Alaska's Bogoslof Volcano, which has exploded even more than 35 times since the middle of December 2016, became active again on Monday, March 13.
According to the Alaska Volcano Observatory (AVO), the Bogoslof Volcano exploded just after a while at 11:31 AM UTC, which takes the count of eruptions to 37. It lasted for around 12 minutes and, according to the satellite data, resulted in an ash cloud.
Winds would have moved the ash cloud to the southwest, noted the AVO. However, this volcano eruption did not urge authorities to issue any aviation warning notice for the pilots.
"We are evaluating the magnitude of this eruptive episode. Although the episode appears to be over and of short duration, additional activity is possible. The Aviation Color Code remains at ORANGE and the Volcano Alert Level remains at WATCH at present. AVO is evaluating all data sources and will update this report as more information becomes available," noted the organization.
What Is Bogoslof Island?
Bogoslof Island is the head of a volcano which has its major part under the water and expands 5,500 feet down like a cone shape to the ground of the Bering Sea. The island made its first appearance in the year 1796 after an underwater explosion. Several explosions then changed the shape and size of the island. The present explosions are happening from an insubstantial underwater space located on the southeast side of the island.
Previous Volcano Explosion
The previous eruptions occurred at Bogoslof Volcano on March 7 night and March 8 morning. These produced the biggest ash cloud which made the authorities put out a warning for the aviation and a large fishing port of the U.S. Aleutian Islands as the ash cloud could cause several problems.
According to the AVO's report, the volcano exploded for the 36th time on March 7 and expelled ash for almost three hours, which made a massive cloud that went up to 35,000 feet.
"It was the most significant event for the entire eruption," said Kristi Wallace, US Geological Survey geologist.
Effects Of Volcanic Ash Clouds
Ash clouds that go more than 20,000 feet up in the air are a major risk for the flights flying between Asia and North America. Air traffic controllers get warnings after major explosions and issue alerts for the pilots to either fly around, or above the ash clouds which can remain still for hundreds of miles.
The ash clouds caused by volcanoes have the ability to destroy jet engine turbines blades. According to the AVO, when the ash comes to the connection with the engine, it melts down because of the high temperature and sticks to the crucial parts of the engine. This may cause engine failure, as well as damage to the cockpit windows and create obstructions in the navigation system's electronics.
Fine volcanic ash in the air of cities can affect respiratory system by causing several problems for humans, as well as animals. It also hampers electrical devices and destroys air filters and gasoline engines.
