Strong earthquake shakes Brittany http://www.online.ie/news/viewer.adp?article=1847951
30 Sep 2002 A strong earthquake shook the Brittany coast in western France today, rattling homes and sending panicked people into the streets. There were no reports of injuries or serious damage. Worried residents deluged police and fire stations with phone calls after the tremor struck at 8:45 am. The magnitude of the quake, centred outside the village of Lorient, had a magnitude of 5.4. France's national earthquake surveillance network, based in Strasbourg, described the quake as "significant" and uncommonly strong for France. The last tremor of equal magnitude occurred in 1980 in the Pyrenees-Atlantique region. Today's tremor, which lasted less than 12 seconds, stretched from towns throughout Brittany to parts of the Loire Valley. "I was in my office with two other people when we heard a loud sound, like a plane had just broken the sound barrier," said Leon Daniel, a town official in Pluvigner, not far from the epicentre.

This quake apparently was accompanied by a sonic boom.I'm not sure I heard of quakes ocurring with a sonic boom phenomena before. I have heard of fireballs causing sonic booms and earth tremors but this was 5.4M earthquake.
Does anyone know if sonic booms accmpany earthquakes often?
