An ash plume rises above the crater lake of Poás volcano in 1915.  Intermittent eruptions producing some ashfall had begun October 8, 1914, and were continuing on May 15, 1915.  The April 10 eruption was seen from San José, and the last of a series of eruptions during April 15-19 produced ashfall at great distances.  Photo by R.
