Now this is impressive!
The waves from the record-breaking quake lasted about 10 hours — a very long time, considering no previous Marsquakes exceeded an hour.
Wow. I have felt a few earthquakes in Oklahoma but I can't imagine a 10 hour quake at 4.7 magnitude. Not massive, but long lasting. Crazy long lasting.
