How wide is the crater of Volcan Poas in Costa Rica? How far is Volcan Arenal in Costa Rica from the Nicaraguan border?

rocky Oscar

Hi Oscar,

I can't seem to find a good map that shows me how wide the crater is, but I can tell you that Poas is about 50 km south of the Nicaraguan border. I just found a good enough map: Poas consists of an old, large caldera about 9 km NW-SE x 6 km NE-SW. Within this are two smaller collapses about 2 km across.

Sincerely,
Scott Rowland
