Approximately five years have elapsed since the Conference on "Tick-borne Diseases and their Vectors" (Wilde, 1978, University of Edinburgh) was held at the Centre for Tropical Veterinary Medicine in Edinburgh. Theileriosis was one of the main topics at that Conference and some 20 scientific presentations were given. Also in the same year a Workshop on "Theileriosis" was held at the Kenyatta Conference Centre in Nairobi (Henson & Campbell, 1977, IDRC, Ottawa). Both of these meetings provided a valuable up dating of theilerial diseases, and the Proceedings have been a constant source of reference for scientists in the ensuing years. The meetings played a significant role in setting the scene for a number of important advances which have been made since then. In February of this year, attention was focused on these advances when nearly 200 scientists from over 30 countries were assembled at the International Laboratory for Research on Animal Diseases in Nairobi for the international conference on "Advances in the Control of Theileriosis". The interest and concern shown in this subject has now grown to the extent that more than 70 scientific presentations were given over the course of a very busy week. An important facet of the Conference was the attention given to the control of Theileriosis, since this must be the ultimate aim of all those involved with the disease. Control will be difficult.

The beginning of the new millennium has been particularly devastating in terms of natural disasters associated with tectonic plate boundaries, such as earthquakes in Sumatra, Chile, Japan, Tahiti, and Nepal; the Indian Ocean and the Pacific Ocean tsunamis; and volcanoes in Indonesia, Chile, Iceland that have produced large quantities of ash causing major disruption to aviation. In total, half a million people were killed by such natural disasters. These recurring events have increased our awareness of the destructive power of natural hazards and the major risks associated with them. While we have come a long way in the search for understanding such natural phenomena, and although our knowledge of Earth dynamics and plate tectonics has improved enormously, there are still fundamental uncertainties in our understanding of natural hazards. Increased understanding is crucial to improve our capacity for hazard prediction and mitigation. Volume highlights include: Main concepts associated with tectonic plate boundaries Novel studies on boundary-related natural hazards Fundamental concepts that improve hazard prediction and mitigation Plate Boundaries and Natural Hazards will be a valuable resource for scientists and students in the fields of geophysics, geochemistry, plate tectonics, natural hazards, and climate science.
