Abstract
    Human society can be severely impacted by several kinds of natural phenomena such as earthquakes, climate changes, volcanic eruptions, landslides, etc. Therefore, understanding the nature and frequency of such natural processes is fundamental for making correct assessments and mitigations of their associated hazards. Such understanding can be gained by studying lake sedimentary records as these can be generally regarded as high-sensitive archives of natural environmental events. Sublacustrine landslide deposits are important components in these sedimentary records, but their significance has not been studied often.This PhD thesis evaluates the wide range of information that can be extracted from sublacustrine landslide records by analyzing high-resolution reflection seismic profiles and sediment cores. In this way, new insights are gained regarding following topics:i) The processes governing the frontal development and mobility of subaqueous landslides.ii) The hydrological variability over the last 140 000 years in equatorial East Africa.iii) The use of subaqueous sediment volcanoes as an additional paleoseismological proxy.iv) The recurrence pattern and mode of megathrust earthquakes in South-Central Chile.
