The short life of the volcanic island New Lateʻiki (Tonga) analyzed by multi-sensor remote sensing data

S. Plank, F. Marchese, et al.

This groundbreaking study by Simon Plank, Francesco Marchese, Nicola Genzano, Michael Nolde, and Sandro Martinis explores the October 2019 eruption of Late'iki Volcano in Tonga. The swift transformation of New Lateʻiki reveals a dramatic contrast with its predecessor, highlighting the rapid erosion of volcanic islands formed from easily erodible materials.

Abstract
This study investigates the October 2019 surtseyan eruption at Late'iki Volcano, Tonga, using multi-sensor remote sensing data (thermal, optical, and SAR). The eruption resulted in the collapse of an older island and the formation of New Lateʻiki, which eroded and was reclaimed by the ocean within two months. This contrasts with the 25-year lifespan of the 1995 island. The rapid erosion suggests New Lateʻiki was composed of easily erodible material like pyroclastic debris.
