What do we have here? Titled "Breathing pavement". Found it described as being over the site of a collapsed volcano. (film poklatkowy)
choć inni obserwatorzy twierdzą:

Several other sites show that it is a dock and claim that it is caused by the waves. not a volcano as was claimed in the comments that this was taken from.
