Are there any amateur or professional seismologists in the house? Take a look at this:
MAG DATE LOCAL-TIME LAT LON DEPTH LOCATION y/m/d h:m:s deg deg km

That's 3 quakes in three days, of almost identical magnitude and also nearly identical coordinates!
Isn't that a bit like lightening striking three times in the same spot? The poor Claremont Hotel is getting the brunt of it since it sits nearly on top of that geo-coordinate.
Meanwhile...I find I'm actually getting annoyed (rather than scared) simply because all 3 have been characterized by a very noisy (almost a loud bang) sounds before a short, sharp thrust upwards and then nothing but car alarms and dogs barking for 10 minutes. I prefer your quieter 'roller' type that just shimmy through quietly with no warning, and leave again.
Bah...it almost spilled my coffee!
