Venture into the danger zone of two volcanic craters posing widely divergent threats. Hawaii's Kilauea is a shield volcano that threatens communities with its slow-but-relentless lava flow, while the Sumatran Sinabung is a stratovolcano delivering carnage via a sudden and explosive surge of superheated gas and rock.
In February 2013, a hole opened up beneath a home in Florida, and swallowed a man. Jeff Bush was asleep when a sinkhole opened up beneath his bedroom. Despite the efforts of his brother to rescue him, Jeff was never seen again and his body was never recovered. Professor Iain Stewart travels to Florida to try and understand what killed Jeff, and why the geology of this state makes it the sinkhole capital of the world.
Sonic Sea is a documentary about the devastating impact of industrial and military ocean noise on whales and other marine life. The film begins with a mystery: the unexplained stranding and mass mortality of several species of whales in the Bahamas in March 2000. As the mystery unfolds, the film explores the critical role of sound in the sea, and the sudden, dramatic changes human activity is inflicting on the ocean's delicate acoustic habitat -- changes that threaten the ability of whales and other marine animals to prosper, to function, and ultimately, to survive. Sonic Sea features several charismatic scientists, including Ken Balcomb, the former Navy pilot and acoustics expert who proved to the world that naval sonar is killing whales, as well as the musician and environmental activist, Sting, whose moving interview connects the sonic world of marine life with our sonic world on land. The film offers solutions (and, by extension, hope) for a quieter ocean, and underscores that the ocean's destiny is inextricably bound with our own.

In just one devastating month, Houston, Florida, and the Caribbean were changed forever. In summer 2017, three monster hurricanes swept in from the Atlantic one after another, shattering storm records and killing hundreds of people. First, Harvey brought catastrophic rain and flooding to Houston, causing $125 billion in damage. Less than two weeks later, Irma lashed the Caribbean with 185 mile per hour winds - and left the island of Barbuda uninhabitable. Hot on Irma's heels, Maria intensified from a Category 1 to a Category 5 hurricane in just 15 hours, then ravaged Puerto Rico and left millions of people without power. As the planet warms, are these superstorms the new normal? How well can we predict them? And with hurricane season just around the corner, does the U.S. need to prepare for the reality of climate refugees? NOVA takes you inside the 2017 superstorms and the cutting-edge research that will determine how well equipped we are to deal with hurricanes in the future.
