An international study published this week in Nature Geoscience argues that explosive extratropical volcanic eruptions, those taking place in mid and high latitudes, have a much stronger influence on climate than was previously assumed. In recent decades,…
GFZ Potsdam scientists analyzed a large transient strainmeter signal recorded along the southern shore of the eastern Sea of Marmara region in northwestern Turkey after M4.4 earthquake. The strain signal lasted about 50 days, indicating deep crustal movement near…
A team of scientists has, for the first time, used a single, cohesive computer model to simulate the entire life cycle of a solar flare: from the buildup of energy thousands of kilometers below the solar surface, to the emergence of tangled magnetic field lines, to…
Meteorologist Dr. Harold Brooks appeared on AMHQ recently, speaking about Tornado Alley and his recent study about spatial trends in United States tornado frequency. While it's evident that tornadoes are shifting east, the reasons why this is happening are still…
Rice University geophysicists have determined Earth shifted relative to its spin axis within the past 12 million years, which caused Greenland to move far enough toward the north pole to kick off the ice age that began about 3.2 million years ago. The study is based…
An international team of scientists announced a remarkable discovery of one of the youngest large asteroid impact craters on Earth. The crater is buried under 1 km (0.62 miles) of ice in a remote area of northwest Greenland. The finding was published in the November…
Japanese researchers have taken the first steps to understand how the Sun's rotational cycle influences lightning activity on Earth. The answers were found in diaries dating back to the 1700s. "It is well known that long-term – centennial to…
A study published recently in Scientific Reports presets geodetic evidence for interconnectivity between Aira and Kirishima magmatic systems in Japan. This is the first study to confirm that radical changes of one volcano in southern Japan were the direct result of…
A new study published recently in Science offers an explanation for a mysterious and sometimes deadly weather pattern in which the jet stream stalls out over a region. The discovery is expected to help predict long-term patterns, including which areas may see more…
Gravitational tugs from Jupiter and Venus slightly elongate Earth's orbit every 405 000 years, an amazingly consistent pattern that has influenced our planet's climate for at least 215 million years. This pattern allows scientists to more precisely date…
