Volcán de Agua (also known as Junajpú by Maya) is an extinct stratovolcano located in the departments of Sacatepéquez and Escuintla in Guatemala.

[1] Despite the lack of eruptive activity, the volcano can still produce debris flows and lahars that inundate nearby populated areas.

In 1895 Anne Cary Maudslay and her husband, archeologist Alfred Percival Maudslay visited the Antigua Guatemala region as part of a journey through Guatemala's Maya and colonial archeological monuments, and climbed the Volcán de Agua; she wrote a book called A Glimpse at Guatemala where she explains that water from the volcano crater could not have destroyed the old Santiago: The cause of this catastrophe is usually said to have been the bursting of the side of a lake which had been formed in the crater of the extinct Volcán de Agua; but an examination of the crater shows this explanation to be improbable, as the break in the crater-wall is in an opposite direction, and no water flowing from it could have reached the town.

Indeed, an accumulation of water during the exceptionally heavy rain, through some temporary obstruction in one of the deep worn gullies which indent the beautiful slope of that great mountain, and a subsequent landslip would probably account for the damage done without the aid of either an eruption of water from the crater or the supernatural appearances which are duly noted by the old chroniclers.

[11] On 21 January 2012, 12,000 Guatemalans formed a human chain all the way to the peak of Volcán de Agua in a protest against domestic violence.
