Strong Ground Motion data from Nepal’s mainshock and two larger aftershocks
The Center for Engineering Strong Motion Data (CESMD) has made available strong motion records from the station NQ.KATNP (www.strongmotioncenter.org). The following links lead to strong ground motion data from Nepal’s mainshock and two larger aftershocks. (1) Magnitude 7.8 Gorkha earthquake (mainshock) on April 25th, 2015 (2) Magnitude 7.3 Aftershock on May 12th, 2015 at 07:05 (approximately 75 […]

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 […]

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.

Seismic Parameters of the Earthquake
The earthquake occurred at 7 km from Finale Emilia, 36 km from Bologna, 69 from Parma and 173 from Milan. Figure 1 shows the position of the epicentre according to INGV and the European-Mediterranean Seismological Centre (EMSC). Figure 1.
