After a powerful 8.8 earthquake hit Chile on the morning of February 27, 2010, President Michele Bachelet declared a “state of catastrophe” as buildings and electricity were struck down. The epicenter of the quake was 70 miles from Concepcion, the second-largest city with more than 200,000 residents. The earthquake also set off tsunami warnings for the rest of the South and North American coasts, also encompassing the state of Hawaii. As relief teams and troops continue to search for survivors and restore order in Chile, aftershocks were also reported.
ESRI, Google, and other mapping tools have created their own outlets of the response efforts to help Chile. Google has created resources on their Lat Long Blog featuring “Person Finder” and options to access and contribute data about Chile. ESRI’s ArcGIS Online has provided several layers and web maps on the Chile Earthquake on the ArcGIS Online website. These features include the magnitudes and locations of the earthquake and its aftershocks, tsunami travel time, South American geology, and vulnerability maps.
