Short Answer
NO, none of the data nor the "analysis" can predict effectively the earthquakes, because that impossible with our current detection capabilities and understanding of the earthquakes.
Long Answer
First, what is a "Scientific earthquake predictions"?
Scientific earthquake predictions should state where, when, how big,
and how probable the predicted event is, and why the prediction is
made.
R. Ludwin Reference on The Pacific Northwest Seismic Network
Let`s review each part:
where:
We already know where the earthquake occurs, based on list of prior earthquakes and the Plate tectonics, but we can`t pinpoint the place of the next one.
when and how big:
in the same way you can check the statistic world wide here and speculate about time intervals and such, but will be gambler fallacy state a date for a earthquake with 100% certainty.
how probable:
That depends of the method of predictions, as I state before, there is none.
why:
even when we know why an earthquake occurs, put this knowledge to use in predictions is sparse to say at least, there isn`t a practical way to probe vast regions of the earth with stress sensors at such depths.
Despise all of this a statistic/"finite element" model, based on a well know area like California and with extensive computational power can forecast earthquakes, but with "not-so-impresive" results (not useful for prevent deaths or evacuate people), best forecasts are about 10 times more accurate than a random prediction (seen here, here and here), still yielding results like this:
While all the forecasts showed some success in forecasting the
locations of likely earthquakes, the NASA-funded UC Davis forecast
team, which included Andrea Donnellan of NASA's Jet Propulsion
Laboratory, Pasadena, Calif., was found to be the most accurate at
picking the quake locations. It correctly labeled 17 of the 22
affected grids, and gave the highest probability of an earthquake in
eight of these 17.

The scientific community have studied many variables to find some form to predict earthquakes, from very long ago, like in radon analysis (emphasis mine):
Scientists studied radon as a possible earthquake warning signal as
far back as the 1970s, and while they found convincing cases of radon
releases before some earthquakes — for example, levels of radon in
groundwater were 10 times normal before the earthquake that hit Kobe,
Japan, in 1995 — the correlations were not strong enough or clear
enough for useful predictions.
NY times
in the same way a precursor, "earthquake swarm" or "foreshock earthquakes"(Wikipedia definition), are a big series of minor but very frequent minor earthquake, can be a energy release or a big earthquake precursor:
The worry is that one of these small earthquakes could cascade into a
big earthquake like the one that badly damaged Basel in 1356.
Conversely, the small earthquakes could instead be relieving stress
along a fault, reducing the likelihood of a larger quake.
NY times
another reference about this:
However, most earthquakes lack obvious foreshock patterns and this
method has not proved useful, as most small earthquakes are not
foreshocks, leading to probable false alarms.

And we can go on and on and on about so many methods like:
- Strain-rate changes.
- Seismic velocity changes.
- Electrical conductivity changes.
- Hydrological changes.
- Electromagnetic signals.
- Thermal anomalies.
- Anomalous animal behavior.
- Seismicity patterns.
- Proxies for accelerating strain.
but in the end, nothing past beyond anecdotal:
The search for diagnostic precursors has thus far been unsuccessful.
This silver-bullet strategy for earthquake prediction is predicated on
two hypotheses: (1) large earthquakes are the culmination of
progressive deformation sequences with diagnostic precursory changes
in the regional stress and strain fields, and (2) diagnostic
information about an impending earthquake can be extracted from
observations that are sensitive to these precursory stress and strain
changes. Neither of these hypotheses has been empirically validated.

More info about earthquake prediction can be found in the wikipedia, even when is a wikipedia article this is very well referenced.
Conclusion
Actually, there no way to predict or forecast earthquake in a meaningful way to prevent loss of life or mitigate his effects without incurring a BIG financial loss by false positives or loss of credibility in authorities or scientists.
About the imprisonment
all the seven people, 6 scientists and a civil servant were, judged and convicted as a a whole, without regard for who said what:
"The prosecution have not distinguished between the different
defendants' actions or words. To be prosecuted for other people's
miscommunication of your scientific advice is a travesty."
The Huffington Post
but above all for a terrible and gross miscommunication, never amended by those scientist:
Employed by Italy's Major Hazards Committee to assess earthquake risks
and communicate them to the government and the public, the
seismologists got the science right, but left the job of public
communication to a civil protection official with no specialist
knowledge of seismology. His statement to the press was, to put it
mildly, a grossly inaccurate reflection of the situation: "The
scientific community tells us there is no danger, because there is an
ongoing discharge of energy. The situation looks favorable." At this
point, the seismologists should have stepped in. But they did not, and
the message stuck.
New Scientist
Well maybe being absent during this statement help to overlook this terrible misinterpretation for many of them:
Immediately after that meeting, De Bernardinis and Barberi, acting
president of the committee, held a press conference in L'Aquila, where
De Bernardinis told reporters that "the scientific community tells us
there is no danger, because there is an ongoing discharge of energy.
The situation looks favorable". No other members of the committee were
at the press conference.
Nature
Afterthoughts
Another angles not seen:
- Why the Italians, living in a seismic country, keep un-reinforced building inhabited? the tourism is worth the risk?The centuries old list of earthquakes
- Why the Italians, living in a seismic country and in no seismic-resistant building, believe the authorities about "you can sleep quietly, no earthquake" statement? is to blame the lack of culture?
- Why blame the seismic expert instead the builder?
- Why the Italian seismic expert never refute the "there no danger" statement?.
My last thought
- would be terrible that we need to extend the CYA (Covert Your Ass) policy outside of USA.
- Can we blame the weather-cast announcer/scientists for the car accident occurred by his "inexact, incomplete and contradictory information".
- I have to proof-read more this answer.
