Muscoy is located in San Bernardino County, within the Greater Los Angeles Area, and the San Andreas Fault runs through this region. Specifically, the earthquake’s epicenter was approximately 7.4 km (4.6 miles) north of Fontana

The San Andreas Fault’s southern segment, known as the Mojave segment, extends through San Bernardino County, passing along the northern base of the San Bernardino Mountains and through areas like Cajon Pass, which is relatively close to Muscoy.​
 
Another video by Stefan Burns, this time making the point that what just occurred in Kamchatka could be part of a process in the 'ring of fire' that, sooner or later, affects the US West coast - which is now seeing some activity near the San Andreas fault.

Burns, btw, seems like one of the more-well rounded commentators on this subject. In another recent video he brought up the idea, in so many words, of a possible relationship between human consciousness and sun activity, earthquakes, etc. He posed it as a possibility and a question in his mind that was pleasantly surprising to hear.

At least 114 aftershocks have been reported as of July 30, 2025, according to the USGS, which detected at least 35 aftershocks greater than magnitude 5.0 in the first few hours after the main earthquake. The strongest aftershock recorded was magnitude 7.0, occurring 24 minutes after the main earthquake. Other significant magnitudes include M6.9, M6.7, M6.4, and M6.2.

Experts indicate that aftershocks may continue for days, weeks, or even months due to the tectonic readjustment process in the region, which is highly active due to the subduction of the Pacific plate beneath the Okhotsk plate.

The main M8.8 earthquake on July 30, 2025 occurred at a depth of approximately 20.7 km according to the USGS, and aftershocks have occurred at depths ranging from 20 km to 69 km, which are considered shallow. (earthquakes deeper than 70 km are considered intermediate depth earthquakes, and deep earthquakes occur at depths greater than 300 km) Earthquakes in Kamchatka are usually shallow due to the nature of the subduction zone.​

Earthquake shakes New York City

A 3.0 magnitude earthquake struck northern New Jersey late Saturday night, with tremors felt across parts of New York City
www.rt.com www.rt.com

An earthquake with a preliminary magnitude of 3.0 struck northern New Jersey late Saturday night, with tremors felt across parts of New York City, officials have confirmed.

According to the United States Geological Survey (USGS), the quake occurred at 10:18pm local time and was centered in Hasbrouck Heights, New Jersey, roughly six miles beneath the surface. While considered minor, the seismic event was strong enough to cause noticeable shaking in several nearby areas, including parts of Manhattan and the Bronx.

New York City Emergency Management (NYCEM) issued a statement shortly after the incident, noting that it was “monitoring and investigating” the incident.

“Be prepared for possible aftershocks. These may follow minutes, hours, or even days after the initial quake,” NYCEM said in an update on X, adding that no immediate protective action was necessary but advising residents to check for hazards.

It is around 50 miles from me, I haven't felt any shaking.
 
Dutchsinse thinks that the USGS overstated the strength of the Kamchatka earthquake by an order of magnitude, that it was below 8.0. The evidence he cites are the missing larger tsunami waves, lack of destruction in the nearby towns on Kamchatka, other countries (including Russia) reporting that it was 7.5-7.9, that none of the individual stations listed on the USGS website reported an 8.8, etc.

He thinks the deep state wanted to test the emergency procedures across many countries with Pacific coasts, including the US.

Now he points out that what we are seeing near Kamchatka are mostly not aftershocks because these earthquakes occur now up to 500-1000 km further south (an aftershock would be within 50-100 km).

He thinks there is a chance for an actual much bigger earthquake in that area over the next days.

Dutchsinse tends to resort to conspiracy theories and oversimplifying the available information to attract an audience.

Taking into account the reports from the agencies, on average the event had a magnitude of 8.3.

