GEOLOGY AND EARTHQUAKE IMPACT IN JAMAICA
Note:See section 2.1.1 on seismicity and geological structure
The damage resulting from an earthquake in Jamaica is controlled by the site geology.
Two Geological Processes are Important:
1. Ground Amplification ( Ground Shaking) is a term which describes the actual trembling or jerking motion produced by the earthquake waves.
The site geology affects the degree of shaking in general. The severity of shaking is greater on sites underlined by unconsolidated sediments (e.g. Liguanea Plain) than sites on rocks (e.g. Red Hills).
2. Ground Failure includes all processes where ground fails in response to ground acceleration from an earthquake. Two processes have been identified:
