There are four rings around the epicentre, with boundaries set by the KNMI, the Dutch meteorological institute. Because the tremors were weaker further away and the chance of damage there is smaller, the possible compensation in the inner two rings is higher. The new approach for those rings is now being worked out, and the Commissie Mijnbouwschade, the mining damage commission that handles the damage from this earthquake, expects to start on the first claims from them after the summer. A scheme for the outer two rings has yet to be drawn up and is expected later this year.
Claims have to be handled more simply because the commission and the Instituut Mijnbouwschade Groningen (IMG), the Groningen mining damage institute, have received so many. The ministry, the commission and the gas company Nederlandse Aardolie Maatschappij (NAM) have agreed conditions for this: compensation must be in proportion to the damage, the scheme must be clear and work in practice, and the cost of investigations must not get out of line with what is paid out. Exactly what the schemes will involve is not yet known; the commission will tell those who reported damage as soon as it is clear.
