So far planetary alignments Sun-Venus-Uranus; Sun-Venus-Earth and Sun- Venus- Mercury have not coincided with a strong earthquake greater than M6+ and in the worst case M8+ However, there was an increase in the number of earthquakes that occurred in the last 24 hours, which went from 878 to 1136 earthquakes.

Possibly the missing component is the low solar activity over the last four days. The Interplanetary Magnetic Field has not impacted the Earth's field significantly (IMF > 10nT). In the last 24 hours the IMF value has peaked at 5 nT.

WORLDWIDE EARTHQUAKE REPORT AUGUST 15_2023

Moderate seismic activity was recorded in the last 24 hours. A magnitude 5.5 earthquake in Indonesia was the strongest event of the period. Some light earthquakes were recorded in San Antonio de los Cobres Argentina (M4.4) Nabire Indonesia (M4.5) Haida Gwaii, Canada (M4.4) Kuril Islands (M4.6) Severo-Kuril’sk, Russia (M4.7) Adak, Alaska (M4.7) Sand Point, Alaska (M4.0)

Two lunar geometries (Earth-Moon-Mars and Earth-Moon-Neptune) were active in the early hours of August 15. So we will have to wait and see if they influenced the seismic activity of the next hours. So far the number of earthquakes went from 1056 events to 996. The Mars-Venus-Neptune alignment will start at 00:09 UTC on August 16. Significant earthquakes occurred when Neptune participates in a conjunction.
​

The last time a M 8.3 or larger #earthquake occurred was on 16 September 2015 (Coquimbo, #Chile). It happened when #Earth was aligned between #Jupiter and #Neptune. Next time comparable planetary geometry occurs is from approximately August to November 2023.​

No big quakes yet, but obvious clustering of stronger tremors following the planetary conjunctions.​

​

Next up: Mars-Venus-Neptune. My prognosis was that the largest activity will likely occur in the 2nd half of August after much accumulation of energy and stress.​

Mars-Venus-Neptune conjunction coincided with a M6.5 earthquake in Vanuatu

M 6.5 - 42 km W of Sola, Vanuatu
2023-08-16 12:47:40 (UTC)

A high level of seismic activity was recorded for this event. By itself the M6.5 earthquake had a released energy equivalent to 84802 tons of TNT or 5.3 atomic bombs, however, the earthquake was considered by the seismological agencies as light because it occurred at an intermediate depth, that is 193 km (so our underground neighbors did not feel it ) M5.2 earthquake was the precursor to M6.5 earthquake in Vanuatu. The seismic energy subsequently moved to Tonga which recorded an M5.4 earthquake

WORLDWIDE EARTHQUAKE REPORT AUGUST 17_2023

Two powerful M6+ earthquakes followed the Mars-Venus-Neptune conjunction. An M6.0 earthquake on the mid-Atlantic ridge occurred about twenty-three minutes before the M6.3 earthquake in Colombia. So far the strongest aftershock in Colombia has been of magnitude 5.7 and occurred about thirteen minutes after the main event. These events also coincided with the critical Lunar geometry: moon, Earth, Saturn on August 17 (see below for the forecast for the next week).

The 6.3 magnitude earthquake in Colombia had a release of energy equivalent to 42502 tons of TNT or 2.7 atomic bombs. It is possible that this energy will move towards Central America and the Caribbean but also towards Peru and Chile.​

● Earthquake Forecast

Major to great seismic activity is likely to occur in the second half of August.

No major earthquake has occurred so far which means that the greatest seismic activity will probably occur in the second half of August.


Lunar geometry with Neptune is critical in August, raising the potential of an earthquake around 8.5 magnitude, most likely in the second half of the month.​

○ Critical Planetary conjunctions

▪︎ Mars, Venus, Neptune on August 16
▪︎ Mercury, Venus, Uranus on August 17
▪︎ Venus, Mercury, Uranus on August 18
▪︎ Mars, Mercury, Neptune on August 19
▪︎ Venus, Earth, Mars on August 21
▪︎ Sun, Venus, Saturn on August 21
▪︎ Venus, Jupiter, Neptune on August 22
▪︎ Mars, Earth, Neptune on August 22

