Researchers have discovered the remains of a royal wine cellar at the Tel Kabri archaeological site in Northern Israel. They found ~40 crushed jars, which equals about 3,000 bottles, and they were able to analyse the chemistry of the organic traces from the jars. It’s clear that they contained red and white wine, which was spiced with “honey, mint, cinnamon bark, juniper berries and resins” as it was common 1,700 BC. The fact that all jars contained wine with the same chemical fingerprint led the researchers to conclude that the wine had a high quality and was, therefore, likely part of the Canaan palace’ reserve. This is already a pretty good story, but the New York Times also mentiones that “the cellar was destroyed 3,600 years ago in some violent event, perhaps an earthquake“. Yee-haw, archeoseismology! Here we go! But wait – what do we actually know about the earthquake? From the image in the NYT we do not see much, some broken jars only. What would we expect if an earthquake destroyed the cellar? There should be some earthquake archeological effects like these:
An event horizon would be nice, with some damaged structures around. Also, we would expect to see some destruction in nearby archaeological sites of the same age – if there are any. Marco (2008) has a nice overview about EAEs in Israel and describes the features that can be observed. Written reports might not exist since 3,700 years is a pretty long time. If the quake made this cellar collapse, it could have triggered some earthquake environmental effects in the vicinity, like rockfalls, liquefaction, cave collapses etc. If it wasn’t only a local event but a major quake that occurred, let’s say, at the Dead Sea Fault (DSF), then those effects could be preserved even at distant sites.
Unfortunately, I couldn’t find any paper on that story and it seems that the work was only presented at the annual meeting of the American Schools of Oriental Research. The presentation is not online, but it might have been given in the session “A Decade of Investigations at Tel Kabri, Israel: 2003-2013“.So we have to wait for more news and especially for the information that points to earthquake damage. For the moment, we can only check if we have a suitable event from the paleoseismological record. Good thing is that there is a lot of work on the local paleoseismology and archaeoseismology.
The site is only 50 km away from the Sea of Galilea (Lake Kinneret), so the paleoseismological record from this part of the DSF would be a good candidate for an earthquake. (It’s only 40 km away from the Carmel Fault in the south…). Marco et al. (2005) did 3D trenching there. They claim two seismic events after 1000 AD and found that the slip rate of the Jordan Fault strand is ~3 mm for the last 5000 years, based on an 15 m offset channel. Braun et al (2012) describe an event 4800 years ago from speleothems in the Denya Cave near Haifa. Katz et al. (2012) report on five earthquakes exceeding magnitude Mw6.0, dated ca. 45, 40, 35, 10, and 5 ka BP. Plus, they found a younger event, but without a more precise time range. Garfunkel (2012) nicely sums up the data available on the Quaternary slip rate, but there’s no clear hint for an event 3,700 years ago – it’s just that the slip rate of the DSF is pretty high. It’s actually so high that a number of quakes must have occurred in the last 5 kyr.
To sum up: We do not have a good earthquake candidate, although the general tectonic setting is favourable and paleoseismicity is really high. Several strong events must have occurred in the last 5,000 years BP, but for our wine cellar we must wait for more info from the archaeologists. An earthquake would make an even better story and I think we could read it in Nature, but there’s a need to make sure that it’s not only catastrophism. The “Minoan Earthquake” on Crete Island is a good example – recent papers reveal that “The hypothesis of a seismic storm causing the demise of Minoan Crete is not supported by our analysis of archaeological evidence.” …
