However, much has happened since it went up, including the Blogger outage. Scroll down for a report on that.
There were approximately 1, deaths and this number is disputed to be higher in some reports. Nearly all the deaths resulted because a large segment of the population in the city of New Orleans did not evacuate Burton and Silver Why people stayed after being warned is the subject of many studies.
There are numerous influences that played a role in the decision not to evacuate for these people. Some of the more prevalent ones are inconsistent, confusing or incomplete risk messages, lack of trust in information sources, selective reporting by the media, and psychological and social factors that affect how information is processed.
The influences are all related to ineffective, poor risk communication in the planning stage as well as at the time of the event.
Katrina Evacuation Influences 2 Risk communication is a scientifically based discipline that deals with the dilemma between the risk that can kill people and the risk that alarms or causes outrage to them are often completely different.
Risk communication informs, persuades or warns people about health and environmental risks, and it analyzes problems and circulates findings on new knowledge Reluca Hurricane katrina evacuation risk communication influences Risk communications that were used to influence people to evacuate before and during Hurricane Katrina are textbook examples of what not to do.
It can also result in the decision to take no action at all. It is extremely important that all levels of government be consistent in their message of the risk and the level of hazard associated with the risk.
They should be provided complete information while presenting three separate scenarios for impacted and surrounding areas of impact. The scenarios should be framed in a least affected, moderately affected and worst case Katrina Evacuation Influences 3 scenarios providing actions to be taken by the people in each circumstance.
This empowers people to become responsible for their own decisions to some degree. Hurricanes are notoriously difficult in determining exact land fall location, intensity at land fall and the magnitude of destruction that will ensue.
Hurricane Katrina was no exception.
Information can change momentarily and much of it is open to interpretation and opinion. Meteorologists are often reluctant to make these types of forecasts for fear of looking foolish if the forecast does not pan out. As Katrina progressed toward the coast, the National Weather Service issued literally hundreds of warnings and other information.
There were so many, it was often difficult to keep up with all of them. Prior to Hurricane Katrina the basic message of whether or not people should evacuate the area was confusing, the city and state government were at odds with each other in the decision making process putting out very inconsistent messages.
Louisiana Governor, Kathleen Blanco, and the Mayor of New Orleans were at odds on the need to call for a mandatory evacuation of the city. The message is clearly not consistent. The two levels of government are in conflict within. The citizens are now Katrina Evacuation Influences 4 very confused and begin to distrust the information that is being broadcast.
Is there a mandatory evacuation or not becomes the question. The people in the lower Ninth Ward, who were so severely affected by the storm, believed that they had to look out for themselves and could survive the storm as they had done for many years.
Federal, state and local government conflicts in risk communications allowed rumors to prevail because of erroneous and misunderstood information. Clearly this is not effective risk communication. The lack of trust in the sources of information is a critical obstacle in effective risk communication.
Response efforts were greatly hindered in both pre and post event situations because of the lack of continuity in information and cooperation among all levels of government. A study conducted by UCLA researchers uncovered a deep level of distrust in a large majority of hurricane victims towards public health officials.
The statements of distrust were not solicited Katrina Evacuation Influences 5 they were all spontaneous statements, said lead researcher Dr. As we prepare for future disasters, I believe we have to account for this distrust in the shaping of the public health message.
These were evacuees who had been living shelters in Houston. Researchers surveyed the residents about their evacuation experiences, including how they had been evacuated and who had helped them.
They were surprised as to the unsolicited information that the evacuees offered. Because our semi-qualitative interviews did not include specific queries about trust and distrust, we were struck by the frequency, breadth and depth of distrust reflected in the spontaneous statements of the evacuees we interviewed, the researchers wrote.
This distrust may be rooted in the experiences of the Great Mississippi Flood ofwhen authorities performed controlled breaks along the levee to selectively flood poor areas in order to preserve the downtown financial district.After being taken down twice by Blogger within a single week, we got the message: It’s Time To Go.
Gates of Vienna has moved to a new address. Katrina Evacuation Influences 2 Risk communication is a scientifically based discipline that deals with the dilemma between the risk that can kill people and the risk that alarms or causes outrage to them are often completely different.
