The workshop will focus on two 4-hour sessions, aided by the methodologies and hardware from Reacción that we will provide. The first session will focus on elaborating a digital model of a section of Santiago and analyzing its risks. The second session will plan on designing how a community will react to natural disasters and use simple GPS-mapping to simulate a natural disaster and analyze the results of the plan made on the first session. We will look into moving into a real community in Santiago, or an outside environment to use the devices and make the simulation.
