The above are in-house publications of earthquakes located and extra-regional phase data recorded by the Jamaica Seismograph Network. Each issue includes a preface, acknowledgements and four sections. Section A is a documented introduction to the Jamaica Seismograph Network, with maps and a bibliography. Each annual volume has three sections: B, which lists all earthquakes located with phase readings and provides epicentral maps; C, which contains lists of all earthquakes felt on Jamaica and maps of intensities when there is sufficient information; and D, an illustrated summary of each year’s seismicity, including b-value plots. The issues have been distributed to national and parish libraries and libraries of other prominent organizations (total distribution about 30 copies of each issue).
