LOCATION OF JAMAICA
The Earthquake Unit
MISSION STATEMENT
Through operating the Jamaica Seismograph Network
and affiliating with other Caribbean and Regional
Networks the Earthquake Unit seeks to understand
earthquake processes in and around Jamaica and advise
the society about earthquake hazard thereby
encouraging community awareness and the application
of mitigative strategies to development.

Work of the Earthquake Unit
• The Unit operates the Jamaica Seismograph
Network, Jamaica Strong Motion Network and
the GPS Monitoring Network.
• Archives and records all earthquake related data
for Jamaica.
• Collaborates/conducts relative research on
Jamaica seismicity and tectonics.
• Performs national and site specific seismic hazard
assessment for national and private entities.
Earthquake Unit contd.
• Informs the public about felt earthquake and
conduct awareness campaign. Provides
bulletin to the Office of Disaster Preparedness
and Emergency management (ODPEM) and the
media after felt earthquake.
• Operates the National Data Centre (NDC) for
Jamaica in keeping with the CTBTO
• Hosts tours by schools and other community
groups at the Central Recording Station.

PLANS FOR THE NETWORK FOR THE
NEXT 3 YEARS
• Upgrade all the short period stations to digital
broadband using Guralp instruments (total 8).
• Expand the strong motion accelerograph
network by adding 40 accelerographs.
• To improve and expand the data
communication network.
• Aquire geophysical equipment for seismic
surveys and microzonation studies
