15b comparing the characteristics of earthquakes, volcanoes and tsunamis (magnitude, speed of onset and areal extent, duration, frequency, spatial predictability) through hazard profiles hazard profiles - a diagram that shows the main characteristics of different types of tectonic hazards to allow easy comparison. Tectonic plates and plate boundaries the earth's outer shell, the lithosphere, consisting of the crust and uppermost mantle, is divided into a patchwork of large tectonic plates that move slowly relatively to each other. Plate tectonics is the theory that explains the global distribution of geological phenomena principally it refers to the movement and interaction of the earth's lithosphere this includes the formation, movement, collision and destruction of plates and the resulting geological events such as seismicity, volcanism, continental drift, and. The sparta fault, southern greece: tectonic geomorphology, seismic hazard mapping and conditional probabilities): the sparta fault system is a major structure approximately 64km long that bounds.
Vulnerability to natural hazards is thus the potential to be harmed by natural hazards some people and places are more vulnerable to certain hazards than other people and places while any one extreme event may be unusual, there are broad trends in natural hazards. The depth pattern of earthquakes can be used to determine which way the slab is inclined this area has the potential for large earthquakes the characteristics of s-waves include. Using a named location, explain how hydrometeorological hazards can contribute to a tectonic disaster•tectonic disaster is when a hazard event causes widespread disruption. Geomorphology (from ancient greek: γῆ, gê, earth μορφή, morphḗ, form and λόγος, lógos, study) is the scientific study of the origin and evolution of topographic and bathymetric features created by physical, chemical or biological processes operating at or near the earth's surface.
Discuss the view that the impact of earthquake hazards depends primarily on human factors 'tectonic hazard profiles determine the way in which people and. June 2010 'tectonic hazard profiles determine the way in which people and governments respond to hazards' discuss january 2011 explain why tectonic processes produce a variety of contrasting landscapes. Tectonic hazard profiles determine the way in which people and governments respond to hazards' discuss (total 70 marks) plan definition of tectonic hazard,. A tectonic shift in predicting earthquakes, volcanic hazards study of olivine, the main mineral found in the earth's mantle, provides new data for measuring earth's surface.
Hazard = some natural or human-induced process that has the potential to cause loss (human or infrastructure) seismic hazards = seismic ground shaking and tectonic deformation measured as magnitude and frequency at some specific location. Another key concept that will help determine if a hazard becomes a disaster is resilience this is the tectonic hazard profiles governance is the way a. Tectonic hazards 12 event profile of hazards, including frequency, magnitude, duration and areal extent 42 specific strategies involved in adjustment: modifying loss burden, modifying the event and modifying human vulnerability and the range of approaches and strategies used in locations at different stages of development. The mission of the washington geological survey is to collect, develop, use, distribute, and preserve geologic information to promote the safety, health, and welfare of the citizens, protect the environment, and support the economy of washington.
The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another divergent, where plates move apart and transform, where plates move sideways. They are a common way to compare and contrast different hazardsevent profiles event profiles can be drawn for any event and help illustrate the great variation in the nature of tectonic hazards the typical earthquake and volcanic profiles tend to differ most in terms of spatial predictability and frequency. 2 tectonic wedging theory tectonic wedging has been succinctly described by davis et al (1983): the overall mechanics of fold-and-thrust belts and accretionary wedges along compressive plate boundaries is considered to be analogous to that of a wedge soil or snow in front of a moving bulldozer.
Seismic hazard is the hazard associated with potential earthquakes in a particular area, and a seismic hazard map shows the relative hazards in different areas the maps are made by considering what we currently know about. 15 tectonic hazard profiles are important to an understanding of contrasting hazard impacts, vulnerability and resilience. 1) 'tectonic hazard profiles determine the way in which people and governments respond to hazards' discuss 2) 'approaches to managing cold environments are as varied as the environments themselves.
The latest in my volcano profiles series, this one on erta ale in ethiopia notable recent eruptions and history: an eruption of erta ale in 2005 forced evacuations of the region near the volcano. Given the current state of knowledge of seismic phenomena, little can be done to modify the hazard by controlling tectonic processes, but there are a variety of ways to control the risk or exposure to seismic hazards. The three major tectonic plates off the pacific northwest coast are undergoing a gradual shift, and the area in which they converge - popularly known as the triple junction - appears to be migrating in a southeasterly direction.
Calculate the estimated damages for each hazard event create a composite map of the risk assessment data that have been collected and mapped, and create a composite loss map. In the united states, the sierra nevada and baja california microplates have been distinguished this way geologic plate motions: present three different geologic methods help determine the trajectories of plates: paleomagnetic, geometric and seismic. Bethany mccay, university college london, the bartlett school of planing, graduate student 'tectonic hazard profiles determine the way in which people and.
