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.
The folks at MyTopo.com are now printing supersized topo maps; large enough make a huge 8′ x 5′ (or 5′ x 8′) map that will look fantastic on the wall of your office, conference room, lobby, cabin or den. These maps are custom-centered on any location that you pick using their online map-making tool.

Raven Maps are beautiful examples of shaded-relief wall maps that display the elevation of a state in vibrant colors. These large maps look great in a classroom, den or office. Use one to mark the locations of your work or company.
“Just after midnight on January 3, 1983, a small fissure opened within Napau Crater on Kilauea Volcano, spewing red-hot lava. Within hours, additional fissures stretched 6 kilometers down the volcano’s East Rift Zone. Thirty years later, the Pu’u ’O’o-Kupaianaha eruption continues, making it the longest eruption at Kilauea in recorded history. Since the eruption began in 1983, lava has poured almost continuously from a cluster of vents on the eastern flank.” Quoted from the Earth Observatory image release.
USGS has published “Tohoku-Oki Earthquake Tsunami Runup and Inundation Data for Sites Around the Island of Hawai‘i“. It contains a number of maps, photos and descriptions of tsunami damage on the island.
A magnitude 7.7 earthquake beneath the Queen Charlotte Islands region, off the west coast of British Columbia, Canada triggered a tsunami heading across the Pacific Ocean. Evacuation warnings were issued for coastal areas of Hawaii and for shoreline communities in British Columbia.
“A deep connection about 50 miles underground can explain the enigmatic behavior of two of Earth’s most notable volcanoes, Hawaii’s Mauna Loa and Kilauea. The study, the first to model paired volcano interactions, explains how a link in Earth’s upper mantle could account for Kilauea and Mauna Loa’s competition for the same deep magma supply and their simultaneous “inflation,” or bulging upward, during the past decade.”
“Recently, Hawaiian Volcano Observatory scientists have been asked if Hawaiʻi Island’s geothermal development causes subsidence of the ground surface, as has been observed at U.S. mainland geothermal areas, such as those in California—Coso, Geysers, the Imperial Valley, and Casa Diablo in the Mammoth Lakes area.”
Alaska has a glut of natural gas and an LNG export facility. However, one of the reasons that it can not ship the gas to other ports in the United States is a law that requires the transporting vessel to be built, owned, registered and crewed by U.S. citizens. There are no available ships that meet these requirements.
Hawaii imports all of its fossil fuels, however, if it imports natural gas that fuel will more likely come from Canada or Australia than from anywhere in the United States – because the United States does not build LNG tankers.
“The United States has 169 active volcanoes. More than half of them could erupt explosively, sending ash up to 20,000 or 30,000 feet where commercial air traffic flies. USGS scientists are working to improve our understanding of volcano hazards to help protect communities and reduce the risks.” Quoted from the USGS video release.
“This clip, captured by a video camera on the rim of Halema’uma’u to the southwest of the vent, shows a small slice of the western rim of the vent collapsing into the lava lake.” Quoted from the USGS video description.
“Shown here are two natural-color views: a close-up of the Kilauea Caldera and the Hawaiian Volcano Observatory, and a wide-area view showing Mauna Ulu and Pu’u ’O’o. Within the Kilauea Caldera lies Halema’uma’u Crater. A small plume of water vapor emerges from this crater and blows toward the southwest.” Quoted from the NASA image release.
“Scientists have discovered an outbreak of coral disease called Montipora White Syndrome in Kāneʿohe Bay, Oʿahu. The affected coral are of the species Montipora capitata, also known as rice coral. Rice corals provide valuable habitat, shelter, and foraging grounds for a variety of tropical marine fish and invertebrates and provide the fundamental structure of coral reefs.” Quote from the USGS press release.
“This year, the USGS is proud to celebrate 100 years of continuous volcano monitoring in the United States. Monitoring began in 1912, when Thomas A. Jaggar, Jr., of the Massachusetts Institute of Technology, founded the Hawaiian Volcano Observatory (HVO) in the then U.S. territory of Hawai‘i.” Quoted from the USGS press release.
