Because the soil around the volcano is very fertile, which is good for agriculture, and gradually developed into the current city, the city around the volcano generally has a long history.
-
Because after the eruption, there will be a lot of volcanic dust and volcanic ash distributed around, which is a good inorganic fertilizer, and there will be a lot of ore after the fire eruption, and there are some substances that are very medically valuable, so.
-
The land around the volcano is fertile, and most of the previous human civilizations were dominated by agriculture, so they chose to live in such a place, and then it became a city And then there was the social division of labor, and agriculture was not dominant, but the city was already established, and there were no major problems, and it was generally not abandoned It was said that it was because of low productivity and underdeveloped technology
-
Erupted volcanoes bring in mineral-rich ash, which helps crops grow, so villages are inhabited.
-
Both extinct and dormant volcanoes have not erupted in a long time, and the city was built with a view to making it suitable for settlement. Whether it was a volcano or not, how to understand it at the time.
-
It's like there are a lot of flies around the stool... Humans have access to food.
-
For humans. Dead and living mountains and dormant volcanoes are the same non-erupting volcanoes. Of course, these places can build cities.

The general classification of volcanoes can be divided into: 1Active volcanoes:
It is still active from time to time 2Dormant volcanoes: now inactive, but lack erosion changes 3
Extinct volcanoes have no record of activity in human history, and there are no signs of activity However, dormant volcanoes can awaken and extinct volcanoes can be resurrected, so it may not be correct to distinguish them based on past records alone. Generally speaking, volcanic activity is divided into three phases, of course, sometimes it does not necessarily occur in order, now let's take a look at these three phases: 1
An active volcano is a volcano that is erupting or has just erupted. Active volcanoes vary in their performance, from violent eruptions to slow eruptions. But don't be nervous, Taiwan's youngest active volcano, Guishan Island Volcano, was last active about 7,000 years ago, and the largest and most extensive eruption of the Datun volcanic complex ceased activity 200,000 years ago.
2.Dormant Volcano Dormancy means to sleep. Some volcanoes are not erupting now, but they are likely to erupt one day in the future, so these types of volcanoes are still very dangerous.
A dormant volcano may sleep for weeks, months, or even centuries before erupting suddenly. In general, the longer the volcano is napped, the louder it erupts. 3.
Extinct Volcano If a volcano no longer erupts, and it is no longer possible to erupt, we say that the volcano has entered the extinction phase and has become an extinct volcano. You may think that such a volcano is not dangerous, but in fact, although the volcano is dead, it may still be dangerous. For example, Tristan da Cunha, located in the South Atlantic Ocean, is a volcanic island that has been extinguished for many years.
However, one day in October 1961, the volcanic island of Tristan suddenly erupted, and the 280 residents of the island rushed to escape for their lives in small boats, which took two years before the residents dared to return home.

There are about 660 volcanoes in China, most of which are extinct volcanoes. Active volcanoes and dormant volcanoes are mainly distributed in Taiwan Province, Kunlun Mountains, Heilongjiang Province, Changbai Mountain, and Tengchong, Yunnan. There are more than 230 in Heilongjiang and Jilin, among which the famous ones are Wudalianchi and Baitou Mountain.
Inner Mongolia is the region with the largest number of volcanoes in China, with more than 270 volcanoes, and the largest volcanic group in China, including more than 100 volcanoes, is distributed here, of which the Dali volcanic group has as many as 56 volcanoes. Taiwan Province is located in the Pacific Rim Volcanic Belt, which is the place with the most volcanic activity in China. The Penghu Islands, Huojiao Island, and Diaoyu Islands are all volcanic islands formed by submarine volcanic eruptions.
Taiwan's most famous volcanic group, Datun Volcano, in the northern part of the island, consists of more than 10 volcanoes with an altitude of about 1,000 meters. Volcanoes in China are mainly found in the northeast to Inner Mongolia. Inner Mongolia is the region with the largest number of volcanoes in China, and now Taiwan is the most volcanic area in China.
