tivity on the carmel faul

2. Research Objectives
The main objective of this study is to date paleo-earthquakes on the CF during the
Quaternary by means of damaged cave deposits.
Particular aims:
1. Dating collapses of speleothems by radiometric methods.
2. Establishing a viable connection between these collapse events and seismic events
during the Quaternary.
3. Exploring the connection between seismic ac<strong>tivity</strong> on the CF and the above
mentioned events in order to increase the paleoseismic data base for the CF
region.
4. Exploring the connection between the above mentioned events and the DST in
order to test the results of the main research objective.
3. Methodology
3.1 Mapping
Figure 10 is a plan of the chamber and the structural features that could indicate
seismic ac<strong>tivity</strong> within it in Denya Cave. This plan was drawn up in a two dimensional
method using the azimuth and distance of relevant points (samples, structural features and
chosen points along the cave walls) from a central location (sample DN-1). It proved to
be most accurate and useful for the purposes of this study.
Each speleothem sample was mapped and photographed and samples established as
probable seismites were marked (Fig. 10). All samples obtained are from the upper
chamber of Denya Cave. Speleothems in the lower chamber are not abundant and are
very hard to reach. Therefore, for the purpose of this study they were not sampled for
seismites.
3.2 Speleothem sampling
Speleothems assumed to be seismites were mapped, photographed and removed in as
complete a state as possible. Photographs of all Denya Cave samples along with detailed
descriptions and the location of each sample on the plan created of the upper chamber of
