We've asked around - no one
seems to know if the 1924 or
1998 events caused tsunamis.
We have been told that the
Balleny hotspot has produced
the Balleny Islands  extending
from 66°15' to 67°35'S and 162°
30' to 165°00'E. The islands are
heavily glaciated and are of
volcanic origin - the major
islands of Young, Buckle and
Sturge are all stratovolcanos.
Nevertheless, the dogma is only
tremors of moderate strength:
mostly near  the Pacific–
Antarctic Ridge, Macquarie
Triple Junction and Pacific
Rim.
