An earthquake wake up call — to the US

You don’t get any country better prepared for an earthquake than Japan. They know they are at risk, they are prudent, they have the money, the technology, and the work force; and yet, when hit by an earthquake of this magnitude, no matter how well prepared you are, you are in for some massive trouble.

It’s a well known fact that the San Andreas fault is way overdue for a major earthquake – an earthquake which will cause unthinkable damage, even though the state of California prides itself to be the leading edge in seismic technology. Very modern buildings have a fair chance of still standing, but everything other than that will become a carpet of rubble; after that, hot winds will undoubtably fan the fires that earthquakes always cause, pipelines will burst, and everything will be unstoppable.

San Francisco after the 1906 earthquake

California should learn from the Japan experience that no amount of preparation can make you ready for something like this, when a major earthquake is coming.

“Everybody is playing a gamble that something like this won’t happen,” said Dana Buntrock, associate professor of architecture, at the University of California, Berkeley.

The thing is, the 1906 earthquake in San Francisco left the city devastated; everybody wanted to rebuild as fast as possible, and so, numerous buildings were made without adequate reinforcing steel, while homes and apartment complexes are extremely vulnerable themselves.

“The question is not if but when Southern California will be hit by a major earthquake — one so damaging that it will permanently change lives and livelihoods in the region,” according to a 2008 study by the United States Geological Survey study.

A study concluded that a 7.8 earthquake will probably cause 2.000 deaths and $200 billion damage, but these kind of studies are always optimistic. A 7.8 earthquake would be about 30 times smaller than the seismic event that struck Japan, but it is unlikely to be over 8, due to the tectonic of the region – but then again, so was the Japanese temblor. The thing is, there is a 99 percent chance of a 6.7 magnitude quake within three decades, and 46 percent chance of a 7.5 or greater temblor – talk about good odds. The odds for a 8 to 9 earthquake in the next 30 years were only at 10 percent.

California and Japan tend to look at each other when it comes to building earthquake-resistant buildings, but Japan has a different strategy, of tearing down older buildings and building newer ones instead, which makes them better prepared for this kind of event. But California isn’t the only area which the US has to worry when it comes to earthquakes. Frank Vernon, a geophysics professor and seismology specialist at the Scripps Institution of Oceanography at UC San Diego, speaks about these dangers:

“The most important lesson in the U.S. and North America is the reminder that we have a similar subduction zone called Cascadia up on the coast of British Columbia, Washington, Oregon and very northern California which could do the same thing,” he said. “Some day we will be having this same type of earthquake near our shores,” he said.

This Picture of the Week shows a stunning spiral galaxy known as NGC 4945. This little corner of space, near the constellation of Centaurus and over 12 million light-years away, may seem peaceful at first — but NGC 4945 is locked in a violent struggle. At the very centre of nearly every galaxy is a supermassive black hole. Some, like the one at the centre of our own Milky Way, aren’t particularly hungry. But NGC 4945’s supermassive black hole is ravenous, consuming huge amounts of matter — and the MUSE instrument at ESO’s Very Large Telescope (VLT) has caught it playing with its food. This messy eater, contrary to a black hole’s typical all-consuming reputation, is blowing out powerful winds of material. This cone-shaped wind is shown in red in the inset, overlaid on a wider image captured with the MPG/ESO telescope at La Silla. In fact, this wind is moving so fast that it will end up escaping the galaxy altogether, lost to the void of intergalactic space. This is part of a new study that measured how winds move in several nearby galaxies. The MUSE observations show that these incredibly fast winds demonstrate a strange behaviour: they actually speed up far away from the central black hole, accelerating even more on their journey to the galactic outskirts. This process ejects potential star-forming material from a galaxy, suggesting that black holes control the fates of their host galaxies by dampening the stellar birth rate. It also shows that the more powerful black holes impede their own growth by removing the gas and dust they feed on, driving the whole system closer towards a sort of galactic equilibrium. Now, with these new results, we are one step closer to understanding the acceleration mechanism of the winds responsible for shaping the evolution of galaxies, and the history of the universe.
