Since North Korea feels no need to provide infomation to the world...

...about it's missile launches, the FAA has to determine the tragectory of the missle before it allows flights out of the USA from the West Coast. They obviously knew as soon as the missle launched.

An unusual ground stop (click here) was issued to some pilots for a short period of time following a North American Aerospace Defense Command alert of a launch of a North Korean missile, a US official said Tuesday.

The official says it was not a national ground stop and may have been issued by a regional air traffic control facility.

“No warning was issued by NORAD HQ,” regarding a potential threat to the US, according to Captain Pamela Kunze, the chief NORAD spokesperson.

The Federal Aviation Administration, responsible for the nation’s air traffic control system, said the ground stop was to err on the side of safety.“

As a matter of precaution, the FAA temporarily paused departures at some airports along the West Coast on Monday evening,” the FAA said in a statement. “Full operations resumed in less than 15 minutes. The FAA regularly takes precautionary measures. We are reviewing the process around this ground stop as we do after all such events.”

The NORAD spokeswoman said the normal sequence following the launch was followed: The missile launch was detected, and it was assessed not to be a threat to the continental United States. The standard practice is for FAA to have a constant liaison in the NORAD ops center, therefore would have been aware of the quick assessment....

How special.

Creative and innovative.

Must have been a work of a genius.

It is a bird, no a plane, no North Korea's latest design in missile technology.

Seoul - North Korea tested a railway-borne missile (click here) in its firing drills on Friday, state media KCNA said on Saturday, amid a U.S. push for fresh sanctions against the isolated state following its recent series of weapons tests.

outh Korea's Joint Chiefs of Staff said two short-range ballistic missiles (SRBMs) travelled about 430 km (267 miles) to a maximum altitude of 36 km (22 miles) after being launched eastward on the northwest coast of North Korea....

Other than a big splash it isn't looking too bad.

Japan is having some quakes that I am confident the people are feeling and probably worried, but, the general region of the Pacific is quiet.

The volcano doesn't seem to have erupted with quakes occurring. It must have been from pressure deeper within the volcano itself.

Evacution away from the volcano would be prudent. My guess is that a Submarine Lava Dome (click here) exploded. That is an enormous pressure release.

The USA West Coast might have wave that are accompanied by a strong undetow and remaining out of the water is prudent. I would be surprised to have another big explosion, but, it is possible even if remote possibility.

Wellington, New Zealand - An undersea volcano (click here) erupted in spectacular fashion near the Pacific nation of Tonga on Saturday, sending large tsunami waves crashing across the shore and people rushing to higher ground. A tsunami advisory was in effect for Hawaii, Alaska and the U.S. Pacific coast, with reports of waves pushing boats up in the docks in Hawaii.

There were no immediate reports of injuries or the extent of the damage because all internet connectivity with Tonga was lost at about 6:40 p.m. local time — about 10 minutes after problems began, said Doug Madory, director of internet analysis for the network intelligence firm Kentik.

Tonga gets its internet via an undersea cable from Suva, Fiji, which presumably was damaged. The company that manages that connection, Southern Cross Cable Network, could not immediately be reached for comment.

In Hawaii, the Pacific Tsunami Warning Center reported waves slamming ashore from half a meter (1.6 feet) in Nawiliwili, Kauai, to 80 centimeters (2.7 feet) in Hanalei. “We are relieved that there is no reported damage and only minor flooding throughout the islands,” the center said, describing the situation in Hawaii....

What was the weather doing? Those circular clouds near the volcano are interesting. It doesn't look like a disturbance pattern.
