Chelyabinsk: from frontier town to industrial colossus

Chelyabinsk. "Sphere of Love," by Victor Mitroshin. Erected in 2000, this sculpture consists of four bronze trees surrounding two kissing figures under a dome of blue Italian glass. It has become the city's beloved calling card. July 13, 2003.

Chelyabinsk, located on the Miass River the southeastern Ural Mountains, is one of those largely ignored workhorses that form the backbone of Russian heavy industry. When the town’s relative obscurity was broken by a spectacular encounter with a meteorite in February 2013, it seemed that few outside observers knew much about this seventh-largest city in Russia. But Chelyabinsk has a varied architectural heritage that reflects profound social changes over the past century.

View of Chelyabinsk down the Miass River. Visible on far side are brick commercial buildings with Cathedral of Nativity of Christ (left) and Convent of the Hodegetria Icon of the Virgin (far right) - both demolished in the Soviet period. Late summer 1909.

Russian chemist and photographer Sergei Prokudin-Gorsky discovered some of the town’s architectural gems in Summer 1909, when he made his first trip to the Urals. The journey was part of an expansion of his project to photograph the diversity of the Russian Empire in the early 20thcentury. In May 1909, Emperor Nicholas II invited Prokudin-Gorsky to the imperial residence at Tsarskoe Selo to show his images of Russia through an elaborate projector. Following this presentation, the photographer gained the patronage of the imperial court to continue his travels, thus accelerating the pace and the scope of his work.

Frontier bulwark               

Chelyabinsk was founded in Autumn 1736 as part of a chain of forts constructed to protect supply lines from the granaries of western Siberia to the new Orenburg territory on Russia’s southern frontier. Cossack troops and settlers moved into the vast steppes roamed by Bashkir tribes, who responded with frequent attacks on Russian supply routes and outposts. By 1739, the Chelyabinsk fort had a population over 1,000.

Chelyabinsk. Late 19th-century brick commercial buildings on Kirov (formerly Ufa) Street. July 13, 2003.

Situated in a region rich in metals and foundry towns such as Kasli , Chelyabinsk remained a local market town for over a century. Its placid existence was broken by the settlement’s capture for two months in 1774 during a widespread, prolonged rebellion of serfs, Cossacks and Bashkirs led by Emelyan Pugachev.

Church of St. Alexander Nevsky, southeast view. Built in 1907-11 to a design by the prominent architect Alexander Pomerantsev. Closed in 1930, converted to planetarium. Restored in 1980s as concert hall. July 23, 2003.

The town’s growth advanced rapidly in the 1890s with the construction of the Trans-Siberian Railroad, which made Chelyabinsk a major junction in the southern Urals and a gateway to the east. Stimulated by agricultural reforms and promises of rich lands in Siberia, thousands of peasant families passed through resettlement centers in Chelyabinsk, where they received rudimentary care and supplies for the arduous trip to Siberia.

Alexander Kuznetsov Tea-Sorting Factory. Built in 1904, the Kuznetsov factory was among Russia's major tea processing facilities. By the time of Prokudin-Gorsky's visit it employed some 2,000 workers. July 12, 2003.

By 1897 the town had a diverse population of 20,000 inhabitants, including a Jewish community whose synagogue still functions. The pre-revolutionary decades witnessed the construction of numerous Orthodox churches, some of which have been restored in the post-Soviet period. Chelyabinsk also has several mosques.

Trinity Church, south view. Built in 1909-14, closed in 1929 and adapted to Regional History Museum. Returned to Orthodox Church in 1990, restored in 1993. July 23, 2003.

Commercial growth at the turn of the 20th century was boosted by agriculture and the construction of grain elevators. The transfer to Chelyabinsk of the main eastern customs point meant that the lucrative trade in Chinese tea was now processed in the town’s tea sorting plants. All of this was enabled by the railroad.

Chelyabinsk Synagogue. Built in 1903-05, the synagogue was closed in 1929 and converted to club for Chelyabinsk Tractor Factory. Returned to Jewish community in 1992 and restored in 1999-2000. July 12, 2003.

Revolution and industrialization

In the decade following Prokudin-Gorsky’s visit war, revolution and civil war took their toll, yet Chelyabinsk recovered and tripled its population by 1926. The launching of the Soviet Union’s first five-year economic plan in 1928 and the related collectivization of agriculture meant massive social upheaval. But for Chelyabinsk, the rapid march toward industrialization transformed its appearance and quadrupled its population in just over a decade.

Yalyshev department store, early 20th century. Its modernistic style exemplifies the rapid growth of Chelyabinsk before World War I. July 12, 2003.

A giant tractor factory was intended to launch Soviet agriculture into the machine age, and with the addition of a metallurgical plant, Chelyabinsk joined Magnitogorsk in producing steel and steel products. As a sign of the new age, administrative buildings and housing projects arose in a functional Soviet style.

State Bank Grain Elevator. Built in 1914-16 with advanced reinforced concrete technology as part of a national program for grain storage centers. Used until 1990s, then partially demolished. July 12, 2003.