○ Critical Lunar geometries
▪︎ Moon, Earth, Saturn on August 17
▪︎ Earth, Moon, Mars on August 19
▪︎ Moon, Earth, Neptune on August 19
▪︎ Earth, Moon, Neptune on August 22
▪︎ Earth, Moon, Mars on August 22
▪︎ Moon, Earth, Jupiter on August 23
▪︎ Moon, Earth, Uranus on August 23

Earth is slowly moving between Mars and Neptune. I have been referring to this geometry in August since November. I expect an obvious seismic increase and there is a chance of M8+. The actual seismic response will depend on the tectonic stress levels.​

Seismic laws and fractal surfaces​

In a recent work, scientists relate the statistical properties of earthquakes (magnitude, frequency, etc.) to those of correlated long-range fractal random surfaces. This relationship makes it possible to understand why and how the different characteristics of earthquakes are statistically related.

The Earth does not shake at random. By analysing the vast amount of data in seismicity catalogues, it has been possible to empirically determine two key statistical laws describing their characteristics. The Omori law defines the decrease in the number of aftershocks that occur after a major earthquake, while the Gutenberg-Richter law states that the frequency of earthquakes depends on their magnitude. However, the physical processes governing these empirical laws are poorly understood.

In a recent study, a Franco-Japanese collaboration between the Laboratoire de Physique de l’Ecole Normale Supérieure (LPENS), the Institut de Physique du Globe de Paris (IPGP), Osaka University and the Laboratoire de Géologie de l’Ecole Normale Supérieure (LGENS), revealed a physical mechanism that could explain the origin of these empirical laws. The scientists used several simplified fault models to reproduce the statistical laws governing earthquakes. They then discovered a fundamental link between these laws and the mathematical properties of the random surfaces representing the fault planes.

The study reveals that the stress field accumulated on fault planes prior to seismic rupture has a random, self-similar or fractal structure. This stress field retains its characteristics whatever the scale and thus determines the characteristics of large-scale earthquakes. The Gutenberg-Richter and Omori laws can then be explained by the mathematical properties of random surfaces.

These results, published in the journal Physical Review E., open up interesting prospects: an in-depth characterisation of the random surfaces of fault planes could provide a better understanding of the physical processes associated with earthquakes.

Earthquake magnitude distribution and aftershocks: a statistical geometry explanation​

François Pétrélis, Kristel Chanard, Alexandre Schubnel, Takahiro Hatano

The emergence of a power-law distribution for the energy released during anearthquake is investigated in several models. Generic features are identifiedwhich are based on the self-affine behavior of the stress field prior to anevent. This field behaves at large scale as a random trajectory in 1 dimensionof space and a random surface in 2 dimensions. Using concepts of statisticalmechanics and results on the properties of these random objects, severalpredictions are obtained and verified, in particular the value of the power-lawexponent of the earthquake energy distribution (the Gutenberg-Richter law) aswell as a mechanism for the existence of aftershocks after a large earthquake(the Omori law).

Moderate levels of seismic activity were recorded in the past 24 hours. The highest magnitude event occurred in the Sandwich Islands with a 5.7 earthquake, however, the one that has attracted the most attention is the California earthquake with a magnitude 5.1 which had an estimated energy release of 674 tons of TNT Multiple aftershocks have been recorded, with an M3.5 quake being the highest magnitude so far.

These earthquakes were preceded by the Mars, Mercury, Neptune planetary alignment and the next critical alignment will occur on August 21 when Sun, Venus and Saturn align.

Can hurricanes cause earthquakes? FSU study says absolutely​

In areas offshore of Florida and in the Gulf of Mexico, deep shudders equivalent to a 3.5 magnitude earthquake were found to coincide with the ultimate in low pressure systems — hurricanes.

The pummeling of the sea floor repeatedly by tropical cyclone-forced waves produces an intense seismic source activity that scientists are calling “stormquakes.”

Wenyan Fan, an FSU assistant professor of Earth, Ocean and Atmospheric Science, said

“There was a very strong correlation that whenever extreme storms are present and they are traveling through certain regions, the stormquakes would light up.”

Can hurricanes cause earthquakes? FSU study says absolutely

The topography of the sea floor around Florida takes a pounding during a hurricane, and the Earth feels the jolt.
