That is pretty cool?
Yeah, it had an impact in a cave 1,500 miles away.
If it were solid earth all the way, I doubt that it would have had such an impact. However, if there are tunnel systems and cavern worlds all the way, then it's a diffferent story; little resistence.
I find this topic especially interesting. Note how this cave / hole has "never" had its bottom explored:
Devils Hole branches into caverns at least 130 m (430 ft) deep, whose bottom has never been mapped.
Very interesting read: Devils Hole - Wikipedia
Here's the location of the two points on the map, note the connective yellow line is roughly 1,394 miles (2,243 km):
Location of Hawthorne, NV in relation to Devil's Hole (190 miles on the yellow line):
I find the topic particularly interesting since it seems extremely likely, that most of California and on into Nevada sits on a SHELF. Recall our previous discussions about the Navy's submarine base under the Nevada desert at Hawthorne, NV. (Search: Search results for 'Hawthorne order:latest' - MindReach)
Devils Hole is a geothermal pool within a limestone cavern in the Amargosa Desert in the Amargosa Valley of Nevada, east over the Amargosa Range and Funeral Mountains from Death Valley. It is at an elevation of 730 m (2,400 ft) above sea level and the water is a constant temperature of 33 °C (91 °F). The surface area of Devils Hole is about 22 m long by 3.5 m wide (72 ft long by 11.5 ft wide). Approximately 0.3 m (0.98 ft) deep on one end of Devils Hole is a small rock shelf of 3.5 by 5 m (11 by 16 ft). The dissolved oxygen of the water is 2.5–3.0 ppm up to around 22 m (72 ft) in depth, though the shallow shelf can have dissolved oxygen levels as high as 6.0–7.0 ppm in June and July.

Devils Hole branches into caverns at least 130 m (430 ft) deep, whose bottom has never been mapped. According to geologists, the caves were formed over 500,000 years ago. The pool has frequently experienced activity due to far away earthquakes in Japan, Indonesia, Mexico, and Chile, which have been likened to extremely small scale tsunamis.
Below the surface pool, Devils Hole descends approximately 160 feet (49 m) through what is termed the "main chamber" before reaching a narrow opening referred to as the 'funnel'. Through this opening lies a much larger chamber of the cavern system known as Acree's Chasm. Acree's Chasm is approximately 300 feet (91 m) in length, 40 feet (12 m) in width, and has a bottom approximately 260 feet (79 m) below the surface.
Immediately after passing the funnel into Acree's Chamber, a narrow side tube can be found to a diver's left. This side tube proceeds approximately 90 feet (27 m) upward to a chamber with an air pocket, named Brown's Room. The tube leading to Brown's Room has at least 2 offshoots, the higher of which leads to a dead-end filled with a small air pocket, and the lower of which confluences with additional tubes descending from Brown's Room. If the diver instead descends through Acree's Chamber, the first notable landmark is a rocky shelf termed the 'lower ledge,' around 100 feet (30 m) below the entrance to the chamber. The bottom of Acree's Chamber lies around 260 feet (79 m) below the surface, but is not flat. Instead, a portion of the chamber floor descends below this lower shelf; a gradual funnel leads to a hole in the bottom of the chamber featuring a strong current. The hole, later termed the ojo de agua, is 315 feet (96 m) below the surface and just large enough for a diver with equipment to fit through.
In 1965, a teenager who jumped the fence with friends to go SCUBA diving the hole did not come back up. Another went down to find him but did not come back up either. Efforts by five divers to later find their bodies were unsuccessful.
On June 20, 1965, during the second dive of a rescue and then body recovery mission, Jim Houtz with his dive partner, dropped a weighted depth line to a depth of 932 feet (284 m) from the start of this opening, without hitting the bottom of the chamber below. Due to the strong current, small size of the entrance, and unknown depth of the below cavern Houtz termed the "Infinity Room," Jim and his partner chose not to explore this Infinity Room. This mission did, however, confirm that the depth of the Infinity Room of Devil's Hole, and the cavern system itself, has a depth of at least 1,247 feet (380 m) from the surface.

A subsequent USGS exploration into Devils Hole in 1991 by Alan Riggs, Paul DeLoach, and Sheck Exley entered what they found out to be a narrow tube rather than an 'Infinity Room' at 315 feet (96 m), descending to a depth of 436 feet (133 m). The team reported being able to see down to a depth of some 500 feet (150 m), without visualizing the bottom of the cavern.
On March 20, 2012, a 7.4-magnitude earthquake in Oaxaca, Mexico, some 2,000 miles (3,200 km) away and centered roughly 12 miles (19 km) below the surface, caused an undulating 4 feet (1.2 m) rise and fall of the cavern waters, as appreciated by researchers working at Devils Hole at the time. This provided further evidence that Devils Hole cave system was connected to not only the Death Valley Regional Groundwater Flow System, but possibly to even further-reaching underground water systems. The 1991 USGS dive team described the Devils Hole as a "skylight" into the water table.
A team of paleoclimatologists from the University of Innsbruck have been collecting and dating calcite mineral deposits here since 2010. In March 2017, underwater cinematographer Jonathan Bird received permission to assist scientists in a four day expedition to take water and calcite core samples. The IMAX footage was included in the 2020 film Ancient Caves and extra footage was used to create the video documentary Exploring Devils Hole on YouTube.
Similar studies had been done in Devils Hole but are no longer allowed permitted due to the endangered status of the Devils Hole pupfish. Cleaning and disinfection of diving equipment, climbing gear, cameras, etc. using hot water and Steramine followed by at least 30 days of air-drying is required by the National Park Service to prevent contamination of the underwater ecosystem.
On September 19, 2022, a seiche reaching 4 feet (1.2 metres) occurred at Devils Hole after a 7.6-magnitude earthquake hit western Mexico, about 1,500 miles (2,400 kilometres) away. Seiches were also observed in the cave after powerful earthquakes in 2012, 2018 and 2019.
Diagram of Devils Hole Cave (1988)
Located 650 feet (200 m) north of Devils Hole is a separate cave system called Devils Hole Cave (#2). It was first explored underwater to a depth of 70 feet (21 m) by divers from the Southwestern Speleological Society in February 1961. It had been described as being shaped like a boot with fallen rock restriction at the 50-foot (15 m) level leading to a narrow pool of 93 °F (34 °C) water. Since no sunlight reaches the water, algae cannot grow and no fish species are found.
On the surface, the cave openings are connected to Devils Hole by an access road and covered with a locked metal grate. Below ground, a passable deepwater connection to Devils Hole has been theorized but remains undiscovered.
Devil's Hole seems to be on the same latitude as Sacramento, California, and laterally is at the mid point in relation to the San Fernando Valley.
Well, that valley must have been an inland Bay prior to 500 years ago. When the Spaniards first entered the San Francisco Bay, it went on and on and, they salied about 15 miles inland. Now the water is below. And the Sahara was an ocean at one time, and then later there were at least large lakes, and then just Lake Chad but it was huge, and now it is almost gone.
I do think that the Earth is growing and rising! Or perhaps the rising is due to temporary volcanic activity, such and pressure from gas.
(It must be better to live in the hollow cavity!)
