Late (Tonga)

The small, 6-km-wide circular island of Late, lying along the Tofua volcanic arc about 55 km WSW of the island of Vavaʻu, contains a 400-m-wide, 150-m-deep summit crater with an ephemeral lake.

A graben-like structure on the NE flank contains two large pit craters, the lower of which is partially filled by a saltwater lake.

Only two eruptions have occurred in historical time, both from NE-flank craters, which produced explosive activity and possible lava flows in 1790 and 1854.

It was discovered by Spanish naval officer Francisco Mourelle de la Rúa on 27 February 1781, on board of the frigate Princesa.
