Description

From Wood and Kienle (1990) [1] : "Segula volcano is built upon a 100-m-deep marine platform by the accumulation of flows and pyroclastic material emanating from a single center. Although there are no dated eruptions, some flows and pyroclastic deposits are so little weathered that ages of only a few hundred years are estimated. Pyroclastic material covers much of the cone's surface and a cinder cone resides in the middle of the summit crater."

Name Origin

"Segula Peak" was published on a 1951 U.S. Geological Survey map. W.H. Nelson (1959) called it "Segula Volcano" (Orth, 1971).
