every reason to believe to be correct, regarding the destructive earthquakes which have occurred. From this I gather that the country is becoming more and more liable to them and that they have steadily increased in number during the last few centuries. Thus there was but one destructive earthquake in the 5th century, which happened in the year 415; none other is known to have occurred till the 10th century; one more occurred in the 11th century, another in the 13th, 2 in the 16th, 10 in the 17th, 13 in the 18th and 15 in what has already passed of the 19th century. The average of this century therefore has been one destructive earthquake in every 5 years, while 300 years ago there was but one in 50 years. The following is a list of the most destructive which have occurred throughout the country.
In the 15th year of the reign of the 20th Emperor—in the year 415.—a destructive earthquake happened.
