The Great Basin is a rift with blocks being thrust up and down, if you will. Death Valley is a garben or a block being thrust down between blocks that are being thust up. Lots of volcanic activity can be expected as evidenced by hot springs, etc. over time, Death Valley is sure to be active. That’s geologic time so I wouldn’t move just now.
A part of this is the horst possibly behind the Grand Canyon where a block was up thrust gradually all the while the Colorado River was cutting the canyon rapidly (once again, rapidly is a relative term). I recall there was a creationist article posted ridiculing geology for its denial of “the flood”. There have been any number of great (as in big) floods but they were likely of secondary importance in the Grand Canyon or Death Valley.
Wouldn't this effect occur with the Death Valley region as well? IOW, might the next explosive eruption appear farther to the east?
I'm sure you didn't mean 'garden'. So you meant 'graben?'
