Margaret Mangan didn't sleep well in the weeks following the Ridgecrest, Calif., earthquakes. The July shaking triggered a swarm of smaller tremors in the... more
Distributed fiber-optic sensing technology coupled to existing subsea cables (dark fiber) allows observation of ocean and solid earth phenomena. We used an optical fiber... more
Fiber-optic cables that constitute a global undersea telecommunications network could one day help scientists study offshore earthquakes and the geologic structures hidden deep beneath the ocean surface. more
The deadly volcanic eruption of Anak Krakatoa in 2018 unleashed a wave at least 100m high that could have caused widespread devastation had it been travelling... more
New Guinea is the most biologically and linguistically diverse tropical island on Earth, yet the potential impacts of climate change on its biocultural heritage remain unknown. Analyzing 2353 endemic plant species distributions, we find... more
When Timothée Boitouzet studied architecture in Japan, where buildings need to survive earthquakes, he realised the next smart material might be one that humans have used for thousands of years—wood. more
When -- and how -- Earth's surface evolved from a hot, primordial mush into a rocky planet continually resurfaced by plate tectonics remain some of the biggest unanswered questions in... more
Russian and Italian scientists have recently come closer to understanding volcanic eruptions by studying Monte Nuovo near Naples as a basis. Lava, the molten rock that forms and then solidifies on the Earth's surface,... more
