From Tafsir Maududi:
لَا يُكَلِّفُ اللَّهُ نَفْسًا إِلَّا وُسْعَهَا لَهَا مَا كَسَبَتْ وَعَلَيْهَا مَا اكْتَسَبَتْ رَبَّنَا لَا تُؤَاخِذْنَا إِن نَّسِينَا أَوْ أَخْطَأْنَا رَبَّنَا وَلَا تَحْمِلْ عَلَيْنَا إِصْرًا كَمَا حَمَلْتَهُ عَلَى الَّذِينَ مِن قَبْلِنَا رَبَّنَا وَلَا تُحَمِّلْنَا مَا لَا طَاقَةَ لَنَا بِهِ وَاعْفُ عَنَّا وَاغْفِرْ لَنَا وَارْحَمْنَا أَنتَ مَوْلَانَا فَانصُرْنَا عَلَى الْقَوْمِ الْكَافِرِينَ
Allah does not burden any human being with a responsibility heavier than he can bear. Everyone will enjoy the fruit of the good that one has earned and shall suffer for the evil that one has committed. (O Believers, pray like this to Allah: ) "Our Lord, take us not to task if we forget and lapse into error inadvertently. Lord! lay not on us the kind of burdens that You had lain on the people before us. Lord, lay not on us the kind of burden that we have not the strength to bear. Be kind to us, forgive us and show mercy to us. You are our Protector : help us against the disbelievers."
That is, "Allah will not call to account anyone for not doing something which he could not possibly do: nor will He punish him because he did not abstain from a thing, when he could not possibly abstain from it." It must, however, be clearly understood that an individual himself is not his own judge to decide what he can do and what he cannot do. It is Allah, Who will decide what a certain person could do and what he could not do.
The verse is talking about that Allah controls what we do and can't do. We can't decide it. Allah is saying that he will not test those people who did not do something they are unable to do. For example, if someone cannot fast because of a permanent condition and the time for Ramadan comes and they don't fast, Allah will not call for account why they didn't fast because the reason they are unable to fast is because Allah decided that they are unable to fast and no one but Allah can decide it.
This verse is not compatible with natural disasters and has nothing to do with it.
