時々少しずつ震動する程度で、それから碓氷峠を江戸の方へ越えたところ、二十四日夜にかなりの地震があっただけで、その後は地震がないとのことでした。
以上は御用中の大変な出来事を見分した様子を大まかに書面の通りに記したものです。詳細な事については追々とその場所から取り調べて申し上げることと存じます。以上

信州高井・水内郡村々地震の件について再度の御届け
去る月の末日に御届け申し上げました私の御代官所当分御預かり所の信濃国高井・水内郡村々の件で、去る月二十四日夜の大地震異変の始末を御届け申し上げましたが、その後も震動が止まず、今でも震動しており、昼夜十四五度ほど少しの間ずつ震え立ち、もっとも時々は強いこともありますので、村々が恐怖し、後片付けはもちろん農業に気を向けることもなく、うろたえ騒いでおりますので、安心させるよう私並びに手附・手代どもが村々を巡回し、精々利害を申し聞かせ、耕作が遅れないよう取り計らっております。
また去る月二十七日、真田信濃守の家来から掛け合いがありましたのは、この地震によって北国往還丹波島村渡船場より凡そ二里半程川上の同人領分平林村地内字虚空蔵山凡そ二十町程のところで山抜け崩れが起こり、現在川上の平地へ水が開いて流れ込んでおりますが、湛水が溜まって切れると自然に押し埋められた切れた場所を水力で押し崩すでしょうから、その節はどのような洪水になるか心配で、支配所の千曲川縁の村々に心得置くよう申し

There were only occasional slight tremors, and when we crossed Usui Pass toward Edo, there was a considerable earthquake on the night of the 24th, but after that there were reportedly no earthquakes.
The above is a rough account as written of the major incidents witnessed during official duties. Details will be investigated and reported from those locations in due course. The above.

Second Report Regarding Earthquakes in Villages of Takai and Minochi Counties, Shinshū
Following up on my report submitted at the end of last month concerning the villages of Takai and Minochi counties in Shinano Province, which are currently under the temporary custody of my magistrate's office: after reporting the circumstances of the great earthquake disaster on the night of the 24th of last month, the tremors have not ceased and continue even now. There are tremors lasting brief periods fourteen to fifteen times day and night, and occasionally they are quite strong. The villages are in fear, and rather than cleaning up the aftermath or attending to agricultural work, they remain in panic and confusion. To calm them, I and my assistants and clerks have been making rounds of the villages, earnestly explaining the situation to them and taking measures to ensure that farming work does not fall behind.
Furthermore, on the 27th of last month, retainers of Sanada Shinano-no-kami came to confer about how this earthquake caused a mountain collapse at a location called Kokūzō-yama in Hirabayashi Village within his domain, approximately twenty chō in extent, located about two and a half ri upstream from the Tanbajima Village ferry crossing on the Hokukoku Highway. Water is currently flowing onto the upstream flatlands, but when the accumulated water breaks through, it will naturally wash away the blocked areas with water force, so there is concern about what kind of flooding might occur at that time. Word should be sent to villages along the Chikuma River in the administrative area to be prepared, they said.
