Now, listen to Part One of the interview.
W: Welcome to our program. I’m Linda Poon. This week we bring you a story on dangerous buildings. Sometimes science isn’t enough. Technology can be expensive or unavailable or impractical. In the case of engineering buildings in earthquake zones, these shortcomings can be deadly. Today, Roger Bilham will talk with us about the dangers of poorly built buildings in south central Asia and what roles science and technology can play to alleviate conditions there.
M: In our short perspective,(1-1)we recognize some of the issues of earthquake in South Asia, which have been central to our studies, but we focus on the rather special problem, which is the fragility of dwelling units throughout the region—houses which are capable of falling down in the night without an earthquake even sometimes.(1-2)In our study we are concerned not only about the absence of seismic-resistant building codes but, in many cases, an absence of any building code.
W: So your title talks about buildings as weapons of mass destruction, but you focus right on a specific part of the globe as being especially high risk. Can you describe the tectonic situation in South Central Asia?
M:(2-1)The tectonic situation is particularly malicious because many of the earthquakes that occur in this part of the world occur on dry land. That sounds a rather obvious thing to state,(3)but if you think about some of the big earthquakes that have occurred in the last several years, they’ve occurred on plate boundaries. They’ve occurred where there’s an ocean, a seaside, on one side and on the other side you have people.(2-2)In Southeast Asia, much of it is in a very wide collision zone where the earthquakes are occurring far from the ocean. And, of course, that’s where the people live.
W: Right. You provide some numbers in your perspective about the number of deaths—and I was really stunned over the timescale that you’re able to talk about. Can you share those numbers?
M: Yes.(4)We calculate very roughly about a million people have been killed by earthquakes in the last thousand years. Of course details of the older earthquakes are sometimes a bit doubtful.(5)But the more recent ones have been occurring not in Iran where most of the deaths have historically occurred but in parts of India and Indonesia, Burma, and so on. So there’s been a kind of shift in the fatality counts as a function of longitude. And we were puzzled about this. It could be simply a coincidence, but we can see some underlying reasons. One, of course, is that populations have increased enormously in this part of the world, particularly in India and in Pakistan too.
