TED-Ed educator Alex Gendler explains the origin of tsunamis and why the term “tidal wave” is a bit of a misnomer.
The immense swell of a tsunami can grow up to 100 feet, hitting speeds over 500 mph — a treacherous combination for anyone or anything in its path. Alex Gendler details the causes of these towering terrors and explains how scientists are seeking to reduce their destruction in the future.
Have you ever wondered what would happen if everyone on Earth would jump at the exact same time? Then watch this video to find out.
A Japanese company has developed a material that cures within one minute and has a tensile strength more than two times that of concrete. For cities affected by natural disaster, this “CO2 Structure” could help reconstruction happen faster.
Concrete usually takes 28 days to cure to its full strength. By blowing CO2 into silica, TIS Partners LTD was able to make the silica into a substance as hard as brick, as reported by DigInfo TV (via Gizmodo). TIS Partners President Norihide Imagawa said they then increased strength by adding epoxy or urethane.
YouTuber Darwinfish105 (who made that stunning time-lapse video of Japan’s Gundam statue) now shows us the lights of Tokyo before and after March’s earthquake and tsunami. The metropolis’ lights have dimmed due to power shortages and energy conservation efforts.
Wow… repaired in just 6 days! I guess Japan doesn’t have unions.
Are we still rebuilding from Katrina?
Japan’s world-class transportation infrastructure couldn’t withstand this month’s 9.0-magnitutde quake, but their construction teams are still amazing. This stretch of highway was repaired in just six days by a Herculean road crew. This is the triumph of Japanese engineering.
Emerging coverage from Japan offers a moving example of ultimate dog loyalty, and clearly illustrates the challenges faced by animal victims of the earthquake and tsunami.
The dogs were picked up after the video was shot, and are in the care of a local shelter.
