Earth's magnetic field, otherwise known as the geomagnetic field, is the magnetic field that extends from the Earth's inner core out into space, where it deflects harmful radiation from the Sun.
Earth's magnetic field is what allows us to exist. It deflects harmful radiation. It keeps our water and atmosphere in place. But now it's acting up -- and nobody knows why.
The Richat Structure, also known as the Eye of the Sahara or blue eye of Africa, is a prominent geological circular feature in the Sahara desert in Mauritania near Ouadane. It is nearly 50 kilometers across and very visible from space. Initially inte
The scientific exploration of Greenland has extended for centuries because of its remote location and ice cover. Exploration of features beneath the ice is a relatively new development, owing to the mid-20th century advent of borehole drilling thro
The high and moderate threat volcanoes according to the report mostly consist of volcanoes located in Alaska. These volcanoes have the potential to significantly damage national and international aviation, as well as a potential to cause regional and
As demonstrated by dramatic images of lightning coursing through volcanic plumes, the ash is electrically charged. The interplay of electrostatic forces can lift that ash higher than previously thought, according to Genge.
Mount Vesuvius is what's called a composite volcano. Here the magma is made from lots of different types of rocks, liquids and gases, forced deep underground by plate tectonics. Under pressure and heat, this volatile mixture melts, and then rises b
When the seismic waves travel through the cores of tectonic plates - known as cratons, and looking something like inverted mountains - they move faster than they should based on current models of their composition.
A 100-foot-long fissure near the Yellowstone supervolcano has prompted the closure of parts of Teton National Park. Coupled with the Steamboat geyser's newly active status, fears of an eruption at the Yellowstone caldera are increasing.
Hawaii is known for its volcanoes, but most volcanoes on earth exist along tectonic plate lines. Hawaii does not! What causes Hawaii to form, and how is it related to the mystery of a magnetic bar code across the Pacific Ocean?
The largest geyser – known as the Steamboat Geyser – located above the Yellowstone Supervolcano has begun to erupt underground. But experts at Yellowstone National Park claim to have seen the Steamboat Geyser erupt on Thursday night.
Yellowstone is home to several faults, and has a long history of seismic activity. As natural processes occur beneath the surface and 'stress effects' from past events continue to maintain their hold, the area remains a 'hotbed of seismicity an
It has long been known that the Earth constantly generates a low-frequency vibrational signal.
The first attempt to detect this hum was made in 1959, but it wasn't until 1998 that scientists finally proved its existence.
Since then, there ha
A Siberian super-volcano is worrying scientists after it's shocking and sudden eruption flung hot ash six miles into the sky. This volcano is one of the most active in Russia.
Why is the west coast shaking so violently? According to the latest data from Earthquake Track, there have been 698 earthquakes in California within the past 30 days.

In the underground rivers and flooded caves of Mexico's Yucatan Peninsula, where Mayan lore described a fantastical underworld, scientists have found a cryptic world in its own right.
Warner Bros Pictures might want to rethink the shooting of San Andreas II – the sequel to the 2015 blockbuster about a massive earthquake striking the San Francisco Bay Area that starred the Rock, Paul Giamatti and a host of other A-list actors.
there is a large dead zone of animals and vegetation. Immediately outside this dead zone, vegetation has stopped growing and animals are migrating out of the area. New geysers and mud pots are springing up daily. You can physically see the ground bu
. Recognizing the nature of past sea-level rises (i.e., gradual or stepwise) during deglaciation is critical for informing models that predict future vertical behavior of global oceans. Here we present high-resolution bathymetric and seismic sonar
Earth's early Eocene period, also known as the Super Greenhouse period, was commonly believed to have concentration levels of carbon dioxide of as much as 2,000 parts per million (ppm). However, Dartmouth College researchers have discovered that it
"Okay, here's the bombshell, the volcanic eruption in Iceland. Since its first spewing of volcanic ash has, in just four days, negated every single effort you have made in the past year to control CO2 emissions on our planet.
Zealandia, a for the most part underwater landmass in the South Pacific, was declared the Earth's newest continent this year in a paper in the journal of the Geological Society of America. It includes Lord Howe Island off the east coast of Australi
But there have always been those who claim that oil is a natural substance that forms automatically in the Earth's mantle. They say that it is virtually everywhere, if you can drill deep enough to tap it.
Proponents of so-called "abiotic oil" c
