1957 Farsinaj earthquake

A dawn of dust and quiet: what the first morning looked like in Farsinaj

It began like other hard winters in the Zagros — low overcast skies, a chill in the air, donkeys tethered near house walls, smoke from small fires curling from chimneys. Then the earth moved, not gradually but in a violent, uncompromising instant. Villagers tell similar stories for many earthquakes: a roar or a low groan, a floor that feels liquid, roofs that shed brick and timber as if a hand had knocked them loose. In the narrow dirt lanes of Farsinaj and its neighboring hamlets, doorways were blocked by fallen lintels, storerooms were crushed, and the familiar geometry of courtyards became an obstacle course of rubble.

Neighbors rushed out. Some of the men and women who had slept through the first tremor woke to the second, smaller shocks that followed; those aftershocks kept people out in the open, wrapped in blankets or standing in the cold, counting the breaths between shakes. In many places — where houses were adobe or unreinforced masonry — walls had split cleanly down the middle. Roof timbers lay in modest piles. A goat or a donkey stood tied near a broken wall, unharmed, its presence a quiet reminder of livelihood that for many families had just been jeopardized.

How these hills were always building toward a break

Western Iran sits where two great plates meet: Arabia pushing north against Eurasia. That slow, relentless squeeze is written into the landscape of the Zagros — a belt of folded and faulted mountains that have been rising for millions of years. Each fold and thrust is a scar of this tectonic argument; each fault is a seam that sometimes slips.

By the 1950s that geological pressure had long translated into human vulnerability. Towns and villages in Harsin County and across Kermanshah Province were largely rural, their houses built from local stone, sun-dried brick, and adobe with timber roofs. Those materials were affordable and suited to the climate and local skills, but they offered little resistance to strong shaking. Roads were simple dirt tracks. Communications were patchy. Seismology in Iran was still developing; regional networks were sparse. When an earthquake struck, nearby towns depended on neighborly help, the provincial administration, and whatever medical care could be mustered and transported across difficult terrain.

That vulnerability — structural, infrastructural, institutional — formed the backdrop to the disaster that unfolded on December 13, 1957.

The pulse of the shock: seconds that changed villages

Contemporary reports record the main shock on December 13, 1957. Instrumental catalogs assembled later place the event in the western Zagros fold-and-thrust belt near Farsinaj, in Harsin County of Kermanshah Province. The precise epicenter and magnitude reported in various catalogs show modest differences — a common feature of mid‑20th‑century earthquakes recorded by limited networks — but every account agrees on the human result: many houses collapsed or were damaged beyond safe use; storerooms, animal shelters, and other ancillary buildings were badly affected.

In many villages, collapse was partial rather than total: an exterior wall might fall away, leaving a pocket of trapped family members; across a courtyard a single beam could hold just enough of a roof to prevent a full roof fall, but the structure that remained was no longer livable. The first hours were a scramble. Those not injured moved to clear rubble, dig people out with hands and ropes, or improvise simple shelters from the remains of timber and fabric. Where physicians or medical supplies existed, they were shared; serious injuries were transported by whatever vehicle could be found — an agricultural truck, a cart, or by human shoulder — along the limited road networks to larger towns.

Chaos in the lanes and the aftershocks that wouldn't let people sleep

For survivors, one element made the destruction harder to bear: aftershocks. In the hours and days following the mainshock, small to moderate tremors continued to rattle already weakened structures. Each aftershock threatened the fragile piles of masonry and the makeshift tarps people crowded beneath. That uncertainty complicated rescue efforts: volunteers paused when a jolt came, then raced back when the ground calmed.

Local medical facilities — sparse by modern standards — stretched to meet the need. In many instances, care was informal: neighbors who had some training, traveling physicians who happened to be passing, or municipal workers who could stitch wounds and stop bleeding. Bodies were recovered and buried quickly, often in small, hurried ceremonies. Animals, when spared, became an essential source of continuity: a surviving donkey could still carry wood and water, and a living goat made a difference to a family short on food.

Provincial authorities organized convoys of relief supplies from larger towns and the provincial capital. Bread, blankets, and basic medical kits were conveyed where roads allowed. But the scale of help was local and provincial; the disaster did not prompt a large, immediate international relief operation. That reality reflected the era — mid-20th‑century Iran had limited capacity and depended on regional administrative structures to respond.

