Relative Motion between St. Croix and the Puerto Rico-Northern Virgin Islands Block Derived from Continuous GPS Observations (1995–2014)

Figure 7

Velocity vectors of permanent GPS stations (>5 years) within the PRVI and Lesser Antilles region. The vectors are referred to the SPRNVIRF. The boundary between the Lesser Antilles inner forearc and outer forearc is plotted with a dark dashed line. The small pink dots represent earthquakes (1900–2014) with magnitudes between 4 and 5 (); the big pink dots represent earthquakes (1900–2014) with magnitudes larger than 5.0 (). Earthquake epicenter and magnitude information is obtained from the U.S. Geological Survey Advanced National Seismic System (ANSS) Comprehensive Catalog (http://earthquake.usgs.gov/earthquakes/search/).
