Trigger database

Setting a trigger is one of the essential components of establishing anticipatory humanitarian action. In the humanitarian and development context, triggers help provide decision-makers the necessary information to know when and where early action should take place and who and what is likely to be impacted. In line with the impact-based forecasting approach, the trigger model is developed based on a detailed risk analysis of natural hazards, including impact assessments of past disaster events, and analysis of exposure and vulnerability data. 

This database of triggers serves as a platform for practitioners to see what triggers are being formulated and to facilitate further exchange about the trigger development process.  

With the dropdown menus and search options below, you can find trigger information according to hazard, country, sector, lead time, or vulnerability and exposure indicators. The resulting list will provide you with trigger information, a description of the trigger activation process, forecast sources, stop mechanism, and additional details of activation history, where available. The trigger information can serve as a foundation for further research and discussion when developing EAPs and anticipatory action in new contexts. 

Growing this database and keeping it up to date is a community effort. If you or your organization would like to add to the trigger database, please download and fill out the following form and send it to Irene Amuron and the Anticipation Hub.

Volcanic ash EAP Ecuador

  • Hazard(s)

    Volcanic Ash

  • Countries

    Ecuador

  • Lead time

    Long term

  • Risk indicators

    Socio demographic, Geographic location, Livestock

  • Sector(s)

    Early warning, Health, Livelihoods, Cash, Food security

  • Description

    The volcanic ash EAP trigger is based on the emission of three special forecasting reports produced by the Ecuadorian Geophysical Institute of the National Polytechnic School (IGEPN). Special Report A is released when a significant change in the internal activity of the volcano is observed. Special Report B will detail the increase or decrease of internal activity and provide an update on eruptive activity with an approximate lead time of 7 days. Finally, Special Report C will detail the most likely scenarios and possible impact on the community with a lead time of 24 hours. These three reports are analyzed and combined with an intervention map to identify where the early actions will be implemented.

    Further info:

    Report A does not define a lead time. Special Report  B and/or Special Report C shall  indicate the most likely scenarios and lead times when released (approximately 7 days for Special Report  B and 24 hours for Special Report C)

  • Lead Time:

    2 month (estimated)

  • Forecast Source

    National:

    Institute of Meteorology and Hydrology (INAMHI) & Geophysical Institute of the National Polytechnic School (IGEPN)

  • Risk indicators (Vulnerability & exposure)

    Livestock:

    Number of cattle head per province near volcanoes

  • Probability

    N/A

  • Return Period

    Dependent on each volcano

  • Stop Mechanism

    Upon issuance of Special Report B, which indicates update of conditions of the volcano's internal activity. When this report indicates that the volcano's internal activity (sisimcity, degassing and deformation) has decreased and stabilized, intervention will be lifted.

Trigger(s)

Dzud EAP Mongolia

  • Hazard(s)

    Dzud

  • Countries

    Mongolia

  • Lead time

    Long term

  • Risk indicators

    Socio demographic, Geographic location, Livestock

  • Sector(s)

    Livelihoods, Cash, Food security

  • Description

    The dzud EAP trigger is based on the Dzud Risk Map (DRM) released annually in November. If the DRM indicates that 20% of 3 or more provinces are at very high risk from the dzud (red) the EAP will be activated.

  • Lead Time:

    3 months

  • Forecast Source

    National:

    National Agency for Meteorology and Environmental Monitoring (NAMEM) in collaboration with University of Nagoya, Japan 

  • Risk indicators (Vulnerability & exposure)

    Socio demographic:

    Poverty, single-headed households, children <5, elderly, pregnant & lactacting women 

    Geographic location: 

    Location of herders and livestock

    Livestock:

    Number of livestock, types/breeds, location

  • Probability

    N/A

  • Return Period

    5 years

  • Stop Mechanism

    If the dzud risk map is updated and the risk level doesn’t reach the trigger activation threshold, some early actions stopped. Difficulty to facilitate stop mechanisms on cash transfers.

  • EAP activation history

    • Trigger: 8 Jan 2020 
    • EA completed: 8 March 2020
