history

The first days of 2011 began with a series of strong earthquakes:
January 1st with a magnitude of 7.0 in the province of Santiago del Estero in Chile, January 2nd with a magnitude of 7.1, and on 10th January with a magnitude of 6.0 off the coast of central Chile, January 12th with a magnitude of 6.5 not far from the Japanese Bonin Islands, and on January 18th with a magnitude of 7.2 in Pakistan.

Meanwhile, the catastrophic earthquake in Japan with a magnitude of 8.9 and the subsequent tsunami became an indicator of a new phase of global seismic activity that shocked the world forced. The earthquake showed that mankind appears to be weak and unprepared for natural disasters.

predictions

In the period up to 2015, several more catastrophic earthquakes with the magnitude of more than 8 as well as strong tsunamis are expected in Japan.

Indonesia, the Philippines, the western coast of North and South America are the regions next after Japan, where catastrophic earthquakes and tsunamis are expected.

The activation of one of the most seismically active faults of the world, San Andreas in California, is expected. San Andreas is a transform fault between the Pacific and North Atlantic plates, with the length of 1,300 kilometers. Catastrophic earthquakes with the magnitude of more than 8, for example, in San Francisco in 1906, are linked to this fault. The peak of seismic activity for the territory of the "Ring of Fire" falls on 2015.

The second after the “Ring of fire” to become active is the Alpine-Himalayan seismic belt, covering the territory of many countries of southern Europe, the Middle East, the Caucasus, Central and South-East Asia from the Alps up to the Himalayas.

This territory is expected to show the seismic activity mainly with the magnitude 5-6 impulses, exceeding 7 in some cases.

The earthquakes of the “Ring of Fire”, with the largest volcanoes in Japan, the Far East and Indonesia in the first place, will be the first to become active, as they will with the seismic activity. Identified jointly with academicians Viktor Khain, Shafayat Mehdiyev and Tofig Ismail-Zadeh, the mechanism of the spatial-time distribution of volcanic eruptions suggests that volcanic activity will increase with some delay in relation to seismic activity.

One of the greatest hazards is also posed by Krakatoa and Fuji volcanoes.

The eruptions of which resulted in massive losses and caused strong tsunami, often accompanied by catastrophic earthquakes. The peak of volcanic activity will fall on 2014-2015.

conclusion

Project engineers and building engineers who work on projects must consider all these factors and implement the security concept to the maximum extent, seek to minimize possible consequences, and ideally avoid casualties and destruction.
