Reconnaissance reports on structures damaged or collapsed by severe earthquakes have revealed several common characteristics in their structural members and systems, such as insufficient reinforcement details in beam-column joints and transverse confinements, low aspect ratios, soft and or weak stories, and eccentric plans.
It is found from earthquake reconnaissance that reinforced concrete (RC) shell structures, such as nuclear containments, cooling towers, roof domes, shear walls, etc., are the key elements in resisting earthquake disturbances.
RS techniques are emerging as useful reconnaissance tools for mapping geology, detecting anomalous structure, surface temperature anomalies and identifying geothermal indicators including hydrothermal alteration of minerals (clays, sulfates), sinter and tuff in prospective geothermal areas (Calvin et al. 2005).
He instigates the group's seasonal fix: a real estate reconnaissance throughout Milan to uncover its lost structures.
Putzig, N. E. et al. Subsurface structure of Planum Boreum from Mars Reconnaissance Orbiter Shallow Radar soundings.
Although the storm weakened further, reconnaissance aircraft observations on August 29 concluded that the structure of Danielle had improved compared to the previous day.
The SASR is primarily structured to conduct covert long-range reconnaissance and surveillance in small teams in enemy controlled territory, while commando units are utilised to conduct raids in larger groups.
Continued reconnaissance missions into the storm revealed a well-developed structure, indicating that the system had become increasingly powerful.
Operationally, Karen was classified as a strong tropical storm, but was reclassified as a Category 1 hurricane based on data from the reconnaissance flight late on September 26 and the less organized structure of the storm at that time.
The structure was photographed again in 2007 by the Mars Reconnaissance Orbiter, further dashing our hopes and dreams for an ancient Martian monument as the rocky ridges and eroded slopes came into ever clearer resolution.
In other cases there are no surface traces, and the outline of suspected structures is revealed only by aerial or geophysical reconnaissance.
