Arizona 5.2 Earthquake

Arizona: A shallow 5.2 earthquake occurred at 9:59 pm June 28, 2014 near the Southeast boundary of the Arizona State line as it borders New Mexico. Shallow earthquakes are typically felt over a larger area as compared to deep earthquakes.

The USGS generally identifies the largest, most well known city which is closest in proximity to the epicenter. In this case the epicenter is in Arizona, while the closest city is in New Mexico.

Hate to say this but one of the quiet things going on in New Mexico is an enormous fracking effort. East part of the state. No idea if near there.

New Mexico Earthquake History

Most of New Mexico's historical seismicity has been concentrated in the Rio Grande Valley between Socorro and Albuquerque. About half of the earthquakes of intensity VI or greater (Modified Mercalli intensity) that occurred in the State between 1868 and 1973 were centered in this region.

The earliest reported earthquake in New Mexico was an intensity V tremor that occurred near Socorro on April 20, 1855.

In the years that followed, Socorro was struck by numerous low to moderate intensity earthquakes. Most of these caused little or no damage and were felt over a small area.

However beginning on July 2, 1906 and lasting well into 1907, the area was affected by shocks almost daily. There were three fairly severe shocks in this series.

The first was an intensity VII tremor that struck on July 12, 1906 and cracked some adobe walls and threw others down. Ground fissures and visible waves on the surface were reported with this earthquake.

Another shock of intensity VII on July 16, 1906 was felt at Raton, about 370 km northeast of Socorro and at Douglas, Arizona, about 420 km southwest. The epicenter was probably about 16 km west of Socorro.

On November 15, 1906, an intensity VII shock was felt over an area of about 250,000 square kilometers.

Rumbling sounds were heard during this earthquake.

Largest Earthquake in New Mexico

This earthquake, which increased the property damage already sustained at Socorro, was described as the most severe shock of the year.

Four rebuilt chimneys were shaken off the Socorro County Courthouse, and two others were cracked severely. Plaster fell at the courthouse, and a cornice on the northwest corner of the two-story adobe Masonic Temple was thrown onto its first floor.

Several bricks fell from the front gable on one house. Plaster was shaken from walls in Santa Fe, about 200 kilometers from the epicenter. Felt over most of New Mexico and in parts of Arizona and Texas.

Later shocks occurred at Socorro on July 18, 1913 (intensity V), January 31, 1919 (intensity IV-V), and February 1, 1919 (intensity V).

An intensity V earthquake caused slight damage at Socorro on January 7, 1934.

The most recent shock to affect the area occurred on July 3, 1961, causing slight damage at Socorro (intensity VI).

The towns of Bernardo and La Joya, about 30 kilometers and 40 kilometers north of Socorro, have been the center of a number of moderately strong earthquakes.

On February 20, 1935, an intensity VI shock damaged adobe and concrete buildings at Bernardo. This earthquake was accompanied by a thunderous roar.

On July 22, 1960, an intensity V tremor knocked some items from shelves at La Joya.

The next day on July 23, 1960, a weak adobe wall was toppled and adobe buildings were cracked by an intensity VI earthquake. The total felt area of this shock was about 7,800 square kilometers.

One day later on July 24, 1960, an intensity V shock broke two small windows at Boys Ranch and awakened many persons at Bernardo.

Belen, about 56 kilometers south of Albuquerque, experienced a series of earthquakes that lasted from December 12 to 30, 1935.

Loud subterranean sounds accompanied a strong shock on December 17, that cracked the brick wall of an old public school buildings in Belen.

In addition, there were reports of fallen plaster and small objects shaken from shelves. Numerous weak intermittent tremors were felt in the area, with additional slight damage from tremors on December 19 and 21.

The area around Los Lunas was affected by a series of earthquakes in 1893 that lasted for about 3 months.

On September 7, 1893, five strong shocks, the most severe of intensity VII, struck Los Lunas. Many adobe buildings which had been weakened by earlier disturbances were thrown down.

Felt reports were also received from Sabainal.

Albuquerque has been the center of several moderately strong shocks.

On July 12, 1893, three intensity V earthquakes shook every house in the city. Clocks stopped, and one report told of a chandelier swinging for 10 minutes.

On December 3, 1930, two distinct shocks cracked plaster and dishes.

A strong localized shock of intensity VI on February 4, 1931, caused people to leave houses and created a near panic situation in theaters. Many people reported they were thrown from bed. Some building damage and landslides occurred.

On November 6, 1947, Zamora, slightly east of Albuquerque, was shaken by an earthquake. Cracks were reported in plaster and a fireplace.

Minor plaster cracks in a bank building in Albuquerque were reported from an intensity V earthquake on November 3, 1954.

The shock was also felt at Bernalillo, Sandoval, and Sandia Pueblo.

A lighter shock on November 2 was felt over the same area.

An earthquake, measured at 3.8, on November 28, 1970, awakened thousands at Albuquerque.

The shock had a felt area of 3,000 square kilometers. The roof of a barn collapsed and a rooftop air-conditioner shook loose and fell through a skylight. Plaster cracks, broken windows, and many other instances of minor damage were reported. Many burglar alarms were activated.

On January 4, 1971, another shock caused considerable minor damage in Albuquerque, principally at the University of Albuquerque.

An earthquake with strong local effects occurred on May 18, 1918, in Santa Fe County. At Cerrillos, people were thrown off their feet, a break in the earth's surface was noted, and fallen plaster was reported (intensity VII - VIII).

Similar effects were noted at Stanley.

On January 22, 1966, a magnitude 5.5 earthquake centered near Dulce affected about 39,000 square kilometers of northwestern New Mexico and southwestern Colorado.

Nearly every building in Dulce was damaged to some degree; many buildings had exterior and interior damage and considerable chimney damage was noted.

The principal property damage was sustained at the Bureau of Indian Affairs School and Dormitory Complex and at the Dulce Independent Schools.

Rockfalls and landslides occurred along Highway 17, about 15 to 25 km west of Dulce; in addition some minor cracks appeared in the highway.

Minor damage was also reported at Lumberton, NM, and Edith, Colorado.

A magnitude 4.1 shock on December 24, 1973, occurred near Grants. The tremor caused minor damage in the Grants area and was also felt at Laguna, Bluewater, and Fort Wingate. Maximum reported intensity was V.

Three miles is pretty shallow for there.

Thanks for the ping!
