Causes of mud vol­ca­noes erup­tions named

Azer News - - Nation - By Narmina Mam­madova

Ex­ca­va­tion work car­ried out near mud vol­ca­noes pro­voked their erup­tion, the head of the mud vol­can­ism de­part­ment of the In­sti­tute of Ge­ol­ogy and Geo­physics of the Na­tional Academy of Sciences of Azer­bai­jan (ANAS), Pro­fes­sor Adil Aliyev told Trend on Novem­ber 2.

The head of the de­part­ment noted that the hu­man fac­tor pro­voked the erup­tion of some mud vol­ca­noes in Azer­bai­jan.

“In par­tic­u­lar, Kechyaldag vol­cano lo­cated near the Jeyran­batan reser­voir erupted in 2000. It is noteworthy that un­til this time we did not record the ac­tiv­ity of this vol­cano. The erup­tion of the vol­cano was due to the fact that dur­ing the lay­ing of the pipe­line line near the crater, earth­works were car­ried out. In turn, the crater of the vol­cano has un­der­gone ero­sion. As a re­sult the vol­cano woke up. We be­lieve that the erup­tion of this vol­cano was also pro­voked,” Aliyev said.

Aliyev noted that the ex­ca­va­tion work car­ried out in 2001 near the crater of a vol­cano lo­cated near the vil­lage of Lok­batan also led to a strong erup­tion of the vol­cano.

There are 1,400-1,500 mud vol­ca­noes on Earth. More than 300 of 700, that is more than 45 per­cent of all mud vol­ca­noes are con­cen­trated on the ter­ri­tory of Azer­bai­jan, while most of them are lo­cated on the Ab­sheron Penin­sula. Mud vol­ca­noes ap­peared on the ter­ri­tory of the present Azer­bai­jan Repub­lic 25 mil­lion years ago.

Mud vol­ca­noes by ori­gin are as­so­ci­ated with oil and gas fields. Rich de­posits of gas con­den­sate and oil (Lok­batan, Garadagh, Oil Rocks, Mishovdag, etc.) were found in these ar­eas. In ad­di­tion, the mud and liq­uid that mud vol­ca­noes spew are used as raw ma­te­ri­als for the chem­i­cal and con­struc­tion in­dus­tries, as well as for phar­ma­col­ogy.

Mud vol­ca­noes are lo­cated far from pop­u­lated ar­eas. Most of these ter­ri­to­ries are un­der pro­tec­tion, and it is strictly for­bid­den for peo­ple to en­ter there with­out spe­cial per­mis­sion. Oth­er­wise, ev­ery­one will face a large fine - for in­di­vid­u­als the amount is 400-600 man­ats, and for of­fi­cials – 2,000-4,000 man­ats.

These bans have sev­eral rea­sons. Firstly, in this way the ter­ri­tory of the vol­ca­noes is pro­tected from pos­si­ble con­tam­i­na­tion by peo­ple, se­condly, pos­si­ble at­tempts to carry away the mud from the ter­ri­tory of the re­serve are pre­vented (this mud can be used dur­ing con­struc­tion). And fi­nally, the main rea­son is that each erup­tion vol­cano is a dan­ger to hu­man life. Vol­canic erup­tions have oc­curred on the ter­ri­tory of Azer­bai­jan many times. The first erup­tion of the vol­cano oc­curred in 1828. It was lo­cated 15 km from the cap­i­tal Lok­batan vol­cano, and it has erupted 17 times since then.
