Lightning Discharge Type Linked to Terrestrial Gamma‐Ray Flashes
For the first time, the connection between energetic in cloud pulse and terrestrial gamma‐ray flashes is confirmed in the Gamma-Ray Observation of Winter Thunderclouds experiment in Japan.
The First Undeniable Climate Change Deaths
In 2018 in Japan, more than 1,000 people died during an unprecedented heat wave. In 2019, scientists proved it would have been impossible without global warming.
Real-time Ground Motion Estimation for Large Earthquakes
Advanced computing technology can be used to forecast ground shaking from earthquakes and provide an early warning in real time.
Submarine Canyons Breed Megawaves in Japan
The canyons act like a prism, focusing waves into mammoths of destruction.
Tiny Fireballs May One Day Reveal Unseen Asteroids
The tiny fireball that flew over Japan in 2017 came from an asteroid that could threaten Earth in 10 million years or so. Scientists are trying to use these little meteors to hunt larger objects.
Japan Puts Its Mark on Geologic Time with the Chibanian Age
The newly named period in the Pleistocene identifies a key moment in geological history: the last time Earth’s magnetic poles switched places.
Microphysics and Positive Lightning in Hokuriku Winter Clouds
The microphysics of the frequent, and frequently positive, lightning of Hokuriku winter clouds was investigated by systematic, in situ observation of individual precipitation particle type and charge.
How Land Use Affects Nutrient Pollution in a Changing Climate
As heavy rain falls more frequently, the land alongside a river has a greater effect on the waterway’s nutrient levels—for better or worse.
Groundwater Drawn Downward After Kumamoto Quake
A unique set of high-frequency groundwater level monitoring reveals a loss of approximately ten million cubic meters of groundwater after a major earthquake.
