As an addition to Rapaire's title about Bermuda: The author is Larry Kusche.

The original article has stated that it could happen (ship sinking by methane bubble) but that there still was 'no tangible evidence'. A real hazard it is, however, for oil/gas drilling.

With so many ships sailing the ocean since very long times such a sinking may have happened, but only as an extremely rare event. If these events were so frequent that they could explain the large number of supposedly mysteriously sunk ships in in Berlitz' fiction book we would have many reports of near misses or reports from ships close by.
