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.

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.

The height of the tsunami caused by the Sulawesi earthquake in 2018 was higher than that estimated from the magnitude of the earthquake, and its cause is not well understood. Although it is conceivable that tsunamis originated from landslides in several cases, it is not known whether landslides were occurring in the coastal area at the time. This report describes the results of a field survey conducted to investigate the traces of subsidence and the characteristics of the tsunami incidents in the bay far from the epicenter. Subsidence was observed at a minimum of seven points along the coast; in accord with the reports of eyewitnesses, this suggests that subsidence might have generated tsunamis.

Healthy housing is one of the needs that must be completed in order to support the householders to obtain an optimal degree of welfare for their living. The aim of this research is to determine how far the housing type 45, Panorama Indah Residence, Pekanbaru, qualified as a healthy house according to the Directorate General of Human Settlements, Department of Public Works of 1986. The criteria of a healthy house are divided into four (4) aspects, namely: amenities, health, building intensity, and affordability. The parameters of a healthy house, particularly health aspects, include adequacy of lighting, ventilation, and the supply of clean and drinking water; the disposal of household waste water, rain drainage, and household waste; also all parts of the house, including floors and walls, must not be humid, and be unaffected by pollution from dirty water and air. This research used synchronising the regulations method with the real condition by conducting a direct field survey and was analysed by design document. The results of this research indicated that the housing type 45 has not met all the demands of a healthy house requirement, particularly the health aspect. This included the lighting, lack of ventilation and unavailable trash cans in the area of the housing.
