Giant Tonga Volcanic Eruption Was as Powerful as Krakatau in 1883, Scientists Reveal

An underwater volcano erupted in January near the Pacific nation of Tonga and sent massive pressure waves racing through Earth’s atmosphere, where they lapped the planet several times. The last volcano to generate such large ripples in the atmosphere was Krakatau in 1883, during one of the most destructive volcanic eruptions in recorded history, a … Read more

Crescent-shaped bow shock waves and numerous lighting strikes are also visible. Credit: NASA Earth Observatory image by Joshua Stevens using GOES imagery courtesy of NOAA … Read more

Tonga Eruption | The UCSB Current

On January 15, the volcano Hunga Tonga-Hunga Ha’apai devastated the nation of Tonga. The eruption triggered tsunamis as far afield as the Caribbean and generated atmospheric waves that traveled around the globe several times. Meanwhile, the volcano’s plume shot gas and ash through the stratosphere into the lower mesosphere. Just two months after the eruption, … Read more

Giant Ice Volcanos on Pluto May Have Formed From Multiple Cryovolcanic Eruption Events

New Horizons mission scientists have determined that cryovolcanic activity most likely created unique structures on Pluto not yet seen anywhere else in the solar system. The amount of material required to create the formations suggest its interior structure retained heat at some point in its history, enabling water-ice-rich materials to build up and resurface the … Read more

Volcano Watch: Remembering the 2011 Kamoamoa eruption

The 35-year-long Pu’u’o’o eruption on the middle East Rift Zone of Kilauea was a remarkable opportunity for scientists to improve volcano research and monitoring. Even short-lived episodes in this eruption, like the four-day-long Kamoamoa eruption, offered important insights. For the 11th anniversary of the Kamoamoa eruption, this week’s “Volcano Watch” highlights the episode and some … Read more

How a major volcanic eruption paved the way for the rise of the dinosaurs – BIOENGINEER.ORG

The supercontinent divide — Unravelling an incident of a bygone age The supercontinent Pangaea, which was a combination of today’s continents, broke apart at the end of the Triassic period due to large-scale volcanic activity. This volcanic activity was thought to be the most likely cause of the fourth mass extinction, but studies were inconclusive … Read more
