Global rain accumulation for the next 10 days


The Noah Syndrome (October 24, 2012)
by Knight-Jadczyk, Laura


The human cost of disasters: (Deep State Global Agenda)
In the period 2000 to 2019, there were 7,348 major recorded disaster events claiming 1.23 million lives, affecting 4.2 billion people (many on more than one occasion) resulting in approximately US$2.97 trillion in global economic losses.

This is a sharp increase over the previous twenty years. Between 1980 and 1999, 4,212 disasters were linked to natural hazards worldwide claiming approximately 1.19 million lives and affecting 3.25 billion people resulting in approximately US$1.63 trillion in economic losses.

Much of the difference is explained by a rise in climate-related disasters including extreme weather events: from 3,656 climate-related events (1980-1999) to 6,681 climate-related disasters in the period 2000-2019.

The last twenty years has seen the number of major floods more than double, from 1,389 to 3,254, while the incidence of storms grew from 1,457 to 2,034. Floods and storms were the most prevalent events.

State of emergency in Sanharo, Brazil after nearly 6 months' worth of rain in ONE day


The city of Sanharo in Pernambuco, Brazil, has declared a state of emergency after heavy rains caused major flooding in several areas of the city on Monday, November 2, 2020. According to the state's water and climate agency (APAC), 288.8 mm (11.4 inches) of rain was recorded in a 24 hour period, which was equivalent to almost half a year's average.

Meteorologists said the amount of rain is unusual for the month of November, which is commonly a dry month. Around 300 people were left homeless after floods triggered by heavy rains hit Sanharo. This prompted the city government to declare a state of emergency and accommodated the displaced victims at gymnasiums and schools.

USGS has issued a warning about the renewed movement at the Barry Arm glacier in Alaska that could lead to a 'massive, catastrophic landslide into the Harriman Fjord ' and trigger a 'mega-tsunami'. This is partly to due to the mass of material as well as the shape of the fjord itself.

In October NASA published an article warning of the above possibility because the glacier had begun to move for the first time since 2015.

The article and alert are posted below.

Notably they report that the slip began about 50 years ago but sped up between 2009 - 2015. And back in May of 2020 "a group of 14 scientists published an open letter warning that a landslide-generated tsunami is likely within 20 years and could happen at any time."

Throughout October they measured a movement of 8inches whilst between 2009-2015 it moved 600 feet.

As a reminder, on 17th October a strong magnitude 7.5 earthquake struck Alaska - now, whether that has had any effect on the movement, or it will, or whether it's indicative of what's going on around there, i don't know.






Landslide induced mega-tsunami 'could happen at anytime' at Alaska's Barry Glacier

Barry glacier June 2019
While kayaking in Barry Arm fjord in June 2019, Valisa Higman, an artist-in-residence at Alaska's Chugach National Forest, noticed some odd fractures on a cliff overlooking the fjord. Curious if the slope might be in the process of collapsing, she emailed photos (see one of them below) to her brother, Bretwood Higman. "Hig" is a geologist with Ground Truth Alaska, and he has studied landslides and tsunami deposits for decades.

He was soon inspecting the area using Google Maps, zooming in to the maximum extent possible and searching for signs of slippage. He saw the cracks as well, but nothing about them struck him as strong evidence of a big landslide. "But it turns out I had made a geology 101 error," he said. "I hadn't zoomed out enough, and I missed the big picture." Still, he kept Barry Arm on a list of possible landslides to investigate more someday.

A few months later, Chunli Dai offered that chance. The Ohio State researcher was working on a NASA-funded project to develop new ways to automatically detect landslides in the Arctic, and she was looking for test sites to check how well the tool was working. Her project makes use of a high-resolution dataset called ArcticDEM and machine learning to automatically search for and flag landslides.

When Dai used her tools to survey the Barry Arm area, she got some eye-popping results — an entire mountainside near Barry Glacier was slowly and subtly shifting. If the giant, slow-moving landslide were to suddenly collapse into the narrow fjord below, it would generate an extremely large tsunami because of the way the fjord's shape would amplify the wave.

