Only the most desperately pedantic 
paleoseismologist would mention that April 
      
6 was the 431st anniversary of the 1580 
Dover Straits earthquake. As with the Basel 
event, there's considerable doubt about 
      the 
Richter strength of the event: estimates 
range from 5.3 to 6.0. There is also no 
general agreement on which fault or faults 
      
were involved, or where the epicenter is 
likely to have been. In a daring leap of logic, 
unencumbered by statistics, 
      sampling sizes, 
correlations or other considerations, several 
Puritan theorists of the time asserted the 
quake was caused by 
      London's emphasis on 
theater. We note that English drama has not 
had a Jonson or a Shakespeare in 400 
years. Since England 
      has been largely 
earthquake-free, perhaps the Puritans were 
correct. We are hard at work trying to 
determine what literary 
      effort might have 
triggered the 2007 Kent event. In the 
meantime, we did run some simulations of 
major marine seismic 
      events in both the 
North and Celtic Seas in an effort to 
determine what impact an event in either 
region would have on the 
      Chunnel.
