Science quote of the day:

Geology: Hawaiian volcanoes - Part 9: Predicting Eruptions
Original post by 
In my last post we have looked at the different methods that are used to monitor the behaviour of a volcano. The observed behavioural patterns for the two active volcanoes on Hawai'i, Kïlauea and Mauna Loa, are fairly regular. The precisely recorded history of deflation and inflation is observing the times in which new magma is supplied or released into or from the volcano. The moving magma creates stress on the surrounding rocks causing different types of small earthquakes. During times of inflation, gradual volume changes in the magma chamber create high-frequency, short-period earthquakes. The magma release causing deflation is more abruptly and creates low-frequency, long-period earthquakes.

@pinasKnowing the details bit by bit of something that is of great importance to you is more than overwhelming. For quite a while now, I have been enjoying my leisure time reading Laurence Bergreen's Over the Edge of the World. The book is about the terrifying adventure of the great explorer Ferdinand Magellan into the Pacific. The crispiness of the details is what I like the most. The author really knows how to take you back in time. Magellan's fleet sail off to the Pacific in search for the Spice Island but they found themselves in the Island of Thieves, in Guam.
