Scientists trying to understand the Tohoku-Oki earthquake that took place March 11th, 2011 and what made it so devastating. This earthquake was the largest and most destructive in the history of Japan. Many people drowned in a tsunamis that in were more than 30 metres high. These natural disasters killed more than 20,000 people, making it one of the most deadly natural disasters in the country's history. The tsunami went into the Fukushima Daiichi nuclear power plant, which released large amounts of radiation to the ocean. Studying this event may help scientist understand how it formed and how to protect the population of Japan from the earthquakes.

Scientists found that Japan sits on a jumble of tectonic plates which may be one of the most dangerous places possible when it comes to earthquakes. When any one of the plates move, the movement can cause an earthquake and tsunami. Scientists put a series of linked pressure sensors installed on the ocean floor in Japan. This could help give people as much as 10 minutes to evacuate, which can help save people's lives. This small time gap can help prevent the amount of deaths and disaster in the Tohoku-Oki earthquake.
A new NASA forecasting model based on satellite measurements is allowing researchers to make better estimates on how much ice will melt and be lost. The Arctic has been losing ice every year as the ice slowly starts to melt away, however it has not always been able to be forecasted to know how much ice will be lost. Each year the sea ice starts to melt in the spring following wintertime, scientists still struggle to estimate exactly how much ice they expect will disappear through the melt season. NASA's forecasting satellite model will allow researchers to make precise estimates.

NASA's new satellite forecasting model is a huge improvement allowing measurements for researchers to a lot more accurate on how much ice will melt and be lost. The science community has done measurements on physical characteristics, however there were problems with this method that was not accurate enough. This new technology will allow scientists correlate the measurement to was is causing the lose of ice, and will purpose new ways on how to slow it down.
