Is Mt Rainier Likely to Erupt Again
When volition Mount Rainier erupt once again? Magma study offers clues.
Scientists take mapped the electrical and magnetic signatures of magma flows beneath Mount Rainier, which scientists wait to erupt once more.
Mount Rainier is seen from the road to Paradise Visitor Center at Mountain Rainier National Park in June.

Experts accept mapped a huge magma reservoir below Mount Rainier in Washington country that begins melting deep in the Earth's drape before pushing upwards to where it will eventually exist tapped for eruption.
Researchers from the United States and Norway used seismic imaging and the measurement of variations in electrical and magnetic fields to create a detailed road map of the pathway molten rock takes to the surface.
Their findings, published this week in the journal Nature, are aimed at helping experts empathise the volcano's inner workings, and eventually determine when information technology might again erupt.
A land landmark, Mount Rainier terminal erupted in the 19th century. It is widely expected to erupt again, according to the U.Southward. National Park Service.
The tallest volcano and 5th-highest summit in the face-to-face United States, information technology towers some 14,410-anxiety (4,392 meters) about 58 miles (93 km) southeast of Seattle, from nearly of which it is visible.
Phil Wannamaker, a geophysicist at the University of Utah, said the new images were most detailed to date, but that they did not provide any information on the timing of future eruptions by Mountain Rainier or other Cascade Range volcanoes.
The volcano'due south magma forms deep in the Globe's curtain, the layer between the planet'southward crust and its core. The magma, which is fluid molten rock, and then flows upwards to a pool about five miles (viii km) beneath the peak, the study found.
The pool appears to be well-nigh five to 10 miles (eight km to xvi km) thick and the same width, the researchers said.

Beloved Reader,
About a year ago, I happened upon this argument well-nigh the Monitor in the Harvard Concern Review – under the charming heading of "do things that don't involvement you":
"Many things that end up" existence meaningful, writes social scientist Joseph Grenny, "have come up from conference workshops, manufactures, or online videos that began every bit a chore and ended with an insight. My piece of work in Kenya, for instance, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, nosotros call things 'boring' merely because they lie outside the box nosotros are currently in."
If you lot were to come up with a punchline to a joke about the Monitor, that would probably exist information technology. We're seen every bit existence global, fair, insightful, and perhaps a flake too earnest. Nosotros're the bran muffin of journalism.
But y'all know what? We modify lives. And I'm going to debate that we change lives precisely because we force open that too-small box that most human beings remember they live in.
The Monitor is a peculiar trivial publication that's difficult for the world to effigy out. We're run past a church, but we're not only for church members and we're non about converting people. We're known as being fair even every bit the world becomes as polarized as at whatever time since the paper's founding in 1908.
We have a mission beyond circulation, we want to bridge divides. Nosotros're nearly kicking down the door of thought everywhere and saying, "Yous are bigger and more capable than you realize. And we can show it."
If y'all're looking for bran muffin journalism, you can subscribe to the Monitor for $fifteen. Y'all'll get the Monitor Weekly mag, the Monitor Daily e-mail, and unlimited access to CSMonitor.com.
