A tsunami generated by The Great East Japan Earthquake inundated 3.1 − 5.4 km inland of the lowlying coastal areas of the Tohoku district, Japan, leaving sand and silt deposits over parts of the inundated areas. Applying cluster analysis to the deposits to ascertain their heavy metal compositions, we tried to estimate the tsunami deposit origin and attempted to ascertain their characteristics and distribution based on the shoreline topography and the land use of the backland. Cluster analysis results revealed that most tsunami deposits have similar metal compositions to those of marine sediments. The results suggest dominant marine sediment origin. The tsunami deposits showing soil origin of a unique location were subjected to strong tsunami waves because of the topography of surrounding areas. Moreover, a unique location around a building that disturbed the tsunami wave water currents showed soil origin. The silt contents in tsunami deposits were influenced by differences in tsunami wave water currents attributable to differences in shoreline topography. The metal compositions of tsunami deposits reflected both the mineralogical characteristics of the sediment and pollution profiles of the backland land use.

“…In addition, modifications may be observed in the coastline, dunes and floodplains, altering the original structure and functions of the landscape and human activities as a whole, often with important economic implications. Another of the effects generated by these natural processes is the accumulation of debris, possibly millions of m 3 over the flooded area, causing serious geographical-environmental problems such as soil and groundwater contamination, sanitary emergencies, etc [98].…”

Coastal zones are very dynamic and fragile environments, constituting a landscape ever more heterogeneous, fragmented and with increasing levels of complexity due to the changing relationship between man and nature. Integrated coastal zone management therefore requires detailed knowledge of the system and its components, based-to a large extent-on technical and scientific information. However, the information generated must be in line with the political requirements necessary for decision-making and planning. Thus the use of indicators to give a simplified view of the many components of the territory, and at the same time to provide important information about patterns or trends, becomes a tool of the utmost importance. These indicators can be understood as measurable characteristics of the environment, which facilitate comprehension of the processes occurring at different scales and serve as a reference to inform the population and support decision-making. The aim of the present note is to demonstrate briefly the need to develop geographical-environmental and natural risk indicators to facilitate comprehension of the dynamic of spatial and temporal landscape patterns, particularly in coastal environments. This approach offers an historical summary of the natural, socio-economic and political processes which currently make up the territory, and which without doubt will continue to influence it in the future. At the same time, it is proposed that information should be integrated on the basis of this framework with a view to generating spatial decision support systems in a context of planning and integrated management of the coastal zones of Chile.

“…While the seriousness of the contamination is difficult to assess (Bird and Grossland, 2011), shortly after the disaster the Japan Society of Material Cycles and Waste Management disclosed data including types and locations of carcinogen compound spills (Misuzu Asari, et al, 2013). Furthermore, the Ministry of Environment has conducted monitoring activities for soil and groundwater in the affected area, concluding that high levels of hazardous chemicals were found near the facilities where the particular detected chemicals were stores (Inui et al, 2012).…”
