Great Bhola Cyclone

November 12, 1970, afternoon or early evening, Tazumuddin, East Pakistan
(probably best November 13, 1970, about 4:00 AM, Chittagong)

This is the deadliest tropical cyclone of all time, killing over 500,000 people (primarily from storm surge up to 30' high flooding the Ganges) and causing $86.4 million in damages ($558 million in 2019 value). Three-minute sustained winds were 115 mph at hits peak, with one-minute sustained winds of 150 mph.

It made landfall near Chittagong on the East Pakistan (now Bangladesh) coast the afternoon or early evening of November 12, with storm surge eradicating several villages and destroying crops across the region. The Tazumuddin district was hardest hit: nearly half its population died; therefore, I have chosen it for the location of study.

This cyclone had even greater repercussions than the immediate storm consequences, because the Pakistani government came under severe attack for its mishandling the disaster, which eventually triggered the Bangladesh Liberation War that ultimated in the creation of the nation of Bangladesh. (It was this cascade of events that led George Harrison to create his epochal Concert for Bangladesh in response to pleas by Ravi Shankar.)

While typing this, I just realized I had written this up before. I might want to reconsider some of its choices, but here is the text, relocated from a different spot.
The storm sometimes known as the "Great Bhola Cyclone" caused between 300,000 and 500,000 deaths when the storm surge overwhelmed island and tidal flats along the Bay of Bengal.

I need to add this to the book since it remains "the deadliest tropical cyclone ever recorded." It formed over the Bay of Bengal, intensified as it travelled north, Comparing sources, I find that it made first landfall on the coast of East Pakistan (now Bangladesh) on during the night of November 12 (or, actually, into the 13th). This was the natural disaster that motivated George Harrison to produce his "Concert for Bangladesh" the following year.

The place of landfall was at the coast at Chittagong (the city is within a few miles of the coast). It appears to have made landfall at 23:00 UT, or about 4:00 AM the next morning in Bangladesh.
