ministre uzsvēra, ka tika iesaistīti ļoti daudz iekšlietu struktūru darbinieku – Valsts ugunsdzēsības un glābšanas dienests, Valsts policija, kā arī armijas karavīri. “Puse Valmieras policijas sargāja apkārtni, domājot, ka tas ir kaut kas vēsturisks, lai nepazūd pierādījumi zinātniekiem,”

Kas sūtīja policiju, kas armiju, kas ugunsdzēsējus, kas lika ko sargāt - tos visus būtu jāpatriec no amatiem, ja tā licēja ministre, tad, lai sedz izniekotos līdzekļus!

Meteorite Strikes Peru!
Lionel E. Jackson Jr., Peter Brown, Jay Melosh and Dolores Hill

Geologists rush to study the crater and pieces left behind

From whence it came Print Exclusive
Meteorite classification — what’s in a name?
Crater in Carancas, Peru
Lionel Jackson
The meteorite that struck Carancas, Peru, left behind a 13.5-meter-wide crater.

It was an ordinary Saturday morning in Carancas, Peru, a small village along Lake Titicaca only a few kilometers south of the Bolivia-Peru border. Residents of this indigenous rural community were going about life as usual, tending to llamas and sheep, chatting with neighbors in the native Aymara language and preparing for lunch. Little did they know that their lives were about to change.

At 11:45 a.m. on Sept. 15, 2007, a fireball as bright as the sun appeared in the sky above the southern end of Lake Titicaca. Thousands of observers across the region saw it flash across the sky and heard loud explosions.

The fireball struck Earth right in Carancas. The nearest eyewitnesses were only 300 meters away when the final impact hit and exploded. The event blasted out a nearly circular crater with a diameter slightly longer than a school bus. The explosion was violent enough to hurl ping-pong ball-sized fragments of mud up to five centimeters in diameter as far away as 200 meters and punch a hole in the roof of an adobe dwelling 150 meters away. Those closest to the fireball reported seeing white smoke rise from the crater and smelling foul, sulfurous odors. About two dozen people in Carancas sought medical attention following the impact, with complaints ranging from headaches to intestinal problems. Then the pandemonium set in.

Not long after the meteorite struck the ground, word of the event spread like wildfire through the Internet and media. “METEORITE CRASHES INTO PERU: SCORES ILL” read headlines worldwide. To hear the media tell it, some 600 people fell ill from toxic fumes released by a gigantic meteorite that left behind a gaping, 30-meter-wide crater in this sleepy mountain town. In reality, the gaping crater was less than half the size widely reported. And the few short-lived symptoms reported by townsfolk were more likely the result of the emotional shock or concussive force of the massive explosion, rather than toxic gases. Nonetheless, for a brief period, this rural community was in the global media spotlight. That waned quickly, but interest in the crater was only starting to blossom among scientists and treasure-seekers.

Fragments of the Carancas meteorite, such as this one, range in size from a couple of millimeters to about the size of a racquetball.

Within 36 hours of the strike, geologists from INGEMMET (Peru’s geological survey) arrived in Carancas to study the crater. They were followed over the coming months by an onslaught of geologists — and collectors hoping to capitalize on the impact by finding pieces of the meteorite to sell. For scientists, this presented an incredibly rare opportunity: the chance to study fragments of a meteorite and a fresh impact crater. We could not pass it up.

What are the chances?
Aspects of the Carancas event are both common and rare — which is part of the reason we scientists were so keen to study it.

When the meteor entered Earth’s atmosphere, it moved with as much energy as about 100 tons of exploding TNT, more than any non-nuclear military bomb. Space scientists estimate that meteoroids with similar energies enter Earth’s atmosphere approximately once a week. Roughly three-quarters of them go unnoticed as they occur over the open ocean. Only a few would produce craters of any significant size if they struck land. As a result, documented crater-producing impacts from any type of meteorite are very rare within a human lifespan.

However, one such impact occurred in February 1947 over the former Soviet Union. A meteorite that had perhaps 100 times more energy than the Carancas meteorite fell through the atmosphere to Earth. The Sikhote-Alin meteorite fragmented into pieces, producing a field of craters. The largest was double the size of the Carancas crater. Another impact near Sterlitamak in Russia on May 17, 1990, produced a crater more similar in size to the one at Carancas.

