Cleveland East Ohio Gas Explosion occurred on the afternoon of Friday, October 20, 1944. The resulting gas leak, explosion and fires killed 130 people and destroyed a one square mile area on Cleveland, Ohio's east side.
At 2:30 p.m. on the afternoon on Friday, October 20, 1944, above ground storage tank number 4, holding liquefied natural gas in the East Ohio Gas Company's tank farm, began to emit a vapor that poured from a seam on the side of the tank. The tank was located near Lake Erie on East 61st Street, and winds from the lake pushed the vapor into a mixed use section of Cleveland, where it dropped into the sewer lines via the catch basins located in the street gutters.

As the gas mixture flowed and mixed with air and sewer gas, the mixture ignited. In the ensuing explosion, manhole covers launched skyward as jets of fire erupted from depths of the sewer lines. One manhole cover was found several miles east in the Cleveland neighborhood of Glenville.

At first it was thought that the disaster was contained, and spectators returned home thinking that the matter was being taken care of by the fire department. At 3:00 p.m., a second above-ground tank exploded, leveling the tank farm.

However, the explosions and fires continued to occur, trapping many who had returned to what they thought was the safety of their own homes. Housewives who were at home suddenly found their homes engulfed in flame as the explosion traveled through the sewers and up through drains. The following day, Associated Press wire stories contained quotes from survivors, many of whom were at home cleaning in preparation for the coming Sabbath. Survivors said that within a split second after the explosion, their homes and clothes were on fire.

Cuyahoga County Coroner Dr. Samuel Gerber estimated that the initial death toll stood at 200; however, Gerber was quoted in newspaper wire stories stating the magnitude of the fire and the intense temperatures had the power to vaporize human flesh and bone, making an exact count impossible until weeks after the disaster. The final death toll was lower than the coroner’s initial estimates.

The toll could have been significantly higher had the event occurred after local schools had let out and working parents returned to their homes for the evening. In all over 600 people were left homeless, and seventy homes, two factories, numerous cars and miles of underground infrastructure destroyed.

Following the explosions and fires, East Ohio Gas worked to assure the public that the destroyed plant only held 24 hours worth of gas for the city. Many families living in the area not only lost their homes, but stocks, bonds and cash, which many kept at home. Estimates for destroyed personal and industrial property ranged between $7,000,000 and $15,000,000.

The explosion also had a long range impact on the natural gas industry. Until the disaster, above ground storage of natural gas, used as fuel for homes, office buildings and factories, was a common sight in cities across America. Following the disaster, utility companies and communities began to rethink their natural gas storage systems, and below ground storage of natural gas grew in popularity.

The disaster plays a major role in Don Robertson's 1965 novel "The Greatest Thing Since Sliced Bread."

The EAST OHIO GAS CO. EXPLOSION AND FIRE took place on Friday, 20 Oct. 1944, when a tank containing liquid natural gas equivalent to 90 million cubic feet exploded, setting off the most disastrous fire in Cleveland's history. Homes and businesses were engulfed by a tidal wave of fire in more than 1 sq. mi. of Cleveland's east side, bounded by St. Clair Ave. NE, E. 55th St., E. 67th St., and the MEMORIAL SHOREWAY. At approx. 2:30 P.M., white vapor began leaking out of Storage Tank No. 4, which had been built by the East Ohio Gas Co. in 1942 to provide additional reserve gas for local war industries. The gas in the tank, located at the northern end of E. 61st St., became combustible when mixed with air and exploded at 2:40 P.M., followed by the explosion of a second tank about 20 minutes later. The fire spread through 20 blocks, engulfing rows of houses while missing others. The vaporizing gas also flowed along the curbs and gutters and into catch basins, through which it entered the underground sewers, exploding from time to time, ripping up pavement, damaging underground utility installations, and blowing out manhole covers. The immediate area surrounding the burning district was evacuated and refugees were sheltered in Willson Jr. High School on E. 55th St. where the Red Cross tried to care for approx. 680 homeless victims.

By late afternoon Saturday much of the fire had burned itself out, electricity was restored in some areas, and the next day a few residents began returning to their homes. The fire destroyed 79 homes, 2 factories, 217 cars, 7 trailers, and 1 tractor; the death toll reached 130. The fire and subsequent analysis of its cause led to new and safer methods for the low-temperature storage of natural gas.
