Sinkhole drains lake near St-Louis, Missouri – Major Memphis bridge cracked – Is the New Madrid waking up?

Strange Sounds – May 13, 2021

Lone Elk Park in St. Louis County has a leaky lake — and an SUV-sized sinkhole that opened up there in recent days has drained about a third of it.

St. Louis County Parks Director Tom Ott said he got word Friday that the lake had dropped about 3 feet, and then enough water drained away over the weekend to reveal the sinkhole.

This isn’t the first time this has happened at the manmade lake, called the Lone Elk Reservoir, said Ott. In 2016, a similar sinkhole about 4 to 5 feet across appeared in the vicinity of the new one. Then, they had someone inspect it and had concrete slurry poured into the hole to patch it.

The county will get a hydraulic engineer to look at the sinkhole, and will send someone with a drone to take pictures of it. They’ll also add signage along the shoreline to warn people to keep away.

Ott wonders if a small-magnitude earthquake reported near Eureka on April 20 shook anything loose.

He said that in the early 1990s the lake was always full, but in the past 20 years it hasn’t held water the way it should. “We’ve had people look at it — they couldn’t tell where it was leaking,” he said.

Meanwhile, all lanes on the Hernando Desoto Bridge were closed Tuesday until further notice after an inspection found a crack that requires investigation.

Memphis Police said the bridge is being inspected, and it is unknown when the I-40 bridge will reopen. It could be closed for month…

Right now, drivers can use the Interstate 55 bridge to cross the Mississippi River.

Now, if you add to this giant sinkhole, the shutdown of the I-40 bridge in downtown Memphis due to infrastructure damage and the hacked (?) pipeline… Are these more signs of the overdue New Madrid earthquake?

California on seismic alert: Two shallow M4.6 and M4.4 earthquakes hit off Eureka within seconds – Precursors of the Big One?

Strange Sounds – April 2, 2021

Today morning, two shallow earthquakes (M4.6 and M4.4) hit off the coast of northern California at a depth of 8km and 19km, respectively.The pair of quakes struck 17 seconds apart of each other (8:21:18 and 8:21:35 AM UTC).Some weak or light shaking was probably felt in the Eureka and Fortuna areas.

The third M2.5 quake in the area hit 1 hour after the first two…

Meanwhile, I am sure geologists closely monitor the seismicity along the west coast…

These earthquakes could indeed be precursors of the next Cascadia Megathrust Earthquake or California Big One…

Indeed, the tremors occurred near the Mendecino Triple Junction, an area where the Cascadia Subduction Zone meets with the San Andreas Fault.

Moreover, if you look at the map from PSNS below, additional quakes rattled the Cascadia Subduction Zone off the Oregonian coast and on Victoria Island in Canada, as well.

An earthquake will destroy a sizable portion of the coastal Northwest.

The question isn’t if but when. And keep in mind: The next full-margin rupture of the Cascadia subduction zone will spell the worst natural disaster in the history of the continent.
