Las viviendas subterráneas y el riesgo sísmico

It is estimated that underground dwellings throughout the world are home to between 40 and 60 million people. After a general analysis of the types of underground dwellings, their location and the factors influencing its development, analysis of the vulnerability of this type of housing has been introduced against natural risks, issue that has not been thoroughly studied before. It should be noted that the location of underground dwellings throughout the world matches in most cases with active regions seismically, so a first approach is carried out to the study of the vulnerability of underground dwellings compared to the seismic risk, having as background the earthquake in the Chinese region of Shaanxi occurred in 1556 that affect large groups of underground dwellings.
