Rise and fall of underwater volcano revealed by sonar

Volcano World: Supplement - Sun, 05/13/2012 - 17:41

More great stuff from the researchers studying Monowai and undersea volcanism near Tonga. In a period of less than a month, researchers noted “huge changes” in the height of the volcano – according to a recent article in Nature Geoscience (Watts, A.B., Peirce, C., Grevemeyer, I., Paulatto, M., Stratford, W., Bassett, D., Hunter, J., Kalnins, L., de Ronde, C. & Lamarche, G. 2012. Rapid rates of growth and collapse at Monowai submarine volcano, Kermadec arc. Nature Geoscience)

This research into the Monowai volcano provides a fascinating insight into the little-known world of submarine geology. You can read more and view a 360 degree model of the changes at this webpage from BBC News

This is the same group that showed us an entire chain of mountains marching to subduction at the Pacific / Indo-Australian plate boundary in 2011. You can read that full article here.

Volcanoes Vex Air Force Base Relocation

Volcano World: Supplement - Thu, 03/08/2012 - 22:36

The proposal to relocate the 18th Aggressor Squadron’s 21 F-16s from Eielson, located 25 miles southeast of Fairbanks, to Joint Base Elmendorf-Richardson in Anchorage is intended to save money. It’s part of an $8.7 billion dollar cut to the Air Force budget. Alaska is one of 33 states with bases affected by proposed cuts.

Alaska’s congressional delegation and Gov. Sean Parnell expressed that concern in a letter sent Wednesday to the Air Force’s secretary and chief of staff stating that “When volcanoes near Anchorage erupt, the air space can close. While the Air Force has measures in place to respond to a volcanic eruption, the cost of relocating the fighter planes to another base would be increased if the F-16s were at Elmendorf-Richardson.”

_____________________________

So…. the issue here as I’m reading it is moving from 25 miles SE of Fairbanks to Anchorage where there is a greater risk of ash.

Well…. let’s take a closer look at the situation…

Here’s a map of Alaska near Anchorage from the Alaka Volcano Observatory.

Upwind from Anchorage we have Spurr

and Redoubt

Next to Fairbanks we have (also from AVO):

My humble opinion is … don’t move the planes. Just sayin’

Earthquake Swarm Rumbles in Hawaii

Volcano World: Supplement - Sat, 02/25/2012 - 10:24

Current Seismic Activity

The U.S. Geological Survey’s Hawaiian Volcano Observatory reports the Kaoiki seismic swarm continues about three miles Northwest of Halemaumau Crater with increased activity overnight with two magnitude 4+ earthquakes Friday (Feb 24).

As of 7:15 a.m. Friday 78 earthquakes were recorded in the previous 24 hours with 74 of these were related to the earthquake swarm, two were in the upper East rift zone and two were on the South flank faults.

The IAVCEI 2012 Calendar

Volcano World: Supplement - Sun, 02/19/2012 - 23:18

Every year, the IAVCEI (the International Association of Volcanology and Chemistry of the Earth’s Interior for the newbs…) puts out the call for the most amazing volcano pictures (I’m sure glad I’m not on the decision making committee…) and this years calendar is very cool.

The 2012 IAVCEI Volcano Calendar is now available at:

Calendars.com
http://www.calendars.com/Weather/Volcanoes-2012-Wall-Calendar/prod201200004736/?categoryId=cat00387

OR, you can also buy the calendars directly from the publisher at:
http://www.browntrout.com/calendars/product.asp?MGID=-1&IID=11751

I’d suggest buying one – If this one doesn’t sell well…, they might do a “Men of Geology” calendar next year…

Welcome CalVo!

Volcano World: Supplement - Wed, 02/15/2012 - 21:53

The USGS Volcano Hazards Program issued a press release announcing the establishment of the USGS California Volcano Observatory (CalVO), which replaces the Long Valley Observatory (LVO). Like LVO, CalVO operates out of existing facilities within the USGS Menlo Park (CA) campus with Margaret (Maggie) Mangan as the Scientist-in-Charge.

The URL for the press release is http://www.usgs.gov/newsroom/article.asp?ID=3097.

This event also coincides with the release of a new CalVO website and the redirect and removal of the old LVO website.

The new website address is: http://volcanoes.usgs.gov/observatories/calvo/.

Establishing CalVO is the most visible part of a general restructuring of the responsibilities of the five observatories operated by the US Geological Survey.

The California Volcano Observatory watches over volcanoes in California and Nevada;
the Cascades Volcano Observatory (CVO) is responsible for volcanoes in Washington, Oregon and Idaho;
the Alaska Volcano Observatory (AVO) monitors volcanoes in Alaska and the Commonwealth of the Northern Marianas;
the Hawaiian Volcano Observatory (HVO) monitors activity in Hawaii;
and the Yellowstone Volcano Observatory (YVO) is responsible for volcanoes in Montana, Wyoming, Colorado, Utah, Arizona, and New Mexico.

How many volcanoes are there in the United States??

Volcano World: Supplement - Sun, 02/12/2012 - 18:31

Good question! (I’m looking at you Mr. Jindal…)

Here’s a list compiled a few years back from Volcanoes of North America: United States and Canada, by Wood and Kienle. They list all volcanoes that are younger that 5 million years old and are morphologically distinct. If your state is not listed it probably means there are no volcanoes there or they are the remnants of something older than 5 million years! (let the floods commence)

According to them, there are about 262 volcanoes and volcanic fields in North America.

Location Number of Volcanoes
Canada* 21 USA* 241 Alaska* 108 Arizona* 9 California* 24 Colorado* 1 Idaho* 6 Hawai’i* 19 Nevada* 7 New Mexico* 16 Oregon* 34 Utah* 6 Washington* 9 Wyoming* 2

Why is magma called lava after it erupts?

Volcano World: Supplement - Mon, 01/23/2012 - 03:21

Magma comes from an Italian word that means a thick, pasty substance, which is how molten rock behaves within the Earth.

Lava, another Italian word, means to slide, which is what molten rock does once it reaches the surface.

Pu`u `Ō `ō cone, September 1983. Image courtesy of the USGS Hawaiian Volcano Observatory.

All magma contains dissolved gases. As it rises to the surface, the pressure is reduced and the dissolved gases can escape. If the lava is runny (not viscous), the gases can escape easily and the lava will just run down the landscape (somewhat like syrup).

However, if the lava is thick and pasty (highly viscous), the gases cannot escape and they build up tremendous pressure (like a shaken soda bottle) causing the volcano to erupt/explode violently forming volcanic ash, dust, pumice, etc., and lava.
