Theme: Prevention and mitigation of natural and anthropogenic hazards due to land subsidence.
An awareness of problems related to land subsidence and its anthropogenic causes has been growing worldwide since the second half of the Twentieth century. The problem of land subsidence was first included by the UNESCO program of the International Hydrological Decade (IHD), 1965–74. In 1969 UNESCO convened the 1st International Symposium on Land Subsidence in Tokyo. In 1975 land subsidence was retained under the framework of the International Hydrological Program (IHP) as subproject 8.4 “Investigation of Land Subsidence due to Groundwater Exploitation”, and UNESCO IHP formally codified the Working Group on Land Subsidence. In collaboration with UNESCO IHP, IAHS, and other scientific organizations, the UNESCEO–IHP Working Group on Land Subsidence convened eight more International Symposia on Land Subsidence in different countries in Asia, Europe and North America: Anaheim, USA (1976); Venice, Italy (1984); Houston, USA (1991); The Hague, Netherlands (1995); Ravenna, Italy (2000); Shanghai, China (2005); Queretaro, Mexico (2010)．Land subsidence has become an important area of research in Japan, other countries of South East Asia and globally. UNESCO and the Tokai Three Prefecture Investigation Committee on Land Subsidence of Japan invite you to attend the Ninth International Symposium on Land Subsidence (NISOLS) planned for 15–19 November 2015 in Nagoya, Japan. The NISOLS conference will present a high standard of scientific and technical information to scientists, engineers, and end users of the studies on land subsidence and associate hazards.
The amount of the groundwater extraction increased rapidly during a period of high economic growth leading up to the mid-1960s, and land subsidence was generated on a nationwide scale in Japan. The Nobi Plain west of Nagoya is one–subsidence damage was large. Land subsidence in Japan has been largely arrested owing in large part to laws and ordinances that restrict groundwater pumping. However, the accumulated historical subsidence exposes the coastal areas to flooding related to high tides and the tsunamis. Recently, the groundwater control without generating land subsidence is requested from the viewpoint of the hydrological cycle. Moreover, the collapse of underground voids created during mining of lignite causes damages to buildings in the northern part of the Nagoya area. Research on mitigating the collapse of these underground voids is vitally needed. Additionally, the shoreline has subsided as a result of the massive earthquake that overcame the Tohoku region in Japan on March 11, 2011 exacerbating damage from flooding. Research on land subsidence attributed to liquefaction and diastrophism that the massive earthquake caused is needed. Geologists, geophysicist, hydrologists, geotechnical engineers, other scientists, resource managers and stakeholders are encouraged to participate in this symposium and contribute papers describing the development of new techniques for monitoring, analysis, interpretation and prediction of subsidence and (or) related ground-failure/fracturing processes. Case studies of applied science and engineering and social/cultural investigations of these processes are welcome.

2) Risk management of subsidence related hazards
3) Anthropogenic land subsidence in coastal regions
4) Land subsidence related to soil oxidation
5) Anthropogenic uplift (CO2- sequestration included)
6) Land subsidence and liquefaction, due to East Japan Great Earthquake of
March 11, 2011
7) Ground failure (fracturing, fault activation, fissuring)
8) Land surface displacement, measuring and monitoring
9) Numerical Modelling
10) Social, cultural and economic influence of land subsidence
11) Water management strategies
12) Subsurface deformation due to shale gas production
13) Settlements and geotechnical construction activities
14) Seismic activity, triggered by fluid extraction and injections
Call for Papers
Papers/posters are invited on the principal topics outlined above and other topics which fall within the general objectives of the symposium. Abstracts (200-400 words) in English should be submitted on-line in the NISOLS’s Website not later than January 15, 2015. The abstract should contain author’s name, affiliation, address, and key words. It should clearly state the purpose, methodology, results and conclusion of the final paper. Metric units should be used. Please specify whether an oral or poster presentation is preferred (for Japanese speaker’s simultaneous translation will be available). Authors of accepted contributions will be notified by February 6, 2015. A paper is required for all accepted abstracts. There is a limit of 6 pages for each paper, including figures, tables, and references. The text must be in English. More detailed information will be found in the "Author's template for proceeding’s paper for NISOLS 2015" in the second circular. The proceedings will include keynote lectures and only those accepted papers that are presented by the authors of the paper at the symposium and will be published by Copernicus Publishers in association with UNESCO and the International Association of Hydrological Sciences (IAHS).
