Strong storms can generate earthquake-like seismic activity
WASHINGTON–Researchers have discovered a new geophysical phenomenon where a hurricane or other strong storm can produce vibrations in the nearby ocean floor as strong as a magnitude 3.5 earthquake. “We’re calling them ‘stormquakes,’” said Wenyuan Fan, an assistant professor of…
Mathematicians find gold in data
Russian mathematicians and geophysicists have made a standard technique for ore prospecting several times more effective. Their findings are reported in Geophysical Journal International , one of the most respected scientific periodicals on computational geophysics. The controlled-source electromagnetic method, known…

New science on cracking leads to self-healing materials
Cracks in the desert floor appear random to the untrained eye, even beautifully so, but the mathematics governing patterns of dried clay turn out to be predictable–and useful in designing advanced materials. In a pair of new studies from Princeton…
Rice irrigation worsened landslides in deadliest earthquake of 2018 finds NTU study
Irrigation significantly exacerbated the earthquake-triggered landslides in Palu, on the Indonesian island of Sulawesi, in 2018, according to an international study led by Nanyang Technological University, Singapore (NTU Singapore) scientists. The 7.5 magnitude earthquake struck the Indonesian city on 28…

The pressure to take action is enormous
Bremerhaven/Germany, 25 September 2019. Today, in Monaco, the IPCC will present its new Special Report on the ocean and the Earth’s frozen regions. The report summarises observations of and projections on climate-based changes to ecosystems in the ocean, coastal, polar…
‘Treasure trove’ of quake clues could be unearthed by wavy new technique
Their technique combines traditional ‘acoustic mapping’ with a newer method called ‘full waveform inversion’. They found their new method enhanced their view of rocks along a fault line – a break in the Earth’s crust – off the east coast…
Why are mountains so high?
Over millions of years, Earth’s summits and valleys have moved and shifted, resulting in the dramatic landscapes of peaks and shadows we know today. Mountains often form when pressure under Earth’s surface pushes upward, yet many factors impact their ultimate…
