Exposure to environmental hazards is an important determinant of health, and the frequency and severity of exposures is expected to be impacted by climate change. Through a partnership with the U.S.

The main island, Tongatapu, suffered waves up to 17 m, and Tofua Island suffered waves up to 45 m, comfortably placing HTHH in the "megatsunami" league. We present a tsunami simulation of the Tongan Archipelago calibrated by field observations, drone, and satellite data.

- The island of Hunga Tonga Hunga Ha'apai (HTHH) was created by volcanic eruptions and existed for 7 years before a significant eruption destroyed it on January 15, 2022, providing a unique chance to study microbial life on new land.
- Researchers analyzed the microbial communities in HTHH's sediments and found unexpected diversity, including bacteria that thrive in extreme conditions, rather than the common cyanobacteria expected in early succession stages.
- Despite the island's destruction preventing future studies, the findings highlight the distinct origins and survival strategies of microbial life in newly-formed environments, influenced by nearby geothermal activity.
Flooding affects more people than any other environmental hazard and hinders sustainable development. Investing in flood adaptation strategies may reduce the loss of life and livelihood caused by floods. Where and how floods occur and who is exposed are changing as a result of rapid urbanization, flood mitigation infrastructure and increasing settlements in floodplains.

The most prominent FRP component, commonly referred to as the lambda response, is a large deflection over occipital electrodes (O1, Oz, O2) peaking 80-100 ms post fixation, reflecting afferent input to visual cortex. The lambda response is affected by bottom-up stimulus features and the size of the preceding saccade; however, prior research has not adequately controlled for these influences in free viewing paradigms.
