Can accurately guess the time when volcanoes are active

On August 9, US scientists said for the first time successfully judged the eruption time of one of the most active ocean volcanoes off the coast of the state of Oregon, western America. .

The scientists observed the Axial volcano, located 400km from the shore, since the eruption in 1998 and found that the crater was about 15cm higher each year due to the ghosting.

In 2006, the Axial scientists predicted that it would erupt again when its mouth reached its height as in 1998 and that time fell before 2014. The fact that this volcanic activity had taken place was true. .

During an expedition last July, using remote control robots, the researchers discovered a lava flow in the Axial volcano area that had not appeared last year. They also realized the difference of the entire area explored and found no markings as well as installed observation devices.

Then, through a pressure sensor, like a sea floor inspection device to assess a tsunami risk after an earthquake, scientists determined that the Axial eruption happened on April 6. 2011

Most volcanoes, especially volcanoes on the mainland, are complex and unstable, so their activity is difficult to predict. However, scientists now have evidence of more predictable activity of Axial ocean volcanoes compared to other volcanoes.

Experts claim that the acid test method combined with these natural and scientific observations can be applied to other ocean volcanoes, even to land volcanoes.
