Researchers at USGS and international universities reveal that hot vaporized seawater contributes to the formation of new oceanic crust. High-pressure images of lava cavities show molten salt and exotic minerals formed from steam bubbles, challenging previous assumptions about seawater's boiling point at great depths.

Researchers suggest a similar eruption under the Indian Ocean before the dinosaurs' extinction had a devastating impact on the environment. The eruptions were caused by mantle plumes, which can last between one and two million years and eject over 1 million cubic kilometers of lava.
Researchers discover new life forms living in extreme environments, such as gold mines and volcanic rocks, providing clues to the origins of life on Earth and potentially on Mars. These microorganisms may be using nuclear energy or toxic waste as fuel, shedding light on the diversity of possible fuel sources for life.
University of Cincinnati geology graduate student Keri Craven investigates how Hawaiian volcanoes age by analyzing rock samples and applying computer models. Her research suggests that the weight of the volcano may drive its aging process.

Recent geophysical data shows Mauna Loa's summit caldera swelling at a rate of 2-2.5 inches per year, indicating magma accumulation. Scientists warn that this could be a precursor to an eruption, which would be the first time imaged with precise clarity.
Scientists discovered well-preserved carbon dioxide and other compounds in deep-sea basalt, providing a rare glimpse into the Earth's mantle composition. This data may help determine the rate at which carbon dioxide is supplied to the atmosphere through volcanoes.
Geologists analyzed rare rock samples from California and Oregon, which contain large amounts of osmium, a key element in the Earth's core. The findings suggest that these rocks came from hotspots at the core-mantle boundary, providing valuable clues to the Earth's core composition.
Researchers are studying the chemical signatures of lavas from the Rift Valley in Turkana to understand the evolution of mantle plumes and how continents split apart. The study suggests that a mantle plume was present in the area 35 million years ago, contributing to the formation of the African Rift Valley.

A Rutgers researcher discovered the rapid revival of life around hydrothermal vents on the Pacific Ocean floor after a lava flow appeared to exterminate it. Over 500 new species have been found at these sites, including unique organisms like giant tube worms and hairy Pompeii worms.
A Temple University geologist and his team were visiting Mt. Etna when they received word of an impending eruption, which was predicted to the minute. The team had been working on a sensor that measures gas composition to predict eruptions, and their prediction marked a potential breakthrough in volcanic prediction.
Researchers have solved a long-standing volcanic mystery by finding a tear in the Pacific Plate, leading to the melting of cold slab material and altering its chemical makeup. This discovery sheds new light on the formation of adakites, a type of lava found in various parts of the globe.
Massive sheets of lava produced by flood basalt eruptions generated intense heat, pushing ash and gas into the upper atmosphere and causing dramatic global-scale climate shifts. These events are now believed to have contributed to mass extinctions, including those that wiped out dinosaurs.
Scientists have gained a clearer picture of massive volcanic eruptions by analyzing lava composition, indicating that the lava originated from the lower mantle. The findings suggest that the eruptions played a role in the greatest mass extinction event in Earth's history, wiping out up to 95% of plant and animal species.
