Geologic Background:
The ephemeral Falcon Island, named after the
H.M.S. Falcon, which reported a shoal in 1865, has been
the site of island-forming eruptions on at least two
occasions since the 19th century.
Historic Activity:
- At least 11 eruptions since 1781.
- Islands up to 6 km in length were formed in eruptions
beginning in 1885 and 1927. Passing ships often reported
"smoke" issuing from the site of Falcon Island.
- The latest explosive eruptions were reported in 1936.
- By 1949 the island had eroded beneath sea level.
- An eruption of uncertain location (may have been
Falcon Island) occurred in 1970.
