Researchers define a new ocean-life zone, name it the Rariphotic

Smithsonian scientists have recently defined a new ocean-life zone, comprising of reef fishes, including numerous new species, that live well below shallow coral reefs. The new zone was named Rariphotic. The new zone was defined based on the unique fish fauna...

REEF - A new measure of earthquake ruptures

A team of seismologists has developed a new measurement of seismic energy release that can be applied to large earthquakes. Called the Radiated Energy Enhancement Factor (REEF), it provides a measure of earthquake rupture complexity that better captures variations...

World's first 3D thermal image of volcano

Scientists from the University of Aberdeen have created the world's first 3D thermal image of an active volcano. The spectacular 3D image of Stromboli in Italy was made using high-precision cameras which are mounted to an aerial drone. The team of geoscientists...

US East Coast experienced 90% increase in flooding in the past 20 years

The University of New Hampshire scientists found that high tide floods, or so-called 'nuisance flooding,' that happen along shore roadways during seasonal high tides or minor wind events along the US East Coast are occurring far more frequently than ever...

Ireland's recent decade found to be the wettest in over 300 years

With a 10-year average rainfall of almost 1 990 mm (78.3 inches) per year, the decade from 2006 to 2015 was Ireland’s wettest on record. This compares with a long-term 300-year decadal average of 1 080 mm (42.5 inches) per year, and 940 mm (37 inches), the...

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...

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....
