Micro-quake in New Jersey

We were lying on a NJ beach when the ground shook. Earthquake? No we learned later. The Concorde would remain supersonic until 50 miles out. When air and humidity was just right, a sonic boom would still reach shore. It was not an earthquake. As a result, the Concorde had to go subsonic 200 miles out. Felt like the ground was shaking. But sound alone is not sufficient evidence.

Another time, the ground sounded like it was shaking. An earthquake? Some thought so. Later we learned that a barge carrying aviation fuel had exploded some 17 miles out to sea. The rumbling continued for a few seconds. In hindsight, we thought that light flash a minute earlier was lightning. Amazing that the Inky had the complete story inside that little white box outside our house only 10 hours later.
