Risk Assessment of Introduced Fish Species as a Biodiversity Mitigation Effort in Lake Toba, North Sumatra, Indonesia

Zoodiversity
Lake Toba's environment and ichthyofauna are degrading due to human activities and the introduction of invasive fish species. Studies are needed to identify species, distribution patterns, densities and risks of introduced fish species, and these studies

Melt re-injection into large magma reservoir after giant caldera eruption at Kikai Caldera Volcano

Communications Earth & Environment
Melt re-injection after a giant caldera eruption was quantitatively investigated for the Kikai Caldera Volcano in Japan, which erupted 7300 years ago (Kikai-Akahoya eruption). Our seismic refraction survey revealed a low-velocity anomaly directly beneath

Submarine cores record magma evolution toward a catastrophic eruption at Kikai Caldera

Communications Earth & Environment
Magma evolution toward a caldera-forming eruption remains uncertain in many cases owing to the lack of successive volcanic records before catastrophic eruptions.
