A team of scientists say they have evidence that a "super volcano" may be brewing underneath Mount St. Helens, NewScientist.com reports. Researchers say indicators suggest Mount St. Helens and other northwest volcanoes are plugged into a huge subterranean pool of magma that could one day burst to the surface in a "super" eruption. If what they believe is true, the structure beneath the mountain would be comparable in size to the biggest magma chambers ever discovered, such as the one below Yellowstone National Park.

In January 2009, ICR received a copy of a recent ministry letter published by television personality Dr. John Ankerberg. For many years, Dr. Ankerberg has skillfully tackled tough issues related to the church, society, the Middle East, and other topics of interest to believers. Christians everywhere need to be informed, challenged, and also taught sound doctrine—there is no substitute for the Bible. However, the January letter from Dr. Ankerberg’s television ministry reveals a dangerous trend toward subjugating the accuracy, understandability, and authority of the Bible to the foolish musings of men—namely, scientists who deny that God’s revelation in the book...

MOUNT St. HELENS, Wash. - On May 18, 1980, the once bucolic ice-cream cone shape that defined Mount St. Helens in Washington state disappeared in monstrous blast of ash, rock, gas, and heat. ... And inside the volcano, which was once a soft dome of snow but is now a gaping, steaming menace with an unpredictable streak, an unexpected phenomenon is taking place: a glacier is growing. ... But Walder cautions that a glacier inside a volcano leads a tenuous existence. A surge in volcanic activity, especially an eruption, could melt away the glacier in the space of a day,...

NEW YORK — Mt. St. Helens awoke Tuesday afternoon with a mild eruption, spewing a plume of steam and ash into the Washington State sky. The event was most probably was caused by growth of the new lava dome inside the crater, experts said. During such eruptions, changes in the level of activity can occur over days to months. The eruption could intensify suddenly or with little warning and produce explosions that cause hazardous conditions within several miles of the crater and farther downwind. Small lahars — a debris flow — could suddenly descend the Toutle River if triggered by...

VANCOUVER, Wash. - Mount St. Helens shot a steam and ash plume at least 16,000 feet into the air Monday after a large rockfall from the lava dome in the volcano's crater, scientists said. Pilots reported the plume rose between 16,000 and 20,000 feet in the air, scientists at the Cascades Volcano Observatory said. The rockfall coincided with a magnitude 3.1 earthquake shortly after 9 a.m. Monday at the mountain, scientists said. Such events are expected during growth of the lava dome, they said. "There is no evidence of an explosion associated with this event," the observatory said in a...

If the skies are clear as forecast, volcano watchers who turn out for the reopening of the Johnston Ridge Observatory on Friday will get a spectacular view of a hulking slab of rock that's rapidly growing in Mount St. Helens' crater. It's jutting up from one of seven lobes of fresh volcanic rock that have been pushing their way through the surface of the crater since October 2004. The fin-shaped mass is about 300 feet tall and growing 4 feet to 5 feet a day, though it occasionally loses height from rockfalls off its tip, said Dan Dzurisin, a geologist...

Earthquakes At Mount St. Helens Collapse Dome August 1, 2005By BERNARD CHOI / KING 5 News MOUNT ST. HELENS, Wash. - The rumblings at Mount St. Helens have been so strong, the lava dome has collapsed. Scientists are trying to figure out what's behind the recent string of stronger-than-normal quakes at the volcano. In the last 24 hours, the seismograph has recorded three earthquakes with a magnitude at or near 3.0, and these quakes are shaking things up inside the crater. St. Helens is at it again, shaking and rattling and sending the seismograph needle into overdrive. Compare a printout...

Learned a few new things last week, leading to this week's posting: The town of Orting, in Washington, sits right on top of the landslide deposits from the Electron mudflow generated by Mount Rainier. A buried tree stump excavated from the Electron mudflow. Ash layers from Mt. St. Helens. I learned last week that after the 1850 BC eruption, the native population abandoned the area for about 2000 years. That's a pretty long length of time for "you don't want to live in that neighborhood" to get passed along around the campfire.

Experts Detect Tremor at Mount St. Helens 2 hours, 9 minutes ago U.S. National - AP By DAVID AMMONS, Associated Press Writer MOUNT ST. HELENS NATIONAL MONUMENT, Wash. - Scientists detected a volcanic tremor at Mount St. Helens early Sunday, just hours after officials raised the volcano's alert level, cleared hundreds of visitors from the area and warned a major eruption was imminent. AP Photo Reuters Slideshow: Mount St. Helens Erupts Sunday's tremor lasted about 25 minutes and was milder than the 50-minute tremor that followed a steam release Saturday, said Jeff Wynn, chief scientist for volcano hazards at the...

Two Volcanoes Could Erupt In Washington State, seismologists are on alert this morning as earthquakes rock Mount Saint Helens. Plus the rumbling of the world's largest volcano, Mauna Loa in Hawaii shows no signs of stopping. The last time Mount Saint Helens erupted was in May of 1980. During the eruption, a portion of the mountain was blown to pieces, 57 people were killed and as many as 700 earthquakes were recorded in one day. In Hawaii, Mauna Loa hasn't erupted in 20 years. Now, there have been dozens of earthquakes felt and measured at Manau Loa. Now scientists say...

Small earthquakes rattled Mount St. Helens at the rate of one or two a minute Monday, and seismologists were working to determine the significance of some of the most intense seismic activity in nearly 20 years. Carbon dioxide and sulfur gas samples collected above the volcano - which erupted to devastating effect in 1980 - will help scientists figure out what is going on beneath the 925-foot-high dome of hardened lava within the mountain's gaping crater. They want to know whether the quakes are the result of water seeping into the mountain or magma moving under its crater. In either...

I was just reading another thread on this subject, when I came to the line stating that the quake intensity and frequency had diminished on Monday. That it complete eyewash - for whom I don't know. Evidently they don't want to scare the masses - just in case. The thread I'm referring to is located here.Below I'm posting the last three seismographs for you to see that this claim is bogus indeed. This swarm is appearing to grow, with over 1,000 earthquakes so far since Thursday. The depth of the quakes is still near the surface, and they are saying...

Submitted at 6:00 pm PDT, September 23, 2004-- Volcanoes in the Cascade Range are all at normal levels of background seismicity. Other volcanoes include,Mount Baker, Glacier Peak, Mount Rainier, Mount Adams, and Mount St. Helens in Washington State; Mount Hood, Mount Jefferson, Three Sisters, Newberry, and Crater Lake, in Oregon; and Medicine Lake, Mount Shasta, and Lassen Peak in northern California. USGS Cascades Volcano Observatory, the Pacific Northwest Seismograph Network at the University of Washington, and the USGS Northern California Seismic Network and Volcano Hazards Team in Menlo Park, California, monitor the major volcanoes in the Cascade Range of northern...
