WORLDWIDE EARTHQUAKE REPORT OCTOBER 25
Possibly the increase in seismic activity in the past 24 hours is due to "multiple lunar peaks converging with critical planetary geometry" as predicted by SSGEOS.
According to SSGEOS: "The planetary geometry that triggered the seismic increase that we saw today at South Sandwich Islands (Mw 6.3) and Luzon, Philippines (Mw 6.6). There's likely more to come in the coming days.
The earthquake in the Philippines had a preliminary magnitude of 6.6 and as more results came in from the agencies it was adjusted to magnitude 6.4.

Today's #earthquake in #SanJose #California M5.1 was on the Calaveras Fault and is the strongest earthquake recorded in the San Francisco Bay Area since the 2014 M6.0 Napa earthquake.
An omen (Calaveras = skulls) or Mother Earth wishes happy Halloween to the U.S.
An earthquake just shook the Bay Area. Here's what to know about the obscure Calaveras Fault.
The San Andreas and Hayward faults get all the attention in the San Francisco Bay Area, but on Tuesday, the obscure Calaveras Fault made itself known.
A magnitude 5.1 earthquake struck on the fault that runs through the hills east of San Jose, rocking the region and reminding everyone that we live in earthquake country. “The location of the epicenter suggests that this earthquake occurred within the Calaveras Fault zone,” U.S. Geological Survey research geophysicist Annemarie Baltay said in a video posted on Twitter.
Turns out, the Calaveras Fault has the same capability to cause a ruckus as the two big-name faults.
“When we think about hazardous faults in the Bay Area, there are three primary faults, San Andreas, Hayward-Rodgers Creek and Calaveras,” said Richard Allen, director of UC Berkeley’s Seismology Lab. “Calaveras is one of the big three.”
A 2014 report from the USGS found those three faults are the most likely in the Bay Area to see a major earthquake in the future similar to the 1989 Loma Prieta tremor, which killed 63 people. Seismologists discovered that within a 30-year period, from 2014 to 2043, the odds of a magnitude 6.7 or larger earthquake occurring on the San Andreas Fault was 22%, on the Calaveras was 26% and on the Hayward-Rodgers Creek 33%.
The last major quake on the Calaveras Fault was in 2007 when a magnitude 5.5 hit near Alum Rock on Halloween. Before that, in 1984, the fault produced a magnitude 6.2 shaker near Halls Valley southwest of Mount Hamilton.
“It’s an area of seismicity, and these moderate earthquakes are what we’ve seen along this part of the fault in recent decades that cause light shaking and not a lot of damage,” said Stephen DeLong, a research geologist at the USGS Earthquake Science Center at Moffett Field. “It may be that we continue to see these moderate earthquakes, or it may be that this fault may participate in a larger earthquake in the future.”
The Calaveras and Hayward-Rodgers Creek faults are actually strands of the San Andreas Fault system, branching off from California’s intricate San Andreas network of faults. The Calaveras branches out from the San Andreas south of the Bay Area near Pinnacles National Park. It heads north, cutting through the town of Hollister, cutting into the hills east of San Jose, running right under Mount Hamilton and then through Pleasanton, San Ramon and the Walnut Creek area, DeLong said.
Tuesday’s quake struck just south of Mount Hamilton at 11:42 a.m. There were no reports of damage, but more than 21,000 people, from Central California to the North Bay, reported on the USGS website that they felt shaking.

