eas<strong>on</strong>able assumpti<strong>on</strong> that whatever <strong>the</strong> cause of seismic event recorded in Denya Cave,<br />

it is most probable that it originated from <strong>the</strong> CF ra<strong>the</strong>r than from <strong>the</strong> DST. Yet it also<br />

signifies that <strong>the</strong> findings from Denya Cave are not necessarily attributed to <strong>the</strong> CF. It is<br />

<strong>the</strong>refore evident that fur<strong>the</strong>r studies are needed to rec<strong>on</strong>cile <strong>the</strong>se problems.<br />

6. C<strong>on</strong>clusi<strong>on</strong>s<br />

This study successfully established that broken and deformed cave deposits in Denya<br />

Cave <strong>on</strong> Mt. Carmel are speleo<strong>the</strong>m seismites. By using U-Th dating methods <strong>the</strong>se<br />

seismites were dated in order to extend <strong>the</strong> paleo-earthquake record for <strong>the</strong> CF.<br />

1. Broken speleo<strong>the</strong>ms, collapsed structures and cracks observed in Denya Cave,<br />

appear to be evidence of seismically induced damage. The exclusi<strong>on</strong> of n<strong>on</strong>seismic<br />

causes for damage in Denya Cave, as well as various assessments as to<br />

seismic ac<str<strong>on</strong>g>tivity</str<strong>on</strong>g> throughout <strong>the</strong> Carmel regi<strong>on</strong>, affirms <strong>the</strong> likelihood of<br />

earthquake damage.<br />

2. Samples of broken or deformed speleo<strong>the</strong>ms from Denya Cave were mapped<br />

and analyzed. Where a break or deformati<strong>on</strong> of speleo<strong>the</strong>ms was detected a<br />

seismic c<strong>on</strong>tact was identified. Material was extracted by means of a hand held<br />

pneumatic drill from laminae located as close as possible to <strong>the</strong> seismic c<strong>on</strong>tact.<br />

The last lamina preceding <strong>the</strong> break event was termed a pre-seismic sample,<br />

while <strong>the</strong> first <strong>on</strong>e to succeed <strong>the</strong> break event was termed a post-seismic sample.<br />

All samples were dated with <strong>the</strong> uranium decay series method. The samples<br />

were extracted from laminae closest to <strong>the</strong> seismic c<strong>on</strong>tacts, allowing for <strong>the</strong><br />

closest age c<strong>on</strong>straints to seismic events.<br />

3. A classificati<strong>on</strong> method for different types of seismites was added to speleoseismite<br />

analysis in order to determine <strong>the</strong> reliability of <strong>the</strong> results.<br />

Classificati<strong>on</strong> was determined according to <strong>the</strong> type of speleo<strong>the</strong>m, <strong>the</strong> clarity of<br />

<strong>the</strong> seismic c<strong>on</strong>tact as a viable indicator for a seismic event, and <strong>the</strong> ability to<br />

adequately sample material. Type A seismites show clear breaks, which indicate<br />

abrupt events. Type B seismites show noticeable changes in sedimentati<strong>on</strong><br />

patterns, which might be related to abrupt events. In both types pre- and post-<br />
