Deadliest Earthquakes (#3801H) Duration: 55:31 STEREO TVPG (Secondary audio: DVI)
In 2010, epic earthquakes all over the planet delivered one of the worst annual death tolls ever recorded. The deadliest strike was in Haiti, where a quake just southwest of the capital, Port-au-Prince, killed more than 200,000, reducing homes, hospitals, schools, and the presidential palace to rubble. In exclusive coverage, a Nova camera crew follows a team of US geologists as they first enter Haiti in the immediate aftermath of the tragedy. It is a race against time as they hunt for crucial evidence that will help them determine exactly what happened deep underground and what the risks are of a new killer quake. Barely a month after the Haiti quake, Chile was struck by a quake 100 times more powerful, unleashing a tsunami that put the entire Pacific coast on high alert. In a coastal town devastated by the rushing wave, Nova follows a team of geologists as they battle aftershocks to measure the displacement caused by the earthquake. Could their work, and the work of geologists at earthquake hot-spots around the US, one day lead to a breakthrough in predicting quakes before they happen? Nova investigates new leads in its investigation of a deadly scientific conundrum.

Colosseum - Roman Death Trap (#4206H) Duration: 55:41 STEREO TVPG-V
One of the ancient world's most iconic buildings, the Colosseum is a monument to Roman imperial power and cruelty. Its graceful lines and harmonious proportions concealed a highly efficient design and advanced construction methods that made hundreds of arches out of 100, 000 tons of stone. But this building is more than just an architectural giant - in its heyday it was filled with unbelievable spectacles and 50,000 cheering fans. In its elliptical arena, tens of thousands of gladiators, slaves, prisoners, and wild animals met their deaths. Ancient texts report lions and elephants emerging from beneath the floor, as if by magic, to ravage gladiators and people condemned to death. Then, just as quickly, the Colosseum could be flooded with so much water that ships could engage in sea battles to the delight of the crowd. Could these legends be true, or are they just myth?
Now, with extraordinary access to one of the world's most protected world heritage sites, archaeologists and engineers are teaming up to recreate ancient Roman techniques to build a 25-foot lifting machine and trap door system capable of releasing a wolf into the Colosseum's arena for the first time in 1500 years. To do it, they will have to decipher ghost-like impressions left on the crumbling walls of the Colosseum's basement by the original lifts and then transform them into working plans for construction. Do they have what it takes to replicate the innovation and ingenuity of the Romans?
Nazi Attack On America (#4210H) Duration: 56:46 STEREO TVPG
Long before 9/11, a far deadlier, little-known attack from the ocean depths struck our shores, lasting three-and-a-half years and claiming 5,000 lives. Now, famed undersea explorer Bob Ballard, discoverer of the Titanic, investigates the wreck of one of the attack craft, a German submarine that lies at the bottom of the gulf just a few miles off New Orleans. U-166 was part of Operation Drumbeat, a highly successful U-boat operation that caught East Coast cities and shipping almost completely unprepared. With state-of-the-art survey gear, Ballard probes the wreck and unravels a dramatic mystery in the official story of the sub's sinking.

Building Wonders: Hagia Sophia - Istanbul's Ancient Mystery (#4204H) Duration: 55:41 STEREO TVG
The soaring dome of Hagia Sophia dominates Istanbul's skyline. Whether serving as Christian church, Islamic mosque, or secular museum, this magnificent building has inspired reverence and awe. For eight hundred years, it was the largest enclosed building in the world; the Statue of Liberty can fit beneath its dome with room to spare. How has it survived its location on one of the world's most active seismic faults, which has inflicted a dozen devastating earthquakes since it was built in 537 AD? As Istanbul braces for the next big quake, a team of architects and engineers is urgently investigating Hagia Sophia's seismic secrets.
Nova follows the team's discoveries as they examine the building's unique structure and other ingenious design strategies that have insured the dome's survival. At the climax to the show, the engineers build a massive 8-ton model of the building's core structure, place it on a motorized shake table and hit it with a series of simulated quakes, pushing it collapse -a fate that the team is determined to avoid in the real world. The Unshakeable Hagia Sophia is a detective story that reveals how this architectural wonder has proven so resilient for so long, and how it came to serve as a proud expression for the great civilizations that adopted it as a symbol.

Secrets of the Sun (#3907H) Duration: 56:46 STEREO TVG
It contains 99.9% of all the matter in our solar system and sheds hot plasma at nearly a million miles an hour. The temperature at its core is a staggering 27 million degrees Fahrenheit. It convulses, it blazes, it sings. You know it as the sun. Scientists know it as one of the most amazing physics laboratories in the universe. Now, with the help of new spacecraft and Earth-based telescopes, scientists are seeing the Sun as they never have before and even re-creating what happens at the very center of the Sun in labs here on Earth. Their work will help us understand aspects of the sun that have puzzled scientists for decades. But more critically, it may help us predict and track solar storms that have the power to zap our power grid, shut down telecommunications, and ground global air travel for days, weeks, or even longer. Such storms have happened before-but never in the modern era of satellite communication. Thid episode reveals a bright new dawn in our understanding of our nearest star-one that might help keep our planet from going dark.
D-Day's Sunken Secrets (#4113H) Duration: 1:55:11 STEREO TVPG
On June 6, 1944, the Allies launched the biggest armada in history to invade the Normandy beaches and liberate Europe from the Nazis. In less than 24 hours, more than 5000 ships crossed the English Channel, along with thousands of tanks and landing craft and nearly 200,000 men. Throughout the operation hundreds of ships sank running the gauntlet of mines and bunkers, creating one of the world's largest underwater archaeological sites.
