In engineering this is a 'post morten' whereby experts will look into how well a certain structure was built and give guidances on how to avoid the problem. Read please the document. and see how the wooden houses were left in this photo: noaanews.noaa.gov Need better civil engineers there I suppose. La Plata Tornado Damage Survey On April 30, 2002, Dr. Long Phan of the Structures Division, Building and Fire Research Laboratory of the National Institute of Standards and Technology (NIST), visited La Plata, MD, to survey the structural damage caused by the Sunday, April 28, 2002, La Plata tornado. The tornado had been preliminary rated as an F5 tornado (117 m/s to142 m/s (261 mph to 318 mph) wind speed) by the National Weather Service. The path of structural damage in La Plata begins approximately 1.2 km (¾ mile) west of the junction between MD routes 301 and 6, and ends at about 6.4 km (4 miles) east of this junction. The types of construction that were damaged include conventional wood frame construction (residential) and low rise, brick and masonry commercial structures (Archbishop Neale and La Plata United Methodist churches). For residential construction, a majority of the structures sustained loss of roof and part of the leeward walls, with a lesser number sustained total collapse. For commercial structures, the damage was limited to mainly loss of roof and partial collapse of leeward walls. During the damage survey, forensic information that might provide insights into how well the damaged structures were built, such as the wall-to-roof and wall-to-foundation connections, were collected for future analysis.