With the outbreak of war on the Eastern front in June 1941, many military-industrial plants from the western Soviet Union were evacuated to Chelyabinsk, and local factories were reconfigured to produce weapons. The converted tractor factory produced tanks in such numbers that it became known as “Tankograd” (Tank City).      

 With the reconstruction of the country after the war, demand increased for Chelyabinsk steel and machinery. The region also became a center for research and production of atomic weapons.

This industrial, technological and military surge came at a price, as Chelyabinsk gained a reputation as one of the most polluted cities in the Soviet Union. In 1957, nuclear waste stored at the Mayak atomic facility located 45 miles northwest of Chelyabinsk exploded in one of the worst such catastrophes before Chernobyl.

View across Miass River toward Kirov (formerly Ufa) Street. July 13, 2003.

Post-Soviet renaissance

In the 1990s, Chelyabinsk and its heavy industry experienced severe financial challenges. With sardonic humor, locals noted that at least the air was easier to breath. The economic situation has now rebounded. The Chelyabinsk Metal Plant — part of the global Mechel Company — and the city’s tractor factory once again employ thousands.

Naum Orlov Drama Theater. Begun in 1973 and opened in 1982, the new Chelyabinsk drama theater has entrances framed with Kasli cast-iron art. July 12, 2003.

The city’s many institutions of higher education — led by South Urals State University and Chelyabinsk State University ­— have contributed greatly to this recovery. Chelyabinsk is also the seat of both a metropolitanate and a bishopric of the Russian Orthodox Church. The bustling red brick town that Prokudin-Gorsky photographed from the Miass River has managed to reunite its cultural and spiritual heritage with contemporary development.                      

Monument to Chelyabinsk volunteers who joined the Urals Volunteer Tank Corps. Formed in 1943, the tank troops fought their way from Oryol to Berlin. Sculptor: Lev Golodnitsky. Unveiled in May 1975. July 13, 2003.

In the early 20th century the Russian photographer Sergei Prokudin-Gorsky devised a complex process for color photography. Between 1903 and 1916 he traveled through the Russian Empire and took over 2,000 photographs with the process, which involved three exposures on a glass plate. In August 1918, he left Russia and ultimately resettled in France with a large part of his collection of glass negatives. After his death in Paris in September 1944, his heirs sold the collection to the Library of Congress. In the early 21st century the Library digitized the Prokudin-Gorsky Collection and made it freely available to the global public. A number of Russian websites now have versions of the collection. In 1986 the architectural historian and photographer William Brumfield organized the first exhibit of Prokudin-Gorsky photographs at the Library of Congress. Over a period of work in Russia beginning in 1970, Brumfield has photographed most of the sites visited by Prokudin-Gorsky. This series of articles will juxtapose Prokudin-Gorsky’s views of architectural monuments with photographs taken by Brumfield decades later.

Earth is continuously colliding with fragments of asteroids and comets of various sizes. The largest encounter in historical times occurred over the Tunguska river in Siberia in 1908, producing 1 , 2 an airburst of energy equivalent to 5–15 megatons of trinitrotoluene (1 kiloton of trinitrotoluene represents an energy of 4.185 × 10 12 joules). Until recently, the next most energetic airburst events occurred over Indonesia 3 in 2009 and near the Marshall Islands 4 in 1994, both with energies of several tens of kilotons. Here we report an analysis of selected video records of the Chelyabinsk superbolide 5 of 15 February 2013, with energy equivalent to 500 kilotons of trinitrotoluene, and details of its atmospheric passage. We found that its orbit was similar to the orbit of the two-kilometre-diameter asteroid 86039 (1999 NC43), to a degree of statistical significance sufficient to suggest that the two were once part of the same object. The bulk strength—the ability to resist breakage—of the Chelyabinsk asteroid, of about one megapascal, was similar to that of smaller meteoroids 6 and corresponds to a heavily fractured single stone. The asteroid broke into small pieces between the altitudes of 45 and 30 kilometres, preventing more-serious damage on the ground. The total mass of surviving fragments larger than 100 grams was lower than expected 7 .

Extended data figures and tables

Extended data figure 1 visibility and orbital evolution of chelyabinsk asteroid in the past..

The results of backward integration of Chelyabinsk nominal orbit (red) and its 1,000 clones (black dots). a , Apparent magnitude as seen from the Earth at 30-day intervals during past 10 years. Green, mean of all clones. Plotted only for elongations >45° from the Sun. b , Minimum orbit intersection distance (MOID) between the Chelyabinsk orbit and the osculating orbit of asteroid 86039 during the past 2,000 years. c , Change in velocity required to reach Chelyabinsk orbit from the orbit of 86039 at MOID during the past 2,000 years.

Extended Data Figure 2 Light curve of Chelyabinsk superbolide in relative units and fragmentation altitudes as determined from sonic booms.

