Two earthquakes hit Saturday near Government Camp, Oregon, one of them topping out at magnitude 3.9.

The tremors were strong enough for some locals to feel it, The Oregonian reported.

The earthquake rumbled at 8:51 p.m. June 5, just south of the summit of Mount Hood. It was preceded by several earthquakes in the hour before the quake, and tens of aftershocks have occurred since, the Cascades Volcano Observatory of the U.S. Geological Survey reported in a news release Saturday night.

The volcanic action and location are consistent with past swarms in the Mount Hood area, including a magnitude 4.5 on June 29, 2002, that was located about 1 mile east of Saturday's ground shaker.

Aftershocks will likely continue for hours or days, some of which may be felt, according to the news release.

Comment: A few days ago a significant earthquake swarm hit southern California.

In the past few days, the rainfall in Zhuhai, Macau and Hong Kong has been almost the same. Zhuhai was completely flooded, roads turned into oceans, and cars were submerged in water. However, there were only a few very minor local floods in Macau and Hong Kong. why?

In the beautiful coastal city of Zhuhai, residents have been in a state of water shortage since 2021. It rains and there is water, but the weather is sunny and dry - lack of water. Santang Village, Hengqin New District. In the absence of tap water, villagers and families use nearby mountain spring water for drinking. Since May, the village has been without water for several days due to the hot and dry weather. The authorized person tried to use water trucks to solve this problem.

Suspected megacryometeor crashes through Wisconsin home, nearly hitting resident

megacryometeor
Imagine trying to get up and get ready for your day but instead of having to shut off your alarm clock, you are greeted by a cannonball-sized chunk of ice.

While Mother Nature can be known for some pretty interesting weather, this strange icy incident left one Elk Mound family with a large hole right above their bed.

A large ball of ice, weighing 12.6 pounds, crashed through the bedroom ceiling.

Website Strange Sounds has documented a number of other similar events in California, Scotland, Italy, and India.

As for the cause behind this phenomena, Wikipedia notes:
A megacryometeor is a very large chunk of ice which, despite sharing many textural, hydro-chemical, and isotopic features detected in large hailstones, is formed under unusual atmospheric conditions which clearly differ from those of the cumulonimbus cloud scenario (i.e. clear-sky conditions). They are sometimes called huge hailstones, but do not need to form under thunderstorm conditions. Jesús Martínez-Frías, a planetary geologist and astrobiologist at Institute of Geosciences (Spanish: Instituto de Geociencias, IGEO) in the Spanish National Research Council (Spanish: Consejo Superior de Investigaciones Científicas, CSIC)[1] in Madrid, pioneered research into megacryometeors in January 2000 after ice chunks weighing up to 6.6 pounds (3.0 kg) rained on Spain out of cloudless skies for ten days.

Formation

The process that creates megacryometeors is not completely understood, mainly with respect to the atmospheric dynamics necessary to produce them. They may have a similar mechanism of formation to that leading to production of hailstones.[4] Scientific studies show that their composition matches normal tropospheric rainwater for the areas in which they fall. In addition, megacryometeors display textural variations of the ice and hydro-chemical and isotopic heterogeneity, which evidence a complex formation process in the atmosphere.[5][6][7] It is known that they do not form from airplane toilet leakage because the large chunks of ice that occasionally do fall from airliners are distinctly blue due to the disinfectant used (hence their common name of "blue ice").

Some have speculated that these ice chunks must have fallen from aircraft fuselages[4] after plain water ice accumulating on those aircraft through normal atmospheric conditions has simply broken loose. However, similar events occurred prior to the invention of aircraft.[8][9] Studies indicate that fluctuations in tropopause, associated with hydration of the lower stratosphere and stratospheric cooling, can be related to their formation.[5] A detailed micro-Raman spectroscopic study made it possible to place the formation of the megacryometeors within a particular range of temperatures: −10 to −20 °C (14 to −4 °F).[10] They are sometimes confused with meteors because they can leave small impact craters.
And, indeed, there are many signs in our skies that our atmosphere is undergoing a shift towards cooling:

An evacuation order remains in place for homes in New Remo, B.C., pictured, along the Skeena River.
Multiple properties along the Skeena River have been evacuated in northwestern British Columbia, amid rising floodwaters.

The Regional District of Kitimat Stikine has declared a local state of emergency for parts of Electoral Area C, and issued evacuation orders for all properties in New Remo, west of Terrace, and all properties in Old Remo, past the intersection of Old Remo Road and White Bottom.

On Friday afternoon, an evacuation alert for Dutch Valley was upgraded to an evacuation order.

RCMP said a 73-year-old man was found dead in a flooded basement of a home in the 6700-block of Kilby Road in New Remo, inside the evacuation zone, and that the death was "likely" related to the high river.

B.C.'s River Forecast Centre has issue flood warnings for the Skeena Rive above the Babine River, the Stikine River and its tributaries, and the Tuya River.

Houses, paddy fields and roads have been inundated in parts of Sri Lanka after days of heavy rain.
The death toll from floods and mudslides following heavy rains in Sri Lanka has risen to 14 with another two reported missing.

Ten districts on the island have been under heavy rainfall since last Thursday, including the capital Colombo and suburbs where many houses, paddy fields and roads have been inundated.

Ten people have died in floods while another four lost their lives in mudslides, according to the government's Disaster Management Centre.

Among them was a family of four who died when a mound of earth crashed onto their house in Kegalle district, about 85km east of Colombo.

Two others remain missing.

Sri Lanka's navy said it had deployed 33 teams to flooded areas, which so far have rescued 66 people stranded by the floodwaters.

The centre said the extreme weather has affected some 245,000 people, and more than 4300 remain displaced in emergency shelters. More than 800 houses have been damaged.

Experts are perplexed by an illness afflicting local birds where their eyes crust over and cause other neurological symptoms
An unusual number of birds are suddenly going blind and dying in the area around Washington DC, puzzling wildlife experts.

DC resident Alexandra Dimsdale found a young grackle stumbling around outside her home on Saturday.

After taking it to City Wildlife, a rehabilitation centre in the northwest part of the capital, she told The Washington Post that a member of staff said there was nothing they could do. She learned that the bird probably had some kind of neurological illness, causing it to go blind.

Comment: It remains to be seen what is afflicting the young birds but that it seems to be confined within a particular locality and to certain species and age is notable. In recent years there have been numerous reports of birds suffering due to starvation, illness, as well as mysteriously dying en masse:

Threat of flooding in coastal Louisiana and Texas after waterlogged spring

The Weather Service's forecast for heavy rainfall

The Weather Service's forecast for heavy rainfall.
If you live along the western Gulf of Mexico coast, odds are that this spring had you ready to build an ark. Some parts of Texas and Louisiana have seen more than 2½ feet of rainfall since the start of April, and more is on the way.

Another three to six inches of rain, and maybe more in spots, is set to target already waterlogged areas through early next week. Flash flood watches are in effect for much of the Louisiana coastline.

In Texas, numerous rivers and streams have overtopped their banks due to recent rains, prompting flood warnings for waterways in the zone from around Victoria to Beaumont.

Signs also point to a continued wet and rainy pattern over the upcoming week and a half, with continued bouts of rainfall set to renew flood concerns.
