Ridgecrest earthquakes increase chance of San Andreas tremors

In a new study, scientists have warned that the Ridgecrest earthquakes in Southern California in 2019 could increase the chance of a San Andreas Fault earthquake. The probability is higher because the 2019 temblors stressed the Garlock Fault, which links the...

Study finds correlation between solar activity and large earthquakes worldwide

A new study published in the Nature Scientific Reports on July 13 suggests that powerful eruptions on the Sun can trigger large earthquakes on Earth. In the paper, the authors analyzed 20 years of proton density and velocity data, as recorded by the SOHO satellite,...

Big glaciers repeatedly present in major mountain areas along the Mediterranean during Pleistocene era

A new study found that big glaciers were repeatedly present in most of the major mountain areas along the Mediterranean-- from Morocco in the west, to the Black Sea coast of Turkey in the east-- during the Pleistocene era, or the first epoch of the Quaternary period...

Scientists measure structure of enormous solar flare

Astronomers at the Harvard-Smithsonian Center for Astrophysics reported spatially-resolved observations of the regions of the Sun's magnetic field and flare-ejected electron activity, with the results suggesting that these kinds of spatial structures in the...

Seismologists find slow earthquakes in Cascadia predictable

Seismologists at Caltech analyzed 10 years' worth of slow-slip events that result from episodic fault slip, like regular earthquakes, but only produce barely perceptible quakes in the Cascadia region of the Pacific Northwest. They found that this particular type...

New study explains how volcanoes explode in the deep sea

Most volcanic eruptions occur at the bottom of the oceans, and modern oceanography has shown that submarine volcanism not only deposits lava but also emits large amounts of volcanic ash. For the first time, an international research group explained the mechanisms...

NASA's DART mission may cause first ever man-made meteor shower

The impact of NASA's Double Asteroid Redirection Test (DART) mission-- which aims to nudge the orbit of its target for planetary defense purposes-- may produce the first meteor shower from human activities in space, according to research published in The...

New study shows Earth's magnetic field can change 10x faster than currently believed

A new study published in Nature Communications shows that previous changes in the direction of Earth's magnetic field reached rates that are up to 10 times larger than the fastest currently reported variations of up to one degree per year. The authors combined...

ESO telescope catches the disappearance of massive unstable star

Astronomers have discovered the absence of a massive unstable star in the Kinman Dwarf galaxy using ESO's Very Large Telescope (VLT). One explanation offered is the end of a luminous blue variable (LBV) eruption of a surviving star, with a mild drop in...

Massive eruption at Alaska's Okmok volcano in 43 B.C.E. linked with cold weather, widespread famine, strange sighting in the sky and the fall of Roman Republic

A new study suggests that the massive Okmok volcano eruption in Alaska in 43 B.C.E. may have caused a nearly two-decade power struggle that led to the fall of the Roman Republic and the rise of the Roman Empire. According to records, the period was marked with...

Study reveals how water in the deep Earth triggers seismic events

In a new study, an international team of scientists provided the first conclusive evidence directly correlating deep Earth's water cycles, magmatic productivity, and earthquake activity. Water and other volatiles that are cycled through the deep Earth have...

Motions in the Sun unveil inner workings of sunspot cycles

The Sun's magnetic activity fluctuates in a rhythm of about 11 years, which is reflected in the frequency of sunspots. During solar maximum, huge sunspots and active regions appear on the surface of the star. Scientists have long been puzzled over the reason...

Massive volcanic eruption in Japan as the cause of severe famine in Europe in 1108

The eruption in Japan's Asamayama volcano in the year 1108 may have led to an extreme weather event that triggered severe famine in Europe, new research revealed. The study is based in part on the research team's analysis of ice cores extracted from glaciers...
