Tonga has another volcanic eruption, erupted eight times in two days but

Many friends should still be impressed by the January 15 eruption of the volcano in Tonga (specifically, the volcano in Tongan Hong Aha Apia), it is the world's largest eruption phenomenon in recent decades, and the level of the rare VIE-6 level, spewing lava ash and other materials up to 16 cubic kilometers (16 billion cubic meters), the column of ash smoke so high that you can not see the top, the sound of the explosion reached more than 1 More than 10,000 kilometers away, the resulting shock wave around the Earth ran four times and caused a sonic tsunami sweeping the entire Pacific Ocean, its power is comparable to the effect of thousands of Hiroshima atomic bomb explosion, resulting in the entire country of Tonga was once lost in the world, it is no exaggeration to say that its eruption let all mankind a deep appreciation of the majestic power from nature. It is no exaggeration to say that its eruption has made all mankind appreciate the majestic power of nature.

However, according to the China News Network on September 20, another Tongan volcano erupted. According to news from the Tonga Geological Service, a submarine volcano north of Tonga's main island began erupting on September 9 this year and has been erupting for 12 days so far, including eight eruptions in two days on the 18th and 19th, but the eruptions are not large, the lava material ejected from the eruptive vent continues to accumulate and continue island-building activities, and as of September 21, the eruption has created an area of Nearly 1-hectare island, the highest place more than 10 meters, but the eruption is continuing, the area of the island is also continuing to grow.

This is not the same volcano that erupted on January 15 this year in Tonga Hong Chapati, and the two are quite far apart, about 180 kilometres away. The location of the erupting volcano is near Tonga's Home reef, and its eruption will transform it from a reef to an island.

So why is there another volcanic eruption on a Tongan island? Even the main island of Tonga was formed by a volcanic eruption in ancient times, so it is not unusual to see volcanic eruptions in this area, and after the big eruption of the volcano in Tonga on January 15 this year, the geological activity here has been relatively active, and another eruption is also a normal phenomenon.

However, its eruption also reflects the global geological activity is tending to an active period, we all know that after entering September many places in the world after the occurrence of large earthquakes, first on September 5, China's Sichuan During an earthquake of 6.8 magnitudes, followed by Indonesia on September 10 and 11, three earthquakes of more than 6 magnitudes, at 7:46 a.m. on September 11, the island of New Guinea A 7.6 magnitude earthquake occurred in northeastern Papua New Guinea, a 6.9 magnitude earthquake occurred in Alien County, Taiwan Province, China at 2:44 p.m. on September 18, and a 7.7 magnitude earthquake occurred in Michigan State, western Mexico, at 2 a.m. on September 20, the largest magnitude earthquake of the year so far.

The frequent large earthquakes indicate that the collision between the Indian Ocean plate, the Pacific plate, and the Asian and European plates are becoming more intense, and the energy accumulation inside the earth's strata has reached a certain limit, which has given rise to many large earthquakes and some volcanic activities since September.

The eruption of this new volcano in Tonga also shows that since September, not only have the earthquakes suddenly become more, but volcanic activity is also more, what is happening to the earth? It's as if the internal activity has suddenly entered an active phase, which is not good for human society! So will the volcanic eruption in Tonga become bigger? Volcanic eruptions are as unpredictable as earthquakes, and humans are still unable to effectively grasp the lava and plate activity inside the Earth, so anything is possible. Now Tonga has raised the local volcanic eruption alert to an orange warning, warning people of the impact of a large eruption.

The Jan. 15 eruption of Tonga's Ahab Apia volcano was preceded by several small eruptions over many days, and the erupted material connected two small islands in the crater to form a much larger island. The height of 58 km high.

When the volcano erupted this year, some experts said that it would affect the climate and might even lead to a "summer less year" on earth, but this year the northern hemisphere of the earth is unusually hot, so this argument is considered unjustified, but in fact, the volcano is located in the southern hemisphere, it mainly affects the climate of the southern hemisphere The climate, and indeed in a very substantial reduction in atmospheric temperature in the same latitude of the volcano, satellite monitoring data show that in July this year, the southern hemisphere stratosphere dishpan level there was a wide range of anomalous cold, mainly concentrated in the southern hemisphere mid-latitudes, and nearly 40 years in the region at the same height in July compared to the average temperature decreased by 11 degrees Celsius, which shows. Volcanic eruptions are indeed causing a drop in atmospheric temperatures.

So why did not appear as experts say "no summer year"? The main or this volcanic eruption appeared in the sea, sprayed 16 cubic kilometres of material mostly released into the sea, and the material ejected from the sea floor, not easy to form floating in the air soot, so sent into the atmosphere of the volcanic ash is not much, if tens of billions of tons of volcanic ash released in the atmosphere, then this year at least the temperature of the southern hemisphere will drop steeply, so the large-scale volcanic eruptions are very scary. There have been many major volcanic eruptions in the history of the planet that have caused global extinction events, and scientists still need to do more research in this area.

Compared to Tonga erupting this volcano, a volcano in New Zealand is relatively more dangerous, according to the latest statement of the New Zealand Institute of Geological and Nuclear Sciences, the recent frequent earthquakes in the Lake Taupe region of New Zealand, from May since the small-scale earthquakes have not stopped, from January to September is more than 700 earthquakes, all signs show that it is likely to occur a larger eruption, will now Lake Taupe volcano eruption warning level from "zero" to a level.

Lake Taupe is New Zealand's largest freshwater lake, but its geology is actually a large caldera, which means there is a super volcano underneath, and 26,500 years ago there was a major eruption of VIE-8, which is about 100 times the size of this year's eruption in Tonga, and is the closest VIE-8 eruption on Earth today, and 1800 years ago it also had a VIE-7 eruption that almost destroyed New Zealand's North Island. However, this lake is now scenic and the surrounding area is currently inhabited by many people, so it is more dangerous, and even a VIE-6 eruption would hit New Zealand hard, while Tonga's latest eruption is surrounded by ocean, and a VIE-6 eruption would have less impact on humans.
