Rescue and Storm Surge Video from Hurricane Isaac – Social Media Resources, Part 5

Wednesday, August 29th, 2012

Author: Disaster Social Network, IEM

Isaac has been downgraded to a tropical storm but is still dropping heavy rains on the Gulf states and cause many to lose power. Homes were flooded this morning in Plaquemines Parish as the water topped the 12-foot levee.  Below are links to video and photos of the storm surge and rescues that occurred today.

Hurricane Isaac made landfall during the overnight hours.  At 9am CDT this morning, Isaac showed some weakening, but is still a Category 1 hurricane. It is moving slowly at 6mph and is center about 40 miles southwest of New Orleans. It is the threat of dangerous storm surges and flooding that has officials most concerned. There has been a very close watch on the levees as water topped the 12-foot levee in Plaquemines Parish this morning.

This morning IEM’s Disaster Social Network has tracked and collected some of the best eye-witness tweets, maps and video. Some of the Twitter accounts we have reposted from yesterday since we feel they are providing the most credible information and eye-witness reports.

Hurricane Isaac is expected to make landfall as a category 1 hurricane in a few short hours this evening on the Gulf Coast.  IEM’s Disaster Social Network has been collecting site and social media accounts to watch as the storms hits during the overnight hours. Please note the webcams that have been set up to provide live views of the storm.

Economic Losses from Hurricane Isaac Could Reach $21 Billion

Tuesday, August 28th, 2012

Author: Dr. Lloyd Blanchard, Director of Public Performance Management, IEM

Hurricane Isaac is currently predicted to make landfall near New Orleans on or just before the 7-year anniversary of Hurricane Katrina. However, global security consulting firm IEM estimates the results will be far different.

Katrina was a Category 3 storm that caused $108 billion in damages (the costliest ever in terms of dollars) and about 1,200 deaths (the most from a hurricane in 84 years). A day before projected landfall, Isaac has just reached hurricane strength with winds at 75 miles per hour, and is expected to make landfall as a Category 1 or 2 storm. According to IEM economist Dr. Lloyd Blanchard, “Based on this current information about the storm, IEM estimates that Isaac will cause less than 30 deaths and result in damage costs ranging from $18 to 21 billion.”

While the most obvious difference between these two storms lies in their severity (as measured by the Saffir-Simpson scale), the difference in wind speeds does not explain the difference in likely outcomes. (more…)

As Hurricane Isaac approaches the Gulf Coast today, the track Isaac is taking is eerily similar to the track Katrina took seven years ago at this same time. Although Isaac is not nearly as strong or expected to cause the extent of damage that Katrina did, many Gulf Coast cities are ordering evacuations. I wanted to see just how close the tracks of the two storms are, so I overlayed Isaac’s track with the historical track Katrina took in 2005. Isaac is expected to hit the Gulf Coast within hours of the seventh anniversary of Katrina.

This map depicts the forecasted track of Hurricane Isaac and the historical track that Hurricane Katrina took seven years ago almost to the exact date and time. They are approximately 12 hours apart. The lines indicate the center track of each tropical cyclone and where Isaac is forecast to be as it makes landfall. As you can see from the map, Isaac is expected to make landfall at almost the same spot Katrina did. (more…)

Tropical Storm Isaac is expected to become a Category 1 or 2 hurricane before reaching the northern Gulf Coast late Tuesday evening (August 28). As the storm drenches Florida and approaches the Louisiana, Mississippi, and Alabama coasts, IEM is monitoring social media accounts of the disaster for the most current and relevant information available.

Chemical Economic Benefits Have Inherent Chemical Transportation Risks

Friday, August 24th, 2012

Author:  David O. Willauer, IEM Transportation & Geospatial Technologies

This week’s Hazmat incident involving a crash between an isobutene tanker and another motor carrier is a reminder of risks involved with daily chemical transportation. Isobutylene (synonym for isobutene) when blended with gasoline is used to make high octane aviation gasoline blends. First responders and emergency managers should be commended for their efforts to close the interstate quickly to avoid providing this highly flammable chemical a chance to find a source to ignite. While the primary hazard is flammability, this chemical also presents toxicity risks.

Crashes involving large trucks carrying hazardous materials are relatively rare. Less than 10 percent of truck shipments include Hazmat as all or part of the cargo load. Less than 5 percent of large truck crashes involve trucks carrying Hazmat. While most motor carrier crashes are rare, fuel tanker crashes represent most of the incidents. A report to FMCSA found that Class 3 Hazmat (flammable liquids) accounted for 64 percent of hazmat crashes where cargo was released during the crash. (more…)

Evacuations and the Isobutene Event in Baton Rouge, Louisiana

During yesterday’s isobutene incident in Baton Rouge, officials issued an evacuation order for people in the immediate area. How did they decide how large an area to evacuate?

In most cases, emergency responders refer to the Emergency Response Guidebook, or ERG, which provides quick information about how to respond. For a small spill or leak of isobutene, the ERG recommends keeping people at least 100 yards away. For large spills, such as most of the contents of a tank truck, the distance increases to ½ mile. If a railcar or tank truck is involved in a fire, the risk increases substantially due to the possibility of a large explosion and people should be kept at least 1 mile away.

Having worked as an Atmospheric Scientist and Dispersion Modeler for over 30 years, my specialty is studying how toxic chemical clouds move through the air and developing computer models to predict the areas that may be at risk so that people can be protected. The evacuation distances in the ERG are determined by running computer models like those I develop while assuming the worst-case situation and seeing how far downwind the plume might be dangerous.

Isobutene Leak on I-10 in Baton Rouge, Louisiana

Wednesday, August 22nd, 2012

Author: Steve Stage, Atmospheric Physicist/Dispersion Modeler, IEM

Early this morning, a tanker truck full of the toxic chemical isobutene was damaged in an accident on Interstate 10 in Baton Rouge, Louisiana.

isobutene Hazmat PlacardYou may have noticed diamond-shaped signs, or placards, containing a number on the back of tanker trucks. These placards are required on all trucks carrying hazardous material in the U.S. The identification number on the placard makes it easy for emergency responders to quickly determine what chemical they are dealing with. For this morning’s accident, the placard read “1075,” indicating that the chemical is isobutene. Every chemical tanker truck is also required to carry Material Safety Data Sheets (MSDS) that describe the chemicals being transported. (more…)
