In January 2022, one of the most powerful volcanic eruptions in recorded history rocked the South Pacific islands of Tonga, sending shockwaves around the world.

NOVA: Hidden Volcano Abyss lets viewers experience the terrifying power of the eruption and the devastating tsunami that struck the shores of Tonga through first-person accounts.

The eruption could be heard nearly 6,000 miles away in Alaska and, from space, scientists could see huge clouds of ash and an atmospheric shockwave that radiated from the eruption site at nearly the speed of sound.

NOVA asks the question: Why was this eruption so big? How did it cause the tsunami? And could another disaster loom?
