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.
The republic of San Salvador was again visited by a great earthquake in October, 1878. Many towns, such as Incuapa, Guadeloupe, and Santiago de Marie, were almost totally destroyed, and many lives were lost. The shock causing the most damage had at first a kind of oscillatory movement lasting over forty seconds and ending in a general upheaval of the earth; the result being that solid walls, arches, and strongly braced roofs, were broken and severed like pipe-stems. In the vicinity of Incuapa a number of villages disappeared entirely.
The mountainous region of Mexico is highly volcanic, and earthquakes are of frequent occurrence. Very few of them, however, in the historic period, have occasioned great loss of either life or property. One of the most disastrous occurred in January, 1835, when the town of Acapulco was totally destroyed. In April, ten years later, the City of Mexico was much shaken. Considerable damage was done to buildings, especially to churches and other edifices of large size, several of which were reduced to ruins. The loss of life was limited to less than twenty. Probably the most serious convulsion the country has experienced was in 1858, when shocks were felt over almost all the republic, causing many deaths, and destroying much property. Over 100 people lost their lives on May 11 and 12, 1870, when the city of Oaxaca was visited by a succession of severe shocks, which tore down many buildings. Since this time Mexico has been free from convulsions of any great magnitude, although slight earth tremors are of frequent occurrence in different parts of the country.
Mexican volcanoes, likewise, are famous for their size, though of late years no great eruptions have occurred. There are many isolated peaks, all of volcanic origin, of which Orizaba, with a height of 18,314 feet, and Popocatepetl, 17,300 feet, the most renowned, are both active. The latter has one crater 5,000 feet in diameter. From the summit the Pacific Ocean and the Gulf of Mexico are both visible.
This crater has not erupted for many years, but in former times it threw its ashes a distance of sixty miles. One can descend into its depths fully 1,000 feet, and view its sulphur walls, hung with stalactites of ice, or see its columns of vapor spouting here and there through crevices that extend down into the interior of the earth. In the ancient Aztec and Toltec mythology of Mexico, this was the Hell of Masaya.
Nowadays great sulphur mines on the peak bring profit to the owners, and ice is quarried from the same vicinity to supply the neighboring city of Puebla.
