Japan's Big Earthquake: Why So Much News?One of the bits of wisdom that appears now and again in 'how to blog' advice is - remember that you're writing for a blog, not a newspaper. That's not as off-topic as it seems, in a post about Japan's mammoth earthquake.
Today's earlier 'earthquake' post about was mostly excerpts from news about the earthquake off the coast of Japan, near Sendai. This post will be pretty much the same, except that some of the information is from U. S. government agencies.
The Lemming isn't forgetting that this is a blog. The ratio of facts to commentary in these posts about the Japanese/eastern Pacific earthquake is heavy on facts, since the Lemming's quite interested in the event. The Lemming is also not at all certain how long NOAA archives their data. Or Wired - although Wired seems to be pretty good about not making their non-current articles hard to find. And that's another topic.
Here's what NOAA and Wired had to say about the quake:
Sendai/Japan/Pacific Earthquake: Map, Data, and a Different Magnitude"Message pacific.2011.03.11.223915"
Pacific Tsunami Warning Center, NOAA's National Weather Service (March 11, 2011
That's a NOAA (National Oceanic and Atmospheric Administration) page, with tsunami and earthquake information about the 05:46 UTC earthquake that hit Japan today. (March 11, 2011)
According to the page, the center of the quake was 24.4 kilometers, 15.2 miles, down at latitude 38.3° N, longitude 142.4° E.
The news has been reporting the magnitude of the earthquake as 8.9: which is the PTWC estimate. Looks like the USGS (United States Geological Survey) value for the earthquake's magnitude is 7.9: which is still a whacking great quake.
There's a map, showing earthquake's location. Also where a mess of other tremors were:

FOR ALL AREAS - WHEN NO MAJOR WAVES ARE OBSERVED FOR TWO HOURS AFTER THE ESTIMATED TIME OF ARRIVAL OR DAMAGING WAVES HAVE NOT OCCURRED FOR AT LEAST TWO HOURS THEN LOCAL AUTHORITIES CAN ASSUME THE THREAT IS PASSED. DANGER TO BOATS AND COASTAL STRUCTURES CAN CONTINUE FOR SEVERAL HOURS DUE TO RAPID CURRENTS. AS LOCAL CONDITIONS CAN CAUSE A WIDE VARIATION IN TSUNAMI WAVE ACTION THE ALL CLEAR DETERMINATION MUST BE MADE BY LOCAL AUTHORITIES. BULLETINS WILL BE ISSUED HOURLY OR SOONER IF CONDITIONS WARRANT. THE TSUNAMI WARNING WILL REMAIN IN EFFECT UNTIL FURTHER NOTICE. THE JAPAN METEOROLOGICAL AGENCY MAY ALSO ISSUE TSUNAMI MESSAGES FOR THIS EVENT TO COUNTRIES IN THE NORTHWEST PACIFIC AND SOUTH CHINA SEA REGION. IN CASE OF CONFLICTING INFORMATION...

Japan's Biggest Recorded Quake: 1/100 Death Toll of Last Big One"Earthquake Is Biggest in Japan's Recorded History"
Alexandra Witze, Science News, Wired Science, Wired (March 11, 2011)
(from NOAA, via Wired, used w/o permission)
"Image: A forecast for the tsunami caused by a magnitude-8.9 earthquake that struck off the coast of Japan on March 11, 2011. Heat-map colors show maximum tsunami height within the first 24 hours. (NOAA/PMEL/Center for Tsunami Research)"
"The magnitude 8.9 quake that struck off Japan's coast on March 11 will go down as one of the country's largest earthquakes.
"Even if its magnitude is downgraded in the coming days, as sometimes happens as more data are analyzed, the quake will remain a benchmark in a country that has seen many major quakes. It ranks fifth on the list of biggest quakes this past century. The Indonesian earthquake that spawned 2004's devastating Indian Ocean tsunami was a magnitude 9.1.
"Japan's monster earthquake struck at 2:46 p.m. local time, about 150 km off the coast of the island of Honshu. Japan is one of the world's most prepared societies when it comes to earthquakes, and a recently established early warning system broadcast alerts in many areas, including Tokyo, before the shaking began.
"Seismic activity in the region began with a magnitude 7.2 quake on March 3. Major aftershocks continue to rattle the area. The death toll is unknown...."
This could have been a lot worse. Back to the Wired article:
"...The deadliest quake in Japan's history came in 1923, when more than 140,000 people perished in the magnitude 7.9 Great Kanto Earthquake. That tremor was centered southwest of Tokyo Bay. The March 11 quake struck more to the north, offshore from the city of Sendai...."
The total death toll from today's earthquake may go higher than 1,000 - folks in Japan are still busy, looking for survivors. And non-survivors. To make the fraction come out very evenly, let's say it turns out that 1,400 people lost their lives in this disaster.
Comparing this to the 1923 quake, that's 1,400/140,000: or 1/100 the death toll this time. Maybe.
One reason the number is so low this time around may be what's being discussed in the news: Japan has been making a priority of studying earthquakes - and developing technologies and procedures for dealing with them - for the last several decades.
Looks like all that effort may have paid off.
Earthquakes aren't TornadoesWe don't get many earthquakes here in the upper Midwest. When we do, they tend to be big, and that's another topic. (July 30, 2010)
In this part of the world, its tornadoes that keep us on our toes. Among other things, like the sort of storm that's on the other side of the window at this moment. Yet another topic.
Bear with the Lemming, please: this really does connect to Japan's remarkable advances in earthquake tech.
Back in the Lemming's 'good old days,' the tornado warning system depended heavily on folks with a bit of training and really steady nerves deploying themselves where a tornado might develop. If they spotted one, they radioed in what they'd observed, and then tried to get out of the way. They were successful most of the time, happily.
Then we got radar that could 'see' inside those thunderstorms. We still have spotters: but these days there's satellite data, Doppler radar, and increasingly sophisticated software that quite often gives us several minutes to head for a shelter.
Folks in this part of the world don't get killed by tornadoes anywhere near as often as we used to. Which is one of the reasons the Lemming doesn't miss the 'good old days' all that much.
It's not that we're luckier today, than we were a half-century or so back. There's been a whole lot of new technology developed since the mid-20th century.
Which seems to be what's happened in Japan. Folks living there don't have to worry about tornadoes so much - but the same sort of change has made it possible for them to deal with earthquakes and tsunamis without so much loss of life.
