Sony, Subaru, and Toyota close factories in wake of earthquake, other companies check in
Our thoughts this morning are with the folks in Japan and the other Pacific areas affected by the massive 8.9 earthquake that struck about 230 miles East of Tokyo. Reports of damage are flooding in from the country, and indeed many familiar manufacturers are checking in. Sony and Toyota have both stopped operations in their factories due to damage. Tragically, one Honda worker lost his life after a wall collapsed, while several Panasonic workers are said to have suffered minor injuries. It remains to be seen exactly what impacts this will have on consumers, but Sony's closed factories were responsible for the production of Blu-ray discs and batteries, while the numerous automotive shutdowns could result in short-term shortages. This bad news sent stocks downward, with German share prices for Sony dropping 2.5 percent and Honda 4.5 percent. We're still watching with concern to see what other impacts the resultant tsunamis could have, but for now we'll keep hoping for the best. Update: Some further news from Smarthouse, which indicates that Sharp's new 10G LCD plant in Sakai City shut itself down automatically upon first signs of a quake. Hooray for technology.
Google reacts to Japanese tsunami with a Person Finder tool
Now this is the sort of activity you'd expect from a true search giant. Instead of sitting on its hands during the tsunami that has stricken Japan today, Google has put together a Person Finder tool where people worried about the plight of their loved ones can look them up by name. There are only a few thousand records up on the site at the moment, but it should still be a useful repository for missing person data, particularly since mobile networks were taken down by the tsunami's damage earlier this morning. Information should also start piling up as recovery efforts continue. Let's just hope this Person Finder won't have to be used for too long and things can be brought back to normal soon.
Researchers propose using undersea internet cables to detect tsunamis
We've heard of a few inventive ideas for detecting tsunamis, and it looks like a group of researchers from the National Oceanic and Atmospheric Administration (or NOAA) have now come up with another: put all those undersea internet cables to a second use. While they haven't moved beyond computer models just yet, the group has apparently found that voltmeters attached to the end of an undersea cable are able to detect the small electric field stirred up by tsunamis, which measure around 500 millivolts. As New Scientist reports, however, the idea does have some considerable limitations, including that it wouldn't be able to pinpoint the exact location or direction of a tsunami, and that any such system would first need to filter out noise caused by other natural events and even the cable itself. Other researchers also caution that it's just as important to develop a system to quickly pass on a warning to potentially affected areas once a tsunami has been detected.
Japan's earthquake warning system tested out
It's a good thing that Japan's Meteorological Agency actually had the nationwide earthquake warning system ready to rock in March, as the fiber optic system was put into use this month in an attempt to warn citizens of an imminent tsunami. Reportedly, a "huge tremor" struck and triggered the system, which allowed warnings to be beamed out en masse "within a single minute." Although the system was tested before in false alarm fashion, this was the first time it had been used in a legitimate emergency, and it beat the previous options "by around one to two minutes." Sadly, it still wasn't quick enough to save everyone from the 6.9-magnitude quake, as 170 people suffered various injuries while one individual passed away, but the statistics could've been much worse had the speedy system not kicked in at all.
Tsunami alert! A3M shows off SMS warning system at CeBIT
A3M has your back if you should find yourself traveling in an area at risk of a tsunami. This clever group has its fingers in research stations all around the globe, constantly checking reports of underwater seismic activity. If a seismic event occurs, all subscribers in the affected area will receive 3 SMS flash messages in a row warning of impending doom. Subscription pricing comes in a few different flavors: one year subscription for $40, one month for $13, and a bulk package with 5 to 1000 users. The idea behind this is sound, and if it saves lives, we are all for it -- but we can't help worry that if your subscription expires or you are out of a coverage area, you could be up the creek.
P2P software uses hard drives to detect, warn of tsunamis
News outlets and weather stations alike have been searching for more responsive (and foretelling) methods to detect massive storms before they make landfall, and it seems a simple hard drive or two could help out substantially. While certain folks have tried to get fancy and implement mobile warnings to alert citizens of incoming tsunamis, Michael Stadler has devised a P2P software solution that uses plain 'ole hard drive vibration detectors to not only keep the read / write heads aligned, but to feed analytic software those same quaking measurements. By having numerous supernodes compare vibration levels, the software can reject false alarms and substantiate actual threats based on the uniformity of the data -- if an actual tsunami looks to be rushing inward, all connected clients could be immediately informed to brace for impact. While Stadler's software is still in an "experimental stage," it recently caused quite a stir at the Ars Electronica exhibition, and could probably entice a few proactive governments to fund future development.
