Samoan volcanism is tectonically controlled and is generated by tension-stress activities associated with the sharp bend in the Pacific Plate (Northern Terminus) at the Tonga Trench. The Samoan island chain dominated by a mixture of shield and post-erosional volcanism activities. The closed basin structures of volcanoes such as the Crater Lake Lanoto enable the entrapment and retention of a near-complete sedimentary record, itself recording its eruptive history. Crater Lanoto is characterised as a compound monogenetic and short-term volcano. The book is attempted to link the new information for Crater Lanoto volcano to the structures of the region and larger scale shield and post-erosional activities. There is a focus on current records which are used as a guideline to correlate with those of a similar volcanic nature, along the Samoan Volcanic Field. More importantly, the records will improve understanding, about the relationship between the volcanism of Samoa and regional tectonic processes. The research presents the summary of new research findings that would improve our understanding and knowledge in volcanism process along the Samoa Volcanic Field.
