Geography
In May 2000, an international research team aboard the CSIRO research vessel FRANKLIN fixed the position of the volcano at 8° 59.65'S, 157° 58.23'E. At that time the vent of the volcano was below sea level, but frequent eruptions ejected molten lava up to 70 m (230 ft)
Eruptions
When the volcano erupted in 2003, a 15 m-high (49 ft) island formed above the surface, but it disappeared soon after. Additional eruptive activity was observed and reported in March 2004 and April 2007.[5][6] More recent volcanic activity can be inferred from observations of discolored water around the volcano, in 2020 and January 2021.[1]
Marine life
In 2015, marine wildlife was found living inside Kavachi's crater, including the scalloped hammerhead, the silky shark, and the sixgill stingray.[7]
It has subsequently been given the nickname "Sharkcano" by various media outlets.[8][9][10]
