What is a "tar shower?" I'm reading about Sodom and Gomorrah on Wikipedia when I come across this:
"One such idea is that the Dead Sea was devastated by an earthquake between 2100 and 1900 BCE. This might have unleashed showers of steaming tar."

What is a "tar shower?"  Are there any documented cases of this?  When I googled this, it went to the visual dictionary referenced in the Wikipedia article, which didn't explain the concept either.
Natural oil seeps are not unusual, the light components evaporate leaving "tar". Then an earthquake could cause a release of gas which if in just the right location could blow the tar into the air.  Normally the gas escapes through the tar and throws it only a very shot distance, like an inch.
