Original Message InSAR is a remote sensing method that employs a laser to concentrate a beam of radiation on a target, bouncing back to a sensor on an antenna, providing a comprehensive map of a region.

One of the most concerning sites in InSAR was near Mammoth Lakes, a hamlet in the Sierra Nevada highlands.

"Right here in the center, you see there's a resurgent dome," Mr. Peacock said, pointing to a map made from the data.

A blazing-hot red spot is depicted just beneath the Earth, indicating the presence of magma.

"Something beneath it is pulling it higher," Mr. Peacock continued.



Studying Volcanic Activities

Mr. Peacock and Mr. Nelson set up a pair of sensor pipes immediately above the site. The InSAR data revealed the resurgent dome and checked for signals of problems deep below to see if the Long Valley Caldera was coming back to life.

The pipes assisted the two scientists in detecting changes in the Earth's magnetic field, allowing them to establish whether any liquid existed underneath.

They observed enormous volumes of liquid beneath the domes' surface during the experiments, indicating volcanic activity.
