The extensive harrat lava province of Arabia formed during the past 30 million years in response to Red Sea rifting and mantle upwelling. The area was regarded as seismically quiet, but between April and June 2009 a swarm of more than 30,000 earthquakes struck one of the lava fields in the province, Harrat Lunayyir, northwest Saudi Arabia. Concerned that larger damaging earthquakes might occur, the Saudi Arabian government evacuated 40,000 people from the region. Here we use geologic, geodetic and seismic data to show that the earthquake swarm resulted from magmatic dyke intrusion. We document a surface fault rupture that is 8 km long with 91 cm of offset. Surface deformation is best modelled by the shallow intrusion of a north-west trending dyke that is about 10 km long. Seismic waves generated during the earthquakes exhibit overlapping very low- and high-frequency components. We interpret the low frequencies to represent intrusion of magma and the high frequencies to represent fracturing of the crystalline basement rocks. Rather than extension being accommodated entirely by the central Red Sea rift axis, we suggest that the broad deformation observed in Harrat Lunayyir indicates that rift margins can remain as active sites of extension throughout rifting. Our analyses allowed us to forecast the likelihood of a future eruption or large earthquake in the region and informed the decisions made by the Saudi Arabian government to return the evacuees.

By contrast, burbot made a dramatic recovery in Lake Erie during 1993-2001 but declined during 2002-2007, due in part to a sharp decrease in recruitment. We used Akaike's Information Criterion to evaluate 129 linear regression models that included all combinations of one to seven ecological indices as predictors of burbot recruitment. Two models were substantially supported by the data: (i) the number of days in which water temperatures were within optimal ranges for burbot spawning and development combined with biomass of yearling and older (YAO) yellow perch Perca flavescens (Mitchill); and (ii) biomass of YAO yellow perch. Warmer winter water temperatures and increases in yellow perch biomass were associated with decreases in burbot recruitment. Continued warm winter water temperatures could result in declines in burbot recruitment, particularly in the southern part of the species' range. Published 2010.

Here, we study one such relatively small subduction zone by analysing the historical seismicity over the entire plate boundary region south of New Zealand, using these data to determine the seismic moment deficit of the subduction zone over the past ~100 yr. Our calculations indicate unreleased moment equivalent to a magnitude Mw 8.3 earthquake, suggesting this subduction zone has the potential to host a great, tsunamigenic event. We model this tsunami hazard and find that a tsunami caused by a great earthquake on the Puysegur subduction zone would pose threats to the coasts of southern and western South Island, New Zealand, Tasmania and southeastern Australia, nearly 2000 km distant.

Use of sediment sources from outside the area can result in sedimentary characteristics that differ from native sediments on the surface and at depth, altering conditions for both aeolian transport to dunes and interstitial fauna. Field data were gathered on an estuarine beach to determine differences in beach profile change, depth of sediment reworking, and potential for aeolian transport due to nourishment. Data were gathered over a 20-month period 6 months prior to nourishment, 3 days after nourishment, 6 months after nourishment, and 14 months after nourishment when the beach was mechanically graded to eliminate a vertical scarp in the foreshore. The nourishment consisted of 87,900m3 of sediment emplaced to create a 1.34-km-long, 30-m-wide berm 2.3m above mean tide level. Seven percent of the fill was removed from the profile within 6 months after nourishment, accompanied by 7m in horizontal retreat of the artificial berm. The fill on the backshore remained above the zone of wave influence over a winter storm season and was separated from the active foreshore by the scarp. Nourished sediments on the intertidal foreshore were significantly different from native sediments to a depth of 0.20m below the surface. A lag surface of coarse sediment formed by deflation on the backshore, resulting in a rate of aeolian transport <2% of the rate on the wave-reworked foreshore.Nourishing a beach to a level higher than would be created by natural processes can create a profile that compartmentalizes and restricts transport of sediment and movement of fauna between the foreshore and backshore. Mechanical grading can eliminate the scarp, allow for faunal interaction, and reestablish wave reworking of the backshore that will facilitate aeolian transport. Using an initial design to nourish the backshore at a lower elevation and allowing a dune to provide protection against flooding during major storms could prevent a scarp from forming and eliminate the need for follow-up grading. ?? 2010 Elsevier B.V.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Engineering","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.ecoleng.2010.07.016","issn":"09258574","usgsCitation":"Jackson, N., Nordstrom, K., Saini, S., and Smith, D., 2010, Effects of nourishment on the form and function of an estuarine beach: Ecological Engineering, v. 36, no. 12, p. 1709-1718, https://doi.org/10.1016/j.ecoleng.2010.07.016.","startPage":"1709","endPage":"1718","numberOfPages":"10","costCenters":[],"links":[{"id":218555,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.ecoleng.2010.07.016"},{"id":246577,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"36","issue":"12","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a076ce4b0c8380cd516be","contributors":{"authors":[{"text":"Jackson, N.L.","contributorId":104189,"corporation":false,"usgs":true,"family":"Jackson","given":"N.L.","email":"","affiliations":[],"preferred":false,"id":455762,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nordstrom, K.F.","contributorId":17733,"corporation":false,"usgs":true,"family":"Nordstrom","given":"K.F.","email":"","affiliations":[],"preferred":false,"id":455760,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Saini, S.","contributorId":7953,"corporation":false,"usgs":true,"family":"Saini","given":"S.","email":"","affiliations":[],"preferred":false,"id":455759,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Smith, D.

