Liquidations

Introduction
A liquidation is a process that occurs when a borrower's health factor goes below 1 due to their collateral value not properly covering their loan/debt value. This might happen when the collateral decreases in value or the borrowed debt increases in value against each other. This collateral vs loan value ratio is shown in the health factor.
In a liquidation, up to 50% of a borrower's debt is repaid and that value + liquidation fee is taken from the collateral available, so after a liquidation that amount liquidated from your debt is repaid.
How much is the liquidation penalty?
The liquidation penalty (or bonus for liquidators) depends on the asset used as collateral. You can find every assets' liquidation fee in the risk parameters section.​
Can you give me an example?

Bob deposits 10 ETH and borrows 5 ETH worth of DAI. 
If Bob’s Health Factor drops below 1 his loan will be eligible for liquidation. 
A liquidator can repay up to 50% of a single borrowed amount = 2.5 ETH worth of DAI. 
In return, the liquidator can claim a single collateral which is ETH (5% bonus).  
The liquidator claims 2.5 + 0.125 ETH for repaying 2.5 ETH worth of DAI.
How can I avoid getting liquidated?
To avoid liquidation you can raise your health factor by depositing more collateral assets or repaying part of your loan. By default, repayments increase your health factor more than deposits. Also, it's important to monitor your health factor and keep it high to avoid a liquidation. Keeping your health factor over 2, for example, gives you more of a margin to avoid a liquidation.  
Can I participate in the liquidations ecosystem?
Yes, liquidations are open to anyone, but there is a lot of competition. Normally liquidators develop their own solutions and bots to be the first ones liquidating loans to get the liquidation bonus. 
You can find more details in the developers liquidation section.
