Disclaimer: This site has been first put up 15 years ago. Since then I would probably do a couple things differently, but because I've noticed this site had been linked from news outlets, PhD theses and peer rewieved papers and because I really hate the concept of "digital dark age" I've decided to put it back up. There's no chance it can produce any harm now.

UNCLAS SECTION 01 OF 02 DHAKA 001976 SIPDIS SENSITIVE E.O. 12958: N/A TAGS: PGOV, EAID, BG SUBJECT: THE SHAKY SEISMIC OUTLOOK FOR BANGLADESH REF: DHAKA 1731 1. (SBU) SUMMARY: Experts forecast a devastating earthquake in Bangladesh in the next ten years. Bangladesh is woefully ill prepared, but the BDG, backed by some academics, is slowly starting to address the associated challenges. END SUMMARY. 2. (SBU) Bangladeshi and foreign experts estimate that the Himalayan Arc tectonic plate line will experience at least seven major earthquakes, of a magnitude greater than 8.0 on the Richter Scale, at different times and in different locations along its length within the next ten years. The intensity of any earthquake near Bangladesh is increased by its relatively loose soil, which amplifies vibrations. When vibrations are heavy enough, soil can liquefy and cause buildings to sink or collapse. Soil liquefaction is being blamed for the April 11 Savar factory collapse (reftel) which officially claimed 61 lives. Dhaka, Chittagong and Sylhet are at serious risk for soil liquefaction, with Chittagong and Sylhet already experiencing regular landslides. Dhaka has at least three smaller fault lines in addition to the Himalayan Arc. 3. (SBU) Dhaka is particularly vulnerable due to its high concentration of old, poorly maintained buildings and new, shoddily constructed buildings, all of which sit cheek-by-jowl in a haphazardly growing city of 13 million inhabitants. Proximity to each other makes these buildings more susceptible to vibrations originating elsewhere. The Ministry of Disaster Management and Relief (MDMR) estimates that 40% of Dhaka's buildings would collapse in a 6.0 Richter Scale earthquake, and a large percentage of the remaining buildings would be damaged, as would other key infrastructure. In 2004, an old multi-story apartment building in Old Dhaka partially collapsed due to vibrations from a nearby construction site. Emergency crews were unable to reach the building or its inhabitants because the street, as is common in Old Dhaka, was too narrow to accommodate emergency equipment. Many if not most buildings and urban areas lack central shut-offs for gas and power supplies, so fire is another major concern. The hydro-electric Kaptai dam, Bangladesh's only dam, was built in the late 1950's and is reportedly unable to withstand a major earthquake; if ruptured, flooding would likely kill thousands. Studies by the prestigious Bangladesh University of Engineering and Technology (BUET) suggest that an 8.0 Intensity Scale (different from the Richter Scale) earthquake could cost Dhaka upwards of $600 million in damages and lost growth, a huge sum for Bangladesh. Recovery periods would be months, probably years, given the country's already woeful infrastructure. 4. (SBU) Dhaka did not have a building code until 1993. Enforcement in the planning and especially the construction phases is lax and often manipulated by corruption. BUET seismologist Dr. Mehedi Ansary, who is part of a BDG committee updating the code, told us that the code now falls short of minimal earthquake standards. The city agency responsible for enforcing Dhaka's building code is Rajuk (a Bangla acronym for "Capital Development Authority"). It is notoriously corrupt, under-trained, and under-staffed, according to businesspersons and other sources. Sixty inspectors and supervisors are responsible for inspecting 300,000 buildings. One consequence of this ratio is that inspectors normally inspect only design plans. If they do inspect a structure, it is generally only to ensure that property lines are intact. Ansary estimates that Rajuk needs at least 300 inspectors with 50, fully-trained, supervisory engineers to do the job right. 5. (SBU) To that end, BUET is now training each year 35 engineers in structural evaluation for seismic safety. Last year's short course drew 50% of its participants from government, including Rajuk and the Public Works Department (PWD), which has the equivalent of Rajuk's mandate for government structures. The PWD is already better trained and equipped than Rajuk, and sent more senior engineers to the training. Ansary reports that some NGOs with an architectural focus have begun looking for ways to assist in retrofitting old buildings in two vulnerable areas of Old Dhaka. CARE-Bangladesh is also working to raise awareness about earthquakes nationwide. 6 (SBU) After the 2001 earthquake in India, the Asian tsunami that barely missed Bangladesh in December, and the Savar factory collapse, there are indications that the BDG is focusing more attention on seismic matters. On April 18, Prime Minister Khaleda Zia declared in a speech that Bangladesh needs more search and rescue equipment and more earthquake resistant buildings. The last issue of the BDG-published "Standing Orders on Disaster" does not contain any reference to seismic or industrial disasters. Instead it is oriented to the yearly floods and storms. However, a new section is being drafted on seismic issues for the next Standing Order, due out in six months. According to the MDMR, one week after the tsunami, an inter-ministerial disaster management coordinating committee was convened and it was agreed that Bangladesh is totally unprepared for an earthquake. Training modules are now reportedly being developed to educate the populace on how to respond in an earthquake. Educational programs on BDG TV are planned for this month, and Public Service Announcements are in development. 7. (SBU) At the Savar factory collapse, Dhaka's emergency response services demonstrated they were ill-prepared for even a single building collapse. They lacked even low-tech items like headlamps, hand-held hydraulic clippers, gloves, and bodybags. The EMT response is also poor. As fire fighters and Army personnel are generally untrained in first aid, local Boy Scout troop leaders stepped in to provide emergency care to survivors until they could be moved to hospitals. But the BDG is trying to build capability. Dhaka's 12 fire stations recently used their own funds to purchase $3.2 million worth of disaster response equipment. At Savar, 48 Dhaka-based fire fighters who had recently participated in USAID-sponsored building collapse response training used the training-grade equipment and their newly acquired knowledge. The Army and the fire department are the primary responders to disasters. The Army, experienced in rolling out effective flood relief packages, has shown it can organize and provide relief for large numbers, but, even though it assumed command at the Savar site, it lacks specific seismic-related skills and equipment. A recent draft of a Seismic Response Plan being developed by the Dhaka city government divides the area into eight zones and dictates responsibility within each zone to either the Army, the fire department, the police, or the paramilitary Bangladesh Rifles. Ansary also wants to open communication lines with Indian engineers and first responders to see how they coped with massive earthquake recovery operations. CHAMMAS
