Santorini Volcano – John Seach


36.4 N, 25.39 E
summit elevation 564 m
shield volcanoes

Santorini erupted in 1600 BC and buried the city of Akroteri and possibly gave rise to the legend of Atlantis.
Three islands remained after the eruption – Thera, Therasia, and Aspronisi.
Santorini caldera has a diameter 11 km N-S and 7.5 km E-W, with a depth of 390 m in the north.

The 1950 eruption of Santorini produced a lava dome, lava flow, and explosive activity.

2011-2012 Unrest
In January 2011 Santorini started to wake from 60 years of inactivity. The episode began with a seismic swarm and radial deformation of the volcano. The unreast has been interpreted as radial inflation of the volcano by 5-9 cm by a magma source, 4 km below the northern half of the caldera.

Minoan Eruption
About 1650 BC a series of Plinian eruptions at Santorini volcano expelled 40-60 cubic km of lava, and created a regional tsunami. This eruption was possibly the main factor in the destruction of the Minoan civilisation.

My comment: I think that there can be, because the earthquake  is not  a result from  an organic process,  apoptosis,  mitos etc, not even  about organic mass of  material – but  results  of physical  components of  anorganic  energy in and to the anorganic mass of the Earth. of caus its very multifunctional  calculation  with  need of  extremely much   data input. How  to   predeict  where the compression  should  appear next time.


“Geophysicists in the US have developed a new way of calculating the magnitude of an imminent earthquake by making better use of measurements of the compression waves produced early in the event. They say that the technique could be used to create a better early-warning system for earthquakes that could be used worldwide.

The majority of earthquake damage is caused by S-waves, which oscillate perpendicular to their direction of travel through the Earth, and by waves that occur on the surface. However, these are preceded by much faster-moving compression waves (called P-waves) that oscillate in the direction of travel and cause minimal damage. By making careful measurements of arriving P-waves, seismologists can get some idea of the strength of the impending earthquake. While this only gives officials tens of seconds to react, it is enough time to take some protective action such as slowing down high-speed trains, switching off gas mains and even warning the public to seek shelter.

Amplitude, period or both?

Current early-warning schemes make use of two properties of P-waves: the displacement amplitude of the P-wave’s vertical component (Pd) and maximum predominant period of the P-wave (τpmax). To understand how best to use these measurements, Huseyin Serdar Kuyuk and Richard Allen of the University of California, Berkeley looked at real-life data recorded from 1992 earthquakes processed by California’s real-time Earthquake Alarm Systems. They also looked at 174 earthquakes in California and Japan that have already been used in early-warning calibration studies. The earthquakes they studied varied in magnitude (M) from 0.2–8, with M = 8 being a major earthquake.

The team used these data to test five different methods for calculating Earthquake magnitude. The techniques use either Pd, τpmax or both to make their predictions. Some of the methods are already used in early-warning systems and one is a new technique developed by the researchers. The team found that its new technique – which is based on Pd measurements alone – gave the most accurate and robust estimate of earthquake magnitude. In contrast, methods that used τpmax did not do a good job of predicting the magnitudes of small earthquakes (M < 3). They were also less accurate than Pd-based techniques for larger magnitude events.


“Astronomers have discovered the first pulsar with two stars circling it. By watching the three objects orbit one another, observers will soon be able to perform the best-ever test of the “strong equivalence principle”, which is a key prediction of Albert Einstein’s general theory of relativity.

Like the Newtonian theory of gravity that came before it, Einstein’s general theory of relativity says that gravity does not discriminate: it accelerates all objects equally, no matter what their size, shape or composition. Apollo 15 astronaut Dave Scott demonstrated this so-called equivalence principle on the Moon in 1971 by dropping a hammer and a falcon’s feather, which hit the lunar surface simultaneously.

The strong equivalence principle of general relativity goes further, saying that gravity should accelerate all objects in the same way even if the objects hold themselves together with their own gravity. In other words, the gravitational self-energy that binds a planet or star together should have no effect on how it is accelerated. This is unlike theories that seek to topple general relatively and predict a small deviation related to gravitational self-energy called the Nordtvedt effect.”

“The most exacting test of the strong equivalence principle performed so far involves tracking the Earth and the Moon. As they orbit the Sun, both are continually falling through the solar gravitational field. Einstein’s theory says that the Earth and the Moon should behave the same, even though the Earth has greater self-gravity. Precise laser-ranging measurements of the distance between the two bodies back this up by revealing no evidence of the Nordtvedt effect.”
