clicking on the register tab beside the "i" symbol opens and closes the register card with the volcano indices resp. informations about specific Earthquakes, volcano eruptions or Tsunamis
35 = volcano + number). You find the name of the volcano and all infos in the registercard!
= volcano is active (yellow to orange alert)- notice last update time in the register card
= volcano is erupting (red alert- levels 1-4)- notice last update time in the register card

I began this reports in 2011 when the maps were completed . Everything needs a good while to be developed. In November 2011 I decided to make monthly reports those will be updated once per week. From 2012 on, you will find all archived reports( including video sources) by my new archive directory.

MAIN TECTONIC ACTIVITIES IN 2011
final review to 2011 ( minor plates are included)
NORTH AMERICAN PLATE
Earthquake activities there were rather normal in 2011 . Significant new acticvities occured in Aug 2011 on the East Atlantic coast. of the USA, Continuing new activities also where registered in nearby regions of Central USA , such as near Oklahoma
SOUTH AMERICAN PLATE
No real major or disastrous Earth quake event in South America in 2011 . Some signficiant activities were registered offshore of Columbia down to Peru at begin of the second half in 2011
PACIFIC PLATE
The Pacific Plate and its surrounding minor Plates are generally in a grip by the Eurasian and North/ South American Plate. The seismic activity around Australian plate occures mostly in the regions Vanuatu to Fijji. Compared to the recent years the strength and frequency of the typical Earthquake activities there was rather low in 2011
INDO/AUSTRALIAN
The INDO Australian Plate seems to be pushed by both- the movement of the South American Plate around the Yucatan peninsula towards the Northwest and the (increasing) movement of the Eurasian plate towards the Southwest into Southwest direction against the African plate While the subduction zone along the coast of Sumatra and Java was very quiet in 2011, volcanic activities shifted from one site of the large Indonesian archipelago to the other and occured mainly on the Souther borders of the Indian tectonic plate For almost one decade, Indonesia whad been somewhat like the epicenter of the world . After March 2011 almost all major activities from there seemed to have shifted from there more than 100 km Eastward to the quadriple junction offshore of Honshu Japan, possibly pushed by an increased activity of the African plate ( yet thought to be one of the most quiet tectonic plates on Earth)
EURASIAN PLATE
Not many geologists seem to have taken notice yet from the increasing activities around the Eurasian plate recorded since begin of 2011. Until August a large number of minor and larger Earthquakes with magnitudes up to 6.5 occured all along the subduction zone in the South of Europe reaching from the AZORES through Gibralter over Italy, Greece into Turkey and Iran. Approximately the double number events were registered in 2011 compared to 2010. The average strength of the quakes along the boundaries of the Eurasian to the African plate also increased 2011 with at least one point on the Richter scale from M 4 to 5. Europe`s active volcanoes in the Mediterranean Sea, Etna and Strombili, had regular eruption activity increasing in strength and were sveral times setv on red alert level . Greece geologists reported , to have noticed a significant activity increase also of the Santorin Volcano in 2011. Santorin is hot spot volcanon situated on the tripple conjunction of Europe with the African and Arabian plate and is the rest of a shield volcano that was torn apart by a large hydrogen explosion around 1500 BC . Volcanic magma material from that explosion was even found in the Arctic region.The explosion recorded as one of largest volcanic events in history just left a sickle of the formerly round island with a submarine crater rest in its middle ,just reaching up to sea level
As the European plate is very massive, Earthquake magnitudes of 5.0 effect equal to magnitudes of 6.0 in other subduction zones and are counted as such.
In the spreading zone to the North American continent in North Europe Earthquakes activities in 2011 even were more intensive than in all recent 5 years together . Numerous larger seismis shocks were registered on the boundary of the North American and Eurasia plate in 2011 mainly during the Arctic summer. All occured exactly on the boundary between the Eurasian and North American plate from the Norway latidude through Iceland up to the Eastern coast of Greenland and seem to creep more and more Northwards. Major seismic shocks up to M 4.9 ( volcanic "tremors") were also measured near to the Iceland volcanoes of Grimssvoetn, Hekla and Katla in 2011 yet and are believed to be sign of an upcoming large an d major eruption While Katla does not show any significant signs of an eruption on the surface yet, in July 2011 the increasing activity in its interior suddenly melted the ice cap above the crater and the melting water rushing down form its flanks destroyed a bridge.
Some Seismic shocks with magnitudes up to M 4.6 o also were measured along the continental shelf of Scandinavia since 2011.,those were stronger to the North than to the South. There is no known active volcano around. As I have in suspect, this can only be an indicator for some new or old brake between Iceland and Norway, which may extend already further to the South ( either towards the Atlantic ridge or even between Great Britain and Scandinavia.
The most interesting as well as unprecendented event in 2011 was and is the sudden activity of the El Hierro shield volcano, that forms the most Southern island the Canary islands. More than 10.000 seismic tremor shocks were registered between June and September 2011 South East and North West of the island, before a new subsea volcano Southeast of La Restinga began to erupt.

AFRICAN PLATE
AND MID-ATLANTIC RIDGE
Activities also increased along the entire Atlantic ridge. Africa is usually the most quiet and slow tectonic plate of all. In the South an old equatorial brake off from the African continent begins at the horn of Africa/ arfur depression and stretches from there 6000 km into Southwest direction. This spreading process suddenly increased from some millimeters per year to meters per year early in 2005 , soon after the megaquake of M 9.6 had occured SW of Sumatra on 2004-12-26. This increased tectonic movement seems to create the regularly observed Seaquakes up to M 6.0 on the S- Mid Atlantic ridge and pressures towards Central and South America with an effect onto the Caribean Plate. The Northern Atlantic at least is surely known to be a spreading zone. What concerns the Southern Atlantic ridge,I won´t be sure about anymore! I don`t know much about, but guess, the Atlantic as such was almost quiet since thousands of years. Nevertheless, earthquake activities are known to be extremely seldom in and along the Atlantic , tzhey usually occure if then on its boundaries to Africa and the Carribbean . The last one known in the 20 Century was the Agadir quake in 1960, which had a magnitude of not much more than M 6.0 , but lasted for several minutes, during these it leveled the entire town. The disastrous Quake that destroyed Haiti in 2010 again proved ,that if those earthquakes occure there, they come rather unprecedented ( without warning or prequakes) but hard with intensive movements and mostly very disastrous. IN 2011, higher activities couold be found at the Western boundaries of the Atlantic to the Carribean near to Puerto Rico with magnitudes up to M 5.9

Uturuncu volcano - Magma is rising in the Bolivian volcano that last erupted 300,000 years ago. "Uturuncu -- a volcano in the Bolivian Andes Mountains -- was thought to be inactive," Cornell geologist Matt Pritchard said in a university release Tuesday. "The region is populated by 'supervolcanoes' that erupted between 1 (million) and 10 million years ago....read more...
