Russia: First an Under Ocean 8.8 Earthquake – Then a Volcanic Eruption

Latest: Klyuchevskoy Volcano in Russia Starts Erupting

The Klyuchevskoy volcano on the Kamchatka peninsula in Russia’s far east has started erupting after Wednesday’s powerful earthquake in the Pacific, Russian state news agency RIA reported, according to Reuters.

The volcano is known to be the tallest active volcano in Eurasia.

The massive quake struck on Wednesday morning in Russia, generating a tsunami of up to 4 metres (13ft) on the country’s east coast, damaging buildings and prompting evacuation warnings in the region and across most of Japan’s east coast, officials said.

First the 8.8 Earthquake

A powerful magnitude 8.8 earthquake off Russia’s far eastern Kamchatka Peninsula triggered tsunami waves of up to 5 metres (16 feet) nearby and sparked evacuation orders as far away as Hawaii and across the Pacific on Wednesday.

The tsunami wave swept away buildings on the coastal area of Severo-Kurilsk, the main settlement on Russia’s Kuril Islands in the Pacific. The regional authorities declared a state of emergency but mayor Alexander Ovsyannikov said all residents were safe and had been evacuated. The country’s emergency ministry said parts of the town had been flooded. The tsunami alert was later cancelled in Russia’s Severo-Kurilsk, state-owned Tass news agency reports.

More than two million people were evacuated in Japan, including workers at the stricken Fukushima nuclear plant in northeast Japan, who were evacuated, with plant operator Tepco saying that “no abnormality” had been observed at the site.

Japan later lifted all tsunami warnings, downgrading them to a tsunami advisory, Reuters reports, citing the Japan Meteorological Agency.

Broadcaster Asahi TV reported a 58-year-old woman died when her car fell off a cliff while she was evacuating in central Japan’s Mie prefecture, Reuters reports.

Hawaii downgraded its tsunami warning to advisory and lifted its evacuation order with people able to return to their homes.

The Klyuchevskoy volcano on the Kamchatka peninsula in Russia’s far east has started erupting after Wednesday’s powerful earthquake in the Pacific, Russian state news agency RIA reported, according to Reuters.

Authorities in Central and South America have ordered evacuations and issued tsunami warnings.

Tsunami waves began hitting the Marquesas Islands in French Polynesia early on Wednesday, but the waves were forecast to be smaller than initially feared, local authorities said.

The National Tsunami Warning Centre (NTWC) said a tsunami advisory has been cancelled for coastal areas of south Alaska, the Alaska peninsula and the Aleutian Islands from Chignik Bay, Alaska to the Samalga Pass.

The NTWC said a tsunami advisory has been cancelled for the coastal areas of British Columbia from the Washington/British Columbia border to the British Columbia/Alaska border. A tsunami advisory is now cancelled for American Samoa, Reuters reports.

Sargassum Seaweed Bloom Back Overrunning S. Florida Beaches

Seaweed is invading South Florida beaches again this summer. From Miami Beach to Ft. Pierce, Florida, the sargassum bloom has impacted beaches with up to shin deep stinky weed.

It’s caused by fertilizer runoff and pollution in the Atlantic Ocean and greatly impacts the Caribbean and Florida beaches. Since I reported on the first major Sargassum Seaweed bloom over 10 years ago, we’ve had a couple times that was almost this bad. Hopefully it won’t get as bad as the first:

Florida Sheriff Warns Beachgoers to Ignore Bizarre Clumps of Manatees Near Shore

The Pinellas Sheriff’s Office shared a warning on June 15 after receiving numerous calls about groups of manatees gathering together

Manatee Mating

If you see the manatees rocking through the waves, don’t come knocking on the Pinellas Sheriff’s Office’s door.

The Florida sheriff’s office shared an unusual warning about the animals on Instagram on June 15. The post includes a video showing a clump of manatees closely gathered together on the shore of a Florida beach. At least 10 manatees swim over and near each other in the footage.

According to the post, this type of bizarre-looking manatee gathering is common in the summer, and no cause for alarm. The marine mammals are getting together for an NSFW reason, per the Pinellas Sheriff’s Office.

