Earth Shaking Passage - Dominica

We arrived at Dominica on the evening of November 30th. We were surprised to hear the next morning that 3 earthquakes had taken place under us yesterday as we made our passage. We were just 15 miles away from one when it happened.
All 3 quakes were approximately 150 miles below us. They registered in magnitude 7.4,5.1,and 5.0. Fortunately no tsunami was generated and no damage was reported.
When we picked up the weather through Eric on our single-side band radio he reported that they were quite noticeable where he was in Trinidad. He reported that he sat down and counted out the one tremor for 1 minute and 15 seconds.
There were reports as well from as far in the other direction - Puerto Rico.
Thankfully, we noticed nothing unusual.