As Dutchsinse mentioned, KB-GS-RAS (Geophysical Survey of the Russian Academy of Sciences) reported that the event had magnitude 7.5

However, everything indicates that the strength of the earthquake must have exceeded M8.5, given the large number of aftershocks ≥M6.0 that have occurred subsequently and in a short period of time.

According to Volcanodiscovery data (Recorded aftershocks: 200 quakes so far)

● Jul 30, 2025 11:25 am (Kamchatka)
M7.2 -90 km (56 mi) SW of main shock

None of the ≥M6.0 aftershocks have exceeded 213 km (Aug 01 M6.2) from epicenter. Neither did the aftershocks with magnitudes less than 6.0

The M8.8 Kamchatka earthquake ruptured a fault plane approximately 600 km long and 200 km wide, according to USGS fault models. Aftershocks are expected to occur within and around this rupture zone, which could extend up to twice the rupture length. Other sources indicate that aftershocks could occur at distances up to 870 km from the epicenter. For comparison, the 2011 M9.1 Tohoku earthquake in Japan had aftershocks spanning over 500 km along the subduction zone.

So Dutchsinse is incorrect to assert that earthquakes 500-1000 km south of the Kamchatka mainshock cannot be aftershocks.

Why did destructive tsunamis not occur in Kamchatka after the M8.8 earthquake, as they did in Japan?

Grok:
​
To understand why the 8.8 magnitude earthquake on the Kamchatka Peninsula on July 30, 2025 did not generate destructive tsunamis like the 2011 Tōhoku earthquake in Japan (Mw 9.1), we must analyze the differences in earthquake characteristics, geological conditions, and factors influencing tsunami generation. The following explanation is based on available information and principles of seismology:

1. Characteristics of the Kamchatka Earthquake (Mw 8.8, 2025)

● Magnitude and rupture: The Kamchatka earthquake was a subduction megafault event with a magnitude of 8.8, occurring 119 km southeast of Petropavlovsk-Kamchatsky at a depth of 20.7 km. The rupture extended approximately 600 km along the Kuril-Kamchatka subduction zone, with a maximum slip displacement of 12-15 meters.

● Tsunami Generated: A tsunami warning was issued following the event, and tsunami waves were observed, but they were not destructive. According to NOAA data, wave heights were small (generally less than 1 meter in most affected areas, with a maximum of 1.2 meters in Petropavlovsk-Kamchatsky). Alerts were quickly lifted, and no significant tsunami damage was reported.

● Location: The epicenter was located off the east coast of Kamchatka, in a remote region with low population density and far from large urban centers.

2. Comparison with the Tōhoku Earthquake (Mw 9.1, 2011)

●Magnitude and rupture: The Tōhoku earthquake was more powerful (Mw 9.1) with a larger rupture area (approximately 500 km long by 200 km wide) and a maximum slip of up to 50 meters in some areas, much greater than in Kamchatka. This greater energy release contributed to a more significant displacement of the seafloor.

● Destructive Tsunami: The Tōhoku tsunami generated waves up to 40.5 meters high in some areas (average of 10-15 meters on the coast), causing devastation on the east coast of Japan, with more than 18,000 victims and extensive damage. The waves traveled across the Pacific, affecting even distant regions such as Hawaii and South America.

● Location: The epicenter was 70 km off the coast of Sendai, near densely populated areas, which amplified the impact of the tsunami.

3. Factors Explaining the Difference in Tsunami Impact

Several factors determine the generation and severity of a tsunami, and these differ between the two events:

a) Magnitude and Seafloor Slip
Kamchatka: Although the Mw 8.8 earthquake was very powerful, its maximum slip (12-15 meters) was less than that of Tōhoku (up to 50 meters). Tsunami generation depends directly on the vertical displacement of the seafloor, which lifts or displaces large volumes of water. A smaller slip in Kamchatka resulted in a less significant displacement of water.
● Tōhoku: The enormous slip in Tōhoku caused a massive displacement of the seafloor, generating much larger tsunami waves.

b) Fault Geometry and Rupture Direction
Kamchatka: The rupture extended mainly along the subduction zone (600 km, northeast to southwest), but the slip was predominantly horizontal (strike-slip in some areas) with a limited vertical component. This reduces the ability to generate large tsunami waves, as tsunamis require a strong vertical uplift or subsidence of the seafloor.

