# Extreme disaster scenarios In a typical Casa setup, the user is instructed to store their keys in separate locations to protect against key loss in case of a disaster, such as at home, their office, and a bank vault. If any one of those keys survives, the user will be able to recover their funds. However, in case of a disaster that destroyed a whole city (nuclear bomb or conventional bombardment, exceptionally large earthquake, tidal wave or major flood, etc.) all three of the keys might be lost. **Mitigation:** * For exceptionally large balances, store one key in a different city / state / country. * Store (only) 1 hardware device seed phrase on [metal plates](https://seed-storage-reviews.bitcoin.page/), along with your Sovereign Recovery instructions, in multiple locations. This will ensure that even if a physical attacker compromises the seed phrase, they won't be able to spend your funds. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.casa.io/wealth-security-protocol/remaining-attack-vectors/extreme-disaster-scenarios.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
