Today is the 108th Anniversary of The Great Quake

Just a coincidence or something more?

Today is the 108th Anniversary of The Great Quake which is considered as one of the most significant earthquakes of all time. At precisely 5:12 a.m. on April 18th, 1906 and caused damage to both life and property all over California. The city affected the most was San Francisco. Most of the town was destroyed by the quake and the fire caused due to it.

Today exactly 108 years later a series of quakes rocked the Illinois region.

As per wikipedia :-

The San Francisco earthquake of 1906 was a major earthquake that struck San Francisco and the coast of northern California at 5:12 A.M. on Wednesday, April 18, 1906. The most widely accepted estimate for the magnitude of the earthquake is a moment magnitude (Mw) of 7.8; however, other values have been proposed from 7.7 to as high as 8.3. The mainshock epicenter occurred offshore about 2 miles (3 km) from the city, near Mussel Rock. It ruptured along the San Andreas Fault both northward and southward for a total length of 296 miles (477 km). Shaking was felt from Oregon to Los Angeles, and inland as far as central Nevada. The earthquake and resulting fire is remembered as one of the worst natural disasters in the history of the United States. The death toll from the earthquake and resulting fire represents the greatest loss of life from a natural disaster in California’s history. The economic impact has been compared with the more recent Hurricane Katrina disaster.

From the USGS :-

The California earthquake of April 18, 1906 ranks as one of the most significant earthquakes of all time. Today, its importance comes more from the wealth of scientific knowledge derived from it than from its sheer size. Rupturing the northernmost 296 miles (477 kilometers) of the San Andreas fault from northwest of San Juan Bautista to the triple junction at Cape Mendocino, the earthquake confounded contemporary geologists with its large, horizontal displacements and great rupture length. Indeed, the significance of the fault and recognition of its large cumulative offset would not be fully appreciated until the advent of plate tectonics more than half a century later. Analysis of the 1906 displacements and strain in the surrounding crust led Reid (1910) to formulate his elastic-rebound theory of the earthquake source, which remains today the principal model of the earthquake cycle.
