"Discovery: Large Undersea Faults Pulling Apart Pacific Plate"

Geoscientists from the University of Toronto have discovered large undersea faults on the Pacific plate, challenging the traditional model of rigid ocean floor plates. These faults, some thousands of meters deep and hundreds of kilometers long, are pulling the plate apart due to enormous forces within it. The research sheds new light on plate tectonics and suggests that the Pacific plate is not as pristine as previously thought, with weaker sub-oceanic plateaus being more prone to tearing. This discovery could be linked to seismic activity and volcanism, overturning previous understanding of the Earth's dynamics.

Lost Continent Rediscovered After 375 Years

Geoscientists have discovered Zealandia, a continent that had been hidden for 375 years. Zealandia, also known as Te Riu-a-Māui, is approximately 1.89 million square miles in size and was part of the supercontinent Gondwana. It was first mentioned in 1642 by Dutch sailor Abel Tasman, but its existence was confirmed in 2017. Most of Zealandia is underwater, and it has only three territories. The discovery of Zealandia serves as an example of how something "very obvious" can take a long time to uncover.

"Lost Continent Found: Scientists Uncover 375-Year Mystery"

Geoscientists have discovered Zealandia, a continent that had been hidden for 375 years. Zealandia, which is 1.89 million square miles in size, was part of the supercontinent Gondwana over 500 million years ago. Despite being first mentioned by Dutch sailor Abel Tasman in 1642, it wasn't until 2017 that scientists confirmed its existence. Most of Zealandia is underwater, and it has only three territories. This discovery highlights how something "very obvious" can take a long time to uncover.

"USGS Scientists Investigate Long Valley Volcano"

USGS geoscientists visited the Long Valley Caldera in California to examine volcanic deposits and study the region's complex eruption history. The excursion included visits to geothermal features, power plants, and monitoring stations. The gathering facilitated knowledge exchange and discussions among experts, aiming to challenge and revise scientific assumptions. Ongoing work in the area involves installing and maintaining sensors, monitoring earthquake swarms, and conducting various geologic studies.

Exploring Zealandia: Unveiling Earth's Long-Lost Continent

Geoscientists have discovered Zealandia, a continent that had been hiding in plain sight for almost 375 years. Zealandia, which is 1.89 million square miles in size, was part of the supercontinent Gondwana over 500 million years ago. Despite being first mentioned by Dutch sailor Abel Tasman in 1642, it wasn't until 2017 that geologists confirmed its existence. Most of Zealandia is underwater, and it has only three territories. This discovery serves as an example of how something "very obvious" can take a while to uncover.

"Breakthrough: Scientists Extract Historic Mantle Samples Through Earth's Crust"

Geoscientists aboard the JOIDES Resolution drilling vessel have collected pieces of Earth's rocky mantle from a mile beneath the North Atlantic ocean floor at an underwater mountain called Atlantis Massif. Although they did not drill into the mantle, they did recover the deepest mantle rock ever, getting samples from as deep as 4,157 feet. The samples can provide direct evidence for how ocean crust differs in composition from the upper mantle, better estimates of “the global composition of the bulk Earth,” and help researchers better understand how magma melts, flows, and separates.
