The 1946 Bloxport Earthquake was a devastating and widely felt earthquake with an epicenter along the southern section of the Western Robloxian Fault that occurred at an unknown time and date, but it was known to be a foreshock of the 1946 Roblox City Earthquake. Shaking had been felt as far north as Roregon and as far east as Barizona because of the widespread area of the rupture. The earthquake had an unregistered moment magnitude, but estimates say it was 8.1 +/- 0.1 with maximum seismic intensity of X (Extreme) on the Modified Mercalli Scale. A fault rupture was responsible for this.
Widespread damage had occurred, specifically in metropolitan areas where thousands of fatalities had occurred. Massive amounts of damage had occurred to areas like Bloxport, where violent shaking had been directed towards Blox Angeles. The majority of downtown Bloxport, along with Bloxport Beach, was split apart from the rest of Bloxport. Initially, the earthquake had killed 6,593-10,449 Robloxians in the span of minutes, according to the Robloxia Emergency Management Agency, but later on from the aftereffects of the earthquake, the death toll rose by 336.1%. The large amounts of death sparked a massive "Robloxianitarian" response in Roblox, with hundreds of billions of ROBUX donated. Following the earthquake, people had fled from Bloxifornia to the east, following the massive disruption to life and normality. Aftershocks had continued for an estimated 3.733 to 5.917 years.
