At landfall, Micheal produced design-level wind speeds in some areas and generated 14 ft  storm surge that devastated many structures along the beaches as well as extending miles inland.  in communities like Mexico Beach, it is an important validation of code and construction practices in the Gulf Coast.

This StEER report presents an overview of meteorological features of Hurricane Michael, the regulatory context and pre-event response, the impacts of this storm event, and current conditions by collocating publically-reported information. The report places particular emphasis on Florida, but also summarizes impacts to other affected states.

This Preliminary Virtual Assessment Team (P-VAT) Report represents the first product of StEER’s larger coordinated response to this event, informing and supporting other research teams seeking to learn from this disaster.

Haiti M5.9 Earthquake 2018: Preliminary Report by StEER

StEER is pleased to release its PVAT report on the 2018 Haiti Earthquake:
Download link:  http://bit.ly/StEER-V2


On October 6, 2018, at 8:12 pm local time, a magnitude 5.9 earthquake, with a depth of
11.7 km, struck 19 km northwest of Port-de-Paix, Haiti. The earthquake damaged structures, killed at least 17 people, and injured 333 people at the time this report was authored. Shaking was felt as far away as Port-au-Prince, 219 km away from the epicenter. There were several aftershocks following the earthquake, including one with magnitude of 5.2.

The earthquake caused part of a hospital to collapse in Gros-Morne, damaged the façade of the Paroisse Saint Michel Archange de Plaisance church in Plaisance, caused a cultural center to collapse in Gros-Morne, damaged a holding cell at the Police Nationale d’Haiti Commissariat de Port-de-Paix in Port-de-Paix (allowing several detainees to escape), caused an auditorium to collapse in Gros-Morne, damaged several classrooms at San Gabriel National School in Gros-Morne, and destroyed houses in the communes of Chansolme, Gros-Morne, Plaisance, and Port-de-Paix as well as on the island of Tortuga. Until now, there are no reported cases of bridge damage or geotechnical failures.

Overall: 7,783 families are in urgent need of assistance, due to the partial or total collapse of their house. Damage is mainly concentrated at Port-de-Paix (Nord-Ouest) and Gros-Morne (Artibonite) with 353 collapsed houses and 7430 severely to lightly damaged houses, including some cracks. Some health and education infrastructure have been damaged. In the department of Artibonite, 42 institutional buildings (schools, churches and other) are either severely or lightly damaged at Gros Morne. Four national and private schools collapsed at Pilate in the Nord department.

The report is being curated in DesignSafe (DOI available shortly): https://www.designsafe-ci.org/

The report is intended for use by those planning potential follow up damage investigations and we hope it will also provide value to the affected communities affected in assessing the damage and current state of infrastructure, as they begin the repair and build process.

Hurricane Florence (14 Sept 2018) Flood and Wind Damage to the Carolinas

Hurricane Florence made landfall on 14 September 2018 and it caused inland flooding of historic proportions that produced major disruption through large regions of North and South Carolina.  The hurricane cut access to Wilmington, NC, a city of 120,000 when bridges failed, and all roads leading to it were flooded. As thousands of residents wait for flood waters to recede before they can return to their homes and begin cleanup and repairs, natural hazards researchers are combing through damaged areas to collect and preserve damage information for future research. While thousands of North Carolina residents are living through the shock of this disaster  hundreds of peer-reviewed papers exist extolling the inevitability of such flooding and proposing solutions to mitigate damage.

This damage assessment report, the 20th produced by the University of Florida’s Wind Hazard Damage Assessment Group summarizes the damage observations using publicly available information from the National Weather Service , national and local news sources. and social media. For the first time, WHDAG students collaborated with the recently formed StEER: Structural Engineering Extreme Event Reconnaissance Network, sponsored by the National Science Foundation.

Johns Island Tornado (25 September 2015)

In the early morning hours of Friday, the 25th of September, a tornado quickly formed within a convective band moving ashore from off the coast of South Carolina. The tornado touched down on Johns Island, in Charleston County, SC, around 12:38 AM and remained on the ground for almost 7 miles, leaving a path of damaged homes and downed trees that was up to 0.5 miles wide. Thankfully there were no fatalities or even major injuries, despite it being a nighttime tornado, which typically leave residents little time to prepare and seek shelter. The National Weather Service rated it an EF2 on the Enhanced Fujita Scale with an estimated maximum wind speed of 130 mph.

The University of Florida Wind Hazard Damage Assessment Group report linked below summarizes the damage using publicly available information from social median and local news sources. Our report focuses on the fact that despite the relatively long and wide path, only one home suffered major damage that will likely require it to be rebuilt. We hypothesize that this can at least partially be attributed to the wind resistant building codes that have been in use in Charleston County for the past couple decades. Implications of this with respect to the EF Scale, the damage-based scale use to rate tornado intensity, are also discussed.

Tornadoes in a Bottle

On Thursday last week, Wind Hazard Damage Assessment Group (WHDAG) members, Austin Thompson and Malcolm Ammons received the opportunity to teach students at Williams Elementary School about forensic engineering and tornadoes. This afterschool program began in partnership with the Gainesville Community Science Coalition in order to foster an appreciation for the sciences in students at a young age.

The group of 12 4th – 5th graders learned about tornado formation and safety. Additionally, Austin and Malcolm used a 1/8th scale house model to show the students how homes behave in a tornado when various components fail. Afterwards, the kids took part in an EF Scale training activity using damage photos from Moore, OK 2013 tornado. At the end of the meeting, the students made tornadoes in a bottle, using empty soda bottles, Teflon tape, and water.

For fun games and other ways to educate kids on tornadoes, check out the Florida Division of Emergency Management’s KidsGetaPlan.com.
