QUITO - Ecuador's National Geophysical Agency said on Tuesday the Tungurahua volcano had registered 50 explosions in the past 24 hours.

The Tungurahua volcano, one of the most active volcanoes in Ecuador, started its second activity peak this May since the eruption process began in August 1999.

It is now experiencing "shivers": constant tremors inside the crater's bed. The agency's volcanologists have observed constant emissions of gas, ash and water vapor that is forming a cloud around 1 km above the volcano's crater.
