Electrical Images Show Upward Flow of Fluids to Magma Chamber

By measuring how fast Earth conducts electricity and seismic waves, a University of Utah researcher and colleagues made a detailed picture of Mount Rainier’s deep volcanic plumbing and partly molten rock that will erupt again someday.

“This is the most direct image yet capturing the melting process that feeds magma into a crustal reservoir that eventually is tapped for eruptions,” says geophysicist Phil Wannamaker, of the university’s Energy & Geoscience Institute and Department of Civil and Environmental Engineering. “But it does not provide any information on the timing of future eruptions from Mount Rainier or other Cascade Range volcanoes.” (more…)

Scientists want a detailed picture of Mount St. Helens’ plumbing

Earth scientists are laying plans for a two-year study covering a broad area of southwestern Washington to develop a better understanding of how Mount St. Helens gets its supply of volcanic magma.

“The main goal is to understand the plumbing system of the mountain,” said Kenneth Creager, a University of Washington professor of Earth and space sciences who is leading the study. (more…)

‘Mount Sharp’ on Mars Links Geology’s Past and Future

One particular mountain on Mars, bigger than Colorado’s grandest, has been beckoning would-be explorers since it was first sighted from orbit in the 1970s. Scientists have ideas about how it took shape in the middle of ancient Gale Crater and hopes for what evidence it could yield about whether conditions on Mars have favored life.

No mission to Mars dared approach it, though, until NASA’s Mars Science Laboratory mission, which this August will attempt to place its one-ton rover, Curiosity, at the foot of the mountain. The moat of flatter ground between the mountain and the crater rim encircling it makes too small a touchdown target to have been considered safe without precision-landing innovations used by this mission.
