountains came to the surface. This cover near Bam, due to movement of Indian subcontinent moved to east and as the river was clearly weakens by water flow collapsed. It is good to know that water is brought to Bam for agriculture by chains of the wells as well as south western mountains water sources. It will be good to make some piles across the river for more safety. As later I tried to study more Bam earthquake I noticed Taftan volcano further in the south- east of Bam. It had eruptions in 1902 and 1993. With the year 2003 the event of the earthquake and earthquakes of nearly 1st and 3rd December 2013 with 2.5 and 3.5 Richter, we can count the days between these events and dividing by 466.666 days of volcanic year, I explained in older articles, we can find a significant relation of volcanic action over these events. Then, it is a volcanic and depressive action of a fault. I tried to see the relation with Afar volcanic region of eastern Africa. The volcanic rift is along a line from Congo to Etiopia/Eritrea. If you continue the line over this rift you arrive to south of Fars and Bushehr provinces. I saw a 3D satellite radar measurements of how the ground moved in September 20054 between Dabahu and Gab’ho volcanoes. The picture shows the lines of forces due to separation forces these volcanoes were producing. It is like mountains of Fars and Bushehr Provinces and Kerman and “Zagros Chain” Chain Mountains, the separation of a land in between. It us good for Iran, UAE Kuwait and Iraq to follow east African volcanoes and cooperate with these governments from Congo to Eritrea. Great Britain, France and Switzerland do their advanced research in these fields as I know.
