Abstract

Providing avatar support for trapped seismic event survivors is provided. A survivor is detected in debris of a collapsed structure using a set of sensors. An avatar communicates with the survivor. Fresh air flow drawn from different directions is measured to detect a pathway through the debris to an environment outside the collapsed structure. The pathway is detected through the debris to the environment outside the collapsed structure based on measuring the fresh air flow drawn from the different directions.
