Field survey of environmental estrogen pollution in the coastal area of Tokyo Bay and Nagasaki City using the Japanese common goby Acanthogobius flavimanus

A post-tsunami survey was conducted along the Myanmar coast two months after the 2004 Great Sumatra earthquake ( Mw=9.0) that occurred off the west coast of Sumatra and generated a devastating tsunami around the Indian Ocean. Visual observations, measurements, and a survey of local people's experiences with the tsunami indicated some reasons why less damage and fewer casualties occurred in Myanmar than in other countries around the Indian Ocean. The tide level at the measured sites was calibrated with reference to a real-time tsunami datum, and the tsunami tide level range was 2–3 m for 22 localities in Myanmar. The tsunami arrived three to four hours after the earthquake.

Analysis of land, its carrying capacity and development strategy of seaweed cultivation in Labakkang, Pangkajene Regency. This study attempts to: (1) analyze the suitability of coastal land that appropriate for seaweed cultivation, (2) determine the carrying capacity of the land for seaweed cultivation, (3) formulate strategies and policies that appropriate for seaweed cultivation. This study used biophysical field survey to assess the region, analyze the suitability of the land as well as the carrying capacity of the area by using a geographic information system. Furthermore, the research analyzed the strategy and policy of development of seaweed cultivation with A'WOT analysis approach. The results of the evaluation of the suitability of land for seaweed cultivation in coastal areas showed that Labakkang has potential approximately 1632.876 ha. The area is suitable for seaweed cultivation activities around 1035.54 ha, and unsuitable area around 597.336 ha. For carrying capacity of seaweed cultivation in the coastal area of Labakkang is for 40.55 units. The priority development strategy of seaweed cultivation is strengthening institutions to make a sustainable seaweed cultivation in Labakkang.

On September 28, 2018, Palu Earthquake caused tremendous damage to the coastal area of Palu, Central Sulawesi, Indonesia. The epicenter was located at 27[Formula: see text]km northeast from Donggala Beach with a 10[Formula: see text]km depth. The magnitude of the earthquake was recorded at 7.4. This study assessed the tsunami overland characteristics and its outcome on the coastal area of Palu. The analysis was conducted based on satellite images and video recordings. The satellite images taken prior and post the event, were analyzed to evaluate the morphological change along the coast. The shoreline retreated up to 158[Formula: see text]m in some places. The tsunami damaged infrastructures along the affected coastal area. Video recordings were collected and analyzed to assess the tsunami overland propagation. The data were verified by field survey. The arrival time and celerity of the wave propagation overland on open area and the urban area were studied. It was found that buildings in the urban area have a significant impact on celerity. The wave propagates faster in the open area than inside the building.

Negative Impacts

Demak coastal area is one of vulnerable areas to tidal flood. Tidal flood that occurs continuously has negative impacts on coastal communities. These negative impacts include the effects of physical, social, economic, and environmental. Thus the necessary existence of community adaptation strategies to face the tidal flood. This study aims to assess adaptation strategies of communities in Demak coastal areas. The methods used in this research are the field survey, in-depth interview and Focus Group Discussion (FGD). Field survey was conducted to collect data on the condition of research area. In-depth interview was conducted to obtain information from the relevant authorities, namely Regional Disaster Management Agency and Department of Public Work. Data were analyzed descriptively qualitative. The results showed that people in the Demak coastal area has several strategies to face tidal flood that often occur in the region. Adaptation is performed on residential buildings, roads, and ponds. Adaptations made by raising building houses, making embankment, planting mangroves in the coastal areas, and forming communities caring tidal flood.
