Professor J. Dooge was elected Chairman of the working group on atmospheric phenomena. Mr. P. J. Meade was appointed Rapporteur. The Chairman initiated a general discussion on the questions the meeting needed to exam- ine, and invited UNDRO representatives to give additional guidance or explanations on detailed aspects of vulnerability analysis. The Chairman then called upon the representatives of other organizations (see Annex II) to make statements. AI1 statements agreed on the importance of the questions to be considered by the meeting and examples were given ‘of the necessity to carry out vulnerability anaIysis during the pre-investment stage of development projects in disaster-prone countries. In view of its special relevance to the work of the meeting, the Chairman asked Mr. Fournier d’Albe (UNESCO) to describe the UNESCO programme on earthquakes which had been in operation for some 18 years. Mr. Foumier d’Albe said that the programme had evolved from a purely scientific programme in seismology to a widely multi-disciplinary attack on the problem of earthquake risk management, He outlined the steps by which it had been possible to arrive firstly, at an assessment of earthquake hazard in terms of describing ground motion which could be used directly by engineers in the design of earthquake resistant structures; secondly, at an assessment of the vulnerability of human lives, property, productive capacity, etc., to seismic ground movements; and, finally, at an assessment of risks, defined as a probability of loss, as well as the use of this risk assessment in pre-disaster planning, notably in the elaboration of long- term preventive measures. UNESCO’s programme on natural hazards also included work on volcanic eruptions and landslides, in which a similar approach had been adopted. Mr. Fournier d’Albe felt that, despite differences in vocabulary, UNESCO and UNDRO had in fact evolved similar methodologies and that it should not be difficult at this meeting to reach agreement on 
**Analysis**
The text appears to be discussing a meeting focused on disaster risk management and vulnerability analysis, with a specific focus on earthquakes and natural hazards. The language used is technical and scientific, and the discussion involves organizations and experts in the field. This suggests that the category is related to natural disasters and environmental issues.
