Earthquake depth impacts potential tsunami threat

Earthquakes of similar magnitude can cause tsunamis of greatly varying sizes. This commonly observed, but not well-understood phenomenon has hindered reliable warnings of local tsunamis. This research provides new insight that connects the characteristics of earthquakes -- magnitude, depth where two tectonic plates slip past each other and the rigidity of the plates involved -- with the potential...

Juno spacecraft 'hears' Jupiter's moon

Sounds from a Ganymede flyby, magnetic fields, and remarkable comparisons between Jupiter and Earth's oceans and atmospheres were discussed during a briefing today on NASA's Juno mission to Jupiter at the American Geophysical Union Fall Meeting in New Orleans.

Using sparse data to predict lab quakes

A machine-learning approach developed for sparse data reliably predicts fault slip in laboratory earthquakes and could be key to predicting fault slip and potentially earthquakes in the field. The research by a Los Alamos National Laboratory team builds on their previous success using data-driven approaches that worked for slow-slip events in earth but came up short on large-scale stick-slip...

12 dead as powerful typhoon batters the Philippines

At least 12 people have died in the strongest typhoon to hit the Philippines this year, the disaster agency said Friday, after the storm swept across the archipelago uprooting trees, toppling power poles and flooding villages.

Harvard drops standardized test requirement through 2026

Students will be able to apply to Harvard University without submitting SAT or ACT scores for at least the next four years, the Ivy League school announced Thursday, extending a policy many colleges have adopted during the pandemic and that a growing number are keeping for years to come.

Margaret Waddy obituary

My aunt Margaret Waddy, who has died aged 77 of a pulmonary embolism, was a horticulturist and a teacher, a quiz fan and a committed volunteer with Samaritans in Cambridge.Margaret was born in London but her early life was spent in the Gold Coast, now Ghana, where her parents, Bernard (known as BB) Waddy, a doctor in tropical medicine, and Mary (nee Lawrence), worked for the Colonial Service. At...

Using drones to capture coastal heritage before it's lost

Improved understanding is a necessary first step in the process of managing the loss of an archaeological site, and the Seaford Head Project is trialing ways of achieving this including 3D modeling and surveying the site with drones. The project will also trial the use of podcasts and videos to engage local communities in a conversation about coastal change and how they feel about the eventual,...

Unraveling a puzzle to speed the development of fusion energy

Researchers at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory have developed an effective computational method to simulate the crazy-quilt movement of free electrons during experimental efforts to harness on Earth the fusion power that drives the sun and stars. The method cracks a complex equation that can enable improved control of the random and fast-moving moving...
