For those who are able to and want to help, there's a GoFundMe campaign right now to help the studio recover [0]. There isn't much of an explanation of what the money will go towards, but it's better than doing nothing IMO.
I'm not a huge consumer of anime/manga, but some of my favorites (namely, Nichijou and Full Metal Panic) have come from this studio. I'm also aware that the industry as a whole is considered to be in a bad state right now, with this event certainly not helping things.
My condolences to those effected by this. I do hope, though, that this serves as a springboard for better things to come for the industry.
