A magnitude 4.8 earthquake has shaken Yellowstone National Park and rattled observers of one of the world’s deadliest super volcanoes.
The quake ”” the most powerful in 30 years ”” struck near the Wyoming border with Montana yesterday, almost in the center of the United States’ most famous national park.
Late last year a new study into the enormous super volcano found the underground magma chamber to be 2.5 times larger than previously thought ”” a cavern spanning some 90km by 30km and capable of holding 300 billion cubic kilometres of molten rock.
If the sleeping giant were to wake, the outflow of lava, ash and smoke would devastate the United States and affect the entire world.
