Over the past 18 hours, the U.S. Geological Survey has reported earthquakes in B.C. and four states along the Pacific Coast of North America.

The first was a 3.5-magnitude shaker at 11:25 p.m. last night not far from Olympia, Washington.

That was followed at 2:34 a.m. and 2:43 a.m. with magnitude 3.2 and 2.5 earthquakes near Lakeview, Oregon.

At 3:09 a.m., there was a magnitude 4.0 earthquake 200 kilometres southwest of Port Hardy.

Then at 11:09 a.m., there was a 3.9 magnitude seismic event 100 kilometres east and southeast of Adak, Alaska.

Just over two hours later, there was a 3.3 magnitude event near Joshua, California.

Then between 5:14 and 5:23 p.m., there were four earthquakes between 2.5 and 4.0 magnitude southeast of Mammoth Lakes, California.

None of these compare to the 6.0-magnitude shaker near Napa, California, on August 24.

However, they still serve as a reminder that we live in one of the most seismically volatile regions in the world.
