The Concepcion volcano is located on the Ometepe Island in the Lake of Nicaragua.
The island is made of 2 volcanoes: Concepcion and Maderas.
This volcano has been the subject of a course on "Volcanic Risks Mapping Using GIS" held in Sep. 95 at INETER,
and taught by Carlos MUNOZ. (43 / 47 / 28 / 34 / 57 Kb) Pictures: Sep. 95
From left to right: Dec. 6, 95 explosion, lateral lava flow, field of ash at the foot of the volcano,
a crazy perspective on the flank of the volcano (Markus Kesseler gives the scale).
Last two pictures: ash deposit on the cathedral at Leon, 20Km away!!!
Good to know: A volcano doesn't have to be tall and big
to be dangerous.
Too often people just forget that..
The Masaya volcano, located SE of Managua, is also a national park.
The structure shows 2 craters, one active, the other one dormant. It is possible to see the previous fossilized lava lake levels (pictures 2 to 7).
The volcano has continuous gas emissions and seismic activity.
It is monitored by the INETER (National Nicaraguan Institute for Territorial Studies) in Managua.
The seismic volcano monitoring is done thanks to the collaboration between them and the Swiss Disaster Relief Unit.
