Meteorite Causes Illness in Peru
eldavojohn writes "A meteorite struck in Peru on Saturday leaving cinders, rock & water boiling out of the ground. Villagers nearby reported headaches & vomiting and attributed it to the event. From the article, 'Seven policemen who went to check on the reports also became ill and had to be given oxygen before being hospitalized, Lopez said. Rescue teams and experts were dispatched to the scene, where the meteorite left a 100-foot-wide (30-meter-wide) and 20-foot-deep (six-meter-deep) crater, said local official Marco Limache.' It's not yet clear whether this is from the meteorite, gas trapped underground that was released or a chemical reaction between the two."
Ah, I suspect this was either not a meteorite or there is something else going on given that any meteor leaving a 30 meter wide and 20 foot deep crater (meteor being approximately 30 inches wide) is not going to hit the ground steaming hot. On the contrary, it will be cold as ice (or colder) given its composition and time for heating. However, I suppose it could also be a re-entry event from a satellite carrying a toxic payload like plutonium... After all, we have the remnants of many satellites and the debris associated with them still in decaying orbits and you can easily spot many of them. Some satellites particularly those from the former Soviet Union and China have a history of toxic components. Though I suspect we'll know soon enough if it were a satellite, it would have been tracked by numerous agencies and individuals who monitor that sort of thing.

Looking at the pictures, the ground looks like a prime area for fungus to release spores when disturbed, like anthrax.
It could be a downed satellite - maybe some hydrazine or something is causing the illness.
My vote is hydrazine. If you can smell that stuff, it'll make you sick. Sick from toxic effects of the chemical, not just sick to your stomach.

No. Chernobyl had issues, but the reason it melted down was that ALL of the safety features were disabled to run a test for the Soviet equivalent of the NRC.
The test in question was meant to determine how much power could be extracted from a nuclear plant in meltdown. Which information would allow them to plan better for dealing with meltdowns, should one happen.
Alas, to put Chernobyl into the near-meltdown condition required for the test, they had to disable all of the safety interlocks, then push the plant to the brink of a meltdown.
And when you push a nuclear plant to the brink of meltdown with ALL of the saftey interlocks disabled, bad things can happen.

There isn't a man-made object in space that could create a crater like that. The big ones like the ISS are too low density. The high density ones like the Russian Cosmos nuclear satellites aren't big enough. All of them would have a shallow entry angle that would result in a low velocity for anything that did hit the ground.
As you speculated, when events like this are reported, the various space agencies are usually very quickly able to identify possible satellites that may have entered during a given time frame. For example, a Russian booster entered over my home county about 10 years back. It had already been identified the next morning. Incidentally, it burned up completely. No crater.
Regarding a plutonium carrying satellite. Although I've mentioned such couldn't account for such a crater, there have been quite a few put into space. Cosmos 954, which failed to reach orbit and disintegrated over Canada (note that it was not designed to survive re-entry) is a notable example, but the Russians built dozens of these satellites. Actually, the Cosmos RORSATS were powered by uranium-fueled nuclear reactors, not plutonium RTG's. Anyway, when the RORSATS reached the end of their life, the fuel bundle was actually ejected by a small rocket into a 1000 km disposal orbit, which will delay their re-entry by several hundred more years. I suppose most of the satellite bodies themselves have already re-entered.
Interestingly, this has been found to be a rather major source of space debris, as some of the liquid sodium coolant was ejected simultaneously with but free from the core. Once free from the heat of the reactor, the liquid sodium hardens into little metal spheres.
