The 1692 Tortuga micrasquake and tsunami, (Sanpanese:黙示録) was a micrasquake and tsunami event. The first earthquake lasted 6 minutes at 09:41:02 local time CMT+4. The second earthquake lasted 41 seconds and the second had a magnitude of 7,0Mw. The number of deaths in the earthquake was barely 4000, but with the tsunami it reached up to 100 thousand deaths. The impact of the earthquake was felt intensely throughout the entire archipelago. Although the Kankaguro region was the least affected by the incident, it contained nearly a thousand dead. A tsunami measuring 130 feet hit all coastal areas. After the earthquake, Sanpantul's independence was compromised and ultimately ended. After this event, Sanpantul was divided into various shogunates, after which the region came under the rule of Batavia and the Beneluccas were re-established.

Background

The Minamo Trough lies in the deep subduction zone between the Tortuga Plate and the Captive Plate. The region lies on an active earthquake line due to seismic stress accumulated over centuries. The region is affected by such earthquakes quite frequently from time to time.

The first earthquake occurred at 09:44:02 local time (CMT+4) and lasted approximately 6 minutes. This main tremor had a magnitude of 9.1—the strongest recorded in the region's history. A second tremor followed at around 1:48 PM with a magnitude of 7.3 and lasted 41 seconds.

The succession of the two earthquakes caused a massive displacement of the seafloor, generating tsunami waves approximately 40 meters (130 feet) high. The waves reached Tortuga and surrounding coastal areas within 10–12 minutes. The tsunami destroyed all settlements north of Tortuga.

Damage and losses

The earthquake caused 100,000 casualties, with injuries reaching 500,000. Approximately 22% of the population of Tortuga lost their lives, and approximately 3 million people lived in Gencenia (the new Sanpanese territory). More than half of Gencenia's homes were either destroyed or severely damaged, leaving people struggling to find shelter. Tortuga harbor exploded due to damage to ammonium nitrate storage facilities, creating a third apocalypse. Minamo was also rendered unhabitable by its toxic air. Parts of the island were temporarily submerged, but the area returned to its previous state a year later. Cities such as New Kipei and New Miyaji were buried under heavy debris. Access to these areas was extremely difficult. Power lines were down, leaving many in the dark. Aid from Kankaguro District arrived late, but the region received sufficient aid without the need for international assistance.

Aftermath

Following the earthquake, authority in Sanpantul collapsed, and various shogunates emerged in Ganjania. The Tonugawa Shogunate was the most powerful shogunate in the region and was recognized as Sanpantul's spiritual successor. Before inter-society wars broke out in the region, the indigenous Beneluccas began to rebel against the Sanpo Shogunates, whom they called "invaders." Beneluccan forces quickly attacked the Shogunates as guerrillas, and subsequently, the Beneluccans became more organized. Beneluccan resistance fighters and pirates in the region deprived the Shogunates of trade access. The Batavian navy and army then intervened in the region.

After all of Gencenia/Beneluccas came under Batavia's control, the island of East Sandwich (the former Kankaguro district), where the Date Shogunate was located, began to attack the Batavian navy. The Batavian army invaded East Sandwich in mid-1693 AN, and the region was incorporated into the newly established Beneluccas. The local population, along with those who had migrated from Gencenia, accepted their fate.

There is a significant lack of sources regarding the Sanpo people of Sanpantul and what happened to the former Sanpantul during the Beneluccan period. The Sanpo population in the region has never been counted. However, the Batavian period profoundly altered the culture and social structure. The Tonugawa Dynasty resided in Phinbella for nine years, then returned to Sanpantul, which was re-established in 1702 AN when the region was transferred to Çakaristan.

The earthquake's significance persists in modern Sanpantul consciousness and remains a historical wound. The earthquake played a significant role in political motivations, and it has occasionally been used as a political tool by republican politicians.

The earthquake is commemorated annually on January 2nd as Mokushiroku Day, or "Shizukana no Hi," and life, except for the entertainment industry, continues as normal. The earthquake plays a significant role in the Sanpanese consciousness. The Mokushiroku Monument in Kipei is the largest monument dedicated to the earthquake. It has a wave-like shape and is composed of rectangular stones. The names of those who lost their lives are inscribed on the stones. The other major monument is the Ofu Earthquake Tower. The tower is approximately 44 meters tall. There is also an earthquake museum in Miyaji called the Earthquake Tumulus.

The event has frequently been depicted in Sanpanese literature, often under the theme of "society's drowning." The classic work, the Akitsushima Poems, describes the disaster as follows:

> "The sea offered us not the homeland, but the grave;

The sky was silent, only the water spoke."

Furthermore, the Sanpanese Earthquake Regulations were enacted in 1702 AN. Accordingly, inspections for house construction were increased, concrete quality was improved, and durability tests were introduced. Rail systems or bored piles were mandated for structures such as government institutions and apartment buildings.
