one can touch the Muslims who are loyal to the country. “From designing basic bags.For the past year Tara Hutchinson has been trying to figure out what will happen to a tall building made from thin steel beams when “the big one” hits To do that she has erected a six-story tower that rises like a lime-green finger from atop a shrub-covered hill on the outskirts of San Diego California Hundreds of strain gauges and accelerometers fill the building so sensitive they can detect wind gusts pressing against the walls Now Hutchinson just needs an earthquake In most of the world this would be a problem Even here where a major fault runs right through downtown the last quake of any note struck 6 years ago and was centered in nearby Mexico But Hutchinson a structural engineering professor at the University of California (UC) San Diego doesn’t need plate tectonics to cooperate This summer she has an appointment at one of the world’s biggest earthquake machines This device—a sort of bull ride for buildings—is one in a network built around the United States over the past 15 years to advance natural disaster science with more realistic and sophisticated tests Costing more than $280 million the National Science Foundation (NSF) initiative has enabled scientists to better imitate some of the most powerful and destructive forces on Earth including earthquakes tsunamis and landslides The work has led to new building standards and better ways to build or retrofit everything from wharves to older concrete buildings Scientists have gained insights into how quakes damage pipes in walls and ceilings and how to help quake-proof highway ramps tall steel buildings parking garages wooden homes and brick walls to name a few That expansion continues today In a new $62 million 5-year program the network of doomsday machines is expanding to simulate hurricanes and tornadoes and is joining forces with computer modeling to study how things too big for a physical test such as nuclear reactors or an entire city will weather what Mother Nature throws at them Scaling down disasters Credit California’s Northridge earthquake for helping set this in motion The 1994 quake centered near Los Angeles killed 72 and cost an estimated $25 billion in damages In its aftermath a report commissioned by Congress warned that the country needed a more systematic approach to studying how to reduce damage from earthquakes NSF responded with the $82 million Network for Earthquake Engineering Simulation The money funded a construction spree at 14 sites around the country Another $200 million paid for operating the sites through 2014 That included UC San Diego which unveiled the world’s largest outdoor shake table in 2004 Researchers at Oregon State University Corvallis unleash tsunamis in a wave basin Aurora Photos/Alamy Stock Photo Descriptions of these disaster labs are often couched in superlatives: the biggest the longest the most powerful In addition to the San Diego facility the projects funded under the original program and its successor the Natural Hazards Engineering Research Infrastructure (NHERI) include North America’s largest wave flume for studying tsunamis at Oregon State University Corvallis; the world’s largest university-based hurricane simulator at Florida International University in Miami; and at UC Davis the world’s biggest centrifuge for making scale models mimic the stresses on tons of buildings rock and dirt—crucial information for assessing how structures will weather earthquakes and landslides More than bragging rights is at stake When it comes to learning how buildings cope with the forces generated in a natural disaster size often does matter For example the way soil particles stick together an important factor in landslide risks depends on how much mass is pushing down on them Similarly it’s nearly impossible to build accurate tiny versions of rebar: steel rods embedded in concrete structures that are critical to building performance Similar difficulties arise with measuring how hurricane-force winds interact with a building “You can’t take a real building and scale it down to one-tenth and put it in a wind tunnel The physics doesn’t work” says Forrest Masters a wind engineer at the University of Florida in Gainesville who directs his university’s share of NHERI That includes a machine capable of subjecting 5-meter-tall walls to the air pressures found in a 320-kilometer-per-hour hurricane and a wind tunnel whose floor can be modified to see how different terrain influences the way wind interacts with structures Computer models too can fall short in accurately reproducing all the forces at play as say a bridge twists and sways in an earthquake So many different pieces in the bridge are pulled in so many directions at once that it can fail in unpredictable ways causing models to misrepresent reality In 2010 a contest at the San Diego shake table pitted 41 teams of experts running models against a real-life test of a 7-meter-tall bridge column topped with 236 metric tons of concrete blocks The computer results were all over the place says Stephen Mahin a structural engineer at UC Berkeley who helped orchestrate the event On average they underestimated how much the column would sway by 25% “You can’t quite trust the computer results yet” Mahin says A building awaits its ordeal on the shake table at the University of California San Diego Erik Jepsen/UC San Diego One morning in mid-May Hutchinson inspects her building in the final stages of preparation for the test She points to tiny gaps that have sprung open where metal ceiling joists meet the wall in a first-floor room That happened during a minor preliminary shake her team delivered to the building a day earlier It’s the kind of thing that could make a difference in how load is shared between pieces of the building and how much damage the building suffers in the next temblor And it wouldn’t show up in a computer model “You’re not going to account for every screw” she says “Look at how subtle this damage is” Shake rattle and roll Devising a machine that can pack the same wallop as a magnitude-80 earthquake or a category-5 hurricane isn’t easy or cheap A look under the hood of San Diego’s shake table illustrates the kind of mechanical muscle needed Joel Conte an engineering professor who oversees the shake table operations leads the way into a cavernous under-ground room filled with machinery A 20000- liter metal tank holds the hydraulic fluid that drives the entire system Two pumps slurp the fluid from there into a bank of 50 slender black cylinders reminiscent of street light poles at pressures reaching 34000 kilopascals (5000 pounds per square inch) That high pressure is crucial generating enough force to swiftly move an entire building Conte turns down a passageway tracing the path of the fluid through steel pipes 30 centimeters across and into a room dominated by a mass of steel resembling the hull of a flat-bottomed boat This is the epicenter A metal plate 5 centimeters thick 12 meters long and nearly 8 meters wide sits overhead bolted to the steel underbelly At either end an actuator that looks something like a car’s shock absorber but is as thick as a man’s torso extends from this structure to the concrete wall When the commands come from computers in a nearby building the actuators will jerk to life the hydraulic fluid driving them back and forth The plate pushed and pulled between them will slide across metal