Why it is safe to visit a volcano that is well monitored

When visiting the volcano we often get the same question: is it safe? And why?
To help you understanding why visiting Taal volcano is not dangerous when the alert is below level 2, let’s check how the institute of volcanology monitors it.


There are several signs that are monitored:

- Seismicity: volcanic earthquakes and tremors are one of the main signs indicating that a volcano is about to erupt. Many of them are not felt but if their frequency increases it might be the sign of an eruption. Taal volcano has an average of 2 to 10 volcanic earthquakes at rest.

- Ground deformation: ground swelling or fissures indicating an intrusion of magma.

- Gas: emission of CO2 is also monitored. the volcano emits an average of 500 to 2000 tons a day at rest.

- Steam activity: in case of strong fumarolic activity the alert level could be increased.

- Temperature of water for crater lakes, hot springs. the volcano crater lake has an average temperature of 31 to 35 degrees Celsius. The acidity and the level of the water are also checked.

Thanks to a strict monitoring, eruptions can be predicted and as long as the alert level is below 2, it is safe to explore volcano island.

Tripinas always check the alert level of the volcano before organizing any trip.
