Event response pages are a service to help coordinate community science after an earthquake or other notable geophysical event by collecting relevant data. Findings and figures are preliminary and subject to revision.
At 7:42:46 UTC on April 21, a magnitude 6.7 earthquake occurred offshore of Nicaragua 58 kilometers southwest of Masachapa. For more information, see the USGS Earthquake Hazards Program event page.
The event occurred within the footprint of the Network of the Americas (NOTA), a network of continuous GPS/GNSS stations and borehole instruments operated by UNAVCO that monitors plate motion and transient deformation, in addition to other applications. Stations near the event for which UNAVCO provides data includes NOTA, PI, and external contributor stations. Stations in Costa Rica are operated in collaboration with OVSICORI. UNAVCO support for these sites comes through a combination of NOTA and a Telica Volcano PI project (NSF award 0911546). Stations in Nicaragua are funded through NOTA and a PI project focused on the Nicoya Peninsula, with additional support by the Nicaraguan Institute for Territorial Studies (INETER). NOTA sites in Honduras benefit from collaboration with El Instituto de la Propriedad de Honduras.
These data are provided by the Geodetic Facility for the Advancement of Geoscience (GAGE) Facility, operated by UNAVCO, Inc. with support from the National Science Foundation and the National Aeronautics and Space Administration under NSF Cooperative Agreement EAR-1724794. NOTA is a core component of the NSF GAGE Facility. To acknowledge use of these data please follow the acknowledgment guidelines.