●Tōhoku: The rupture had a more pronounced thrust component, with significant vertical uplift of the seafloor near the Japan Trench. This displaced a massive volume of water, amplifying the tsunami.

c) Depth and Location of the Epicenter
Kamchatka: The epicenter was 20.7 km deep, in a region of the subduction plate with a steeper slope. This may have limited direct vertical displacement on the seafloor surface. In addition, the epicenter was 119 km from the coast, which allowed some dissipation of wave energy before reaching land.

● Tōhoku: The epicenter, at a depth of 30 km, was closer to the coast (70 km), and the rupture occurred in an area where the Pacific plate subducts with a geometry that favored a large uplift of the seafloor, maximizing the impact of the tsunami on the coast.

d) Seafloor Topography
Kamchatka: The Kuril-Kamchatka subduction zone has a deep trench (up to 10 km), but the seafloor topography may not have channeled the tsunami waves as efficiently toward the coast as in Japan. The Kamchatka coast is more rugged and less populated, which also reduces the perceived impact.

● Tōhoku: The Japan Trench and the narrower continental shelf off the east coast of Japan allowed the tsunami waves to amplify as they approached the coast, especially in areas with bays and coastal plains that channeled the waves inland.

e) Population Density and Coastal Vulnerability
Kamchatka: The Kamchatka Peninsula is remote, with a population of approximately 310,000, concentrated mainly in Petropavlovsk-Kamchatsky. The areas near the epicenter are sparsely populated, and the coastline is mostly rugged, limiting potential damage even if the waves had been larger.

● Tōhoku: The east coast of Japan is densely populated, with cities such as Sendai and Fukushima directly exposed. The low-lying coastal plains allowed the tsunami waves to penetrate kilometers inland, causing massive devastation.

f) Warning and Preparedness Systems
Kamchatka: Russia has a tsunami warning system that allowed for rapid warnings to be issued. The population was evacuated from coastal areas, and the warning was lifted when it was confirmed that the waves were small. This minimized any potential impact.

● Tōhoku: Although Japan has one of the most advanced tsunami warning systems in the world, the magnitude of the event exceeded expectations, and the waves reached the coast in less than 30 minutes, leaving little time for complete evacuations in some areas.​

4. Summary

The Kamchatka earthquake did not generate destructive tsunamis due to:

● A smaller vertical displacement of the seafloor (12–15 m vs. 50 m in Tōhoku).
● A fault geometry with less vertical uplift.
● A location further from the coast and a topography that did not amplify the waves.
● A less populated and more rugged coastal region, reducing vulnerability. In contrast, the Tōhoku earthquake had optimal conditions for generating a massive tsunami: greater slip, strong vertical component, proximity to the coast, and coastal topography that amplified the waves in densely populated areas.

End of Grok analysis

IMO this is very important: "a topography that did not amplify the waves," and we have seen this on several occasions; even a 5.0 earthquake can be destructive depending on the type of terrain. For example, Mexico City is located on what was once Lake Texcoco. This geological and topographical environment significantly amplifies seismic waves during earthquakes, making the city particularly vulnerable to seismic damage. Mexico City is located on jelly, so to speak.

The discovery was not made today according to naturalist Rene Villanueva's Tiktok account, the video was posted four days ago and it is mentioned that the discovery was made one day before the Kamchatka earthquake. He states that the oar were attacked by sharks and, due to their injuries, reached the coast to die.
Double extraordinary find: two oarfish were found off the coast of Baja California Sur (Mexico), an extremely rare event since this species lives at depths between 200 and 1,000 meters.
