Researchers hit the jackpot in late March, when, for the first time, they began recording data on lightning in a volcanic eruption--right from the start of the eruption. Using a multi-station, ...

For the first time, scientists have been able to “see” and trace lightning inside a plume of ash spewing from an actively erupting volcano. When Alaska's Mount Redoubt volcano began rumbling back to ...

An animation of cloud-to-cloud lightning (the circles) as detected by the Lightning Mapping Array (LMA) over the Telescope Array Surface Detectors (red squares). The color represents time -- earliest ...

The Telescope Array detected 10 bursts of downward terrestrial gamma-ray flashes (TGFs) between 2014 and 2016, more events than have been observed in rest of the world combined. They are the first to ...

For years, research has been done to develop better ways of forecasting and identifying potentially tornadic storms, in an effort to increase lead times on warnings. In this context, lead time refers ...

An unassuming-looking rod on a rooftop in Beltsville, Md., connected with wires to specialized computer equipment in the building below, is helping scientists pinpoint the location of lightning as it ...
