Additional Physical Format: Online version: Stevens, Anne E. Seismic risk in the northern Yukon and adjacent areas. [Ottawa]: Environmental-Social Committee, Northern Pipelines, Task Force on Northern Oil Development, The level of earthquake risk is divided into several zones. Despite the large number of active faults in New Zealand, some regions are more prone to earthquakes than others.

An iso-seismal map is used to determine the hazard for a particular location in the seismic design standard that engineers use. To simplify the design and construction of. Such large “characteristic” earthquakes may have recurrence times that are very long, such that none have occurred in the period of earthquake monitoring.

We provide a description of the regional seismicity and hazard for all of the Yukon and adjacent areas, but with focus on the northern Yukon-Beaufort-Mackenzie region. Figure 2. Yukon, Canada has had: (M or greater) 0 earthquakes in the past 24 hours 0 earthquakes in the past 7 days; 2 earthquakes in the past 30 days; 65 earthquakes in the past days.

The induced or passive nature of seismic activity in this region appears to be attributed a discharge in the weakened lithoshperic sites of tectonic stresses generated in the zone of the Central Laptev Sea rifting.

The deep structure of the archipelago and adjacent areas has been estimated from the evidence on distant earthquakes (Avetisov,a). If seismic risk is t aken as the produ ct of seismic haz ard, probability of rockburst damage and exposure, then: seismic risk = (seism ic hazard) x (prob ability of rock mas s damage) x (exposu re).

The Biggest Earthquakes in Yukon, Canada. Yukon, Canada has had: (M or greater) 0 earthquakes in the past 24 hours 0 earthquakes in the past 7 days.

seismic risk mitigation policies and response plans. • To promote public education on seismic-risk mitigation, members developed a two-day public training course on Post-Earthquake Safety Assessment of Facilities. Approximately people were trained in and the Commission will continue to offer at least two classes per year.

Earthquake Monitoring and Earthquake Catalogue Instrumental monitoring of earthquakes in western Canada began with the first seismograph in Victoria in However, only the very largest events could be located until.

Abstract. The problem of assessing seismic hazard in low-seismicity areas becomes obvious in many practical applications. A typical low-seismicity area, which experienced damaging earthquakes in historical times, is the North German Plain, for which a case study is by: 6.

Floor live load. The uniformly distributed, concentrated and impact floor live load used in the design shall be indicated for floor areas. Use of live load reduction in accordance with Section shall be indicated for each type of live load used in the design.

Roof live load. The roof live load used in the design shall be indicated for roof areas (Section ). A survey was conducted of underground, mechanized hardrock mines to investigate the prevalence and consequences of seismic risk. The survey Author: Marty Hudyma.

fieldwork and preliminary interpretation of seismic data. Structural Geology The southern Peel Plateau and Plain region marks a profound change in structural style from broad anticlines with intervening narrow synclines in the northern Mackenzie Mountains, to linear and narrow ridges in the northern Franklin Mountains to the east-northeast.

Alaska seismic & Environmental, LLC ASE is committed to providing high quality monitoring and consulting for blasting and other vibration producing construction projects. ASE and our associates have extensive experience measuring ground vibrations from a variety of sources from blasting to pile driving, rock hammering, aggregate excavation, and.

The Workshop on the Seismicity and Seismic Risk in the Off­ shore North Sea Area was intended to bring together experts from a variety of disciplines as well as interest groups with involve­ ment in siting, design and construction of offshore structures in the region.

earthquake hazard, the seismic risk increases in older neighborhoods characterized by important concentration of buildings constructed prior to the introduction of seismic design provisions.

Unreinforced masonry buildings represent a significant portion among those pre-code constructions (Abo-El-Ezz et al., ). Such is the case. Seismic Safety Products manufactures and sales the Northridge earthquake actuated natural gas and propane shutoff valve that prevents fires and explosions caused by.

When an earthquake occurs, there is very little time to think or to act. Yukon schoolchildren, like students in British Columbia and California, learn the basic life-saving steps known as drop, cover, and hold on.

Regular earthquake drills in Yukon schools reinforce these steps. When earthquake shaking begins: Size: 1MB. This report provides an assessment of the seismic hazard for the area of the proposed basalt quarry and marine terminal on Digby Neck as well as the regional and local distribution of faults and earthquakes.

Within Canada, the Bay of Fundy area occurs within the Northern Appalachian Seismic Zone (NAN). Figure 1 below shows the. Do you know what seismic risk is, and the factors that are used to determine seismic risk. -seismic risk-describes the damage that can be expected over the long term in a specified region -seismic hazard-frequency and intensity of earthquake shaking and ground disruption that can be expected over the long term at some specified location.

areas of petroleum exploration in the Northwest Territories and northern Yukon (Fig. Although never intended for the uses to which they are now being applied, the seismic shothole drillers’ log records provide an immense new resource of baseline, near-surface ( m), lithostratigraphic geoscience data, contributing both.

The volcanic history of the Northern Cordilleran Volcanic Province presents a record of volcanic activity in northwestern British Columbia, central Yukon and the U.S. state of easternmost volcanic activity lies in the northern part of the Western Cordillera of the Pacific Northwest region of North America.

Extensional cracking of the North American Plate in this part of North. The threat of seismic damage is low in the Prairie Provinces, south-western and northern Ontario, but some risk is evident. There are regions in northern Canada where seismic risk is moderate-to-high, although fewer people and buildings are located in these areas.

Hazard Zones show areas of equal risk of damage to a particular structure. Introduction. Seismic lines, narrow linear clearings created during hydrocarbon exploration, are a common feature in the hydrocarbon-rich boreal and tundra ecosystems of North America ().As ofTimoney and Lee () estimated that the total length of seismic lines in Alberta, Canada, alone was – million km, while Lee and Boutin () noted that in northeastern Alberta, the Cited by:   Backgrounder on Seismic Reviews at U.S.

Nuclear Power Plants Printable Version Regulating for Mother Nature (video) Every U.S. nuclear power plant, even in areas with minimal seismic activity, is designed and built to withstand earthquakes and other natural hazards.

The Seismic Safety Commission was established by the legislature in as a state agency to advise the governor, the legislature, and the public on ways to reduce earthquake risk.

The commission manages the California Earthquake Hazard Reduction Program and reviews earthquake-related activities funded by the state. John W.

Flood, fire, blizzards, and ice storms are among the major natural disasters having an impact on the built environment in Canada. Among the least-discussed, and most misunderstood, are seismic events.

Yes, there are regular earthquakes in this country, and, yes, they can be significant enough to have negative effects on buildings and occupants. The Alaska Earthquake and Tsunami Hazards team conducts field-based research to understand how, where, and why earthquakes and tsunamis occur in Alaska.

Our research examines earthquake hazards that contribute to societal risk in Alaska and beyond, including earthquake ground motion, fault slip, surface deformation, landslides and liquefaction.
