Scientists have raised the threat level of an active super-volcano that holds the record for the biggest eruption on Earth in the last 5,000 years.
Taupō, in New Zealand, has not erupted for almost 1,800 years but scientists recently detected a change in its activity, the Daily Star reports.
The colossal volcano's alert level has been heightened from 0 to 1 in out of six, for the first time since the measuring scale system was established in 1994. The alert was raised by Geological agency GeoNet, after scientists discovered that a sequence of 700 mini earthquakes had occurred, although they were so insignificant, the majority were not felt on land.
