A new webGIS app: The seismic risk of Bucharest

Some of our recently published work (Toma-Danila et al., 2022) regarding the Network-risk methodology and toolbox applied to Bucharest has been included in a new app: “The seismic risk of Bucharest”.

Check it out at https://tinyurl.com/yt32aeyxAlthough in Romanian, it shouldn’t be hard to understand.

The app includes layers regarding:

  • individual buildings in seismic risk class I and II or urgency categories (all highly vulnerable buildings – but not all of them in reality)
  • buildings affected by the 1977, March 4 (Mw 7.7; 94 km depth) and the 1940, November 10 (Mw 7.7; 150 km depth) Vrancea earthquakes
  • areas which might become inaccesible in case of an earthquake (based on Toma-Danila et al., 2022)
  • service area results for the nearest hospital and fire department (based on Toma-Danila et al., 2022)
  • routes toward important hospitals, for 4 representative analysis points in the city centre (based on Toma-Danila et al., 2022)
  • results of the hazard and risk analysis (for the 1:1000 years return period) performed by INCDFP, URBAN-INCERC and UTCB within the Ro-Risk Project in 2017
  • hospitals in Bucharest and Ilfov County, with info regarding their importance in case on an earthquake (based on Toma-Danila et al., 2022)
  • fire stations in Bucharest and Ilfov County (based on Toma-Danila et al., 2022)
  • seismic zonation maps, according to the present seismic design code (P100-1/2013)

Pre-Quake and Network-risk

The recently published article of Toma-Danila et al. (2022), to which Pre-Quake contributed, reveals the implication of earthquakes on emergency intervention travel times in Bucharest, showing:

  • which areas could become unaccessible due to building collapse;
  • which are the implications of typical and post-earthquake traffic on travel times;
  • which are the safe access routes and important hospitals in case of an earthquake.

As expected, the city center might become severely hard to reach in case of earthquake. The use of delimited tramway lines for ambulances has an important impact in reducing travel times, but not all areas benefit from these. Furthermore, an emergency hospital located in south-western Bucharest might be highly important in reducing travel times for the area. The articles provide enough solutions for better emergency reduction planning.

2021 – New project presentations

What were we up to in the last period? Innovative articles and presentations, following the project objectives. We participated (online) at the 37th General Assembly of the European Seismological Commission, at the Balkan Geophysical Society International Congress and at the 1st Croatian Conference on Earthquake Engineering, presenting:

Peer-reviewed research articles in highly visible journals will soon follow.

Also, on 10 November 2021, at 81 years after the major 1940 Vrancea earthquake, we launched on YouTube a video devoted to this important event, exploiting the information gathered within Pre-Quake and telling its lessons. Here it is:

Lessons from the past

In order to keep the lessons of previous earthquakes and their implications alive, we’ve added two new sections to our website:
