The Hawaiian Volcano Observatory is part of the U.S. Geological Survey, the science agency of the U.S. Department of Interior. Our job is to obtain and share science-based information about the ...

A new instrument type has discovered evidence of a volcanic process on the Moon that had only been seen on Earth. “Before the 1950’s, most scientists thought the craters on the Moon were from ...

Scientists compare volcanic cones on Earth and Mars to explain how gas-rich magma forms scoria cones. Spacecraft observations and Earth analog sites provide evidence of similar eruptive processes.

A giant mound near the Moon’s south pole appears to be a volcanic structure unlike any other found on the lunar surface, according to new research. The formation, known as Mafic Mound, stands about ...

A decrease in seismic activity while magma continues to accumulate underground in Iceland has left scientists unsure of what may happen next, including whether an eruption would occur in the area they ...

When we think of ice on Mars, we typically think of the poles, where we can see it visibly through probes and even ground-based telescopes. But the poles are hard to access, and even more so given the ...
