^Thanks for your profound insights on geology !
As unrelated as Berlusconi's stopped funding for seismic activity research (but right tool for predicting earthquakes): ![]() |

@kanz if it was that easy to predict an earthquake no one would ever die again ,but seeing as there is no way to predict an earthquake ,(watching some pressure sensors in a mine are completely different to trying to predict an earthquake), or even have an idea how big one would be, people are always going to be caught out when one happens ,and all this stupidity has done is ensure scientists Wont make any comments or warning for fear of being sent to jail if there's a different outcome ,and more people will probably die now because of it.

1. You cannot predict an earth quake.
2. You cannot predict a Tsunami caused by an earth quake, due to #1. What the scientists probably meant was that you cannot do anything than moving away anyway, so you can as well 'take a glass of vine'. This is not cynical, but common sense. Anyone wo settles in a geologically active area has to live with the possibility of earth quakes. There is no one to blame but life (and death) as such. OT regarding Berlusconi: It sure did not help that Mr. Berlusconi stopped the funding for the seismic research, but even then the scientists would not have been able to predict this. But. 1. At the time of the earthquake Mr. B. was head of the state. 2. A few years before he had stopped funding all kinds of scientific state research to make up for the economical downfall, including the rescue of classic monuments in Rome, and seismic activity studies. Sure he does not want to make this public. 3. Almost all bigger media in Italy belong to Mr. Berlusconi. 4. One of the judges related to those court decisions may have been invited personally, to Mr. B.'s 'Bunga-Bunga' parties. 'Democracy' at work. Make of that what you want. |

People need to understand that the best math and science is "inexact".
You know how on the weather report, they always say "percent of precipitation"? Its only a percent, its not exact at all. It is impossible for anyone to know exactly. it is only a statistic. |

By this definition, our Michael Fish, the weather forecaster who denied that there would be a hurricane (although technically he was right, it wasn't a hurricane and he DID say it would be very windy) just before the 1987 storm which killed 22 people should have been jailed.
Your comparison to your fathers job watching a gauge is inaccurate, because if the dial moves too far, then he calls in the other guys and they make the assessment to evacuate the mine or not (Presumably) but as any geologist or vulcanologist that works in the public eye will tell you, they face a catch-22 situation whenever a scenario presents itself where there is a possibility that an earthquake may occur or a volcano may erupt, because there is a 50/50 chance of it happening. Now, if they sound the alarm, the area is evacuated, businesses close, the economy is effected and people have to leave belongings behind. Now, if the earthquake happens or the volcano erupts then all well and good, people have been saved, the geologists and vulcanologists are hailed as heroes and the rebuilding begins...but if nothing happens, then the geologists and vulcanologists are accused of scaremongering, and no-one listens to them. Sometimes they can come under a lot of pressure from government officials NOT to declare a situation because of the effect it would have on the economy and the chance that it might not come to pass. A swarm of earthquakes in an area can be an indication of a future major earthquake, or it can just be a fault line letting off steam, there is no way to tell until it happens. Even Japan, which has the best earthquake detection system in the world, with over a thousand seismographs employed, could only give a minutes warning before the 2011 Tohoku earthquake and subsequent tsunami. Scientists in Japan had predicted that the 'Big One' which they anticipated would occur at some point in the future, would occur further south towards Tokyo but they couldn't be sure where it would happen until it happened. Earthquakes and volcanoes are very hard to predict accurately, although volcanoes are a bit easier than earthquakes as they show more visible signs of an eruption than earthquakes do, but we are getting better at earthquake prediction than we were even twenty years ago, but it's still not an exact science, and for Italy to jail these men for making a bad call is absolute nonsense and I don't blame the head of the Italian disaster organisation for resigning in protest, it's going to set a dangerous precedent when Italian seismologists will be more concerned with their public appearance than potentially getting a warning out, if anything it's going to make them more reluctant to commit to a yes or no, and put the Italian people at more risk. |

What a bum rap for those guys. I used to live in Washington State which has both seismic and volcanic activity it is much easyer to predict the latter as like Oberon said volcanos do tend to give warning signs before an eruption. As for earthquakes its is far more difficult to predict when a "big one" will happen. There have been many predictions as to when the next big quake will happen, sometimes these predictions are correct but more often then not they're wrong. The major trouble with predicting any sort of major earthquakes is that by the time a warning is given the quake would have started or have already ended. While I was living in Washington State I had the experiance to have lived through an earthquake which was the 2001 Nesqually quake (magnitude 6.8) and the quake lasted only 45 seconds and there was no warning. It is a great injustice to throw these seismoligests into prison on the basis that they failed to predict what no human nor machine can.