A 3-a study of inorganic Hg (IHg) and methylmercury (MeHg) was conducted in physical media (soil, sediment, surface water, porewater and soil/sediment extracts) to identify non-point sources, transport mechanisms, and potential controls on Hg(II)-methylation. Data collected from surface water and sediment indicate that the majority of the non-point sources of IHg to the South River are within the first 14. km downstream from the historic point source. Partitioning data indicate that particle bound IHg is introduced in this reach, releasing dissolved and colloidal bound IHg, which is transported downstream. Extraction experiments revealed that floodplain soils released a higher fraction of their IHg content in aqueous extractions than fine-grained sediment (FGS). Based on ultrafiltration [<5000 nominal molecular weight cutoff (NMWC)] the majority of soil IHg released was colloidal in nature, providing evidence for the continued evolution of IHg for Hg(II)-methylation from soil. Strong seasonal patterns in MeHg concentrations were observed in surface water and sediment. The highest concentrations of MeHg in surface water were observed at moderate temperatures, suggesting that other factors limit net Hg(II)-methylation. Seasonal changes in sediment organic content and the fraction of 1. N KOH-extractable THg were also observed and may be important factors in controlling net Hg(II)-methylation rates. Sulfate concentrations in surface water are low and the evidence suggests that Fe reduction may be an important Hg(II)-methylation process. The highest sediment MeHg concentrations were observed in habitats with large amounts of FGS, which are more prevalent in the upper half of the study area due to the lower hydrologic gradient and agricultural impacts. Past and present land use practices and other geomorphologic controls contribute to the erosion of banks and accumulation of fine-grained sediment in this section of the river, acting as sources of IHg. ?? 2010 Elsevier Ltd.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Applied Geochemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.apgeochem.2010.09.004","issn":"08832927","usgsCitation":"Flanders, J., Turner, R., Morrison, T., Jensen, R., Pizzuto, J., Skalak, K., and Stahl, R., 2010, Distribution, behavior, and transport of inorganic and methylmercury in a high gradient stream: Applied Geochemistry, v. 25, no. 11, p. 1756-1769, https://doi.org/10.1016/j.apgeochem.2010.09.004.","startPage":"1756","endPage":"1769","numberOfPages":"14","costCenters":[],"links":[{"id":218581,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.apgeochem.2010.09.004"},{"id":246606,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"25","issue":"11","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a031ce4b0c8380cd50346","contributors":{"authors":[{"text":"Flanders, J.R.","contributorId":87401,"corporation":false,"usgs":true,"family":"Flanders","given":"J.R.","email":"","affiliations":[],"preferred":false,"id":455768,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Turner, R.R.","contributorId":29983,"corporation":false,"usgs":true,"family":"Turner","given":"R.R.","email":"","affiliations":[],"preferred":false,"id":455764,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Morrison, T.","contributorId":90966,"corporation":false,"usgs":true,"family":"Morrison","given":"T.","affiliations":[],"preferred":false,"id":455769,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Jensen, R.","contributorId":58877,"corporation":false,"usgs":true,"family":"Jensen","given":"R.","affiliations":[],"preferred":false,"id":455766,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Pizzuto, J.","contributorId":32381,"corporation":false,"usgs":true,"family":"Pizzuto","given":"J.","email":"","affiliations":[],"preferred":false,"id":455765,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Skalak, K.","contributorId":22997,"corporation":false,"usgs":true,"family":"Skalak","given":"K.","affiliations":[],"preferred":false,"id":455763,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Stahl, R.","contributorId":60888,"corporation":false,"usgs":true,"family":"Stahl","given":"R.","email":"","affiliations":[],"preferred":false,"id":455767,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}} ,{"id":70036399,"text":"70036399 - 2010 - Predicted and observed spectral response from collocated shallow, active- and passive- source Vs data at five ANSS sites, Illinois and Indiana, USA","interactions":[],"lastModifiedDate":"2012-03-12T17:22:01","indexId":"70036399","displayToPublicDate":"2010-01-01T00:00:00","publicationYear":"2010","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3372,"text":"Seismological Research Letters","onlineIssn":"1938-2057","printIssn":"0895-0695","active":true,"publicationSubtype":{"id":10}},"title":"Predicted and observed spectral response from collocated shallow, active- and passive- source Vs data at five ANSS sites, Illinois and Indiana, USA","docAbstract":"[No abstract available]","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Seismological Research Letters","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1785/gssrl.81.6.955","issn":"08950695","usgsCitation":"Odum, J.K., Stephenson, W.J., and Williams, R.A., 2010, Predicted and observed spectral response from collocated shallow, active- and passive- source Vs data at five ANSS sites, Illinois and Indiana, USA: Seismological Research Letters, v. 81, no. 6, p. 955-964, https://doi.org/10.1785/gssrl.81.6.955.","startPage":"955","endPage":"964","numberOfPages":"10","costCenters":[],"links":[{"id":218499,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/gssrl.81.6.955"},{"id":246516,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"81","issue":"6","noUsgsAuthors":false,"publicationDate":"2010-11-15","publicationStatus":"PW","scienceBaseUri":"505a818ce4b0c8380cd7b5b1","contributors":{"authors":[{"text":"Odum, J.
