On 9 January 2018, at approximately 8:51 p.m. local time (02:51 10 January UTC), a magnitude 7.5 earthquake struck in the Yucatán Basin of the Caribbean Sea, 44 kilometres (27 mi) east of Great Swan Island off the coast of Honduras.[1] The earthquake was felt across Central America, and rattled windows in Tegucigalpa.[2]
Tsunami advisories were issued for certain areas by the U.S. Tsunami Warning Center. They were later cancelled after further monitoring.[3] No tsunami was generated since the earthquake was an almost pure strike-slip on a near vertical plane, producing little upward movement of the sea floor that would cause a large displacement of water.[4]
Earthquake
The earthquake occurred at a depth of around 10 kilometres (6.2 mi) on a transform fault zone known as the Swan Islands Transform Fault in the Cayman Trough, where it forms part of the boundary between the North American Plate and the Caribbean Plate.[1] The area just to the west also produced a large earthquake in 2009 that measured 7.3 on the moment magnitude scale.[5]
