Transportation Research Board reports that synthesize information related to landslides and rock fall span more than four decades. Previous reports have been widely used in the geotechnical engineering community as comprehensive, practical sources of information on landslides and their control. Among the most widely distributed of TRB publications, these reports have enjoyed wide international appeal and have been translated into several languages.

The Ninth International Symposium on Landslides (ISL’2004) was sponsored by the JTC-1, the Technical Committee on Landslides of the three sister societies ISSMGE, IAEG, ISRM, the Brazilian Society of Soil Mechanics and Geotechnical Engineering (ABMS) and the Brazilian Association for Engineering Geology and the Environment (ABGE). Significant financial support was received from PETROBRAS Transporte S/A, Furnas Centrais Elétricas S/A, from the Brazilian Ministry of Science and Technology (through CNPq, FINEP) and from the Government of the State of Rio de Janeiro (through FAPERJ). <...>

Lasi II was the second in a series on international meetings dealing with the physical geology of subvolcanic systems and demonstrated the diversity of techniques utilised in the analysis of shallow intrusions. These included both numerical and analogue modelling of magmatic processes, the analysis of magnetic fabrics to understand magma flow, the interpretation of seismic reflection data as well as outcrop-based studies. This diversity of research methodologies was applied to a range of shallow intrusions including sills, dykes and laccoliths as well as the interaction of magma with sediments. The presentations provided new insights into the morphological development of igneous intrusions, in particular re-assessments of the controls on their emplacement; the interactions between propagating magma bodies, between intrusions and overlying volcanic centres as well as magma-sediments interactions and their potential climatic effects. <...>

A comparative analysis of the Late Cretaceous–Paleocene volcanism was conducted for four areas of Kamchatka: the Pravyi Tolbachik–Levaya Shchapina–Adrianovka interlfuve (the northern part of the Tum-rok Range), the area south of the Ipuin River and Mt. Khrebtovaya (the northern Valaginsky Range), the area of Mt. Savul’ch (the upper reaches of the Kitil’gina River, northern Valaginsky Range), and the Kirganik– Levaya Kolpakova interfluve (the Sredinny Range). New petrochemical, geochemical, and isotopic data on the volcanic rocks from these areas are reported. The examination of this material, together with already published data on volcanic and plutonic rocks of similar composition and age, made it possible to establish the following: (1) the considered basaltoids are ascribed to the subalkali basalt–trachyandesite series with transition toward a meymechite–picrite rock association; (2) the alkali content in the rocks of the Valaginsky–Tumrok–Sredinny ranges increases simultaneously with the increase of the Rb content, while the contents of HFSE and radioactive elements decrease and then again increase. Two trends are identified in the Ybn–Cen diagram: a positive trend spanning most of the volcanic and plutonic rocks and a negative trend defined by the data points of the meyme-chite–picrite association. The first trend reflects the rock evolution during crystallization differentiation, while the second trend was produced by different degrees of melting of initial protolith. The possible geodynamic reconstructions of this volcanism are discussed as well
