The causes and topographical distribution of volcanoes in El Salvador

On April 3, a magnitude ** occurred in the southern waters of El Salvador, a Central American country, with an epicenter depth of kilometers. El Salvador, a coastal country located in the northern part of Central America, is also the most densely populated country in Central America. El Salvador borders the Pacific Ocean, with a land area of 20,720 square kilometers and 14 provinces.

In 2013, the country had a total population of 6.3 million. The domestic terrain of El Salvador is dominated by mountains and plateaus, with many volcanoes, known as the "country of volcanoes", and the active volcano of Santa Ana is 2,385 meters above sea level, which is the highest peak in the country; The country is bordered by the Lampa River valley in the north and a narrow coastal plain in the south. The whole territory of El Salvador has a tropical climate, with an average annual temperature of 28; The dry season is from November to April, and the rainy season is from May to October. The coastal and lowland climate is hot and humid, and the mountain climate is cool; Annual precipitation is more than 1,800 mm in mountainous areas and about 1,000 mm in coastal areas.

El Salvador's domestic economy is dominated by agriculture, mainly rich in coffee beans and cotton, with a weak industrial base, and is one of the world's "low- and middle-income countries", affected by the international economic and financial crisis in 2008, and the economic growth is slow; The official language of the country is Spanish, and the indigenous language is Nahua.

Volcanic origin: El Salvador is located in the zone where Antarctica collides with the American tectonic plate.

Indonesia is known due to the numerous islands and volcanoes"The Land of a Thousand Islands"with"The Land of Volcanoes"。

The Republic of Indonesia is composed of about 17,508 islands, is the world's largest archipelagic country, the territory spans Asia and Oceania, also known as the "country of a thousand islands", but also a volcanic and multi-volcanic country, the capital is Jakarta. It is bordered by countries such as Papua New Guinea, Timor-Leste and Malaysia.

Indonesia is located at the junction of the Indian Ocean plate and the Eurasian plate, where the two major plates squeeze each other, and is in the Pacific Island arc chain, with multiple volcanic ** belts, active crustal movements, and many volcanoes**.

The Republic of Indonesia (Indonesian: Republik Indonesia, English: The Republic of Indonesia), abbreviated as Indonesia or Indonesia, is a country in Southeast Asia.

Composed of about 17,508 islands, it is the largest archipelago country in the world, with a territory spanning Asia and Oceania, also known as the "country of a thousand islands", and is also a country with many volcanoes and many **, with the capital of Jakarta. It is bordered by countries such as Papua New Guinea, Timor-Leste and Malaysia.

Indonesia is located at the junction of the Indian Ocean plate and the Eurasian plate, where the two major plates squeeze each other, and is in the Pacific Island Arc Chain, with multiple volcanic ** belts, active crustal movements, and many volcanoes**.

Japan is a world-famous country with many volcanoes and is known as the "Land of Volcanoes".According to statistics, there are about 270 large and small volcanoes in the country, accounting for one-tenth of the total number of volcanoes in the world, and are an important part of the largest volcanic belt on the earth's surface, the Pacific Rim Volcanic Belt.

Indonesia, I'll make up some more brailles.

1) The climate is hot and humid, not suitable for human habitation;

2) The terrain is low and flat, and floods are frequent;

3) The coastline is straight, which is not conducive to the construction of ports.

El Salvador is located in the tropics, with a climate that transitions from savannah to tropical rainforest.

Therefore, the coastal area is flat, relatively humid and hot, and the rainy season is prone to waterlogging and waterlogging. Therefore, it is not conducive to the life of the people, and the city is scarce.

On the contrary, in mountainous areas, the climate is cool, although humid, but because of the altitude difference, the drainage conditions are much better. Relatively conducive to people's lives, cities have been formed at higher altitudes over time

[Climate problems, because only the southeast of Australia has a relatively humid climate and is suitable for habitation, and the rest of the country is arid and rainless, and is in a desert area.

The southern coastal region of El Salvador is low-lying and has a hot and humid climate, which is not conducive to people's life, and the population here is relatively sparse, so there is less urban distribution.

I don't know the reason for the lack of foot-stopping cities in the southern coast of El Salvador.

Because this coastal city is relatively small, it is due to the terrain that there are many mountainous areas in that place, so it is generally not suitable for the development of communities.

The reason why El Salvadona is not distributed less coastal cities, because it is more inhospitable and there are more coastal cities, so the cities are distributed.

