Please keep in mind: although these videos were shown on the Public Broadcasting System channel (KQED, Channel 9 for almost all of us), there may be some sensitive images like human suffering since the documentaries covered real events (i.e., 2010 Haiti earthquake). Furthermore, there are about eight commercials per video; they CAN be skipped after a few seconds.
It is recommended that you watch the videos with your child. You may learn something new. :)
Video #1: PBS NOVA's "Deadliest Earthquake"
In 2010, several epic earthquakes delivered one of the worst annual death tolls ever recorded. The deadliest strike, in Haiti, killed more than 200,000 people and reduced homes, hospitals, schools, and the presidential palace to rubble. In exclusive coverage, a NOVA camera crew follows a team of U.S. geologists as they enter Haiti in the immediate aftermath of the tragedy. The team hunts 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 U.S., one day lead to a breakthrough in predicting quakes before they happen? NOVA investigates compelling new leads in this profound scientific conundrum.
Millions of people around the world live in the shadow of active volcanoes. Under constant threat of massive volcanic eruptions, their homes and their lives are daily at risk from these sleeping giants. From Japan’s Mount Fuji to the "Sleeping Giant" submerged beneath Naples to the Yellowstone "supervolcano" in the United States, we will travel with scientists from around the world who are at work on these sites, attempting to discover how likely these volcanoes are to erupt, when it might happen, and exactly how deadly they could prove to be.
A team of scientists clambers down into the steep crater of an active volcano in central Africa, a lake of molten lava seething far below. The team’s mission is to explore this deadly mountain up close to find out when and why it is likely to erupt next. The lives of half a million people living directly in its shadow are at stake.
In January 2002, the ground close to the city of Goma in the Democratic Republic of Congo split open and rivers of lava swept through entire neighborhoods, killing some 100 people and leaving 120,000 homeless. The volcano towering over the city, Mount Nyirangongo, had awoken again. Now French volcanologist Jacques Durieux and his team worry that, next time, deadly lava could erupt from cracks directly under the city itself.
Volcano Under the City reaches a stunning climax as Durieux’s team struggles to capture a sample of furiously boiling lava from the heart of the volcano. The crater walls crumble and Mount Nyirangongo belches poisonous gas as the scientists put their lives on the line to retrieve their vital data.
