This? North of Napa Valley.




That's a damn lot of quakes in one area.

Big picture. These are all small.

All data comes from USGS, but just plotted out, as you noted, on AppleMaps instead of Google.

Apparently 99 cents. It runs on macs with an M-series CPU even if you purchase it for iphone/ipad.

I just take a screensnap, though clicking on any one event (pin) will get you the USGS page.

HTH

I probably got it while living in the bay area.

There may be websites that do similar things, but for obvious reasons, I haven't resorted to any of them.

I clicked on the 4.7 and it took me to that USGS page.

Data provided by US Geological Survey.

Well one was in Michigan and one was in Ontario but not all that far apart.

Imagine if the volcano near Clear Lake came back to life.

Looking around I found this very detailed report from today on youtube .

Here's a map of 2.5 and above:

If these small earthquake swarms meant anything more than the usual grinding of plate tectonics we'd be predicting big earthquakes by now.

Best be safe and assume the big earthquakes might happen at any time and have a few days of drinking water and food that doesn't need refrigeration on hand.

I believe as the Earth overheats Volcanism might be our only safety hatch. The current rate of warming is unprecedented in the entire geologic history. The increase in CO2 concentrations we have accumulated over 200 years took almost a million years. The only other safety mechanism might be if the Atlantic current stalls. I feel that this warming might make earthquakes increase too.
