Gov Fallin declared a State of Emergency in Cleveland and McClain counties, Okla., due to the closure of James C. Nance Memorial Bridge.
“The bridge we just went and saw was at risk of collapsing and still is at risk of collapsing,” said Fallin.
The bridge, which facilitates flow of commerce and trade between portions of six counties, was shut down by ODOT on January 31 due to major structural damage. Some 22 cracks were detected in the truss system.
Lexington and Purcell are less than two miles apart. However, since the bridge closure, the 40-mile detour takes about 50 minutes to drive, dramatically increasing commute times and fuel expenses.
“This bridge is a safety hazard and is at risk of collapse,” said Fallin. “Keeping it open would have threatened lives. It had to close. Unfortunately, that has created an economic hardship, not to mention a severe inconvenience, for the people of Lexington and Purcell.”
The bridge is said to be “similar” to the Minnesota I-35W bridge that collapsed in 2007.
Opened in 1938, the 1,110-meter (3,642 ft) long bridge crosses the Canadian River and is one of the longest in the Sooner State. The cost of rebuilding could top $40 million.

Pavlof is erupting vigorously, exhibiting strongest seismic activity detected so far this year, characterized by intense, continuous tremor and intermittent explosions suggesting lava fountaining and ash production, Alaska Volcanoes Observatory (AVO) reported.
The wave of intense activity started late on Monday and continued into Tuesday, with trace ash fall reported in the community of King Cove about 30 miles southwest of the volcano.
AVO Daily Update – Tuesday, June 25, 2013 @ 12:33 PM AKDT (Tuesday, June 25, 2013 @ 20:33 UTC)
PAVLOF VOLCANO (CAVW #1102-03-)
55°25’2″ N 161°53’37” W, Summit Elevation 8261 ft (2,518 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
In its daily briefing AVO said:
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. The seismicity is characterized by intense, continuous tremor and intermittent small explosions that are likely associated with lava fountaining and ash production.

At this level of unrest it is likely that lava fountaining and ash emission are occurring. Lava fountaining is likely producing spatter-fed lava flows that are descending the flanks of the volcano over ice and snow and could be producing substantial steam plumes. These plumes probably contain variable amounts of ash. At the level of unrest observed over the past 11-12 hours, the volcanic plume has not been particularly ash rich; however, this could change if the character of the eruption changes and it remains possible for more robust ash plumes to be generated at any time. AVO is monitoring the eruption closely and will issue further information as it becomes available.
Mount Pavlof, one of the most active volcanoes in the U.S., has been erupting since May 13, spewing ash and lava at a low intensity.

Veniaminof Volcano Activity [Source: AVO]
Continued volcanic tremors suggest that the Veniaminof Volcano is still erupting, said AVO. Recent satellite images show elevated surface temperatures at the intracaldera cone; webcam images from Perryville show a light-colored plume rising above the rim of the intracaldera cone, some 8,200 feet a.s.l.
It is possible for activity at Veniaminof Volcano to increase above its current level at any time and more vigorous ash emissions may result. Sustained periods of volcanic tremor may correspond with continuous ash emission which may not be detected in satellite data, especially if ash plumes remain below 15,000 to 20,000 feet above sea level. Brief bursts of ash emission and small explosions with ash fall limited to areas on the flanks of the volcano are likely to occur while the volcano is at its current level of unrest. A larger explosive episode and associated ash emission is not expected at the current level of unrest; however, this remains possible and would be evident in seismic and satellite data.

Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
Activity Summary: At the summit, tiltmeters recorded the start of DI inflationary tilt and the lava lake level rose. At Pu`u `O`o vent in the middle east rift zone, there was no new activity within the crater but the Kahauale`a II lava flow remained active on the north base of the cone. To the southeast, the Peace Day pali flow remained active on the coastal plain while the main flow branch continued to enter the ocean in at least 2 locations spanning the Hawai`i Volcanoes National Park boundary. Gas emissions remained elevated. (HVO)
Recent Observations at the middle east rift zone vents: Only glow was seen from the east lava pond and spatter cones on the crater floor. The tiltmeter on the north flank of Pu`u `O`o cone recorded the start of DI inflationary tilt at 8 pm yesterday. GPS receivers on the north rim and south base of Pu`u `O`o cone recorded neither extension nor contraction since May 12. The most recent (preliminary) sulfur dioxide emission rate measurement was 300 tonnes/day on April 26, 2013, from all east rift zone sources; these values have ranged between 150 and 450 t/d in 2013; these measurements are made at a greater distance from the sources where the plume is more easily characterized.

According to press reports, an eruption from Benbow Crater occurred on 10 February [1979.] Gases from the eruption caused acid rainfall on the SW portion of Ambrym Island, destroying most vegetation within 24 hours, contaminating water supplies, and burning some inhabitants. Jean-Luc Saos, Director of Mineral Resources for the New Hebrides government, reported a high concentration of HCl and sulfur compounds in the volcanic gases. Although heavy ashfalls have occurred in the area in the past, this is the first report of acid rains. More …

A hazy layer of vog—volcanic fog—overlies Malekula and a few other islands of the Vanuatu archipelago in this natural-color satellite image. The source of the vog is Ambrym, a volcano in the southeast (lower right) corner of this scene. The haze extends over the Coral Sea several hundred kilometers to the northwest. Ambrym emits sulfur dioxide—the gas responsible for the formation of vog— intermittently. (Kilauea Volcano has recently affected the residents of Hawaii with similar vog emissions.) The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite acquired this natural-color image on October 6, 2009.

Ambrym, a large basaltic volcano with a 12-km-wide caldera, is one of the most active volcanoes of the New Hebrides arc. A thick, almost exclusively pyroclastic sequence, initially dacitic, then basaltic, overlies lava flows of a pre-caldera shield volcano. The caldera was formed during a major plinian eruption with dacitic pyroclastic flows about 1900 years ago. Post-caldera eruptions, primarily from Marum and Benbow cones, have partially filled the caldera floor and produced lava flows that ponded on the caldera floor or overflowed through gaps in the caldera rim. Post-caldera eruptions have also formed a series of scoria cones and maars along a fissure system oriented ENE-WSW. Eruptions have apparently occurred almost yearly during historical time from cones within the caldera or from flank vents. However, from 1850 to 1950, reporting was mostly limited to extra-caldera eruptions that would have affected local populations. Caption: GVP

On 29 September, people living in Chaitén town, 10 km SW of Chaitén’s Domo Nuevo 1 (Phase I) and Domo Nuevo 2 (Phase II) lava-dome complex, noticed that the eruption column was larger. Scientists conducted an overflight and saw a third lava dome (Phase III) in the SW area of the complex, which had filled up a depression left by a collapse on 19 February.
According to news articles from 2 October, increased seismicity at Gaua was detected during the previous two weeks. Villagers living nearby reported ashfall and sulfur odors.
An explosive eruption from Galeras on 30 September prompted INGEOMINAS to raise the Alert Level. An ash plume rose to an approximate altitude of 12.3 km (40,400 ft) a.s.l. and drifted E, then N. —GVP

USGS / YVO cite a combination of geological factors including:
However, YVO has not reported any anomalous changes in hot springs discharges, gas emissions …
In 2004 the Yellowstone caldera underwent period of accelerated uplift, clocking 7 cm/yr, or three times faster than in the recorded history; however the movement has now slowed down to a maximum rate of 4 cm/yr (or about 175 % of the pre-2004 records.)
The uplift is most noticeable at the White Lake GPS station, as has been discussed in our monthly YVO updates during the past year. As of late October 2007, the total uplift since 2004 at that location is about 17 cm. Chang and his colleagues credit the relatively rapid rise to recharge of magma into the giant magma chamber that underlies the Yellowstone Caldera. They also used numerical modeling to infer that the magma intruded about 10 km (6 miles) beneath the surface.
This interferogram provides a map view of ground movements at Yellowstone. Each color contour represents a line of equal uplift relative to the ENVISAT satellite between Sept. 2004 and Aug. 2006. The center of the uplift is an elliptical region stretching from the northeastern part of the Yellowstone Caldera (the dashed black line) to the southwest. This area of maximum uplift encompasses both Yellowstone’s resurgent domes, features long known for similar movements. During this time period, the north-rim uplift anomaly subsided (bullseye in the upper left part of the interferogram). The yellow lines are roads. The yellow triangles are locations of GPS stations with continuous data. The light blue lake within the caldera is Yellowstone Lake. Thin black lines are mapped faults. Figure courtesy of C.

