Mysterious Peruvian Meteor Disease Solved
Technician writes "The meteor that crashed in Peru caused a mystery illnesses. The cause of the illness has been found. The meteor was not toxic. The ground water it contacted contains arsenic. The resulting steam cloud is what caused the mystery illness.
"The meteorite created the gases when the object's hot surface met an underground water supply tainted with arsenic, the scientists said." There is a very good photo of the impact crater in the article. The rim of the crater is lined with people for a size comparison."
Fair enough. My sources are as follows. However, not a single one of them is from this article. And since they obviously contradict it, it would seem that there is NOT a unanimous agreement as to what happened.
The object, Woodman said, was metallic in nature and created a crater 42 feet wide and 15 feet deep. The impact also registered a 1.5-magnitude tremor on the institute's seismic equipment.Ronald Woodman is the director of the Peruvian Geophysical Institute.
Mid sized meteorites are not hot. I'll say it again: Mid sized meteorites are not hot. First, meteoroids are naturally cold. They've been out in the frigid blackness of space for many billions of years -- these rocks are cold down to their very center. Second, because of its size there's a good chance that this meteorite was originally part of a larger meteor that broke up anywhere between 60 and 30km above the surface. If that is the case, the larger meteor's cold interior would become the smaller meteor's cold exterior. Since hardly any surface heating takes place lower than about 30km, this cold surface doesn't warm up by any appreciable amount. Some meteorites, located soon after landing, have actually been reported to have frost on the surface due to their still cold interior.
There 'preliminary' analysis quoted in this article is contradicted by the following; In addition, Woodman stated that astrophysicist José Ishitsuka of Peru's Geophysics Institute, had collected samples of the meteorite and had confirmed that it contained a high degree of iron. It was reported that Ishitsuka retrieved a 3-inch magnetic fragment of the meteorite and has based his conclusion after studying its properties.
What I am attempting to say, is that there is NOT any 'proof' as to what this was, at least not yet. And to simply accept the explination that it was a meteor without the evidence to support it, is not acceptable in any scientific attempt at explaining what happened here. In time, it may be 'proven' to be a meteorite. But that time is not now. It is merely 'speculation' that is a meteorite. Lots of things that fall from space can have a 'high degree of iron', some of them are manmade.
