New research published in Nature this month determined that an intense earthquake swarm at the Bransfield Strait, Antarctica was caused by the rapid transfer of magma from the Earth’s mantle near the crust-mantle boundary to almost the surface.
A new study published this week in Science Advances presents geoarchaeological evidence revealing a major M~9.5 tsunamigenic earthquake that severely affected prehistoric hunter-gatherer-fisher communities some 3 800 years ago, causing an exceptional social disruption reflected in contemporary changes in archaeological sites and triggering resilient strategies along these coasts. Together with tsunami modeling results, researchers suggest…
New research led by the National Oceanography Centre (NOC) and ICARUS presented seasonal to decadal variations in Northern Hemisphere jet stream latitude and speed over land (Eurasia, North America) and oceanic (North Atlantic, North Pacific) regions for the period…
Scientists have uncovered the source of a mysterious 2021 tsunami that sent waves around the globe in August 2021 when a magnitude 7.5 earthquake hit near the South Sandwich Islands. The epicenter was 47 km (29 miles) below the Earth’s surface — too deep…
A team of researchers from Canada and Germany discovered and documented a new type of earthquake in an injection environment in British Columbia, Canada. The recently discovered seismic events are slower than conventional earthquakes. Their existence supports a…
An international team of geologists believes they have identified a sunken continent hidden under Iceland and the surrounding ocean, which they called Icelandia. The scientists said the continent could stretch from Greenland all the way to Europe. If proven, this…
A research article published by AGU on June 7, 2021, shows that unrest registered under New Zealand's Taupo supervolcano in 2019 was volcanic in nature and origin, demonstrating that it's still an active and potentially hazardous volcano that needs to be…
Scientists have released new observations of solar activities, such as Coronal Mass Ejections (CMEs) and cosmic rays, gathered by the Global Muon Detector Network (GMDN) at the Syowa Station in the Antarctic. The team found that high-speed solar wind causes the…
A study by NASA astronomer Sten Odenwald found that magnetometers in smartphones can detect small disturbances of the Earth's magnetic field, allowing such devices to be used to form a distributed space weather observatory. The 3-axis Hall-effect magnetometer…
Researchers have confirmed the presence of magnetic plasma waves in the Sun's photosphere, catching them in action. Known as Alfven Waves, these fascinating waves were first predicted in 1947. The Alfven Waves, named after Nobel Prize-winning scientist Hannes…
