Another big eruption is still ongoing in the Canary islands. Earthquakes have reached 4.2 on the Richter scale, and the ground is still rising on the mountain, showing that the magna is still building underneath. This eruption could go on for several more weeks. And, there still is a danger of the mountain sliding into the sea that might create a dangerous tsunami that would hit the east coast of America.

What is causing this? I would say it is the influence of the sun with higher solar activity taking place at this time. This can stir up the magma deep inside the earth and cause the pressure to break out more often and in greater amounts.GE
