In Central America disasters of this kind invariably cause many of the inhabitants to emigrate. Men, women, and children form themselves into groups, and travel through the country. They set the drama in which they have taken part to music, and they journey from one village to another, singing the rude verses they have composed, and then sending the hat around. After they have visited the whole of their own country, they cross into the neighboring state, where they are also assured of a profitable tour. Thus for more than a year Honduras and Nicaragua were visited by bands of homeless victims, chanting in monotone the eruption of Lake Criba and the terrible catastrophe of San Jose. The western half of Nicaragua, including the basin in which lie Lakes Managua and Nicaragua, is a volcanic center, including some of the largest of the twenty-five active cones and craters of Central America. Stretching from northwest to southeast, the string of craters beginning with Coseguina and Viejo reaches well into the lake basin. At the northern end of Lake Managua stands Momotombo, while from the lake itself rises Momotombito. On the northwestern shore of Lake Nicaragua lies the volcano Mombocho, while between the two lakes is the volcano Masaya. Near the center of Lake Nicaragua are the two volcanoes of Madera and Omotepe. Since 1835 there have been six eruptions in Nicaragua, one of them, in 1883, being an outbreak in the crater of Omotepe in Lake Nicaragua, the route of the proposed Nicaraguan canal. The Coseguina eruption, the uproar of which was heard more than 1,000 miles away, threw the headland upon which it stands 787 feet out into the sea, and rained ashes and pumice-stone over an area estimated at 1,200,000 square miles. Like all Spanish towns in America, San Salvador, capital of the republic of that name, covers a large area in proportion to its population. The houses are low, none of them having more than one story, while the walls are very thick in order to be capable of resisting earthquakes. Inside each house of the better class is a courtyard, planted with trees, generally having a fountain in the center. It was to these spacious courtyards that, in 1854, many of the inhabitants of San Salvador owed their lives, as they found in them a refuge from their falling houses. On the night of April 16, the city was reduced to a heap of ruins, only a single public building and very few private ones having been left standing. Nearly 5,000 of the inhabitants were buried in the ruins. There was a premonitory shock before the great one, and many took heed of its warning and escaped to places of safety, otherwise the loss of life would have been even more terrible. Guatemala was visited with a series of almost daily tremors from the middle of April to the middle of June, 1870. The most severe shock was on the 12th of June and was sufficiently powerful to overthrow many buildings.