sheets polished mirror-smooth at speeds of up to 18 meters per second Voilà Instant quake “The real world you cannot count on it” Conte says “You cannot say ‘Oh I’m going to sit and wait for the next earthquake in front of this big building and I’m going to invest a lot in sensors’ You may have to wait 30 40 50 years So you produce an earthquake” Since its construction for $10 million the shake table has tested a four-story concrete parking garage a wind turbine and a five-story concrete building complete with elevator and stairs among other things The tests have shown that special inserts can increase resilience by allowing a building to move over its foundation and that modular concrete floors can behave erratically unless they have additional reinforcement They have also revealed how tall wood-framed buildings fail and how reinforcements can strengthen old brick buildings Back in his office Conte gleefully clicks through the “best of” video highlights A four-story wood building twists and splinters to the ground A parking garage teeters back and forth like a rocking chair A split screen shows two identical rooms filled with hospital beds and medical equipment One is in a building outfitted with padded foundations that help it absorb an earthquake’s shock; the other isn’t As the video runs beds in the regular building suddenly lurch back and forth before toppling over In the other they barely move In the current test Hutchinson wants to see how a building six stories tall made from lightweight steel performs during and after an earthquake She thinks it could do well partly because it’s lighter than a concrete building of the same height giving it less mass to generate damaging forces during a quake Today building codes allow this type of construction to be just shy of 20 meters tall But the tallest building really put to the test was only two stories high The structure modeled after an apartment building is destined for a multistage torture test Hutchinson and her colleagues will first put it through a simulation of several quakes including Northridge and a 2010 magnitude-88 in Chile Then they will set fires in parts of the building to see how it holds up in a blaze triggered by quake damage Then they will shake the building again in a mock aftershock hard enough that it might collapse The results aren’t just of academic interest Sponsors of the test include manufacturers of the steel construction parts the insurance industry and state government “There’s nothing like a full-scale test” says Richard McCarthy executive director for the Cali–fornia Seismic Safety Commission in Sacramento a government commission that advises policymakers It contributed $100000 to the event he says partly with an eye toward potential changes to building codes governing construction using these materials Conte is now lobbying state officials for a $14 million upgrade that would allow the machine to run even more realistic tests Right now it can move only back and forth in two directions; new hardware would add up-and-down side-to-side and diagonal motions enabling it to move in every direction—like the world’s biggest shake table an indoor facility in Miki Japan Up next: Hybrid simulations Scientists are trying to go even bigger by marrying such physical tests with computer models The resulting “hybrid” simulations can test massive structures too big to fit inside any test facility says James Ricles a civil engineer at Lehigh University in Bethlehem Pennsylvania His lab which is part of the NSF network tests well-understood parts of a structure with computer models but stages physical tests for parts that the models can’t handle In a feedback loop measured in milliseconds sensors from the physical test send data to the model which adapts and sends new signals that tell the machines driving the physical test how to tweak their next moves Ricles’s lab simulated the behavior of an elevated highway during an earthquake by physically testing the concrete columns while testing a virtual model of the bridge deck in a computer He recently applied the same strategy to testing a design meant to allow a steel building to rock back and forth rather than bend during a quake A four-story chunk of the building stood in the lab; the rest of it existed only in the microprocessors of a computer Destruction is a definite part of the work’s appeal says Gilberto Mosqueda an engineering professor who runs hybrid tests at UC San Diego: “You build these models and essentially you shake them till you break them” But the mountains of data generated by the tests also open the way to more sophisticated numerical models that could one day do some of the work of the doomsday machines Whereas the earlier NSF program focused on big testing platforms the NHERI initiative is putting more money into the virtual side The University of Texas Austin won $137 million to build a data repository and software platform to store information from years of field tests In the future engineers should be able to tap data in the digital repository to boost the accuracy of their computer models And NSF will soon issue an $11 million award for a computational modeling and simulation center “Will we get to the point where we can just model everything and have confidence That may still be a long way off” says Joy Pauschke a structural engineer and director of the NSF program that funds the testing work in Arlington Virginia “But hopefully as we test and improve models we start moving towards having better capabilities with the computational modeling” Berkeley’s Mahin—whose 2010 contest exposed the shortcomings of models—now also foresees bright prospects for modeling Advances in machine learning and cloud computing he predicts will lead to models capable of simulating not just single buildings but entire communities Unleashing “virtual disasters” could then enable researchers and government officials to grasp the region-wide effects of a major quake or storm and decide which measures today would prevent the most damage “In 20 years you can model a whole city in a very complicated way I think” Mahin says “There’s a great hope this analysis can help mitigate the damage from future natural disasters” Additional articles in our Natural Hazards feature package:

involved with questions about whether there was life after death This has been encapsulated in an essay authored by Tagore scholar Amitabha Choudhuris essay entitled Rabindranather Paralok Charcha that explores Tagores involvement with the supernatural and with attempts to communicate with the dead The theme for the film is an extremely challenging one With such a themea movie can either be powerful or it can just be a pretentious attempt to focus on the supernatural from the Bards perspective Unforunatelythis format is just not the kind that this director can handle Choudhurywho has written the script and story in addition to having directed the filmperhaps should have stuck to the documentary format and done away with the fictional part which is neither convincing nor reverential to the poet and his philosophy The first half deals with a bunch of studentswho know very little about Rabindranath Tagoreand tag along with Jeeta filmmaker who goes to Shanti Niketan to

have been dispensed with to give more footage and depth to the supernatural preoccupations of the poet The fictional segmentwhich aims to show how the young bunch of kids finally become aware about
