For 40 years, the Biological Survey of Canada (BSC) has encouraged and organised studies of the arthropod fauna of Canada, through the wide involvement of the scientific community and the leadership of an expert steering committee. The benefits of the BSC to science include the completion of major cooperative projects to acquire and synthesise knowledge (documenting faunas in the Yukon, Canadian grasslands, and other significant regions and habitats), the assembly and organisation of information and specimens, and improved communication among entomologists. Its efforts have led to valuable monographs, scientific briefs, newsletters, and other products summarised here, including documents that are also useful to...

0.2-second spectral response acceleration (5% of critical damping) with a 1% probability of exceedance in 1 year for the Western United States
This data set represents the results of calculations of hazard curves for a grid of points with a spacing of 0.05 degrees in latitude and longitude. This particular data set is for horizontal spectral response acceleration for 0.2-second period with a 1 percent probability of exceedance in 1 year. The data are for the Western United States and are based on the long-term 2014 National Seismic Hazard Model.
The Gazli cluster is named for the town of Gazli in northwest Uzbekistan. The source region was nearly aseismic until April 8, 1976 when a large (Ms 7.0) earthquake initiated several years of very active seismicity, including another Ms 7.0 event in May 1976 and a third Ms 7.0 event in March 1984. Low-level activity continues currently. It is generally believed that the sequence represents an episode of induced seismicity related to large-scale gas extraction industry in the area. The cluster is formed mainly from events that have depth control from teleseismic relative depth phases, plus one event, on June 25, 1991, that was recorded by a temporary seismic network (operated by LGIT, Grenoble, France) and was well-enough...