Numbers that refuse a single figure

One practical frustration of studying this event is the numbers. Mid‑century reports — newspapers, provincial bulletins, and later seismological catalogs — offer figures that vary. Contemporary English-language summaries and some catalogs report that the human toll ran into the hundreds and perhaps into the low thousands when injured and killed are combined. Other accounts provide different totals. The most reliable modern studies of the region treat those figures cautiously, noting that casualty and damage tallies from 1950s provincial sources were not standardized and that records may be incomplete.

Property losses were large for the communities affected. Whole houses, storerooms of grain and seed, and animal shelters were damaged or destroyed. For subsistence farmers and pastoralists, those losses meant immediate disruption to food and income and prolonged hardship as winter set in. No comprehensive national-level dollar valuation from the period survives in widely accessible English-language sources; aftershocks, seasonal needs, and limited cash resources slowed reconstruction.

Winter, rubble, and the months when life was improvised

In the weeks and months after December 1957, life for many villagers became an exercise in improvisation. Damaged houses were left standing in ruin; others were patched in makeshift ways — wooden props holding weak walls upright, tarps for roofs, shared cooking fires in open courtyards. The coming winter made rapid rebuilding urgent and difficult. Provincial relief attempted to prioritize the most vulnerable: families without shelter, the injured, and households that had lost their food stores. But logistics — poor roads, bad weather, and limited materials — slowed the pace.

Reconstruction in remote villages was incremental. Where families could, they repaired rather than rebuilt, salvaging stones and bricks to shore up walls. Others migrated temporarily to larger towns or to relatives. Municipal officials documented damage as best they could, but without the modern frameworks for economic loss assessment and standardized reporting, many details remained local and anecdotal.

What the earthquake taught those who would study it

The 1957 Farsinaj shock did not, on its own, reshape national policy. But it contributed to a growing body of experience that Iranian engineers, administrators, and seismologists would draw on over subsequent decades. Repeated earthquakes across Iran in the second half of the 20th century — each with its own pattern of damage and recovery — gradually produced a more systematic understanding of vulnerability in traditional rural construction and the need for building practices better suited to seismic regions.

Seismologists compiling historical catalogs use the 1957 event as a data point in the Zagros seismic story. Later reanalyses place it among a set of mid‑century earthquakes that help define activity rates and strike-slip and thrusting behaviors in the fold-and-thrust belt. The exact coordinates and magnitude assigned to the shock vary among different catalogs, a predictable consequence of sparse instrumental coverage at the time; modern researchers accept that uncertainty and work with ranges rather than single definitive values.

The human record that remains incomplete

What persists most clearly are human memories and scars on the landscape. Villages rebuilt, sometimes with the same materials and forms as before. Families who lost property continued to farm the same slopes. The social networks that had been a first line of response — neighbors, extended families, local religious and civic leaders — were reinforced by the experience.

At the same time, archival gaps remain. Precise casualty lists, full inventories of damaged settlements, and standardized economic-loss figures are often missing from accessible sources. Much of that detailed record exists, if at all, in Persian-language provincial reports, local newspapers from Kermanshah Province, and administrative records that were not always preserved or widely distributed. For historians and seismologists, those local papers and provincial archives are the best places to seek the fuller quantitative picture.

Why the 1957 Farsinaj earthquake still matters

This earthquake sits in a long sequence of shocks that have shaped both the physical terrain and the human communities of the Zagros. It is a reminder of how geological forces and traditional ways of life collide: the affordability and availability of adobe and unreinforced masonry made sense to generations, but in the face of strong shaking those choices amplified danger. The shock underlined a persistent lesson in earthquake-prone regions worldwide — that vulnerability is the product of geology and of human decisions about where and how to live.

For scholars, the event is a piece of the puzzle in reconstructing seismic histories and understanding regional deformation. For families and villages that lived through it, the earthquake is an episode of loss and endurance — buried, in some accounts, in numbers that never fully settle, but alive in the altered courses of lanes and in rebuilt walls that show where bricks were replaced and where they were not.

When a visitor today walks the low rolling foothills of the western Zagros and looks toward the tiny villages that dot the slopes, the landscape offers quiet testimony: a line of rebuilt houses, a wall propped at a jaunty angle, a donkey crossing a lane. Those everyday scenes are the afterimage of the December morning in 1957 when the ground moved and handed people, suddenly and without ceremony, the task of rebuilding lives from rubble.
