Following the Chile earthquake of February 27, 2010, funding was provided by the NSF RAPID response mechanism to install 58 portable PASSCAL/USArray stations for five month’s observations of aftershocks. Arrangements have been made to share data from similar stations installed by Chilean, French, German, and British investigators (map on right). An NSF/MRI proposal from IRIS has recently been funded to work with the University of Chile to install 10 global reporting geophysical observatories (map on left), with seismic, infrasound and meteorological instruments, as a backbone network within the planned Chilean National Seismic Network. These collaborations in data exchange and network development can form a model for future efforts in International Development Seismology.</p>
