This image shows one of the most significant volcanic explosions ever seen from space. This is the Hunga Tonga volcano in the small island nation of Tonga in the Western Pacific. Check out these links: Video of tsunami coming ashore in Tonga…enormous and far-reaching shock wave of the explosion seen from space…the explosion caused one island to sink and another to form…wider view of the eruption and shock wave…black as night in Tonga under the ash cloud – ash is falling like snow. Major volcanoes of Tonga. Colored satellite loop. Air pressure surges across New Zealand. Another satellite loop of the explosion.
This was issued by New Zealand Civil Defense: “We have issued a NATIONAL ADVISORY: TSUNAMI ACTIVITY following the Tongan eruption. We expect New Zealand coastal areas on the north and east coast of the North Island and the Chatham Islands to experience strong and unusual currents and unpredictable surges at the shore.”
The eruption was accompanied by a strong earthquake, magnitude 7.6. “We’re hearing it in Tauranga, New Zealand! 2200 km (or 1300 miles for US folk) away. Unbelievable! Booming sounds and tremors felt in Figi.
The pressure wave came through Michigan (traveled around the world). You wouldn’t notice this, but more sensitive instruments can pick up these waves. Tsunami at Santa Cruz CA.
A major volcanic eruption can change the weather. After the gigantic explosion of Mount Tambora in 1815, we had the “year without a summer” in 1816. There was a noticeable cooling of the earth from the eruption of Mt Pinatubo in the Philippines in 1991. Water draining out of Ventura CA harbor.
