Scientists from the University of Rochester used new data from sites in southern Africa to help explain recent and ongoing changes in Earth's magnetic field, best expressed by a deepening area of low field called the South Atlantic Anomaly. Their research...

A new study published in Nature Communications this week reveals how atmospheric ions, produced by the energetic cosmic rays raining down through the atmosphere, helps the growth and formation of cloud condensation nuclei - the seeds necessary for forming clouds in...

In December 2014 and early 2015, Hunga Tonga-Hunga Haʻapai undersea volcano near Tonga's capital Nuku'alofa erupted, sending a violent stream of steam, ash and rock into the air. When the ash finally settled in January 2015, a newborn island with a 120 m...

A team of researchers has joined forces to investigate and find solutions to tackle one of the most devastating forms of seismic phenomena - liquefaction. Liquefaction occurs in loosely-compacted sandy soils which are fully saturated with water. Seismic vibrations...

Scientists have long known earthquakes can cause the Earth to vibrate for extended periods of time. However, in 1998 a research team found the Earth also constantly generates a low-frequency vibrational signal in the absence of earthquakes. Since then, seismologists...

Japanese researchers find predictive potential in underground changes associated with 2016 Kumamoto earthquake and subsequent volcanic eruptions. Most of what we know about earthquakes and volcanoes is based on what we can observe at the Earth's surface....

New research using data collected by the European Southern Observatory (ESO) has revealed that a little-known exoplanet called K2-18b could well be a scaled-up version of Earth. Just as exciting, the same researchers also discovered for the first time that the...

An Australian scientist has created the most detailed map ever of clouds of high-velocity gas in the Universe around us. The map covers the entire sky and shows curious clouds of neutral hydrogen gas that are moving at a different speed to the normal rotation of the...

Earthquakes that happen in densely populated mountainous regions, such as the Himalaya, spell bigger earthquakes because of a fast tectonic-plate collision, according to a new study in Earth and Planetary Science Letters. Researchers from Geophysical Fluid Dynamics...

Researchers at the Institute of Photonic Sciences made the first demonstration of an elementary link of a hybrid quantum information network, using a cold atomic cloud and a doped crystal as quantum nodes and single photons as information carriers. In a recent...

An intriguing source has been discovered in the nearby Andromeda galaxy using data from NASA's Chandra X-ray Observatory and ground-based optical telescopes. Previously thought to be part of the Milky Way's neighbor galaxy, the new research shows this source...

Why does the floor of calderas lift disproportionately without erupting? Researchers from UNIGE and Roma Tre used thermal and experimental models to explain one of the least-understood processes in volcanology: 'Caldera resurgence' A spectacular proof of our...

Scientists have uncovered the ocean conditions that support a massive summertime bloom of algae that spans 16 % of the global ocean. Known as the Great Calcite Belt, this dense group of a microscopic phytoplankton, coccolithophores, can be seen in satellite images...

Slowly but steadily, an enormous mass of warm rock is rising beneath part of New England, although a major volcanic eruption isn't likely for millions of years, a Rutgers University-led study suggests. The research is groundbreaking in its scope and challenges...

Study by Beatrice Magnani, USGS and other SMU scientists shows recent seismicity in Fort Worth Basin occurred on faults not active for 300 million years. The study indicates reactivation of long-dormant faults as a consequence of waste fluid injection. Recent...

Although magnitude 6 earthquakes occur about every 25 years along the Parkfield Segment of the San Andreas Fault, geophysical data suggest that the seismic slip induced by those magnitude 6 earthquakes alone does not match the long-term slip rates on this part of...

Volcanic eruptions always seize the attention of climate scientists, because the sulfate aerosols formed in the volcanic plumes may stay months to years in the stratosphere - the second layer of the Earth's atmosphere - resulting in the increase of radiation...
