Seismic signals allow researchers to see under river ice

River scientists from Sweden, Finland and Germany report detailed measurements of sediment movement and water level in an ice-covered river using a novel technique—seismic signals. The results are published in the Journal ...

Alaskan seismometers record the northern lights

Aaron Lojewski, who leads aurora sightseeing tours in Alaska, was lucky enough to photograph a "eruption" of brilliant pink light in the night skies one night in February.

How seismometers record church bells ringing

A new study made by Jordi Díaz, researcher at Institute of Earth Sciences Jaume Almera of the Spanish National Research Council (ICTJA-CSIC), has compared the different types of bell ringing to indicate the passage of time ...

A year of surprising science from NASA's InSight Mars mission

A new understanding of Mars is beginning to emerge, thanks to the first year of NASA's InSight lander mission. Findings described in a set of six papers published today reveal a planet alive with quakes, dust devils and strange ...

Machine learning-detected signal predicts time to earthquake

Machine-learning research published in two related papers today in Nature Geoscience reports the detection of seismic signals accurately predicting the Cascadia fault's slow slippage, a type of failure observed to precede ...
