When things go wrong . . . Part 3


This is the final post in the "When things go wrong series . . ." Click to see Part 1 and Part 2

Italian Scientists Found Guilty

WHAT: On April 6th, 2009, there was a 6.3 magnitude earthquake in L’Aquila, Italy. The region has a long history of earthquakes and the citizens of L’Aquila usually sleep outside during times when there are small tremors. However, for this earthquake people stayed inside and 309 people died. The community had heard reports from the nation’s scientists that it was unlikely a large earthquake would occur. Six Italian scientists and one ex-governmental official were put on trial and recently found guilty of manslaughter. All of them were from the National Commission for the Forecast and Prevention of Major Risks.

WHERE: L’Aquila, Italy, a town located in a fault rich area of Italy.

The location of the 6.3 earthquake that hit Italy in 2009.

Damage of homes in L'Aquila, Italy.
HOW: There were tremors occurring in L’Aquila and the citizens were becoming concerned that a large earthquake could be coming. The National Commission for the Forecast and Prevention of Major Risks calmed the citizens down by stating that it was unlikely that a large earthquake could strike. Because of the advice of the Commission many residents stayed in the area and in their homes.

WHY: This is an important case because it is putting the communication of science on trial. There is no way to accurately predict a major earthquake but the geophysicists failed to communicate that effectively to the people of L’Aquila. The people believed that there was no risk because the scientists said an earthquake was unlikely. The scientists knew that there was still a chance that a large earthquake could occur but wanted to calm the citizens.

WHO: This story is very sad and unfortunate. I think many people, especially the survivors in L’Aquila, are trying to find the people they should blame. Who should be held responsible for the deaths? The court has ruled that the scientists did hold some of that responsibility (although the decision is being appealed). For me, it seems clear that the seven people from the National Commission for the Forecast and Prevention of Major Risks failed at their job. The main failure is the lack of risk communication. None of the citizens of L’Aquila should ever have heard a message of stay inside. This story shows how critical it is that scientists be able to communicate with the public without just dumbing down the science.

Do you think the scientists are guilty? Who is to blame? What should the Italian government do to avoid another tragedy like the L’Aquila earthquake?

This concludes the "When things go wrong . . ." series. Let me know if you would be interested in hearing about a particular subject in geophysics. Thanks for reading!

When things go wrong . . . Part 1


 Geophysics is exciting, interesting, and useful – most of the time. Geophysicists (me included) focus on how to make images sharper, seismic records clearer, and inversions run better. We forget how our field interacts with society – especially when something goes wrong.

Now geophysics usually is not a cause of controversy. But because geophysics is involved in the industries where disasters occur, we are grouped with those industries when the finger pointing starts. And I don’t think that’s a bad thing. We should be held accountable for the work we do and understand how that work helps make decisions.

I am going to do a mini-series on three different controversies that involve geophysics in one way or another. Today I’m going to talk about the BP Macondo well disaster. Tomorrow we’ll explore what happened in Pavillion, WY. And Friday we’ll investigate why six Italian scientists might be headed to jail. These all raise important questions for both scientists and society to answer.

BP Deepwater Horizon disaster

WHAT: It was April 20th, 2010, when an explosion occurred on the BP Deepwater Horizon oil rig. The rig caught fire and sank two days later. Eleven men died. The explosion and fire where caused by hydrocarbons (oil) coming up out of the well onto the rig. The well was severed and spilled oil into the Gulf for 87 days.

WHERE: Out in the Gulf of Mexico.

HOW: The committee that investigated the disaster concluded that the main failure was in the cement barrier that let the hydrocarbons flow upward and onto the rig.  The committee states:
The loss of life at the Macondo site on April 20, 2010, and the subsequent pollution of the Gulf of Mexico through the summer of 2010 were the result of poor risk management, last minute changes to plans, failure to observe and respond to critical indicators, inadequate well control response, and insufficient emergency bridge response training by companies and individuals responsible for drilling at the Macondo well and for the operation of the Deepwater Horizon.
Go HERE for the full report.

WHY: The lesson to learn from the BP Deepwater Horizon disaster is that for as much as we think we know about the processes involved in drilling for oil there are still unknowns and we are all human. The crew on the rig that night were about to head home after two weeks working on a tough well. When a well pressure test didn't make sense the engineers decided it was a rare phenomenon and didn't raise alarms. We take great risks to get to oil that is deep under water and earth.

WHO: We take great risks in many things that we do but with the large impact the BP oil disaster had on the coastal communities, it makes me wonder who said its OK for the oil companies to take those risks? The government? Geophysicists are usually upfront about the limits of their methods but this disaster makes defining the extent of our knowledge important.

What do you guys think about the disaster? What do think is the one take away for scientists? For society?
