Roadside Geology Guides|
November 25, 2013 | Geology.com Store
Since 1972 the “Roadside Geology” series has provided introductory information on the geology of states and small regions of the United States.
The books provide a combination of maps, travel logs, photos and commentary for the geology that can be seen along highways or visited at parks and public viewing areas. They are popular with geologists, teachers, students and others who are interested in the Earth.

We have posted views of Earth from NASA’s Suomi satellite that show night illumination and natural gas flaring for oil industry sites in the Bakken Formation, Eagle Ford Shale, Alaska North Slope, United States Gulf, Mexican Gulf, Venezuela Orinoco Field, Brazil offshore basins, North Sea, North Africa onshore, west Africa offshore, and Persian Gulf.
Activity at Veniaminof|
October 13, 2013 | Alaska Volcano Observatory
“The latest phase of the 2013 eruption of Veniaminof resumed on October 6, 2013 after a month-long pause in activity. Similar to activity observed during the summer of 2013, the eruption is characterized by lava effusion and fountaining and production of intermittent small steam, gas, and ash plumes that rise hundreds of feet above the active vent.” Quoted from the AVO weekly report.

If you spend time in bear country knowing how to react to a bear encounter and what to do if you are attacked could save your life.
If you don’t know where bears live here is a map of the geographic ranges for black, grizzly and polar bears in North America.
Walking Away from One of the World’s Largest Gold Discoveries?|

September 17, 2013 | CNN
New measurements made by Alaska’s Statewide Mapping Initiative and the United States Geological Survey have placed a new altitude on the summit of Mount McKinley, America’s highest mountain. It’s official height is now 20,237 feet instead of the previous 20,320 feet. (It didn’t really “shrink”. Just better measurement methods.)
Tundra Recovering from a Massive Fire|
September 15, 2013 | University of Alaska Fairbanks
“Despite the size and severity of the massive 2007 Anaktuvuk River fire on Alaska’s North Slope, much of the arctic vegetation has recovered and the tundra is likely to return to its pre-fire condition.” Quoted from the University of Alaska Fairbanks press release.
Potential Tsunami Impact on Southern California from an Alaska Earthquake|
September 8, 2013 | USGS
“The Science Application for Risk Reduction tsunami scenario depicts a hypothetical but plausible tsunami created by an earthquake offshore from the Alaska Peninsula and its impacts on the California coast. ” Quoted from the USGS Newsroom.
400 New Topo Maps for Alaska|
September 4, 2013 | United States Geological Survey
“More than 400 new topographic maps are now available for the state of Alaska. The new maps are part of the U.S. Geological Survey Alaska Mapping Initiative, to update foundational data for the state and to replace the existing maps that are about 50 years old.” Quoted from the USGS Newsroom.
Detecting Large Landslides in Remote Areas|
September 4, 2013 | NASA Earth Observatory
“Even when they occur in remote areas, large landslides can dam rivers and lead to devastating downstream floods. [...]
Automated earthquake detection systems are tuned to monitor intense, “short-period” waves produced by sudden slips along tectonic faults. Landslides produce seismic waves as well, though their short-period signal is weak. Instead, they make powerful long-period waves that are sometimes detectable at great distances.” Quoted from the Earth Observatory article.
Lava-Ice Interactions at Veniaminof Volcano in Alaska|

Frozen Landslides in Alaska|
August 21, 2013 | Alaska Dispatch
A slow-moving landslide of ice and frozen debris heading towards the Dalton Highway could cut off the only ground access to the North Slope oil fields. This is one of many frozen landslides causing problems in Alaska
July 17, 2013 | University of Washington
The University of Washington has a press release titled: “Some volcanoes ‘scream’ at ever-higher pitches until they blow their tops” that explains new research on harmonic tremors.
Strongest Seismic Activity of 2013 at Pavlof|
June 25, 2013 | Alaska Volcano Observatory
“Vigorous eruptive activity indicated by a distinct increase in seismicity beginning around 6:50 UTC (22:50 AKDT) last evening is continuing. The level of seismicity for the past 11-12 hours has been the strongest seismic activity detected so far during the 2013 eruption of Pavlof Volcano.” Quoted from the Alaska Volcano Observatory.
The Permafrost Timebomb?|
June 13, 2013 | NASA
Over hundreds of thousands of years the Arctic permafrost has accumulated an enormous store of organic carbon. As it thaws from climate change the plant debris will decay and carbon dioxide and methane will be release into the atmosphere. Permafrost contains at least 4x more carbon than fossil fuel burning has produced since 1850.
Rare Earth Elements in Alaska|
June 7, 2013 | USGS
“A unique deposit of heavy rare earth elements at Alaska’s Bokan Mountain could help scientists understand how rare earth element deposits form. [...] Currently, very little is known about the geologic setting in which REE deposits form. Understanding these geologic settings and how they come to be is a crucial step to being able to determine where mineable concentrations of REE might be found.” Quoted from the USGS press release.
The Most Powerful Eruption of the 20th Century|
June 5, 2013 | Geology.com
The most powerful volcanic eruption of the 20th Century occurred on June 6, 1912. People in Juneau, Alaska heard the noise over one hour after the eruption occurred. For the next forty years the eruption was blamed on the wrong volcano.