WORLDWIDE EARTHQUAKE REPORT OCTOBER 27
A magnitude 5.0 earthquake near Ometepec, Guerrero, Mexico, was reported by USGS but according to the SNN (Servicio Sismológico Nacional), the earthquake had a magnitude 4.9 and it occurred at 97 kilometers south of San Marcos (pop. 6,600) , with Latitude 15.93 and Longitude -99.22. The earthquake occurred at a shallow depth of 21.8 km beneath the epicenter early morning on Thursday, October 27th, 2022, at 3:45 am local time.
So far no damage or further comments have been reported regarding the earthquake that shook San Marcos early this morning, although mexicans reported that they felt it in Zihuatanejo and some in Mexico City.
After the first earthquake, at 3:45 am, there was an aftershock, this time with a magnitude of 4.3 and an epicenter 88 km south of San Marcos. (USGS recorded it as M4.9) According to the data of both earthquakes, they occurred near the Guerrero Gap. Guerrero's seismic gap runs from Acapulco to Zihuatanejo, an area where, according to specialists from the National Autonomous University of Mexico (UNAM), no earthquakes greater than M7+ have occurred in decades. The fact that the Guerrero gap has not reported an earthquake of more than 7 degrees since the beginning of the last century worries Mexican seismologists.
The seismic gap is located 150 kilometers from Mexico City. If an earthquake of 8 degrees or more occurs, the consequences could be devastating since the proximity of the capital of the country and other entities of the center with the gap would result in damages two or three times greater than those registered in the 1985 earthquake, specialists say
According to Dr. Victor Manuel Cruz Atienza of UNAM, seismic activity in the Costa Chica of Guerrero is currently "abnormally high" and this seismic scenario has similarities with the events prior to the magnitude 9 earthquake in Japan in 2011.

Ica in alarm due to chain of earthquakes with magnitudes of up to 5.9: 11 so far today
Ica has not stopped shaking. At 5:52 p.m. and 6:19 p.m. this Friday, two new earthquakes -of magnitude 5.6 and 4.8, respectively- shook the southern Peruvian region and generated alarm among the population, since there have been eleven earthquakes so far this day.
At 3:22 p.m. the strongest quake of the day occurred, with an epicenter located 111 kilometers southwest of Ica. It had a depth of 26 kilometers and intensity V, according to the National Seismological Center of the Geophysical Institute of Peru (IGP).
The Directorate of Hydrography and Navigation of the Peruvian Navy has specified that the most recent earthquake, of magnitude 5.9, "does not generate a tsunami". The mayoress of the province of Ica, Emma Mejía, indicated to RPP that so far no aftermath has been registered.
Peru is located in the area known as the Pacific Ring of Fire, where 85% of the world's seismic activity is registered. In 2007, Pisco (Ica) was the scene of one of the most violent earthquakes in recent years, second only to the Arequipa earthquake of 2001.
The earthquake had a magnitude of 8.0 on the moment magnitude scale, a maximum intensity of IX on the Mercalli scale and a duration of 3 min 30 sec. It left 600 people dead, 1,300 injured, 48,000 houses completely destroyed and uninhabitable, and 450,000 people were affected. The most affected areas were the provinces of Pisco, Ica, Chincha, Cañete, Yauyos, Huaytará and Castrovirreyna, as well as Lima.

According to SSGEOS the planetary geometry is similar to may 1960 and march 1964
On May 22, 1960, the most powerful earthquake in recorded history—magnitude 9.5—struck southern Chile. The rupture zone stretched from estimates ranging from 500 kilometers (311 miles) to almost 1,000 kilometers (621 miles) along the country’s coast. The event was named after the city most affected by the quake, Valdivia. The Valdivia earthquake left two million people homeless, injured at least 3,000, and killed approximately 1,655. The economic damage totaled $550 million (more than $4.8 billion, adjusted for 2020 inflation). The Valdivia earthquake triggered a massive tsunami that raced across the Pacific. Waves wracked coastal communities as far away as New Zealand, Japan, and the Philippines. In Hawai'i, the tsunami devastated the coastal town of Hilo, killing 61 people.

On March 27, 1964 at 5:36pm local time (March 28 at 3:36 UTC) an earthquake of magnitude 9.2 occurred in the Prince William Sound region of Alaska. The earthquake rupture started approximately 25 km beneath the surface, with its epicenter about 6 miles (10 km) east of the mouth of College Fiord, 56 miles (90 km) west of Valdez and 75 miles (120 km) east of Anchorage. The earthquake lasted approximately 4.5 minutes and is the most powerful recorded earthquake in U.S. history. It is also the second largest earthquake ever recorded, next to the M9.5 earthquake in Chile in 1960.

The map shows the epicenter of the 1964 Alaska Earthquake (red star), caused when the Pacific Plate lurched northward underneath the North American Plate.
