Ninety percent of a crisis is always hidden underwater.

means A massive chunk of ice broken off from a glacier or ice sheet, floating in open water with most of its bulk submerged out of sight.

from From German/Dutch 'Berg,' meaning mountain — the same root that gives 'iceberg' its full, chilling shape: literally 'ice mountain.' It traveled into English through sailors and explorers describing the Arctic and Antarctic seas, where these drifting peaks were vast enough to earn a mountain's name even while most of their mass stayed hidden below the waterline — a fact the word itself doesn't tell you, but the sea did, repeatedly and expensively.