"It was hard to believe the numbers at first," said Dai. "Based on the elevation of the deposit above the water, the volume of land that was slipping, and the angle of the slope, we calculated that a collapse would release sixteen times more debris and eleven times more energy than
Alaska's 1958 Lituya Bay landslide and mega-tsunami." That event, which was triggered by a 7.8 earthquake, dropped millions of cubic yards of rock about 2,000 feet (600 meters) into a fjord. It produced what is thought to be the tallest wave (1,700 feet) in modern history. In an event that eyewitnesses compared to an atomic bomb explosion, the huge wave washed away soil in a wide ring around the bay and obliterated millions of trees.

Yet Higman and several of Dai's colleagues were initially skeptical that there actually was a slide in Barry Arm. The size of the landslide Dai was reporting was enormous — far bigger than any other known landslides in Alaska. Her detection technique was new and untested. And in some other areas, the presence of snow cover, shadows, or clouds caused the tool to erroneously label features in satellite images as landslides when they clearly were not.

But Dai kept looking and checking other types of satellite data, including a decades-long series of Landsat images of Barry Arm via Google Timelapse. When she scrutinized 2013 and 2016 satellite images of the area, it became abundantly clear that her ArcticDEM results were real.

"With the wider perspective from Landsat, the movement of the slope was impossible to miss," she said. "You can see a whole section of the mountain between Cascade Glacier and Barry Glacier slumping toward the water." (In the Landsat images at the top of this page, use the slider to see the movement for yourself.) The slope moved forward by about 400 feet (120 meters) between 2010 and 2017. Since 2017, it has moved very little.

[You can find the slider imagery here.]

Immediately after seeing the Landsat images, Higman was also convinced something serious was happening and alarmed about what it could mean. Since then, he has been reaching out to colleagues and coordinating with state and federal partners to evaluate the risk. In May 2020, a group of 14 scientists published an open letter warning that a landslide-generated tsunami is likely within 20 years and could happen at any time. If a landslide occurs, the resulting tsunami in BarNASA Earth Observatory images by Lauren Dauphin, using Landsat data from the U.S. Geological Survey. Story by .ry Arm could produce waves that are hundreds of feet high. Other, more distant bays — such as the more heavily populated Passage Canal (about 30 miles/50 kilometers away) — could see 30-foot (9-meter) waves.

By looking back at older satellite images and aerial photographs, the team of scientists has determined that slippage in this area is nothing new. They think the slope began to shift at least 50 years ago, but it appears to have sped up between 2009 and 2015, just as the front of Barry Arm glacier was retreating. "The slope probably sped up because the glacier that had been supporting the bottom of the slope retreated," explained Higman. "When warming temperatures caused that ice to retreat, the slope was free to move."

The open letter prompted new monitoring projects at the U.S. Geological Survey, the Alaska Department of Natural Resources, and the National Atmospheric and Oceanic Administration. Researchers are now working to track the slope's motion with synthetic aperture radar on satellites, aerial lidar, and aerial photography. Other scientists are setting up gauges to detect tsunami waves in advance. And others are working to make better maps of the bathymetry (shape of the seafloor) of the fjord to more accurately model how a tsunami might move through it.

"We have learned a tremendous amount about this hazard, and I think we have done a good job of getting the word out about it," said Higman. "But there are still a lot of really interesting and important scientific questions that we are only barely starting to investigate." For instance, why did the landslide stop slipping in 2017 and does that mean it is less likely to collapse in the short term? Also: can we expect to see a sharp increase in this type of hazard as more and more glaciers retreat?

"These are fairly unusual events, and scientists have only started studying the connections between glacial retreat and landslide tsunamis in the past few decades," he said. "We don't have a very long or deep record to look at yet."

USGS alert:

For Immediate Release: November 10, 2020

Satellite imageryshows renewed movement of Barry Arm landslide(Anchorage, AK) – New satellite imagery has shown renewed movement of a large landslide along the Barry Arm of the Prince William Sound 28 miles northeast of Whittier, Alaska.

The U.S. Geological Survey measured 8 inches of downslope creep between October 9 and October 24. It is the first detected movement of the landslide since active monitoring began May 26, and was achieved by comparing earlier Interferometric synthetic aperture radar (InSAR) satellite imagery with more recent satellite data. While the National Tsunami Warning Center has no current indication a catastrophic landslide failure and tsunami are imminent, landslides are unpredictable. Communities throughout Prince William Sound need to remain vigilant, and mariners should strongly consider avoiding areas near Barry Arm and Harriman Fjord. For more information on tsunami warning and response, go to the National Tsunami Warning Center. Retreat of the Barry Glacier has removed support for the hillside, which slid 600 feet downslope between 2009 and 2015. Geologists and geophysicists are concerned a massive, catastrophic landslide into the Harriman Fjord could trigger a tsunami that would threaten local communities. An interagency science team comprised of state, federal and other scientists has been monitoring the situation.