They should hang the judge for not predicting that these scientists were going to commit manslaughter.

yup, it's a great injustice that someone has to face the consequences of his bad decisions. If it's like you are saying, why did they ever create such a council of experts and why the heck did those experts join it, if they knew there is nothing you can do to predict it?

whether an earthquake is like or unlikely, claimed that the earthquake is unlikely and people should "relax"? For me, 50% is not much, so to say. I mean, with a 50% chance of trembles causing an earthquake we wouldn't need "top experts" to do that, right? Quote:

does it mean that people should take completely no responsibility for their decisions while dealing with seismology? @catfish Quote:
1. a/yes b/no c/i don't know 2. a/i don;t know Bcoz what you are saying, guys is like that the committee knew that they cannot predict the earthquake but still they said: hell no, relax and drink your wine, with a 150% certainty (as i said before we miss 100% of the trial's details, tho) |

50% is pretty much spot on, it either would happen, or it would not happen. You simply cannot be any more accurate than that. Seismologists have been predicting an earthquake that will devastate the San Francisco area for the last twenty to thirty years, they call it 'The Big One' on the San Andreas fault, but they can't tell you when it will happen, it could happen tomorrow, it could happen in a hundred years time. Like I said in my previous post, even the Japanese, who have the best earthquake monitoring system in the world can only give a minutes warning of an earthquake, maximum, often it's less. Quote:
http://www.nature.com/nature/journal.../392743a0.html http://books.google.co.uk/books?id=n...=0CB0Q6AEwADgU In 1976 Dr. Brian Brady, a physicist then at the U.S. Bureau of Mines, where he had studied how rocks fracture, "concluded a series of four articles on the theory of earthquakes with the deduction that strain building in the subduction zone [off-shore of Peru] might result in an earthquake of large magnitude within a period of seven to fourteen years from mid November 1974." In an internal memo written in June 1978 he narrowed the time window to "October to November, 1981", with a main shock in the range of 9.2±0.2. In a 1980 memo he was reported as specifying "mid-September 1980". This was discussed at a scientific seminar in San Juan, Argentina, in October 1980, where Brady's colleague, Dr. W. Spence, presented a paper. Brady and Spence then met with government officials from the U.S. and Peru on 29 October, and "forecast a series of large magnitude earthquakes in the second half of 1981." This prediction became widely known in Peru, following what the U.S. embassy described as "sensational first page headlines carried in most Lima dailies" on January 26, 1981. On 27 January 1981, after reviewing the Brady-Spence prediction, the U.S. National Earthquake Prediction Evaluation Council (NEPEC) announced it was "unconvinced of the scientific validity" of the prediction, and had been "shown nothing in the observed seismicity data, or in the theory insofar as presented, that lends substance to the predicted times, locations, and magnitudes of the earthquakes." It went on to say that while there was a probability of major earthquakes at the predicted times, that probability was low, and recommend that "the prediction not be given serious consideration." Unfazed, Brady subsequently revised his forecast, stating there would be at least three earthquakes on or about July 6, August 18 and September 24, 1981, leading one USGS official to complain: "If he is allowed to continue to play this game ... he will eventually get a hit and his theories will be considered valid by many." On June 28 (the date most widely taken as the date of the first predicted earthquake), it was reported that: "the population of Lima passed a quiet Sunday".The headline on one Peruvian newspaper: "NO PASO NADA" ("Nothing happens"). In July Brady formally withdrew his prediction on the grounds that prerequisite seismic activity had not occurred. Economic losses due to reduced tourism during this episode has been roughly estimated at one hundred million dollars (emphasis mine) http://www.telegraph.co.uk/news/worl...lse-alarm.html It is a case of the boy who cried wolf, I'm sure you've heard of that particular fable, if you take every single minor earthquake as being the foreshock of a major earthquake then eventually no-one will listen to you, which will cause problems if and when it does actually happen. After all, only five to ten percent of all small earthquakes turn out to be foreshocks of a major earthquake, so even a cluster of small earthquakes in an area is not a reliable fore-warning of a major event. Quote:
Honestly I don't know what kind of pressure they were under, I don't know how the Italian seismologist system interacts with the government. However it is likely that the seismologists are paid by the government, and thus if they issue a series of false alarms which cause financial problems for the government, and thus show themselves as unreliable, then they would likely have their funding cut. That is subjective though, as you said about the data from the trial itself, there's not enough data to be sure. Quote:
