After the first eruption, a tsunami swept across the Sunda Strait, toward Sumatra and toward Java. This was followed by a second eruption. Anka Krakatau\u2019s most recent prior eruption was in July.<\/p>\n
In the town of Pangdelang, a concert was underway on the beach, with over 200 concert goers and a band named \u201cSeventeen\u201d. They are now missing and presumed dead.<\/p>\n
It is daylight by now in Indonesia. Vulcanologists are trying to determine if the tsunami was caused by a slide of part of Anak Krakatau\u2019s cone to the sea floor, displacing seawater and generating the tidal wave. The Sunda Strait is narrow, which channels these giant, destructive waves into focused trains.<\/p>\n
As you may recall, in 2004, the 12\/26\/2004 Boxing Day earthquake at Banda Aceh on the west coast of Sumatra was a 9.2 quake that created a massive tidal wave which rolled across that area as if it did not exist, pulled back and rebounded across the Indian Ocean, and rebounded again toward Sumatra. The possibility that the tsunami might reach the west coast of the US was very real. Hawaii did get a flood that was up to 1 meter deep and the wave rolled further east toward California. Over 288,000 people lost their lies to that earthquake-generated wave of destruction.<\/p>\n
Anak Krakatau is the successor volcano to Krakatoa\u2019s massively self-destructive eruption for two days in August, 1883, which sent a tidal wave in all directions before the caldera collapsed inward. That massive eruption not only caused damage everywhere the tsunami that it created went, but also dropped the temperature worldwide by 1 degree Celsius.<\/p>\n
A plinian eruption, which is what Anak Krakatau engaged in, is very similar in its shape to a nuke explosion. Same shape, same shock wave, same rebound.<\/p>\n
Anak Krakatau is the result of filling a new magma chamber to revive Krakatoa\u2019s extinct caldera. This has been going on since 1927.<\/p>\n
There is no such thing as a truly extinct volcano. They tend to move with the Earth\u2019s plate movements. Mount Damavand\u00a0 a potentially active volcano, is a\u00a0stratovolcano which is the highest peak in Iran and the highest volcano in Asia. Erta Ale in Ethiopia’s Danakil Depression is the most dangerous volcano in the world.\u00a0It sits on three plate boundaries, and the caldera has finally filled to the brim and is spilling over. \u00a0The Earth’s crust there is less than a half mile thick, whereas it is normally 18 to 20 miles thick on land, and at the bottom of the oceans, barely 3 miles thick.<\/p>\n
The US Navy has a base at Sigonella, Sicily, below the very active volcano Etna. While there has been recent speculation about a revival of activity in the Alban Hills volcano complex south of Rome, it is more likely that the magma is moving under the sea bed to Etna\u2019s magma chamber.<\/p>\n
Why do these things matter? Because they affect everything that we take for granted if they are severe enough events. \u00a0If you will recall, Iceland’s Eyafyalajokull shut down all air traffic in Europe and between Europe and the US\/Canada until it simmered down. Pinatubo forced the evacuation of Clark Air Force Base in the Phillippines.<\/p>\n
Keep the missing people from this disaster in mind when you’re having Christmas.<\/p>\n
