The EF5 tornado that devastated Joplin, Missouri on May 22nd of 2011 also passed through Earthscope's USArray Transportable Array (TA) network. Stations within the TA network are configured to observe seismic and surface pressure phenomena at 1 and 40 samples per second in real-time with a suite of instrumentation including infrasound and environmental sensors inside the vault installations. The Joplin event passed approximately 2 km south of station T38A, whose location near the town of Joplin allowed for the observation of the storm in a unique and compelling way. The data presented here will further depict the intensity of the EF5 storm. Possible implications of the TA network for aiding the determination of tornado severity and perhaps providing additional early-warning detection will be presented by comparing data of surrounding stations.