Both of these impactors were iron meteorites. Carancas, however, is a stony meteorite called a chondrite, which is perhaps the most astounding aspect of this event, as chondrites usually break up in the atmosphere. Surviving fragments fall to Earth at less than the speed of sound (340 meters per second at sea level) and rarely have the energy to make craters. The largest intact stony meteorite ever recovered as one intact specimen occurred as part of the Jilin, China, meteorite shower in 1976. It weighed more than 1,700 kilograms. In that case, however, the crater was only two meters across. In all, researchers have identified nine small craters (10 to 100 meters in diameter) on Earth prior to Carancas (there are other larger craters as well). Seven of these occurred during the last 10,000 years, and the other two occurred sometime during the last several million years. All were produced by iron meteorites, except Carancas.
Indigenous Aymara people

The indigenous Aymara people were going about their business, tending to livestock and visiting with neighbors when the meteorite struck.

The meteorite
It did not take long for the local people to realize that this was a meteorite impact and to comb the ground for meteorite fragments. The finds proved to be a bonanza for some lucky individuals who sold pieces for hundreds of dollars to professional meteorite hunters descending on the site. Samples were on sale on the Internet within a month of the event — in fact, a quick search of eBay shows that some of these meteorite fragments are still for sale. Fortunately, locals and meteorite hunters also provided samples to researchers.

Luisa Macedo, an INGEMMET geologist, traveled to Carancas from Lima to investigate the event and collect meteorite fragments for study. Back at INGEMMET’s laboratories, Macedo’s staff cut the samples into thin, polished sections for microscope study. That’s when they figured out it was a chondrite. The thin sections revealed that the Carancas meteorite was dominated by the same silicate minerals, such as pyroxene, olivine and feldspar, that are common in volcanic rocks on Earth. There were also bits of minerals rich in iron and nickel along with traces of iron sulfide, chromite and metallic copper. Macedo’s findings were released on the Internet only six days after the impact.

When samples reached the United States about two weeks later, the general chondrite classification was more precisely defined by a team from the Lunar and Planetary Laboratory at the University of Arizona in Tucson led by Harold Connolly. The meteorite was officially classified as an H4-5 S3 W0 breccia in the complex classification scheme that scientists use and given the name Carancas by the Nomenclature Committee of the Meteoritical Society.

Since the initial observation, planetary scientists have carried out extensive research on the meteorite and its crater. We have been able to further establish limits on the range of mass, velocity and impact angle responsible for forming the Carancas crater. As meteoroids pass through the atmosphere, they progressively vaporize and rapidly lose mass (a process called ablation) due to high temperatures generated by frictional heating. This heat also creates light, causing the meteoroid to streak across the sky like a giant fireball. Given the trajectory calculated for the Carancas meteoroid from infrasound data, it would have had an initial mass of six to 10 metric tons when it entered Earth’s atmosphere. Most of this mass ablated as it traveled through the atmosphere. The remaining kernel that struck Peru is estimated to have had a velocity in the range of 5,400 to 14,000 kilometers per hour (about five to 12 times the speed of sound) and a final mass upon impact on the order of a few metric tons (one to two cubic meters in volume).

Although the crater was the size of a suburban house, it is inconsequential compared with great impact craters such as the Chicxulub crater that underlies portions of the Yucatan Peninsula — and which is tied to the dinosaur extinction 65 million years ago. Scientists estimate that 180-kilometer-diameter crater was created by the impact of an object about 10 kilometers in diameter — 5,000 to 10,000 times larger than the diameter of the Carancas meteorite.

Tur jau tas trakums, ka sākums ir tajā vietā, kad kāds (un kurš tas bija?) to nosauca par meteorītu. Nezinu, vai Mūrniece spētu pierādīt, ka kaimiņmājas saimniece vai kāds tīnis nedrīkstētu kaut ko līdzīgu tam tā nosaukt. Drīzāk iespējams pierādīt, ka visi dienesti un speci (ieskaitot Mūrnieci) ir rīkojušies kā pēdējie lohi, un tam ir konkrēta un bezjēdzīga cena. Ja jau nav nekāda apdraudējuma dzīvībai vai īpašumam, tad ministrijai ir jārīkojas maķenīt intelektuālāk, t.i., racionālāk. Dzelteno "orgānu" kompetences pierādījums.