China's volcanoes also have the characteristics of many "dead" and few "living".
-
The active volcano of Ashkule Volcano, the dormant volcano of Changbai Mountain, and the extinct volcano are innumerable.
-
This place has an article dedicated to volcanoes in China.
-
Our country's volcanoes are dead, at least for a long period of dormancy.
-
Changbai Mountain is an extinct volcano, typical. Just know this.
-
To put it simply: according to the activity of volcanoes, volcanoes can be divided into three types: active volcanoes, dormant volcanoes and extinct volcanoes.
1.An active volcano is defined as "a volcano that has been found to have erupted and been active in history", or "an active volcano";
2.A dormant volcano is defined as "a volcano that has erupted in the past and is now dormant", or "a volcano that has not erupted for a long time, but will erupt in the future";
3.An extinct volcano is defined as "a volcano that has not erupted at all in history" or "an inactive volcano".
-
An active volcano is a volcano that is active: the kind that can erupt at any time.
Dormant Volcano: It is a type of active volcano, but it is in a dormant period and does not erupt for a while, but it will regenerate for a certain period of time.
Extinct volcano: A volcano that will no longer erupt.
-
An extinct volcano has erupted before, but will not erupt again, an active volcano is still erupting, and a dormant volcano is in a dormant period, and there is a possibility that it will continue to erupt.
-
To sleep is to wake up and erupt, to die is to never erupt again, and to live is to erupt at any time ......The only remaining high school geographic memory.
-
Extinct volcanoes are unlikely to erupt again, active volcanoes are likely to erupt again, and dormant volcanoes do not know whether they will erupt again or not (it is not known if they will erupt again).
-
Extinct volcanoes do not erupt, active volcanoes do.
-
One has the potential to erupt, and the other two are safe for the time being or forever.
-
According to the nature of their activity, volcanoes are divided into three types: active volcanoes, dormant volcanoes, and extinct volcanoes.
Active volcanoes: Active volcanoes, including those that are still erupting regularly and those that have not erupted for a long time but have erupted in human history.
Dormant volcanoes: Volcanoes that have not erupted for a long time, but will erupt in the future. It is a sleeping volcano that has left the crustal movement zone and temporarily ceased its activity, and once it re-enters the crustal movement zone, there is a chance that it will erupt again.
It is difficult to draw a clear line between it and an active volcano.
Extinct volcanoes: volcanoes that are no longer active, and some still have volcano-specific morphologies, but there is no record of eruptions in history, and there are no active manifestations.
Other AnswersGenerally speaking, only active volcanoes erupt occur. Volcanoes that are erupting and are expected to erupt again can certainly be called active volcanoes. And those dormant volcanoes, even if they are alive, but are not going to erupt now, and volcanoes that may erupt again in the future can also be called active volcanoes.
Volcanoes whose last eruption is long ago and have been shown not to erupt in the foreseeable future are called extinct or extinct volcanoes.
Active volcanoes are volcanoes that have often erupted during human history, such as the famous Mount Vesuvius in Italy and some volcanoes in Indonesia; An extinct volcano is a volcano that has not erupted in the period of human history, but an extinct volcano is not necessarily completely dead, and it may erupt someday in the future, and most of the volcanoes in our country are extinct volcanoes.
If the computer is turned off, the computer will lose power, and if the computer is turned back on, the operating system will re-read the system files. Sleep, compared to hibernation, this mode also saves the current worker in memory, but it has not been powered off yet. >>>More
It is too hot in summer, and it hides in a cool and damp place when it is dry, and hides in a leeward corner when it is cold in winter, and secretes mucus from its feet when it is dormant, and forms a layer of breathable and impermeable membrane after drying, which seals the snail shell.
From the start menu, find the "Accessories" command prompt, manually enter the following command: powercfg -a, from here you can clearly see that the computer supports hibernation, displaying "Hibernation not enabled"。Still in the command prompt, start the sleep method: >>>More