“If you see this … no, you didn’t,” the sheriff’s office wrote on the manatee video. “Don’t call us. They are more than fine. It’s mating season.”

Pinellas Sheriff’s Office provided more context in the caption alongside the manatee footage.

“We get calls all the time from citizens when they see this, believing the manatees are in distress. We can assure you they are more than fine,” the agency wrote, adding, “Manatees actually mate in herds like these, and often they are near the shore. They mate all throughout the year, but generally, mating herds like these are seen in the summer months.”

Disturbing Footage of Seaweed Overtaking this Popular Beach!

So far it’s not as bad as 2019 in Palm Beach County. But, it’s pretty bad. The Sargassum bloom is out of control again. This is in Ocean Ridge, Florida.

Sargassum is a seaweed that can accumulate along the shoreline in large amounts, making the shoreline inaccessible for swimming, boating, and other recreational activities. This beach seaweed overflow is happening again.

If you live near the coast and have experienced the beach seaweed overflow in the past, then you already know what to do! Be sure to check out our site for more information on this and other coastal issues!

See the feature story I did in 2019 when it was really bad in Florida, the Caribbean, and South and Central American coasts:

Shark Attacks in U.S. Total 28 So Far This Year

Unprovoked bites, while rare, have been raising the alarm for some beachgoers this summer

Sources: Florida Museum of Natural History (1837-2021); trackingsharks.com (2022 data from media reports)

Brownie Bytes Take: As a surfer with 40 years experience in Florida, New Smyrna Beach has the most shark bites and sharks in the surfline than anywhere else. I’ve been bumped, chased, and seen others bitten there in 3 ft. of water right along the shore. Even though the blacktip shark migration during the late Fall and Winter happens in S. Florida with 10,000 sharks per mile per day cruising near the coast, they rarely bother anyone.

– R. Michael Brown

News of shark attacks off the coast of New York’s Long Island this summer raised the alarm for many beachgoers, surfers and divers. Shark bites, although rare compared with the number of people who get into the ocean, still happen in coastal areas of the U.S.

According to Tracking Sharks, a website that specializes in reporting shark attacks and bites across the globe, there have been 28 shark attacks in the U.S. in 2022 as of Aug. 1. Two of the attacks were provoked and none was fatal.

There were 47 confirmed cases in 2021, returning to prepandemic levels, and 33 in 2020.

Unprovoked shark bites are the most common incidents, according to the Florida Museum of Natural History’s International Shark Attack Files, a global compilation of all known shark attacks. Florida leads the U.S. in shark attacks, followed by Hawaii, California and South Carolina.

The most frequent type of unprovoked bites are so-called “hit and run” attacks, the museum says. These normally happen in the surf zones as coastal shark species follow schools of fish close to shore. There, sharks can encounter swimmers and surfers—and sometimes confuse people with their usual prey. The sharks don’t return after inflicting a single bite or slash wound.

Shark attacks and deaths from shark bites are extremely rare, experts say. The yearly average of unprovoked shark bites globally is 70, resulting in about 5 deaths, data from the Florida Museum of Natural History shows.

Where Are Those Shoes You Ordered? Check the Ocean Floor | WIRED

More containers have fallen off ships in the past four months than are typically lost in a year. Blame heavy traffic and rolling waves.

SINCE THE END of November, this is some of what has sunk to the bottom of the Pacific Ocean: vacuum cleaners; Kate Spade accessories; at least $150,000 of frozen shrimp; and three shipping containers full of children’s clothes. “If anybody has investments in deep-sea salvage, there’s some beautiful product down there,” Richard Westenberger, chief financial officer of the children’s clothing brand Carter’s told a conference recently. 

You can blame the weather, a surge in US imports tied to the pandemic, or a phenomenon known as parametric rolling.

All told, at least 2,980 containers have fallen off cargo ships in the Pacific since November, in at least six separate incidents. That’s more than twice the number of containers lost annually between 2008 and 2019, according to the World Shipping Council.
