Stochastic reservoir simulation for the modeling of uncertainty in coal seam degasification
C. Özgen Karacan, Ricardo A. Olea
2015, Fuel (148) 87-97
Coal seam degasification improves coal mine safety by reducing the gas content of coal seams and also by generating added value as an energy source. Coal seam reservoir simulation is one of the most effective ways to help with these two main objectives. As in all modeling and simulation...

Emily Montgomery-Brown, Michael P. Poland, Asta Miklius
Rebecca Carey, Valerie Cayol, Michael P. Poland, Dominique Weis, editor(s)
2015, Book chapter, Hawaiian volcanoes: From source to surface
Eleven slow slip events (SSEs) have occurred on the southern flank of Kilauea Volcano, Hawai’i, since 1997 through 2014. We analyze this series of SSEs in the context of Kilauea’s magma system to assess whether or not there are interactions between these tectonic events and eruptive/intrusive activity. Over time, SSEs...
Plethodon cinerius (eastern red-backed salamander) movement
Sean Sterrett, Adrianne B. Brand, William R. Fields, Rachel A. Katz, Evan H. Campbell Grant
2015, Herpetological Review (46) 71-71
Lungless salamanders (family Plethodontidae) are relatively sedentary and are presumed to have limited dispersal ability (Marsh et al. 2004. Ecology 85:3396–3405). Site fidelity in Plethodontidae is high, and individuals displaced 90 m return to home territories (Kleeberger and Werner 1982. Copeia 1982:409–415). Individuals defend territories (Jaeger et al. 1982. Anim....
Two magma bodies beneath the summit of Kilauea Volcano unveiled by isotopically distinct melt deliveries from the mantle
Aaron J. Pietruszka, Daniel E. Heaton, Jared P. Marske, Michael O. Garcia
2015, Earth and Planetary Science Letters (413) 90-100
The summit magma storage reservoir of Kīlauea Volcano is one of the most important components of the magmatic plumbing system of this frequently active basaltic shield-building volcano. Here we use new high-precision Pb isotopic analyses of Kīlauea summit lavas—from 1959 to the active Halema‘uma‘u lava lake—to infer the number, size,...

Elizabeth A. Sellers, David McCarthy
2015, Check List (11)
New collection records for Anthophorula micheneri (Timberlake, 1947) from Loudoun County and other locations in Virginia, USA document an approximately 1,350 km extension of its previously recorded geographic range. New state records for the rarely seen Hylaeus sparsus (Cresson, 1869) collected in Giles County and from a blue vane trap in Loudoun County, Virginia...

Tyler D. Johnson, Kenneth Belitz
2015, Journal of Hydrology: Regional Studies (3) 31-86
Study region California, USA. Study focus Identification of groundwater use is an important step in the regional-scale assessment of groundwater quality. In California, 1990 US Census data indicate that domestic wells provide drinking-water to about 1.2 million people. However, the location of these domestic well users of groundwater is...
Onset of rejuvenated-stage volcanism and the formation of Līhu‘e Basin: Kaua‘i events that occurred 3-4 million years ago
David R. Sherrod, Scot K. Izuka, Brian L. Cousens
Rebecca Carey, Valerie Cayol, Michael P. Poland, Dominique Weis, editor(s)
2015, Book chapter, Hawaiian volcanoes: From source to surface
For ocean-island volcanoes, an understanding of rejuvenated-stage volcanism requires knowing the age of onset, duration of the volcanic episode, and length of quiescence that preceded the rejuvenated pulse. On the Island of Kaua‘i, cuttings from two lava flows intercepted in the Hanamā‘ulu well (Līhu‘e basin) and assigned to the Kōloa...
Crustal stress and structure at Kīlauea Volcano inferred from seismic anisotropy
Jessica H. Johnson, Donald Swanson, Diana C. Roman, Michael P. Poland, Weston A. Thelen
Rebecca Carey, Valerie Cayol, Michael P. Poland, Dominique Weis, editor(s)
2015, Book chapter, Hawaiian volcanoes: From source to surface
Seismic anisotropy, measured through shear wave splitting (SWS) analysis, can be indicative of the state of stress in Earth's crust. Changes in SWS at Kīlauea Volcano, Hawai‘i, associated with the onset of summit eruptive activity in 2008 hint at the potential of the technique for tracking volcanic activity. To use...
Evidence for large compositional ranges in coeval melts erupted from Kīlauea's summit reservoir

Rebecca Carey, Valerie Cayol, Michael P. Poland, Dominique Weis, editor(s)
2015, Book chapter, Hawaiian volcanoes: From source to surface
Petrologic observations on Kīlauea's lavas include abundant microprobe analyses of glasses, which show the range of melts available in Kīlauea's summit reservoir over time. During the past two centuries, compositions of melts erupted within the caldera have been limited to MgO = 6.3–7.5 wt%. Extracaldera lavas of the 1959, 1971, and 1974 eruptions...

2015, Geomorphology (228) 765-786
A substantial increase in fluvial sediment supply relative to transport capacity causes complex, large-magnitude changes in river and floodplain morphology downstream. Although sedimentary and geomorphic responses to sediment pulses are a fundamental part of landscape evolution, few opportunities exist to quantify those processes over field scales. We investigated the downstream...

2015, Geomorphology (246) 649-668
Two dams on the Elwha River, Washington State, USA trapped over 20 million m3 of mud, sand, and gravel since 1927, reducing downstream sediment fluxes and contributing to erosion of the river's coastal delta. The removal of the Elwha and Glines Canyon dams, initiated in September 2011, induced massive increases in river sediment...
The 21 May 2014 Mw 5.9 Bay of Bengal earthquake: macroseismic data suggest a high‐stress‐drop event
Stacey Martin, Susan E. Hough
2015, Seismological Research Letters (86) 369-377
A modest but noteworthy Mw 5.9 earthquake occurred in the Bay of Bengal beneath the central Bengal fan at 21:51 Indian Standard Time (16:21 UTC) on 21 May 2014. Centered over 300 km from the eastern coastline of India (Fig. 1), it caused modest damage by virtue of its location and magnitude. However, shaking...

2015, Geosphere (11) 203-225
Widespread extension began across the northern and central Basin and Range Province at 17–16 Ma, contemporaneous with magmatism along the Nevada–Columbia Basin magmatic belt, a linear zone of dikes and volcanic centers that extends for >1000 km, from southern Nevada to the Columbia Basin of eastern Washington. This belt was...
