Is it forming a new tectonic plate?
(CBS News) "A new study suggests that two recent earthquakes may indicate a literal seismic shift in our understanding of tectonic plate movements. Massive earthquakes under the Indian Ocean that took place last spring are the largest of their kind ever recorded. The 8.7 magnitude quake, followed by a 8.2 magnitude aftershock, could signal the formation of a new plate boundary under the Earth."

Lycanthropus, by C. EDGAR BOLEN
The jellied night has oozed its miry black
From out the hills to fill the valley floor.
Atop the ragged hills the torn cloud-wrack
Is lightning-limned into a hellish door.
A gust of wind across the sky is hurled—
The gods of old are loosed upon the world.
Age-old, the blood-lust wells within my throat;
Tensely I wait, and feel my body shrink;
My hairless hide becomes a furry coat.
Blood-hungry, through the opened door I slink;
I raise my head and howl in horrid glee—
And from the plain a howl comes back to me.

What is Cornelius Nepos telling? And Pliny?
The world's first seismometer was Chinese
Who was the inventor of the first siesmometer?
Zhang Heng. He was (AD 78–139) a Chinese astronomer, mathematician, inventor, geographer, cartographer, artist, poet, statesman. He lived under the Han Dynasty (AD 25–220) of China. He was a Chief Astronomer, Prefect of the Majors for Official Carriages, and then Palace Attendant at the imperial court. He invented the world's first water-powered armillary sphere, improved the inflow water clock by adding another tank and invented the world's first seismometer, which discerned the cardinal direction of an earthquake 500 km away. He improved previous Chinese calculations of the formula for pi. In addition to documenting about 2,500 stars in his extensive star catalogue. Some modern scholars have also compared his work in astronomy to that of Ptolemy (AD 86–161). (Adapted from Wiki)

"In 132 CE, after several serious earthquakes in China, astronomer Zhang Heng invented this instrument to warn people of the next one. When the ground shook, it moved a pendulum inside the jug. The pendulum pushed a lever that opened one dragon's mouth. A ball rolled out and into the toad's mouth below, sounding an alarm. The open dragon mouth pointed in the direction of the earthquake, notifying the Emperor."http://en.wikipedia.org/wiki/File:EastHanSeismograph.JPG

Ancient solar observatories: Stonehenge
This is Stonehenge. The image shows directions of sun during the day. “The lines on the drawing show the direction and height (altitude) of the sun throughout the day. Thicker and shorter lines mean the sun is higher in the sky. Longer and thinner lines mean the sun is closer to the horizon”, according to Sollumis.com http://www.sollumis.com/. The site is located in the Google Maps. The direction of the sun is given on the summer solstice, choosing an altar at the circle for observation. We see that, at sunrise, the sun is passing near the stone outside the circle.