“We ask that everyone continue to avoid this part of Prince William Sound,” said Alaska’s Division of Geological and Geophysical Surveys Director Steve Masterman. “We take this threat seriously and encourage those in the Sound to have a plan in case of tsunami.”

State and federal agencies continue to monitor the situation and will keep the public informed about ongoing efforts and important updates.Current information is available at the Barry Arm Landslide and Tsunami Hazard

Heavy rains hit the #Guadeloupe . Basse-Terre was the most affected with local accumulations of up to nearly 200 mm in 24 hours! (via
@MeteoFrance_AG ) 7:34 AM · Nov 11, 2020· France

New alerts have been issued for Florida’s Gulf side where tropical storm warnings and a storm surge watch are now in effect as Eta will affect the area by Thursday.

The latest intensity forecast now has Eta remaining at Tropical Storm strength through the week as it moves through the eastern Gulf of Mexico and now makes another landfall north of Tampa and eventually tracking over Gainesville in Northern Florida by the weekend.

With the Security Cabinet and the state governor, we are addressing the problem caused by the floods and supporting the victims of Tabasco.

.@Agricultura_mex He remarked that “the relationship of damages to crops, livestock and productive infrastructure will be announced once the corresponding evaluation is made, which is carried out, in the case of floods, after the water drops

Last week the three Central American countries suffered the onslaught of Eta, which struck Nicaragua as a category 4 hurricane and left more than 200 dead and millions of dollars in damage to homes, roads and crops.

Peat landslide/landslip caught on video at a windfarm in Donegal, northern Ireland, and below is an article about the incident by the Daily mail.

It seems to be a rare occurrence with a local Councillor stating he wants to know how it happened.

It seems possible that both Earth Changes and wind turbines, that are destructive at the best of times, could've combined and caused this to happen.

It's around the 30 second mark that it becomes clear what's happening. Quite an odd sight with the trees just casually sliding by.


Amazing moment trees on hillside slide down slope after peat slippage on windfarm in Northern Ireland​

  • A passerby was stunned to see an entire landscape move in front of his eyes
  • The unsettling incident was the result of a peat slippage in Northern Ireland
  • There were no reports of injury or concerns the local water supply affected
Published: 17:23 GMT, 15 November 2020 | Updated: 17:23 GMT, 15 November 2020



This is the startling moment an entire landscape moves from one side of a hill to another during a peat slippage in Northern Ireland.

The unsettling incident was witnessed by a surprised passerby and caught on camera, as a number of mature trees rapidly glided down a slope at Meenbog Wind Farm, just south of Ballybofey, on Friday afternoon, according to Buzz.

While there were no reports of injury or concerns that the local water supply could be affected, one councillor said 'there are serious questions about how this happened.'

Rain theory

With all this rain worldwide, you'd think meteorologists would have an explanation for the escalating amounts coming down.

So, the sun is the first explanation. And that might seem obvious and no other explanation is necessary.

But with other strange happenings, like world pandemics, loud noises in the atmosphere, sink holes, ect. And the permafrost melt and methane release threat...

Maybe it's the methane threat we been hearing warnings from the scientists about. And the thing about what they warn us about, they don't go into how this methane release actually manifests. They mostly are inclined to advise governments and not go into what will actually take place.

So, I remember a old man telling us youngsters about natural gas... he said you don't really need to pipe the natural gas exhaust outside for fear of poisoning, because it burns clean. You pipe it out the chimney because it creates moisture.

So, that could explain the rains. And as well, with permafrost melting, landmasses settle, and so we'd witness cities settling, ect. making what is going on seem biblical, but it is a combination of factors stacked on another: ice melt, rain from methane, earth sinkage, even erosion escalating the whole matter.

It would make sense that permafrost can sustain for so long after an ice age, because it is insulated by earth and where does cold go? It sinks. Heat rises. Cold sinks. As well, when water freezes, it expands. When it melts, the earth settles.

So, that's my theory about the rains. And we are left to figure it out for ourselves, lest we seem alarmist. And our civilisation is in the midst of it all - with most of the populations near water, and that furthers the necessity of discretion.