The reason for the lower distribution of coastal cities in southern El Salvador is definitely the shorter coastline.

The living environment on the southern coast is not good, and it is not easy to carry out urban construction.

There are too many reasons for this to go into full.

Antarctica: It is a continent covered with ice and snow all year round, and the focus should be on the causes of the formation of the Antarctic climate, the local polar day and night time, the main climate throughout the year, the local living conditions, the mineral resources of Antarctica (rich in coal and iron), local biodiversity, and krill resources.

Located in the northern part of Central America. It is bordered by Honduras to the north, the Pacific Ocean to the south, Guatemala to the west and northwest, and the Gulf of Fonseca in the Pacific Ocean to the east. The smallest and most densely populated country in Central America.

The topography is dominated by mountains and plateaus, with many volcanoes, and the active volcano of Santa Ana is 2,385 meters above sea level, which is the highest peak in the country; to the north is the Lampa River Valley; The southern part is a long and narrow coastal plain.

There are more than 500 active volcanoes in the world, mainly in the area around the Pacific Ocean and on a series of arc-shaped islands centered on Java, as well as in the Mediterranean, mid-Atlantic and eastern Africa, especially around the Pacific Ocean.

The Pacific Volcanic Belt, also known as the Pacific Volcanic Ring, starts from Alaska in the United States, passes through the Kamchatka Peninsula in Siberia to the Kuril Islands and Japan, Taiwan Province of China, the Philippines, Indonesia, New Guinea, New Zealand and reaches the west coast of South America. There are more than 20 active volcanoes in Kamchatka, the most famous of which is Kryuchev Volcano. There are nearly 100 active volcanoes in the Kuril Islands and Japan.

There are more than 60 active volcanoes in the Ryukyu Islands through Taiwan to the Philippine Islands, Irian Islands and New Zealand Islands, as well as on the seabed near these islands, including more than 10 in the Philippines. Volcanic activity is also high on Irian Island, New Zealand and Antarctica. There are nearly 100 volcanoes on the western edge of the Pacific Ocean, a collapsed arc island centered on Java.

Between 1966 and 1970, there were 22 volcanoes erupting in Indonesia, so it's no wonder that Indonesia is known as the "Land of Volcanoes". On the east coast of the Pacific Ocean, on the Aleutian Islands and the Alaskan Peninsula at the northern end, there are nearly 30 active volcanoes, among which the Katmai Volcano, which created the miracle of the "Valley of Ten Thousand Smokes", is on the Alaska Peninsula. To the south, Mexico's volcanoes such as Parriyanku and Zorluno are famous.

In Central America, Guatemala, El Salvas, and Costa Rica are all volcanic countries. There is a volcano called Isarco on the coast of El Salvador, which erupts every few minutes to ten minutes, and ships that sail at night use it as a lighthouse! Further south, western Colombia, Ecuador, Peru and Chile are also volcanic areas.

The world's highest active volcano, Cotopaxi, is located in Ecuador.

the numerous volcanoes of the Pacific Volcanic Ring; Together with the volcanoes in the central Pacific Ocean and the volcanoes on the arc-shaped islands of Java, which are closely connected to the Pacific volcanic ring, they account for four-fifths of the world's active volcanoes.

As for the origin of the Pacific Ring of Fire, many scholars believe that it is related to plate movements. Because the western half of the Pacific Rim Volcanic Belt** is the boundary between the western limit of the Pacific Ocean and the Eurasian and Australian plates; The eastern half is the boundary between the Pacific and American plates; The southern half is the boundary between the Pacific and Antarctic plates. It is not surprising that there are many volcanoes in the plate dividing zone.

Guatemala is located in Central America, its northern lowland plains are tropical rainforests, the central highlands have volcanoes up to 4,200 meters, and the narrow and rich flatlands on the Pacific Ocean have a tropical climate.

The central highlands are also the cultural center of Guatemala, where temperatures are mild all year round at altitudes of 1,300 to 1,800 meters, with daily temperatures ranging from 18 to 28 degrees Celsius, and higher altitudes tend to be colder in January and February. Guatemala City, the capital of Guatemala, is also here. With 2.5 million inhabitants, it is the largest city in Guatemala.

The tourist centers are Lake Atitlan, the old capital of Old Guatemala, the ancient Mayan city of Tikal and some other famous cities such as Quetzaltenango and Chichicastenango.
