West Texas oil patch heaving and sinking at alarming rates

Geophysicists from the Southern Methodist University in Dallas found that decades of oil production activity in Texas have destabilized localities of an area about 10 000 km2 (4 000 mi2) populated by small towns, roadways and a vast network of oil and gas pipelines...

Major flooding cyclical rather than random, new research says

University of Newcastle's (UON) fresh research found further evidence to support the notion that severe flooding events occur cyclically, challenging the widely approved assumption that floods occur randomly. The study is now raising questions about the...

Evidence of one of the largest floods in Earth’s history in the central Mediterranean

An international team of scientists has uncovered evidence of one of the largest floods in Earth's history in the central Mediterranean seafloor. The flood, known as the Zanclean flood, is thought to have ended the Messinian Salinity Crisis (MSC), a period...

Research helps explain ongoing changes in geomagnetic field

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...

How cosmic rays produce clouds and influence Earth's climate

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...

New timelapse of Hunga Tonga-Hunga Ha'apai volcanic island forming

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...

Mapping areas at risk from liquefaction

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...

Earth’s vibrational "hum" - frequencies at which our planet naturally vibrates measured

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...

Unearthing the underground effects of earthquakes and volcanoes

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....

Two Super-Earths around red dwarf K2-18

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...

Astronomer's map reveals location of mysterious fast-moving gas

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 in Himalaya bigger because tectonic plates collide faster

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...

The most tightly coupled pair of supermassive black holes ever seen

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...

Southern Ocean drives massive bloom of tiny phytoplankton

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...

Mass of warm rock is rising beneath New England

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...
