Further Refinement of the Cat Seismometer

[sepdet]

• Long rolling earthquake, cat sleeps through it: M6.5+, but 100 miles away and/or inland so coastal mountains blocking full strength.
• Long rattling or hard shaking, cat wakes up and stays awake but doesn't hide: M6.5+, about 30 miles away.
• Long rolling, shuddering or swaying earthquake, cat bolts for cover: M6.5+, distance > 50 miles with no intervening mountains (meaning San Diego or Los Angeles.) 
• [NEW 10.40PST 4/22/12] Strong shake, rattle and shudder, cat wakes up and then goes back to sleep: about M4, but the epicenter is within 5 miles. 

Continuing to collect data... 

Update: hey, cool, this is what it sounded like (here with a bit more bookshelf rumble):
