GIS as a Tool for Assessing Volcanic Hazards, Vulnerability, and at Risk Areas of the Three Sisters Volcanic Region, Oregon
نویسنده
چکیده
Active volcanoes give significant threats to the populations that live in their proximity. The Three Sisters Volcanic region is one of 9 threatening volcanoes within the Cascades volcanic arc. Eruptions are probable which makes it essential to complete hazard, vulnerability, and risk assessments so that proper planning, education and mitigation procedures can be implemented prior to the threat occurring. GIS provides a tool for extending hazard and vulnerability mapping to assist in the analysis of risk. Creating a procedure using GIS as an aid helps in automating the very complicated and lengthy processes of establishing a risk assessment. Responses to volcanic events can be better handled with an understanding of how communities will be affected.

Magmatic activity beneath the quiescent Three Sisters volcanic center, central Oregon Cascade Range, USA
[1] Images from satellite interferometric synthetic aperture radar (InSAR) reveal uplift of a broad 10 km by 20 km area in the Three Sisters volcanic center of the central Oregon Cascade Range, 130 km south of Mt. St. Helens. The last eruption in the volcanic center occurred 1500 years ago. Multiple satellite images from 1992 through 2000 indicate that most if not all of 100 mm of observed upli...

Damavand is a large dormant stratovolcano in the Alborz Mountains of northern Iran located in one of the most populous provinces, which could be adversely affected by tephra fall from Damavand. The youngest known eruption is a lava flow on the western flanks with an age of 7.3 ka. The volcanic products are predominantly porphyritic trachyandesite. Three major young pumice deposits, named here a...
متن کاملThe Volcanic Hazards Assessment Support System for the Online Hazard Assessment and Risk Mitigation of Quaternary Volcanoes in the World
Volcanic hazards assessment tools are essential for risk mitigation of volcanic activities. A number of offline volcanic hazard assessment tools have been provided, but in most cases, they require relatively complex installation procedure and usage. This situation causes limited usage of volcanic hazard assessment tools among volcanologists and volcanic hazards communities. In addition, volcani...

A multi-hazard, multi-vulnerability impact model has been developed for application to European volcanoes that could significantly damage human settlements. This impact model is based on volcanological analyses of the potential hazards and hazard intensities coupled with engineering analyses of the vulnerability to these hazards of residential buildings in four European locations threatened by ...
متن کاملThe PREVIEW Global Risk Data Platform: a geoportal to serve and share global data on risk to natural hazards
With growing world population and concentration in urban and coastal areas, the exposure to natural hazards is increasing and results in higher risk of human and economic losses. Improving the identification of areas, population and assets potentially exposed to natural hazards is essential to reduce the consequences of such events. Disaster risk is a function of hazard, exposure and vulnerabil...
