Don't know which flood oil pan 4 referenced, but for the Yellow River in 1938 that's low.

https://en.wikipedia.org/wiki/1938_Yellow_River_flood
Quote:
The 1938 Yellow River flood (Chinese: 花園口決隄事件, literally "Huayuankou embankment breach incident") was a flood created by the Nationalist Government in central China during the early stage of the Second Sino-Japanese War in an attempt to halt the rapid advance of Japanese forces. It has been called the "largest act of environmental warfare in history" and an example of scorched earth military strategy.[1][2]
https://en.wikipedia.org/wiki/1938_Y..._of_casualties
Quote:
There is no way of accurately assessing the casualties: much of the population, including officials, had already fled, leaving no government control and no one to count the dead. In the shifting battles between bandits, Nationalists, Communists, and Japanese, counting casualties was not a high priority. The Nationalist government, after initially claiming that the breach was caused by Japanese bombing, used the heavy casualties to demonstrate the scale of sacrifice required of the Chinese people; it claimed that 12 million people had been affected by the flood, and in 1948 it estimated the number of deaths, including hundreds of thousands of Japanese who perished during the flooding, at 800,000. A 1994 PRC (People's Republic of China) official history of the war put the dead in the flood at 900,000 and the number of refugees at nearly 10 million. Scholars exploring the archives now give much lower figures: 400,000–500,000 dead, 3 million refugees, and 5 million people affected (another estimate puts the number of dead at 500,000, and the number of homeless at 500,000).[6]
Pre-Mao, so it's on Chiang Kai-shek,

Typhoon Nina 1975 triggered https://en.m.wikipedia.org/wiki/1975...ao_Dam_failure .
It was all started by the only notable solar storm in 1975 as it was a minimum year.

And nowadays many folks are scared the hell out about the EMPs released by a solar storm, as electronics are so much more intensively used. Once I inquired a teacher who also happens to work with avionics maintenance, and he said it's not really much a matter of concern.

He was possibly from the vacuum tube era.

You can track, statistically, the effects on cardiac and cognitive impairment at ground level.

Avionica are at a much higher level of hardening. There are two major troubles with EMP: flipping a critical bit in the RAM used for program storage thus crashing the program or disruption of controls sensor data. After some ungodly cost for a RNAV system, you want it to keep working in your hundred million dollar airplane.

Gm doesn't care much if your engine computer dies, it has replacements and your car isn't likely to have controlled travel into the side of a mountain with 300 souls onboard

That's why airplanes use at least 2 computers to run critical systems.
Military aircraft run at least 3 computers for flight controls. 2 computers in parallel then a 3rd computer that acts as a tie breaker incase the 2 parallel computers disagree.

The wiring loom is better protected against electromagnetic interferences in an aircraft than in some medical equipments for instance.
