New Zealand: Tongariro volcano can be operated again

On July 20, New Zealand scientists officially warned of unrest and the risk of reactivation of Tongariro volcano in the center of the North Island after the volcano was shaken by a series of dynamic battles. small land.

New Zealand's GeoNet seismic watchdog upgraded the alert level around Mount Tongariro from level 0 to level 1, which means that the volcano has moved from dormant to signs of instability.

Small earthquakes that continued to occur under Mount Tongariro began on July 13, then fell rapidly, but re-started on July 18 and were stronger on July 19-20.

These dynamics are about 2.5 on the Richter scale, about 2-7km from Tongariro Crater.

GeoNet scientists have placed mobile seismographs around the earthquake epicenter, then took samples from hot springs, craters and gas spray holes in that area, to accurately assess more about the magnitude of the impact of earthquakes.

Seismic historical data shows that these small volcanic earthquakes were very popular in Tongariro, but usually only twice a year.

However, scientists have recorded more than 20 such earthquakes since July 13, suggesting that the risk of earthquakes causing volcanic activity is very likely.

Tongariro is a synthetic volcano consisting of craters and vents, formed from several cone-shaped volcanic peaks. This volcano erupted from 1855-1897, and could not determine its status during the period of 1926-1927.

On the same day, Defense Minister Chris Tremain warned New Zealand to take measures to deal with the danger from this nature.

In a national survey of disaster response, Chris Tremain said 88% of New Zealanders actually thought about and embarked on a preparation plan, while 55% said. They have thought of solutions to protect themselves and their families in the past 12 months.
