Summaries of Specific Buildings

The building-specific files below contain as much information members could publicly find to support any reconnaissance teams prior to their departure. Weiguan Building, Version 1.0, compiled by Antonio Zaldivar, Alvaro Canga, Pratik Deogekar, and Gengrui Wei, University of Illinois Urbana Champaign, dated 2016/02/15 Kings Town Bank, Version 1.0, compiled by Gengrui Wei, University of Illinois […]

Seismic Response of Public Buildings and Infrastructural Systems

In the Emilia Romagna Region, nine public buildings are monitored by the OSS (hospitals, infrastructures, schools), concentrated in the east and the Appennine, which is more active from a seismic point of view. Following the May 20, 2012 Emilia earthquake, two monitoring mobile systems have been installed on the Prefectures of Ferrara and Modena. Detailed information on […]

Short update on the earthquake sequence

  Table 1. List of main events of the earthquake sequence from the 29th of May to the 6th of June 2012.                                                        Date Hour (UTC) Latitude Longitude Ml […]

Some notes about seismotectonics

  Figure 1. Comparison of focal mechanisms reported by other institutions (http://www.emsc-csem.org/Images/EVID/27/270/270116/270116.MT.jpg).     Figure 2 shows the cluster of aftershocks for the two events, the 20th and 29th of May 2012. A migration of seismicity towards west is clearly visible. The relative location of the two earthquakes and the distribution of Coulomb stress, suggest that the June […]

Shakemap Emilia-Romagna-Modena Earthquake May 29th 2012

 This map was produced automatically using the data recorded by the seismic stations near the epicenter – (red triangles in Figure 1 – see also the archive for more maps http://shakemap.rm.ingv.it/shake/archive/2012.html ).   Figure 1. Shakemap (PGA) describing the shaking pattern produced by the May 29th event.  

Seismological characteristics

The detailed information using in the regression can be seeing in the INGV website at the following link: http://ismd.mi.ingv.it/evento_35.php?var1=772691&path=120520020352 (link updated in 2018)   Figure 1. Epicenter (red star) and focal mechanism proposed by the INGV. The stations used to obating the mechanism are shown as red triangles.      Figure 2 shows the main event […]

Accelerograms and ShakeMaps

A preliminary report of the accelerograms and the response spectra of the RAIS stations can be downloaded here (last accessed 25/05/12), whilst the accelograms and response spectra of the stations of the network RAN can be downloaded from here (last accessed 25/05/12).     Figure 1. Map of recorded PGA of some stations of the RAN network (last accessed 25/05/2012) and the RAIS […]
