The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title. Additional discussion of data sources can be found under Volcano Data Criteria.

Acoustic signals (T-waves) from a seismic swarm were detected in 1990 from a source along the Udintsev fracture zone, near its intersection with the Pacific-Antarctic Rise (Global Volcanism Network Bulletin). The seismicity may have been linked to volcanic activity.
