Earth tremour during the night

A change of word maybe is in order? In the last article I wrote the title as “earthquake”  … maybe I should have instead written  the word “earth tremour” as earthquake carries with it a far more dramatic value.   

Last night a  small earth tremour was felt in this area.

The epicentre was further up the valley into Garfagnana, somewhere near Sillano.
