Trans-Haiti: Crustal-scale geodynamics of the Hispaniola plate boundary in the Caribbean
This is a Full Scientific Report resulting from NERC Geophysical Equipment Facility Loan 987, principal investigator Dr Derek Keir.

Abstract

SEIS-UK provided a loan of 23 broadband seismic systems (11 40TD and 12 6TD) for deployment in Haiti, from April 2013 until June 2014. The University Paris VI provided an additional 4 Reftek40T broadband seismic stations deployed for the same period of time. These systems recorded continuously at 100 samples per second, with relatively minor data losses due to equipment problems. The dataset collected has been archived via SEIS-UK with IRIS (Incorporated Research Institutions for Seismology). Records of teleseisms have been processed and receiver functions have been computed to reveal the structure of the crust as part of a PhD study in Paris VI University by Jordane Corbeau. Further processing for surface wave tomography using fast anisotropy directions obtained from SKS wave arrivals to reveal the signature of lithospheric deformation will be performed during a NERC oil and gas cdt funded PhD at the University of Southampton. Local earthquakes were also recorded during the TRANS-HAITI project and the location of the microseismicity is still in progress. In addition, SEIS-UK provided a loan of 10 geophones in November 2013 for a short active source experiment.
