Wendy, the earthquake was very scary I agree, but by the laws of average and statistics a big one is likely to happen once every 50 years and experts believe that was our big one....
The burglaries are happening on average every night, some nights 3 or 4 being done.
Get the alarm, and like was said already the earthquake advice is to stay indoors and crouch down under a table, or by something solid, like a washing machine, end of your bed etc.
