Does it threaten a megatsunami?

A long, long time ago, 73,000 years to be exact, the eastern face of a volcano collapsed in Cape Verde.This caused a wave of gigantic proportions, which rose to 170 meters high and then crashed with enormous force in a nearby island. This megatsunami , as it was baptized in the journal Science Advances , is the largest one with a geological record. They say it can happen again This is stated by Ricardo Ramalho , a geophysicist at the University of Bristol, although he clarifies that it cannot be known exactly when or where. The problem is the young oceanic volcanoes-such as those found in the Canary Islands or the Azores, or Hawaii-that have very high altitudes and steep walls; the scientist believes that the potential disaster is there, if it happens again with certainty it will originate in these volcanoes. The flanks of some of the oceanic volcanoes collapse periodically, causing huge amounts of rock they slide down and the water moves below; This is how tsunamis f...

According to the Professor Hans Reul, who directs the research, stress hormones, such as cortisol and adrenaline, change genes within neurons and increase their learning capacity .
