The 2008 Moon Base Blox Earthquake was a 10.3 magnitude earthquake or “moonquake” that struck in Moon Base Blox, a moon research base that doubles as a college for Robloxians, on October 31, 2008. Despite it being powerful to trigger tsunamis, the moon has no liquid water, therefore tsunamis were impossible. However, two to five tunnels in Moon Base Blox collapsed are being deprived of oxygen, causing a Moon Base Blox mine to collapse underground. Sinkholes would be so deep that entire buildings in the Moon Base Blox area would be sucked into the core of the planet. The deepest known sinkhole was the Toko Trench, at about 600 feet (0.18 km) deep. Hundreds of Robloxians were killed and injured initially, and around 45,000 Robloxians were killed and 7,300 Robloxians were injured by the earthquake's aftermath. It took many Robloxians by surprise because earthquakes have not said to occur on the moon. Only a very small portion of Robloxians managed to evacuate to Roblox injured, and a minuscule portion of Robloxians managed to evacuate to Roblox uninjured.
This disaster would prove to be the deadliest disaster that occurred outside of Roblox and the fifth-deadliest disaster that occurred inside or outside of Roblox.
Pre-earthquake
The first earthquake recorded in the Moon was recorded in Moon Base Blox in 2006. It was a tremor that the base, with a magnitude of 6.1. At first, no speculation went into this, as earthquakes has not said to occur on the moon.
Moon Base Blox issued an extra precaution warning for their base. Five to eight months before the earthquake, 8,000 more tremors ranging between 5.3 and 6.3 struck in the same area. The Roblox Moon Geological Survey (RMGS) put the area surrounding Moon Base Blox in "High" risk of a major earthquake. Three months before the earthquake, a non-significant magnitude 6.1 earthquake struck. Unfortunately, six Robloxians were injured. Two months before the earthquake, a 7.1 magnitude earthquake impacted. The month before the earthquake, the area was quiet for the third time until 12 days before the earthquake, when a magnitude 8.0 earthquake impacted.
On October 31, 2008, 2:30 PM, Moon Base Blox geologists found that a mega quake is due to occur on their moon base.
During Earthquake
At October 31, 2008, 11:38 PM, the 10.3 magnitude earthquake struck violently for 30 seconds.
Post-earthquake
One minute after the earthquake, a message has been sent out as an alert. The alert said, "The site is experiencing multiple C-2/C-3 containment breaches, full site lockdown initiated.". Robloxians at the mines heard dark laughter and faint screaming.
Three minutes after the earthquake, the alert has been upgraded to a warning. The warning said, "All Level 4 personnel and above, please note. Several personnel have gone missing in the Containment Hall. Investigate the area when you can. Some "characters" have breached. Reinforcements from the government known as ■■■■■■■■ will enter to handle the situation. All personnel Level 3 personnel or below are to evacuate the premises immediately, to the nearest rocket back to Roblox."
This tremor followed by almost 278,000 aftershocks, with the second strongest, an 8.7 magnitude tremor, occurring a day after the main shock. 17% were over magnitude 6, 29% were over magnitude 5, and the rest below 5. This earthquake, due to the extensive nature of it, also caused other, more local earthquakes, such as a series of 5.8 to 6.5 earthquakes east of the base. Since the moon has no atmosphere, no fires broke out near the base. A 9.1 magnitude tremor occurred soon after. Most of the aftershocks over magnitude 5.1 were between 7.6 to 9.6.
In 2016, an expedition to Moon Base Blox to investigate the pristine ruins of Moon Base Blox was cancelled.
As of May 28, 2021. RSA and RSCP rovers and ships have landed on Moon Base Blox are currently investigating the pristine ruins of the base.
Post-Analysis
The earthquake has been initially categorized as a Magnitude 10.0 earthquake. As of September 27, 2021, 10:40:59 AM, close analysis found out that the earthquake was actually a Magnitude 10.3 earthquake.
Legacy
On October 31, 2021, at 2:30 PM, to celebrate the 13th anniversary of the 2008 Moon Base Blox Earthquake, a memorial will be held, and a statue will be erected in Downtown Brookhaven.
