Where on Earth? - April 2016

Where on Earth - April 2016

Clues for April 2016:

1. This 85-square-kilometer lake stretches to the northwest of one of Earth’s most active volcanoes, a 1,670-meter-tall andesitic stratovolcano that began forming about 7,000 years ago and most recently erupted in an episode lasting from 1968 to 2010.

2. The volcano, part of a subduction zone-formed arc, is located in the north of a tropical isthmus nation renowned for its ecotourism. This lake in particular is a popular spot year-round for windsurfing and fishing.

3. A 157-megawatt hydroelectric dam built in 1979 raised the lake’s surface by more than 40 meters, forcing nearby villages to relocate. Today, the dam provides roughly 10 percent of its home country’s electricity.
