San Simeon is known by many tourist travelling from San Fransisco to Los Angeles. A lot of tourist did visit Hearst Castle, a National Historic Landmark mansion located on the Central Coast of California, United States. It was designed by architect Julia Morgan between 1919 and 1947 for newspaper magnate William Randolph Hearst, who died in 1951. In 1957, the Hearst Corporation donated the property to the state of California. Since that time it has been maintained as a state historic park  where the estate, and its considerable collection of art and antiques, is open for public tours. Despite its location far from any urban center, the site attracts roughly one million visitors per year.

We have given a preliminary color of orange because of the nearby city of Calama as the events took place only 15 minutes ago. If the Magnitude and depth numbers are confirmed, we will change our color coding to green.
Local newspaper El Mercurio de Calama just reported that people were frightened by the shock, but told also that NO disruption of the power took place.

Minor earthquakes are earthquakes without or with little damage risk.  In most cases these earthquakes have a Magnitude smaller than M 5.0 OR earthquakes with an hypocenter (depth) of more than 100 km OR earthquakes up to M 5.9 with an epicenter far away from populated areas.

Colombia : Red alert for possible eruption of Galeras Volcano

Volcán Galeras - Pasto - Colombia

The Colombian authorities have declared the maximum alert for Galeras volcano and forced 8000 people living in and around 7 villages nearby the volcano to abandon their houses and to evacuate  for safer grounds.

The Galeras volcano has a history of short but violent eruptions.

The ‘Red Alert’ has been called after a singificant event took place at 4 AM Columbian time on August 25, 2010.

Galeras (Urcunina among the 16th-century indigenous people) is an Andean stratovolcano in the Colombian department of Nariño, near the departmental capital Pasto.
Its summit rises 4,276 metres (14,029 ft) above sea level.

The South American volcanoes are products of the tectonic interaction in between the Nazca and Cocos plates and the South American plate (subduction) .

Recent eruption history

A 1993 eruption killed nine people, including six scientists who had descended into the volcano’s crater to sample gases. It is currently the most active volcano in Colombia.

More than 100 minor tremors were felt during a major eruption in April 2002, although no damage or injury was reported.

An eruption in November 2005 forced an evacuation of the dangerous area surrounding the volcano, and about 9,400 people from nearby villages (most of them farmers) were ordered to leave. The city of Pasto, about 9 kilometres (5.6 mi) from the volcano, was blanketed by a layer of ash after the volcanic explosion, forcing the residents to don goggles and face masks.

Numerous minor tremors and ash emissions since March 2006 culminated on 12 July 2006 in three explosive eruptions, producing an ash and gas column reaching an altitude of 8 kilometres (5.0 mi).
Rock falls and pyroclastic flows were reported from towns as distant as Consacá, 11.4 kilometres (7.1 mi) west of the main crater.

On January 17, 2008, the volcano erupted around 20:06 (local) (01:06 UTC). There were no immediate reports of injuries or serious property damage. Later the experts confirmed partial damage in the national and local TV towers.

on February 14, 2009, the volcano erupted around 19:10 (local) (00:10 UTC).  Some 8,000 residents were evacuated, and there were no immediate reports of injuries or serious property damage. As in 2005, the city of Pasto was blanketed by a layer of ash after the volcanic explosion (due to the direction of the wind). The local authorities ordered two water treatment plants near Galeras to shut down.

On March 13, 2009, Galeras erupted twice at around 15:55 and 17:00 (local time). Ash fell on Pasto and some other towns near the volcano, where an evacuation was ordered but reportedly ignored. No injuries or damage were reported.

The volcano erupted on January 3, 2010, forcing the evacuation of 8,000 people. This is the 10th such eruption of the volcano in the past year, and the first of 2010. Colombian authorities also stated that it could remain volatile in the weeks to come.
