ROME (AP) — Mount Etna in Sicily has roared back into spectacular volcanic action, sending up plumes of ash and spewing lava.

Italy’s National Institute of Geophysics and Vulcanology (INGV) says that the volcano, which initially “re-awoke” in late July, sprang into fuller action Thursday evening by shooting up chunks of flaming lava as high as 150 meters (500 feet) almost constantly.

On Friday, INGV said the action was continuing, feeding ash plumes several hundred meters (yards) into the air above the crater.

Researchers have demonstrated that they can discern individual letters on a display based only on the ultrasonic whine it emits.
