You need to remember that seismic activity is measured on a logarithmic scale, not a linear one.
For example, a tremor with a magnitude of 5 is 10 times as strong as one with a magnitude of 4. Then a tremor/quake with a magnitude of 6 is 10 times as strong as one with a magnitude of 5, and so on. (So going from a magnitude of 4 to a magnitude of 6 requires the seismic shock to be 100 times as strong).
Taking the figures of 3.8 (reported off Scarborough, from your link) and Danny's figure of 6.75 (for a Tsunami to occur), shows that this morning's tremor was roughly one thousandth of the strength needed to cause a Tsunami. I reckon the good folk of North Yorkshire should be safe enough!
