The melting of the glacial ice sheets in North America, Europe and elsewhere was a stochastic process.Long periods of slow melting alternated with bursts of accelerated melting. Between the Late Glacial Maximum and the early Holocene, global sea level rose by 100 to 130
Mount St. Helens reawakened in late September 2004. Small magnitude earthquakes beneath the 1980-1986 lava dome increased in frequency and size, and a growing welt formed on the southeast margin of the previous lava dome and nearby portions of Crater Glacier.On October
On July 23, 2012, a massive cloud of solar material erupted off the sun's right side, zooming out into space. It soon passed one of NASA's Solar Terrestrial Relations Observatory, or STEREO, spacecraft, which clocked the CME as traveling between 2 900 – 3…
One of the biggest unknown volcanic eruptions" in the last 500 years has been given new light through the collaboration of Bristol University colleagues from the School of Earth Sciences, PhD student Alvaro Guevara-Murua, and Dr. Caroline Williams, from the Departm
Hurricane "Hugo" (1989) was a classic Cape Verde-type hurricane first detected as a tropical wave emerging from the coast of Africa on September 9, 1989. Moving steadily westward, the system became a tropical depression the next day, a tropical storm on the 11
Dwardu Cardona showed that a reconstruction of Earth’s cosmic history can be distilled from the universal “mytho-historical record,” complemented by studies in earth history and space science. Most recently, the strongest scientific validation comes fr
A new research from Curtin University has shown that ancient volcanic eruptions in Australia some 510 million years ago significantly affected the climate, causing the first known mass extinction in the history of complex life.Associate Professo
On March 29, 2014 the sun released an X-class flare. It was observed by NASA's Interface Region Imaging Spectrograph, or IRIS; NASA's Solar Dynamics Observatory, or SDO; NASA's Reuven Ramaty High Energy Solar Spectroscopic Imager, or RHESSI; the Japanese Aer
On July 23, 2012, an intense solar storm narrowly missed Earth. The CME reached the speed of almost 3000 km/s, which is more than 4 times faster than a typical eruption. It was not Earth directed, but it did hit STEREO A spacecraft and researchers have been analyzi
In April of 1815 Indonesian Mount Tambora produced the largest and deadliest volcanic eruption on our planet in the known history. A giant plinian eruption column is estimated to have reached about 40 – 50 km altitude.The volcano unleashed from 50 – 150 cubic k
