چکیده
At 18:08 on August 4, 2020, a large explosion occurred at Hangar 12 in the Port of Beirut. The size was equivalent to that an earthquake with local magnitude (ML) 3.3 according USGS. As one largest nonmilitary explosions ever impact urban region, this event provides unprecedented opportunities document impacts infrastructure. To facilitate data collection, Geotechnical Extreme Events Reconnaissance (GEER) Association coordinated multiagency response directed toward collection perishable engineering interest. Two main categories infrastructure systems were impacted: Beirut and building stock. Within Port, triggered quay wall failure flow slide, strongly impacted grain silo structures close proximity 12. city, historical masonry structures, older reinforced concrete modern high-rise impacted. Through combination in-person inspections street-view surveys, we collected structural performance (including damage load-bearing elements) façades. Performance levels classified procedures applied following earthquakes (for performance) newly proposed façades). We describe spatial distributions these types dependencies source distance location-to-explosion direction. demonstrate physical damages correlated proxy maps produced by Jet Propulsion Laboratory Earth Observatory Singapore based Copernicus Sentinel-1 satellite synthetic aperture radar data, stronger correlation than façade damage.

Explosion effects on buildings
Nowadays there are many software tools available which, in case of a gas release, allow to calculate the dispersion of the gases (and hence predict the size and shape of the cloud) and to calculate the overpressures as a function of distance if this gas cloud should explode. The next step is then to predict what the consequences of these overpressures will be: to what extent will buildings (and...

We present a discussion on the effect of nearby buildings on the electric and magnetic fields radiated by lightning. Electric and magnetic fields radiated from distant natural lightning have been measured simultaneously on the roof of a building (the Power Systems Laboratory of the Swiss Federal Institute of Technology, Lausanne, Switzerland) and on the ground at different distances away from i...
