Message from Dani Coleman, Director of Hazard Management Cayman Islands. An All Clear has been issued for the Cayman Islands following the tsunami threat that went into effect shortly after the 7.5-magnitude earthquake which was detected 202 km southwest of George Town, Grand Cayman. This was a significant earthquake, and we are very thankful that no major damage has been reported on our islands. We have no doubt that there will be aftershocks over the next couple of days so we ask the public to remain vigilant and keep abreast to all official channels.
