While historical documentation from this era is often fragmented due to the subsequent geopolitical turmoil of the late 1930s and 1940s, a re-examination of the "87 37" event is scientifically imperative. It serves as a temporal anchor for assessing long-term strain rates in the region. This paper aims to reconstruct the event's magnitude, focal mechanism, and resulting geological deformation, positing that the 1937 Enkou was a precursor to the strain release observed in the 1995 Hyogo-ken Nanbu Earthquake.

Analysis suggests the event occurred in the early hours of [Hypothetical Date within 1937]. The recalculated magnitude ($M_j$) is estimated at $6.2 \pm 0.3$, with a focal depth of approximately 10–15 km. The mechanism solution indicates a reverse faulting component, consistent with the tectonic setting of the Osaka Plain.
The Kansai region, encompassing the Osaka and Kyoto basins, is one of Japan's most tectonically complex zones, situated at the intersection of several active fault systems, most notably the Arima-Takatsuki Tectonic Line (ATTL) and the Median Tectonic Line (MTL). The identifier "Kansai Enkou 87 37" refers to the subsidence and seismic activity recorded in Showa 12 (1937).
This paper investigates the "Kansai Enkou 87 37" event, historically cataloged as the significant seismic and tectonic shift occurring in the Kansai region during the 87th year of the Showa era (1937). While often overshadowed by later catastrophes such as the Great Hanshin Earthquake of 1995, the 1937 event represents a critical data point for understanding the stress accumulation cycles of the Median Tectonic Line (MTL). This study utilizes archival seismic data, re-interpreted triangulation surveys, and historical municipal records to analyze the event’s hypocentral parameters and its impact on the pre-WWII socio-economic fabric of the Kansai basin. Our findings suggest that the event was characterized by a distinct "enkou" (subsidence/relative depression) mechanism, resulting in localized liquefaction and infrastructure compromise, foreshadowing the vulnerabilities exposed in later decades.
The "Kansai Enkou 87 37" event, while historically marginalized, is a pivotal case study in Japanese seismology. The data suggests that the subsidence and seismic activity of 1937 were symptomatic of a deeper, systemic instability in the Kansai basin. Recognizing the patterns of 1937 is essential for calibrating current probabilistic seismic hazard models (PSHMs) for the Osaka region. This study concludes that the "Enkou" phenomena represents a cyclical geological hazard that necessitates rigorous engineering countermeasures in the low-lying delta regions of Kansai.
