The damage of buildings and manmade structures, where most of human activities occur, is the major cause of casualties of from earthquakes. In this paper, an improved technique, Earthquake Damage Visualization (EDV) is presented for the rapid detection of earthquake damage using the Synthetic Aperture Radar (SAR) data. The EDV is based on the pre-seismic and co-seismic coherence change method. ...

Automated earthquake damage assessment from post-event only remotely sensed data is highly desirable, especially when new generation, Very High Resolution (VHR) spaceborne data is concerned, lacking extensive pre-event archives. Though, most damage assessment method either rely on human interpretation or on pre-post-event comparison. In this paper we illustrate some possible tracks for investig...

The building damage assessment is a very important task after a strong earthquake. For taking decisions about the building habitability and reparability it is necessary evaluate the building damage, but the expert professionals are insufficient, and therefore voluntary non-experts professionals must be including in the task. This personnel type displays the tendency to aggravate or to underesti...

introduction vulnerability is a term used to show the amount and extent of damage and the losses caused by natural disasters in different communities (social, formal-physical, etc.). vulnerabilities is identified as the sensitivity of the environment against the hazards. from among natural disasters, earthquakes can have a vast scope of losses for desert regions. therefore, in order to reduce a...

Significant damage of transportation infrastructure systems usually occurs during a major earthquake event. The impacts of bridge damage include not only short-term costs of structural repair, but also long-term economic consequences. In addition to initial replacement or repair costs of damage to the transportation structures, large earthquakes increase delays because of network components sev...

The ShakeOut Scenario assessed earth-science impacts, physical damage, and socioeconomic impacts of a hypothetical M7.8 southern San Andreas Fault earthquake. Among many detailed studies were special studies of 12 lifelines, 7 of which were performed by panels of employees of the utilities at risk. Panels met for four hours. Panelists were presented with the scenario’s earth science impacts and...

Earthquake-induced ground failure, in the form of liquefaction or slope instability, manifests itself as permanent ground deformation (PGD), which can cause significant damage to buildings and infrastructure. Current methodologies for the evaluation of ground failure related earthquake losses are considerably less advanced than those for ground shaking. Most existing damage scales do not incorp...

The moderate magnitude Chamoli earthquake, which occurred on 29 March, 1999 in the Alkananda river valley region of Garhwal Himalaya, caused considerable loss to human life and property. From a systematic ®eld survey of the damage, conducted for ®ve continuous days immediately after the earthquake, the following could be noted: (i) The consequences of the damage are most pronounced near the Mai...

by identifying the damage index of a structure, in addition to a correct understanding from real behavior of the structure, the required criterion for strengthening would be given. researchers have given many relations for determination of damage index but such relations have been based upon laboratory methods which challenge their usage in a broad term. in this paper two new methods are given ...

We describe a multidisciplinary and interdisciplinary method to analyse the causes of differential macroseismic effects caused by an earthquake in a historical town. We illustrate the method with a case study based on analysing the damage caused by the 1930 Irpinia earthquake (Me=6.7) in Melfi, a town in southern Italy. A damage pattern map was already available for this site. To understand the...
