The next step is to determine the potential wildfire hazard.  **How our wildfire model works**  To calculate wildfire hazard, Vibrant Planet evaluates burn probability and fire intensity together. These calculations are powered by Pyrologix, a Vibrant Planet company. Areas with the highest hazard generally contain the greatest combination of burn probability and fire intensity.  - Burn probability (FSim) - the probability that a geographic location (30-m pixel) will experience a wildland fire. Modeled using FSim, which simulates the growth and behavior of hundreds of thousands of large fire events, based on historical fire occurrences, weather, terrain, and fuel.  ![](https://go.vibrantplanet.net/hs-fs/hubfs/Screenshot%202024-08-23%20at%201-49-27%E2%80%AFPM-png.png?width=688&height=432&name=Screenshot%202024-08-23%20at%201-49-27%E2%80%AFPM-png.png) - Fire intensity (wildEST)- the flame length that the pixel is likely to experience when it burns. This calculation uses a model developed by Pyrologix that performs 200+ simulations and uses local fuel, weather, and topography to generate estimates of contemporary flame lengths within a given pixel. ![](https://go.vibrantplanet.net/hs-fs/hubfs/Screenshot%202024-08-23%20at%201-49-56%E2%80%AFPM-png.png?width=688&height=361&name=Screenshot%202024-08-23%20at%201-49-56%E2%80%AFPM-png.png) *Wildfire hazard mapped in Truckee, California* Wildfire hazard data appears as color-coded polygons over a landscape. The darker the polygon, the higher the hazard. This information feeds into your future risk reduction strategy, helping predict how exposed resources on the landscape are to disturbance.  Next, let’s [explore how we help you map resources and assets of value](https://go.vibrantplanet.net/learn/strategic-areas-resources-assets?hsLang=en), so you can ultimately understand the opportunities to increase the resilience of the things that matter most.  - [Learn the Methodology](https://go.vibrantplanet.net/learn/learn-the-methodology?hsLang=en#main-content) - [Assess your landscape](https://go.vibrantplanet.net/learn/learn-the-methodology?hsLang=en#assess-your-landscape) - [Pinpoint areas for scenario planning](https://go.vibrantplanet.net/learn/learn-the-methodology?hsLang=en#pinpoint-areas-for-scenario-planning) - [Calculate wildfire hazard](https://go.vibrantplanet.net/learn/learn-the-methodology?hsLang=en#calculate-wildfire-hazard) - [Determine highly valued resources, assets, and areas](https://go.vibrantplanet.net/learn/learn-the-methodology?hsLang=en#determine-highly-valued-resources-assets-and-areas) - [Utilize planning areas and distinct management areas](https://go.vibrantplanet.net/learn/learn-the-methodology?hsLang=en#utilize-planning-areas-and-distinct-management-areas) - [Assess risk](https://go.vibrantplanet.net/learn/learn-the-methodology?hsLang=en#assess-risk) - [Understand possible management options for your area](https://go.vibrantplanet.net/learn/learn-the-methodology?hsLang=en#understand-possible-management-options-for-your-area) - [Build a common operating picture](https://go.vibrantplanet.net/learn/learn-the-methodology?hsLang=en#build-a-common-operating-picture) - [Emphasize management objectives](https://go.vibrantplanet.net/learn/learn-the-methodology?hsLang=en#emphasize-management-objectives) - [Build prioritized, sequenced project plans](https://go.vibrantplanet.net/learn/learn-the-methodology?hsLang=en#build-prioritized-sequenced-project-plans) - [Gather consensus amongst partners](https://go.vibrantplanet.net/learn/learn-the-methodology?hsLang=en#gather-consensus-amongst-partners) - [Review project statistics](https://go.vibrantplanet.net/learn/learn-the-methodology?hsLang=en#review-project-statistics) - [Get ready for the field](https://go.vibrantplanet.net/learn/learn-the-methodology?hsLang=en#get-ready-for-the-field) - [Glossary](https://go.vibrantplanet.net/learn/glossary?hsLang=en) - [Use the Platform](https://go.vibrantplanet.net/learn/use-the-platform?hsLang=en) - [HVRAAs](https://go.vibrantplanet.net/learn/hvraas?hsLang=en) - [New Features](https://go.vibrantplanet.net/learn/new-features?hsLang=en) - [Product Guide](https://drive.google.com/file/d/149qq3U4d6Z1fCQhYBDQArfqRYSEhMnzP/view) - [STELA Schema](https://docs.google.com/spreadsheets/d/18dQDbBqMdVwCj2b_pZYlm8ZxlsFrd-cWNBmkM1jY0U8/edit?gid=0#gid=0&fvid=881275009) [![Chill listening crop-3](https://go.vibrantplanet.net/hs-fs/hubfs/Copy%20of%20VP_Avatar_Color_RGB%20(2).png?width=24&height=24&name=Copy%20of%20VP_Avatar_Color_RGB%20(2).png "Chill listening crop-3")](https://www.vibrantplanet.net/) Vibrant Planet | Copyright 2024 Copyright © 2025, Vibrant Planet
