What we don't know:

Local perspective:
The last time a 4.0 earthquake shook western Washington was back in 2023 on the Olympic Peninsula. However, three earthquakes with magnitudes near 5.0 recently struck off the coast of Vancouver Island late Sunday and early Monday.
The 2001 Nisqually earthquake remains Washington's most damaging earthquake, which had a magnitude of 6.8 and lasted about 30 to 40 seconds.
