Hurricane #1 for the Season

Two days ago there was an 80 percent chance of the storm system on the central or northern Atlantic coast of Florida developing into a tropical storm and on morning of July 2 the system did just that.
“Hurricane Arthur has strengthened some more this morning. Maximum sustained winds are now 90 mph, a strong Category 1 hurricane on the Saffir-Simpson Hurricane Wind Scale.”

Three Year Anniversary of May 22, 2011 Joplin Tornado

It’s been 3 years since the May 22, 2011 EF-5 tornado left a 7-mile long gash in the city of Joplin, over 5000 buildings destroyed, and 158 people dead. Two years after the storm, the Structural Engineering Institute of ASCE published the Joplin, Missouri, Tornado of May 22, 2011: Structural Damage Survey and Case for Tornado-Resilient Building Codes.

This 50 page report followed a joint engineering reconnaissance trip to Joplin, Mo May 29, 2011. The primary objectives were to better understand the predominant structural failure mechanisms associated with tornadic loads and suggest improvements to influence future building practices.
Similar damage assessments have helped to inspire local governments to adopt new building codes, as was the case with Moore, Oklahoma. Just last month, the Moore City Council adopted new codes that would institute higher wind load standards for buildings.

A Symbol of Resilience

The former Mercy Hospital Joplin in the Southwest part of the city, stood as a iconic testimony to the intensity of one the most deadly tornadoes in U.S. history. The hospital, demolished at the beginning of 2012, is now in the reconstruction processes scheduled to be completed March 2015, to continue to serve its some 700,000 patients.

44th Anniversary of 1970 Lubbock Tornado

This week we remember the massive tornado that tore through Lubbock, Texas on May 11th 1970, leaving 26 dead, $1.48 billion (in 2013 dollars) in damages, and dozens of homes and businesses destroyed.

This event behaved as a sad, but necessary, catalyst for the F-scale (see EF-scale), a tornado rating system based on post-tornado event damage assessments, produced by Dr. Ted Fujita. It also helped to justify the development of the Wind Science and Engineering (WISE) Research Center at Texas Tech University.

Glaring Weak Links

John Lewis is a meteorologist stationed at the Little Rock, Arkansas National Weather Service office. In his article, “No EF5 This Time: Anchor Bolts Not Detected in Most Construction,” posted May 3rd, Lewis points to a major engineering advancement in the rating of tornadoes since the reformulation of the Fujita scale into the Enhance Fujita scale, the use of engineering principles concerning load paths.
