June 2016 – GEOLOGY – Several volcanoes around the world were very active last week spewing enormous amounts of ash and gas into the atmosphere and forcing thousands of people to leave their homes. But it´s not all just about volcanic activity, there has also been quite a bit of earthquake activity along some the volcano impacted areas, especially in the Pacific Ring of Fire.
During the last 10 days close to 40 volcanoes worldwide have been showing signs of activity and great deal of them, 34, are located along the very active Ring Fire. Considering that in the 20th century the average number of volcanic eruptions was 35 per year, what we are seeing just this week is above last century´s average for an entire year. This increasing volcanic activity around the Ring of Fire is not new, the region is home to 452 volcanoes, 75% of all earth’s, and geologists have been warning that this 25,000 mile stretch of active and dormant volcanoes is becoming more unstable in recent years.
During the weekend of May 21 and 22, the northern skies of the Indonesian island of Sumatra were covered with a thick black cloud of ash and gases resulting from the eruption of Mount Sinabung, Indonesia’s most active volcano. Several cities in the area were evacuated and in the village of Gembar, seven people lost their lives, all of them farmers, after inhaling deadly gases. Sinabung is one of the many active volcanoes in the island, and after showing signs of activity back in early November of 2014, many residents in the area were forced to relocate in other villages of northern Sumatra located at a safer distance from the volcano.
Mount Sinabung continued to show signs of activity late last week, and was still on the highest alert level with potential for more eruptions. One of the most active has been Turrialba in Costa Rica. The small Central America country has a dozen active volcanoes and it is located close to the capital, San Jose. Early last week, a prolonged and violent eruption dropped a significant amount of ash over the city and nearby towns, forcing many people to wear masks and in some cases evacuate entire neighborhoods. –Weather Network
