Next, earthquakes are utterly uncertain as to time. No one knows when they are coming. They give no warning. Even in those unhappy countries in which they are most common there may not be a shock for months or years; and then a sudden shock may hurl down whole towns. Or there may be many, thirty or forty a-day for weeks, as there happened in a part of South America a few years ago, when day after day, week after week, terrible shocks went on with a perpetual underground roar, as if brass and iron were crashing and clanging under the feet, till the people were half mad with the continual noise and continual anxiety, expecting every moment one shock, stronger than the rest, to swallow them up. It is impossible, I say, to calculate when they will come. They are altogether in the hand of God,—His messengers, whose time and place He alone knows, and He alone directs. Our having had one last week is no reason for our not having another this week, or any day this week; and no reason, happily, against our having no more for one hundred years. It is in God’s hands, and in God’s hands we must leave it. All we can say is, that when one comes, it is likely to be least severe in this part of England, and most severe (like this last) in the coal and iron districts of the west and north-west, where it is easy to see that earthquakes were once common, by the cracks, twists and settlements in the rocks, and the lava streams, poured out from fiery vents (probably under water) which pierce the rocks in many places. Beyond that we know nothing, and can only say,—It is of the Lord’s mercies that we are not consumed. Why do I say these things? To frighten you? No, but to warn you. When you say to yourselves,—Earthquakes are so uncommon and so harmless in England that there is no need to think of them, you say on the whole what is true. It has been, as yet, God’s will that earthquakes should be uncommon and slight in England; and therefore we have a reasonable ground of belief that such will be His will for the future. Certainly He does not wish us to fold our hands, and say, there is no use in building or improving the country, if an earthquake may come and destroy it at any moment. If there be an evil which man can neither prevent or foresee, then, if he be a wise man, he will go on as if that evil would never happen. We ever must work on in hope and in faith in God’s goodness, without tormenting and weakening ourselves by fears about what may happen. But when God gives to a whole country a distinct and solemn warning, especially after giving that country an enormous bounty in an abundant harvest, He surely means that country to take the warning. And, if I dare so judge, He means us perhaps to think of the earthquake, and somewhat in this way.
