World’s largest earthquake early warning system announced in China

China’s Earthquake Early Warning System (EEWS), the largest of its kind globally, has been completed, according to an announcement by Min Yiren, the head of the China Earthquake Administration (CEA), on June 8, 2023. The system is anticipated to be fully functional by the end of the year, covering more than 15 000 monitoring stations, three national centers, 31 provincial centers, and 173 prefectural and municipal information release centers.

Breakthrough computer model to provide better space weather forecasts

Breakthrough computer model to provide better space weather forecasts

NOAA’s National Weather Service (NWS) has transitioned a new computer model into operations to increase its understanding of space weather events and improve space weather forecasting capabilities. These advances will help forecasters provide better…

Using smartphones to create distributed space weather observatory

Using smartphones to create distributed space weather observatory

A study by NASA astronomer Sten Odenwald found that magnetometers in smartphones can detect small disturbances of the Earth's magnetic field, allowing such devices to be used to form a distributed space weather observatory. The 3-axis Hall-effect magnetometer…

DeepShake spatiotemporal neural network improves early earthquake warnings

DeepShake, a spatiotemporal neural network trained on more than 36 000 earthquakes, provides a new way of forecasting ground shaking intensity prior to an earthquake, researchers reported at the Seismological Society of America's 2021 Annual Meeting. The…

Lasers detect space debris in daylight for the first time

Lasers detect space debris in daylight for the first time

For the first time, scientists have used lasers to detect space debris in broad daylight. Prior to this, lasers could only be used to measure the distance to space debris during a few twilights hours. A new study proved that it is possible to use lasers in full…
