April 6, 2009 M6.3 Very seismic region L'Aquila built on ancient

lake bed – amplifies motion

Medieval city –old construction not to modern codes

20,000 buildings damaged

30,000 homeless

Basic EQ Facts +1 magnitude = +30 x energy (a few small

ones don’t stop a big one) Most deaths in earthquakes occur in

collapsed buildings

Earthquake Prediction A reliable earthquake prediction

should occur BEFORE the event and include:LocationTimeSizeHow likely

Reasons behind prediction (justification)

Short-term EQ Prediction – Hasn’t been done reliablyNone of these are reliable Radon gas measurements Animal behavior (dogs barking) Alignment of the moon and the sun Micro earthquakes Earthquake swarms Changes in shear and primary wave

velocities (Vs/Vp)

False Prediction by Giampaolo Giuliani – March 29, 2009 Phoned the mayor of the town of Sulmona,

about 55 kilometers southeast of L'Aquila, to expect a "damaging" — or even "catastrophic" — earthquake within 6 to 24 hours.

Loudspeaker vans warned the inhabitants of Sulmona (not L'Aquila) to evacuate

Residents panicked. Then no EQ occurred Giuliano cited for inciting public alarm and

prohibited from making public predictions.

Quote from Enzo Boschi

“It is unlikely that an earthquake like the one in 1703 could occur in the short term, but the possibility cannot be totally excluded.”

Note: No mention was made of what to do if a major earthquake should occur

Quote from Marcell Melandri – Lawyer for Enzo Boschi . . . scientists may now, effectively, be

forced to rethink how they interpret science when citizens are worried. And that, he says, will compromise their authority. “In Italy you will now see many more false alarms in such situations, because experts will choose to cry wolf when in doubt. In the end they will become less and less credible.”

You Are the Court Judge Were the scientists/engineers negligent or just

guilty of poor communication of the risk by providing “incomplete, imprecise, and contradictory information”?

Is poor communication a crime punishable by prison?

In the future should the committee predict an earthquake even if the probability is very small?

Should issuing a false alarm also be a crime? List the important facts you know and those you

would like to know more about List the conflicts Do any code of ethics elements apply here?