Conclusion:
USGS / YVO: “At this time, there is no reason to believe that magma has risen to a shallow level within the crust or that a volcanic eruption is likely. ”
FEWW: Perhaps, a new mindset is needed to help understand the true nature, “utility function” and full range of all possible scenarios that might occur at the super volcano site. Let’s start looking at Yellowstone in the Big Picture frame. There may be a few sobering “surprises” in store!
NOTE: A small explosive eruption of Cleveland on 25 June prompted AVO to raise the Volcano Alert Level to Watch and the Aviation Color Code to Orange. An ash cloud that detached from the volcano was seen on satellite imagery moving S at an estimated altitude of 4.6 km (15,000 ft) a.s.l. No further activity was reported. On 27 June, AVO lowered the Volcano Alert Level to Advisory and the Aviation Color Code to Yellow. (Source: GVP)

Piton de la Fournaise. The massive Piton de la Fournaise on the island of Réunion is one of the world’s most active volcanoes. It is seen here in 1977 with a fresh black lava flow descending the outer NE flank of the shield volcano to the sea. An unvegetated summit lava shield (upper left) was constructed within an 8-km-wide caldera that is breached to the sea. Its sloping northern rim is marked by the diagonal vegetation line at the left. More than 150 eruptions have occurred since the 17th century, mostly from vents within the caldera. (Caption:Global Volcanism Program ).

Recent activity at the Kilauea volcano has increased atmospheric levels of sulfur dioxide in the districts of Kau and Puna, Hawaii, resulting in a spike of sulfur of 9 parts per million, which is considered to be extremely high. (Source)

“Garden of the Fugitives.” Plaster casts of some of the victims of Mount Vesuvius eruption [AD79] are still in the ruins of Pompeii. A few hours after Mount Vesuvius exploded Pompeii and its residents were buried under 3 meters of volcanic ash. Photo copyright: Aschwin Prein. See FEWW Fair Use Notice!

The skeletal remains of a young woman killed by the eruption of Mount Vesuvius in A.D. 79. The skeleton, unearthed from the ruins of Herculaneum in 1982, was named the “Ring Lady” because of the emerald and ruby rings found on the woman’s left hand. Two gold bracelets and gold earrings were also found by the woman’s side. (Source: Wikipedia)

New analysis by Purdue researchers of greenhouse gases shows that the emissions are greater in the southeastern United States than was previously thought. In this image, the amount of red represents the increased amounts of carbon dioxide in the atmosphere from previous estimates, and the blue represents a reduction in atmospheric CO2. Purdue assistant professor Kevin Gurney says the difference appears greatest in winter months when there are more emissions and less vertical air movement. (Purdue University image/Kevin Gurney)
The Vulcan Project is a NASA/DOE funded effort under the North American Carbon Program (NACP)to quantify North American fossil fuel carbon dioxide (CO2) emissions at space and time scales much finer than has been achieved in the past. The purpose is to aid in quantification of the North American carbon budget, to support inverse estimation of carbon sources and sinks, and to support the demands posed by the launch of the Orbital Carbon Observatory (OCO)scheduled for 2008/2009. The detail and scope of the Vulcan CO2 inventory has also made it a valuable tool for policymakers, demographers and social scientists.
