A new study has found that massive volcanic eruptions that took place over the past 70,000 years in Nicaragua could have injected enough gases into the atmosphere to temporarily thin the ozone layer. The study also concluded that if such an event took pace today, the amount of gases released could equal twice the […]

Mount Tambora, the volcano that caused the most deaths in known history (71,000) may explode again soon…
The volcanic island of Guadalupe, seen below peeking through the clouds near the top of this image taken by the European Space Agency’s satellite Envisat, is the cause for the beautiful swirls in the clouds.
Hello Planetsavers! I thought I’d start doing a monthly wrap-up of our top 20 posts for people to have a glance at. Many of the top stories this month, as you’ll notice, were clearly tied into major world news events. Google is the main traffic driver for the large majority of sites on the Internet and ours isn’t an exception. Covering environmental news consistently, this often results in the biggest news stories rising to the top.
The Russian volcano Bezymianny erupted on the morning of April 14, this year. The images below were taken over a week later on the 22nd, and shows the extend of the eruption by the the Advanced Land Imager (ALI) aboard the Earth Observing-1 (EO-1) satellite.
astrologer has also predicted that such a close perigee would/must somehow perturb the earth’s (tectonic) integrity so much that it will trigger major earthquakes and even volcanoes (not simply severe storms). Although he is not clear on the exact lunar-geo-mechanisms that would produce these quakes, never-the-less this lunar-induced disaster scenario quickly set the Web abuzz with yet another wave of doom-and-gloom “apocalypticism.”
Timing is everything.
Hawaii’s Kīlauea volcano, one of the most active and dangerous volcanoes in the world (and also the most visited volcano in the world), began erupting violently yesterday after a nearby crater collapsed on Saturday. Enjoy the videos above and below capturing this, via the AP and Reuters/Guardian, respectively. “Hawaii Volcano Observatory scientists said the floor of […]
The scientists used a general circulation model known as ModelE (developed at NASA’s Goddard Institute for Space Studies, New York). The model calculates ocean-atmosphere coupling effects in addition to allowing varying aerosol inputs.
The initial input for the simulation was 5 teragrams (megatons) of black carbon particles injected into Earth’s upper troposphere. This is the estimated result of the surface detonation of 100 Hiroshima-size bombs (each equivalent to 15K tons of TNT).
