Deep recurring earthquakes detected beneath dormant Mauna Kea volcano, Hawaii

USGS seismologists have detected deep long-period earthquakes beneath the dormant Mauna Kea volcano in Hawaii at depths of about 20 to 25 km (12 to 15 miles) occurring with surprising regularity every 7 to 12 minutes. While low-frequency earthquakes are not unusual,...

New Australasian model can forecast tropical cyclones four months ahead

Tropical cyclones in the Pacific can now be forecast up to four months ahead of the season with a new model developed by scientists from New Zealand and Australia. According to Dr. Andrew Magee from the center for water, climate, and land at the University of...

Study reveals South Atlantic magnetic anomaly is a recurring feature

In a new study, scientists from the University of Liverpool in England traced back the strange behavior of the magnetic field in the South Atlantic region and found that similar anomalies existed as far back as 8 to 11 million years ago. The South Atlantic Anomaly...

New fault system discovered in southeastern Nepal

An international team has found a new fault system in southeastern Nepal, with the potential to cause earthquakes in a densely populated area. The faults show that the front of the tectonic movement in the mountain belt is 40 km (25 miles) farther south than...

Researchers develop equations for earthquake forecasting

A group of researchers at the Lyell Centre in Edinburgh formulated a way to use math formulas to help forecast earthquakes. The team describes translating the movement of a particular type of rock to mathematical equations, leading to the development of a predictive...

Seimei telescope detects superflare 20 times larger than those emitted by our own sun

Astronomers from Kyoto University's Graduate School of Science and the National Astronomical Observatory of Japan have succeeded in detecting 12 stellar flare phenomena on a red dwarf 16 light-years away using the 3.8 meter Seimei telescope. This new instrument...

Study suggests the Moon is millions of years younger than previously thought

A new study suggests that the Moon is much younger than what was previously thought-- about 85 million years younger. Lunar rock samples collected on the Apollo missions are not old enough to confirm the normally accepted 4.51 billion-year for the Moon's age,...

Study reveals hundreds of ancient volcanic eruptions in New Zealand

Scientists revealed evidence of hundreds of ancient eruptions in New Zealand after reconstructing 350 000 years of volcanism across the North Island. These explosions would cause widespread havoc if they occurred in the present time. The researchers focused on...

Volcanic vent detected in the Dayoukeng area of the long-resting Tatun Volcano Group, Taiwan

Seismologists have discovered a volcanic conduit forming across the Dayoukeng area of the Tatun Volcano Group in northern Taipei, Taiwan. The team also found proof that Tatun volcanoes are still active-- if an eruption takes place, the volcanic conduit near...

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...

MagLab geochemists solve mystery of Earth's disappearing crust

A team of geochemists based at the Florida State University-headquartered National High Magnetic Field Laboratory has discovered significant clues about the sections of the crust that vanishes back into the Earth. The researchers provided new evidence showing that...
