!3 years here in Chiang Mai. I have not studied the broader issue and so I can only relate my own experience having lived in L&H (Maejo), Condo and rental home at 118 & 121 area (Sansai), Phimuk 1 (Sansai Noi) and now Saraphi. Only real damage was observed in 2011 upon first retiring in July 2011. Those who were here will well remember August that year. Chiang Mai flooded with the Mae Ping going over its banks. High electric poles along 121 were brought down. L&H flooded, I had to go to a hotel for a couple of nights. Other than that, I have been pleased and a bit surprised after noting the electric wire "rats nests" throughout Thailand. Oh, my electric has gone off but my experience has been that it is restored in short order. It is, in my experience it is off, usually, the longest one hour. If the electric went off where I lived in the USA, it was serious and would last the better part of a day or longer. But then I lived on the fringe of "tornado alley". Ice storm in 2009 left most ofwestern Kentucky without electric the better part of two weeks.
