St. Paul island rises 268m above the Indian Ocean .
In 1793 smoke and fresh ash were observed on a parasitic cone
near the southwest corner of the island.
Fumaroles have been evident for the succeeding two centuries.
Older volcanics represented by tholeiitic palagonite tuffs
cut by dikes and a comendite intrusion
are exposed by faults on the northeastern flanks of a younger
volcano.
The younger stratovolcano is composed of numerous thin lava
flows interlayed with scoria and cinders.
Peripheral scoria cones are aligned along radial fissures.
These younger flows are aluminous tholeiite with an age of
0.5 to 0.04 Ma.
