Earth sound when hit by solar storm

'Eerie' sound Earth makes when hit by solar storm recorded for the first time

Data from the European Space Agency's (ESA) Cluster mission has provided a recording of the 'eerily disturbing' sound the Earth makes when it is hit by a solar storm. The song comes from waves produced in the Earth's magnetic field by the collision...

massive tsunami hit oman 1000 years ago

Massive tsunami as high as 15 m (49 feet) hit Oman 1 000 years ago, research finds

Researchers from the universities of Bonn, Jena, Freiburg, and RWTH Aachen found evidence that a massive tsunami, with waves as high as 15 m (49 feet) hit Oman a thousand years ago. It is unclear to what extent the Arabian and Eurasian plates get stuck. It is...

maritime continent weakens asian monsoon through au cefs

Maritime Continent weakens Asian tropical monsoon rain through Australian cross-equatorial flows

A new study reveals how the Maritime Continent weakens tropical monsoon rainfall in Asia through cross-equatorial flows (CEF) in Australia. The CEFs in the lower atmosphere has a significant role in the transport between mass, moisture, and energy between the...

changes in the ocean atmosphere system south pacific

Changes in South Pacific high-altitude winds have significant effects on the Antarctic Circumpolar Current's intensity and position

A recently published study showed findings that in the past million years, the high-altitude winds of the southern westerly wind belt - which spans nearly half the Earth - did not behave as uniformly over the Southern Pacific, as initially assumed. The researchers...

Research uncovers the secret of explosive volcanism

Researchers reporting in Nature Communications suggest they've unlocked the secret of explosive volcanism. The team studied samples at Indonesia's Mount Merapi, concluding that explosivity of stratovolcanoes rises when mineral-rich gases seal the pores and...

caldera discovery 2019 f

Researchers discovered what could be the largest caldera on Earth

A team of researchers including members from GNS Science, led by marine geophysicist Jenny Anne Barretto, have identified an ancient mega-volcano with what could be the largest known caldera on Earth. The feature is on the crest of Benham Rise, an oceanic plateau...

cascadia earthquake model

3D models of Cascadia megathrust events match coastal changes from 1700 earthquake

Researchers were able to get a better idea of what kind of megathrust seismic activity was behind the 1700 Cascadia earthquake by combining models of Magnitude 9 to 9.2 earthquakes on the Cascadia Subduction Zone with geological evidence of past coastal changes....

Forecasting earthquakes 5 days ahead, research

An international team of scientists reporting in Doklady Earth Sciences discovered that with an impending earthquake, the parameters of internal gravity waves (IGWs) can change several days before the seismic event. IGW is the fluctuation of air masses, which, in...
