The massive eruption
from the underwater Tonga volcano in the Pacific earlier this year generated a blast so powerful
It sent massive
pressure waves rippling through the atmosphere and around the globe.
These waves were
the fastest ever observed within Earth's atmosphere, reaching speeds of 720 miles (1,158 kilometers) per hour
Hunga volcano lies about
40 miles northwest of the Tongan capital of Nuku'alofa and sits within a line of volcanoes called Tonga-Kermadec volcanic arc.
On Jan. 15, Hunga
erupted and sent a towering plume of gas and particles billowing into the mesosphere
The plume reached
36 miles (58 km) tall at its highest point, making it the largest volcanic plume(opens in new tab) in the satellite record.
