“…The island's proximity to the Pacific Ocean also contributes to the incidence of hydrometeorological hazards. [42] noted that climate change affects rainfall distribution on Ternate Island. The warming sea surface temperatures and the reccurent El Nino-Southern Oscillation (ENSO) phenomenon in the Pacific Ocean can lead to more rainfall in the Maluku region [72,73].…”

“…The island's geological materials are primarily volcanic in origin, formed through recurrent eruptions that deposited pyroclastic flows, lava flows, lahars, and tephra over millennia [39,40]. The island's steep terrain includes slopes exceeding 25%, with inclines over 40% leading to Mount Gamalama's summit, while coastal slopes range from 2% to 8% [40][41][42]. Ternate also has three lakes-Laguna, Tolire Besar, and Tolire Kecil-formed by the remain active Gamalama volcanic activity located in the eastern and southwestern regions of the island [44].…”

“…The National Disaster Management Agency (BNPB) has identified nine potential hazards on Ternate Island, including floods, flash floods, landslides, extreme weather, extreme waves, abrasion, earthquakes, tsunamis, volcanic eruptions, forest fires, and social conflicts [45]. Recent studies have focused on the impacts of specific (single) hazards, including tsunamis [45,46], coastal abrasion [47][48][49], volcanic eruptions [51], landslides [42,51], earthquakes [53], floods [53][54][55][56], and extreme weather [58].…”

Current trends in systemic risk literature provide new insights into multi-hazard risks that interact and compound with built environments, creating more significant impacts on socio-economic and human systems. Recurrent natural hazards and extreme weather events are more likely to compound and cascade into more impactful events, especially in vulnerable societies. In small-island communities (SICS), including large archipelagos and Small Island Developing States (SIDS), the long-term impact of multi-, compounding-, and cascading-hazards (MCC hazards) can result in persistent vulnerability and residual risks. This is due to delayed responses, limited resources, poverty, fewer evacuation options, and inadequate markets and infrastructure. Using Ternate, a densely populated small volcanic island in North Maluku, Indonesia, as a case study, this paper assesses the impacts of seven types of natural hazards: flash floods, landslides, extreme weather, extreme waves and abrasion, earthquakes, tsunamis, and volcanic eruptions. The research focuses on the multi-hazard impact on population, land use, and infrastructure exposures in 60 villages in Ternate. The findings highlight population density, land use, and infrastructure exposure to multi-hazard risks, providing valuable information on potential losses in future hazard events.

“…Despite the good water condition in most parts of Tunda Island, there is a need to be aware of seawater intrusion, especially in dug-wells near the coast. The condition does not only happen in Panjang Island as explained earlier but also in several small islands in Indonesia such as Karimunjawa -Central Java (Prihantono et al, 2021), Panggang Cay -Seribu Islands Jakarta (Cahyadi et al 2018) and Ternate Island -North Maluku (Nagu et al 2018). Seawater intrusion is the process by which saltwater gets into freshwater aquifers, contaminating the groundwater supply (Kayode et al 2017).…”

Water availability and management for water security on small islands are critical. The purpose of this research is to uncover the water resources issue at a small island community level as well as discourse on the potential threats and sustainable management for water security. Tunda Island, located in the Java Sea, is one of 81 small islands in Banten Province, Indonesia. Data were collected through focus group discussions, open interviews with key persons, direct eld observations, and secondary data gathering. Moreover, we analyzed time series climate data, particularly rainfall and population growth projections, based on data from o cial Indonesian government sites. The monthly mean precipitation is ranging from a low of 48 mm/month in August to a high of 292 mm/month in January. A "surplus of water" occurs from November to May, while months with a "de cit of water" occur from June to October. The majority of

Groundwater resilience on small islands, especially low-lying carbonate islands like Tunda, is vulnerable to an expanding population, demand exceeding supply, contamination from human and animal waste, and climate change-related impacts. This study aims to evaluate the resilience of groundwater resources on Tunda Island, Banten, Indonesia, in response to anthropogenic activities and climate change-induced consequences. The data were compiled and collected from the o cial Indonesian government websites and direct eld observations. Analysis of climate data reveals that January has the highest average monthly precipitation, with 292.32 mm, while August has the lowest, with 48.26 mm. This is proportional to monthly meteorological water storage, with amounts of 299,547 m 3 in January and only 50,001 m 3 in August. Typically, the groundwater levels on Tunda Island are higher than the mean sea level, ranging from 1.07 to 8.71 meters with ow direction from the inland (recharge) to the coast (discharge). Population growth from the last decade (2012-2022) and ten drought events caused by El Nino and positive IOD from 1979 to 2022 have not yet had a signi cant impact on Tunda Island's groundwater resilience. Similarly, the increase in the number of visitors between 2019 and 2021 has had no effect on the island's water security. However, these anthropogenic and natural stresses will inevitably deplete the island's water supply in the future. Hence, water management and planning, including the determination of regional water balances, were required to maintain the water supply and its sustainability.closest to Tunda Island in Banten Province, is also currently experiencing a freshwater crisis (Kepel et al. 2023).The inhabitants of Tunda Island, which has approximately 276 hectares of land, are divided into two administrative regions: Timur Village (TV) and Barat Village (BV). The population density is 543.5 per square kilometer. Aquaculture and shing are the primary sources of income for the island community. Tunda Island is morphologically classi ed as a reef island with an elevation between 0 and 12 meters, according to the digital elevation model (DEM) data. Geologically, Tunda Island consists of Quaternary reef limestone (Rusmana et al. 1991). Nevertheless, Tunda Island has an aquifer system with low productivity, low-to-high transmissivity, and a discharge greater than 10 L/s (Soetrisno 1986). Material and methods Meteorological dataThe meteorological data for Serang, Banten was downloaded from the Agency of Meteorology, Climatology, and Geophysics of the Republic of Indonesia (BMKG) (http://dataonline.bmkg.go.id/home; accessed in 2015) and the European Center for Medium-Range Weather Forecast (ECMWF) (https://www.ecmwf.int/; accessed in 2023). The climate data combination is composed of total daily rainfall from 1979 to 2022. The data was then further processed to obtain the average monthly precipitation (Fig. 1).Composite analysis (e.g., Yin et al. 2022) was used to determine the effect of El Niño-Southern Oscillation ...
