I can't believe I forgot to mention this in my post on Innsbruck!
Our second night there, after hiking, we woke up at around 4a to the glass doors of our bathroom shaking and rattling. Then I realized the bed was moving!
I laid in bed convinced we'd been through an earthquake but given my earlier freak out, tried to stay calm in case I was just still on edge. However when we woke up around 6:30a or so, I hopped on Google and discovered I was right.
A 6.0 earthquake struck northern Italy and tremors were felt all the way up into Austria (duh). So there you have it, our first earthquake experience.
