I live in LOs Angeles and of course we are earthquake country.
I watch the USGS website throughout the day.
You can go there to gain a lot of info.
Here is where it was felt.
If you click on the Resp you can see where it was intensely felt.

Thank you! I see the 4.5 in Maine...but it got my attention here too!