The luminous signal was computed in relative units from pixel sum values from substantial parts of the images, and then normalized to 100. Corrections to bolide range and atmospheric extinction were applied but no attempt to convert the signal to absolute units was made (for the absolute light curve, see ref. 5 ). For each video, the measured pixel sum was corrected using the estimated changes of automatic gain control of the camera. The absolute timing was obtained from the Nizhny Tagil video (L1) and the height scale from the Beloreck video (video 14, or L4). The fragmentation altitudes were determined from the timing of secondary sonic booms and numerical ray-tracing modelling of the sonic wave’s propagation from the bolide to the video sites. The videos used are listed in Extended Data Table 1 . a , Bolide light curve as a function of time. b , The same data as a function of height compared with the computed source heights of sonic booms detected (as image failures) in the Mirnyi video (A19). The fragmentations are marked by vertical bars at the corresponding height. The length of the bar is proportional to the number of video frames affected by the failure. c , The compilation of sonic boom source heights from all 19 videos used for acoustic analysis.

Extended Data Figure 3 Deviation of fragment F1 from the main trajectory.

Frame from video 15. The time is counted from 3:20:20  ut . The labelled marks identify points on the main trajectory at the given altitude (in kilometres). E represents the endpoint of the main trajectory.

Extended Data Figure 4 Predicted impact position of fragment F1, computed with four different wind fields, compared with the position of the hole in the ice (‘Crater’).

The point marked F1 was computed with Verkhnee Dubrovo radiosonde data (0:00  ut ). Point K is for Kurgan radiosonde (0:00  ut ), point U is for the UKMO wind model for Chelyabinsk (12:00  ut ) and point G is for the G2S model (3:00  ut ) (ref. 31 in Supplementary Information ). The distance between U and K is 960 m. The distance between F1 and the crater is 220 m. We note that the position of the crater was not used for the computation of the F1 trajectory and impact point. The background image is from Google Earth and was taken one day after the impact.

Extended Data Figure 5 Identification of fragments in a series of images from video 7.

Fragments F1–F7 originated at lower altitudes ( ∼ 25 km), whereas fragments F11–F16 originated at higher altitudes (>30 km).

Extended Data Figure 6 Dynamics of the dust trail and fragments and predicted impact positions of observed fragments.

a , Altitude as a function of time for the lower edge of the thick dust trail (TE) and hotspots within the trail (HS1–HS3). The hotspots are identified in Extended Data Fig. 7 . b , Altitude as a function of time for the main body (M), lower fragments (F1–F7) and upper fragments (F11–F16), plotted together with the dust trail features. The fragments are identified in Extended Data Fig. 5 . The main body and trail were measured primarily from video 2; and the fragments, from video 7. c , Upward motion of the main hotspot (HS1) within the dust trail. Vertical deviation of the centre of the hotspot from the trajectory is plotted against time. The linear fit gives upward velocity of 0.08 km s −1 . d , Predicted impact positions and dynamic properties of observed fragments. Ablation coefficients and terminal masses were obtained by fitting the observed decelerations. Masses are valid for assumed spherical shapes and bulk densities of 3,300 kg m −3 . In some cases, the ablation coefficient could not be computed because there was an insufficient number of data points.

Extended Data Figure 7 Images of the dust trail at early stages.

a – c , Images from a single video site (video 2) located north of the fireball trajectory. Time is counted from 3:20:20  ut . Three distinct hotspots (HS1–HS3) are identified. The labelled marks identify points on the trajectory at the given altitude (in kilometres). The unlabelled marks above them identify points at the same geographic coordinates but 1 km higher. They are provided to assess the width of the trail. d , Image from video 14, from the southwest. It demonstrates that the width of the fully illuminated fresh trail was ∼ 2 km over much of its length. For later evolution of the trail, see Extended Data Figs 8 and 9 .

Extended Data Figure 8 Evolution of the lower part of the dust trail as seen from Chelyabinsk during the first minute.

Three frames from video 6 (the video has colour defects). The time is given in minutes and seconds and is counted from 3:20:20  ut . The lower marks identify points on the trajectory in 1-km altitude intervals. The upper marks identify points at the same geographic coordinates but 1 km higher. The video demonstrates vertical ascent and splitting of the trail. When the original video is speeded up, rotation of the material in the trail is clearly visible. The trail was illuminated from below. The ‘bubble’ formed at the position of the main hotspot (HS1; see Extended Data Fig. 7 ) was in shadow most of the time. Only its illuminated top is visible on the third frame, just at the edge of the field of view.

Extended Data Figure 9 Longer-term evolution of the dust trail.

Five frames from an uncalibrated video ( http://www.youtube.com/watch?v=Z20lnOVscpc , author D. Beletsky) taken from south of the fireball trajectory (on the road from Magnitogorsk to Chelyabinsk). The time is given in minutes and seconds and is counted from 3:20:20  ut . The trail was fully illuminated from this site. The video demonstrates the rise of the ‘bubble’ formed at the position of the main hotspot (HS1; see Extended Data Fig. 7 ). The maximum altitude was reached about 3 min after the bolide had passed by.
