Lake Coatepeque, a volcanic crater lake in western El Salvador formed between 72,000 and 51,000 years ago, has become the subject of intensifying scientific scrutiny — from NASA astronaut photography and geochemistry studies to the discovery of rare cyanobacteria blooms and a $6.7 million government restoration project deploying ultrasonic buoys. The convergence of volcanology, limnology, and environmental engineering at this single site represents a case study in how developing nations are leveraging technology to rescue threatened freshwater ecosystems.
