The frequency of earthquakes in this regions is remarkable. Here is a list of earthquakes of 3.0 magnitude or greater in the last 3 days. MAP 3.7 2019/07/23 16:45:48 35.887N 117.720W 6.9 18 km (11 mi) ESE of Little Lake, CA MAP 4.1 2019/07/23 00:45:02 35.626N 117.428W 5.2 16 km (10 mi) S of Searles Valley, CA MAP 3.9 2019/07/22 18:36:18 35.743N 117.560W 3.0 14 km ( 9 mi) W of Searles Valley, CA MAP 3.0 2019/07/22 13:12:27 35.643N 117.445W 2.9 14 km ( 9 mi) SSW of Searles Valley, CA MAP 3.0 2019/07/22 11:31:20 35.852N 117.666W 3.6 24 km (15 mi) ESE of Little Lake, CA MAP 4.2 2019/07/22 09:26:56 33.996N 116.044W 7.9 16 km (10 mi) S of Twentynine Palms, CA MAP 3.1 2019/07/22 02:45:10 35.957N 117.714W 3.1 18 km (11 mi) E of Little Lake, CA MAP 3.0 2019/07/21 10:09:22 35.699N 117.543W 10.1 15 km ( 9 mi) WSW of Searles Valley, CA MAP 3.1 2019/07/21 04:56:11 35.656N 117.513W 10.0 15 km ( 9 mi) ENE of Ridgecrest, CA MAP 3.1 2019/07/21 03:41:37 35.609N 117.475W 7.2 18 km (11 mi) E of Ridgecrest, CA MAP 3.0 2019/07/21 00:36:57 35.778N 117.618W 7.7 18 km (11 mi) NNE of Ridgecrest, CA

  Paul Nicholls made an excellent visualisation of the sequence after the Christchurch (New Zealand) quakes https://www.christchurchquakemap.co.nz/all https://www.christchurchquakemap.co.nz/all . The https://geonet.org.nz https://geonet.org.nz site also got an update at that time and is fantastic for live data.

What happens if you have a property boundary that gets offset by a fault moving - do you own the moved land or do you own own the land that has moved into your area on a map and lose the land that moved out?

  Same thing that happens when a border defined by a river changes due to the river changing it's flow. There will be a dispute with uncertain outcome.

  Time for some algebra of sets? Do you only own the intersection? Do you own the union?

  Isn't land still mostly defined by physical markers? The distances between the markers would change, and thus the property sizes.

    If my house moved to my neighbor's yard after an earthquake...he could have it. I'm outta there. Just kidding. It is an interesting question though. I suppose the legal answer would vary by locality. It seems that any definitions derived by GPS, which normally would seem to be most accurate, would be too inflexible in this circumstance. It would seem hardly fair to get sued because you left your house in their new front yard.

The visualization is fascinating, but the really interesting thing to me is that Google Earth had what appear to be custom imagery of the affected area within a day or two of the event.

The american obsession with the word "earthquake" ia fascinating to me. I have never understood why, otherwise intelligent and eloquent native english speakers, choose to call small vibrations of tectonic plates as "earthquake" instead of what in theory should really be the more appropriate word: Tremors French, Spanish and German languages do not make this same error. Is english at fault? ? Am i wrong? Or is there more to it?
