EM-DAT sources used in the chart (disasters and impacted people)
EM-DAT contains essential core data on the occurrence and effects of over 18,000 mass disasters in the world from 1900 to present. The database is compiled from various sources, including UN agencies, non-governmental organisations, insurance companies, research institutes and press agencies. A disaster has to meet at least one of the following criteria to be listed: 10 or more people killed, 100 or more people affected, declaration of a state of emergency, call for international assistance.
EM-DAT: The OFDA/CRED International Disaster Database – www.emdat.be – Université catholique de Louvain – Brussels – Belgium.
Munich RE sources used in the chart (maps detailing the disasters)
The historical natural hazard archive of Munich Re is the most comprehensive collection of data worldwide. Munich Re NatCatSERVICE (the data found in the total disasters and Global Maps shown above) evolved from this historical archive in 1974. The NatCatSERVICE includes around 28,000 data sets. The oldest registered event relates to the eruption of Mount Vesuvio on August 24 in 0079 and the consequent destruction of Herculaneum and Pompeij. The statistics/analyses provided here are the property of Munich Reinsurance Company.
FRVs calculation and assumptions
The number of FRVs required is calculated by dividing the total amount of impacted people by 650 (the amount of people that a single FRV can feed for 30 days straight). It is assumed that all people impacted by a major disaster would need food for at least one day and up to 30 days following the disaster.
WRVs calculation and assumptions
The number of WRVs required is calculated using a ratio of eight FRVs to one WRV. This ratio is derived from the assumption that each person needing aid after a major disaster will require 12 gallons of clean potable water per day (for drinking, hydrating the emergency food provided in the FRV, sanitation needs, etc.). While there are different sizes and rates of water filtration vaults, we use a 8:1 ratio for simplicity.
SRVs calculation and assumptions
The number of SRVs required is calculated using a ratio of fourteen SRVs to one WRV. This ratio is derived from the assumption that it takes fourteen SRVs to house and support 650 people for one day. It is assumed that all people impacted by a major disaster would need shelter for at least one day and up to thrity days following the disaster.
Overall ratios used in estimating
8 FRV = 1 WRV = 14 SRV
*Total number of Disasters in the US for 2012
The Tropical Storm Sandy was included in this list of disasters along with the 455,000 people evacuated by the storm. During the time of this chart creation (9/22/2013), this storm was not listed in the EM-DAT database yet.
