So apparently, the NYSlimes has decided to slam Pres. Trump for not wasting money on a silly-ass earthquake warning system.
(Moonbatville) People cannot prevent earthquakes, but they can take steps to minimize the deaths and damage. Many more might have died in Mexico City this week had the country not invested in an early warning system that rang alarms just before the catastrophic earthquake struck. The United States, which has been slow to finish a similar system on the West Coast, can learn from Mexico’s example.(Discussion of what an early warning system can do)As Pirate's Cove noted, it's not such a bright idea.
The United States Geological Survey is building a warning system called ShakeAlert for California, Oregon and Washington. A prototype is up and running. But Congress has not appropriated the money to finish it. Officials say just 40 percent of the necessary field stations have been built so far. The Geological Survey says that it would cost $38 million to finish the system and $16 million a year to operate it. Congress appropriated just $10.2 million in the current fiscal year. (California and private foundations have also contributed money to the project over the years.)
Let's do some maths, and since it's Saturday, I'll work it out for you.
P-waves radiate outward from an earthquake epicenter at 7 times the speed of sound in air (roughly 5300 MPH at sea level).
Love waves, the ground waves that do the actual damage, move outwards at a more sedate 700-1000 MPH.
IOW, in less than a minute, they've already arrived everywhere within 16 miles of the epicenter, or the nearest 860 square miles. In two minutes, the circle is 66 miles across, some 3400 square miles. Which is, for any foreseeable earthquake, the limit of anyone who cares, or needs warning.
Thus California, like everywhere else in the world, has a very precise earthquake warning system, and it costs zero dollars, with no annual maintenance fees:
If the ground shakes a lot, a dangerous earthquake is occurring.
If it doesn't shake so much, it's no big deal.
No warning system can secure more than a few seconds to perhaps a minute's notice faster than that, and anyplace with more warning will be so far away that the warning is useless.
And for a nominal optimum processing time of 15 seconds, anyone within 3 miles of the epicenter will never be warned before the ground is already shaking like a leaf in a hurricane.
Thus any warning system is a boondoggle, of a range from dubious to nil utility on its best day.
So the NYSlimes knows as much about earthquake physics as they do about anthropogenic global warming, or the lack thereof.
They are, in fact, idiots on a scale that should set off Stupidity Alerts - at seven times the speed of sound - every time they write about something.
Pretty much like every day for the last 50 years.
