On a rainy, misty day scienceviews.com/islands/hawaiianrocks.html The black sand that makes up the famous Hawaiian black sand beaches is made out of basalt. These beaches can form rapidly when molten lava meets the cold ocean water in an explosive confrontation. The shattered volcanic rock is further broken down as it is smashed together by the waves. Black sand beaches can be relative short lived. This photo shows the black sand of Maui's Pa'iloa beach.

Seventy four thousand years ago, give or take a few millennia, Homo sapiens had a very bad day, perhaps the worst day that we’ve ever experienced. On what is now the Indonesial Island of Sumatra, a mountain called Toba exploded -- though the word doesn’t do justice to the act of sheer geographical violence perpetrated that day. What happened to Toba was a destruction that scientists would eventually coin a term for volcanic disasters of its scale: supereruption. But the eruption was only the beginning. Toba’s aftereffects dimmed the sun and draped a volcanic winter around the world. It might have brought our species closer to the brink of extinction than ever or since. At a moment when Homo sapiens was far from the world-dominating force we are today, Toba was our ultimate trial. It was also a warning -- the most dangerous natural existential risk we face comes not from the skies above, but from the ground beneath our feet. ~ Excerpt “End Times” Author - Bryan Welsh
