UNAVCO Response

GPS Data
UNAVCO downloaded high-rate 1-sps (1 Hz) and 5-sps (5 Hz) GPS/GNSS data from 18 stations and 1-sps (1 Hz) data only from an additional three stations in response to the M7.5 earthquake 44km E of Great Swan Island, Honduras, on 2017-01-10 (Figure 2). Stations downloaded include 14 COCONet stations and additional stations operated by OVSICORI, within 1000 km of the earthquake's epicenter. Date were downloaded for a ±3-hour period around the event (7 hours total, from 23:00 - 05:59 UTC). These data are available from the UNAVCO high rate data page. Note: Six of these stations stream data in real time: TGMX, UNPM, CN23, CN30, CN12, and SSIA; to request access to these and other RT-GPS stations operated by UNAVCO please send an email request to rtgpsunavco.org.

As part of this response, UNAVCO and partners reestablished communications to several COCONet stations and are prepared to send a field engineer to COCONet station CN18 on Swan Island if the Honduran navy is unable to repair the station onsite.
