Government and Crisis Managers Experts 



The Rosenzweig Disaster Magnitude Scale R.D.M.S.©, or Universal Disaster Magnitude Scale is based on the only measurable parameter in any crisis or disaster scenario, regardless its nature:


“Interaction Patterns”


Through interaction patterns alteration measurement, it can be easily understood what does people stop doing, the importance of what they stopped doing and the causes. 


The R.D.M.S.©  is an important tool for crisis sense making, because is related with the sources of problems, in real time, allowing a correct prioritization of reaction plans, as well as solution´s effectiveness tracking through which recovery forecast can be calculated. 


Regardless the online system tools, apps, or other tech platforms that can be attached to the Scale, the R.D.M.S.© by itself is a novel concept for sense making in real time.


To facilitate the easy understanding of the scale, we have splited the video in 7 parts, allowing users to jump between the different aspects of the presentation. How ever, we strongly recommend to keep the sequence in order to follow the basic ideas.


As this is a technical document for experts, an academical approach is suggested.

Video 7of 7: R.D.M.S. online software

We have placed the R.D.M.S. online software for those of you who want to see right away the Scale practical application before understanding it.

You can start watching for 3 minutes and then jump to minute 6.53", as well as minute 10.12" to whatch the scale fully working. Then we suggest to go over the rest of the videos and come back.

The R.D.M.S. online software offers all the information needed in real time, and place it in a tablet, or in the whole screens of a crisis room. 

Video 1of 7: Introduction

Sense Making through numerical indicators that displaces subjective information with object measurable data, in the field, in real time, regardless the type of phenomena and the unique combination of factors.

Video 2 of 7: How does it works?

How can the alteration in interaction patterns can me measured if every social and natural phenomena scenario is unique?


How can priorities can be understood depending on the environment, cultural believes?

Video 3 of 7: Wide range of applications

How can priorities can be established along the cultural kaleidoscope around the world?. How can a single numerical indicator be used for several purposes as recovery forecast, solutions effectiveness and economic world wide impact calculations of every and any phenomena?

Whichs are the components that increase threats after a phenomena strike?

Video 4 of 7: The Scale Table

From a traffic jam to a nuclear evacuation, the R.D.M.S. establish "easy - data - relation" with authorities and population answer, helping to the "meaning - making - facts", so any decision can be understood as part of a necessary resilience path, framed in a whole context.


From a range of 0.1  to 10, grouped in 5 categories, related to vital and non vital interaction patterns the R.D.M.S. offer a comprensive meaning of the crisis. 

Video 5 of 7: Benefits

What can be done through the R.D.M.S.?

Can the social and political impact be understood? ...  R: Yes

Can priorities be establish dynamically?...                     R: Yes

Can solution effectiveness be measured?...                   R: Yes

Can recovery forecast be calculated?...                         R: Yes

Can objective comparisons to learn, be established?    R: Yes

Video 6 of 7: Where does the information comes from

Government special satellite devices guarantee official income information.

Civil population participation on/line and off/line, are enable.

The R.D.M.S. build an historical data base, allowing "big data analysis" to identify tendencies.
