The damage that can be caused by the high-risk volcano in the next decade



It came to California for many years, because they were "large", with a magnitude 6.7 or greater earthquake, it is expected to move from one state to another. But there is another deadly threat, that is, it is almost likely and people can do much less.

Within 30 years, in calculating the eruption of small and medium-sized eruptions, there are 16 points in a damaged area, U.S. According to the Geological Survey (USGS), on Monday (February 25). This forecast is based on 5,000 years of volcanic activity records. They live or work around 200,000 people in the region where they are in an eruption, and they visit millions every year, according to the report.

By contrast, a 22-percent chance is that the earthquakes of San Andres Fault, sometimes known as "large ones", will remain within this period of time.

"Damage to earthquakes, floods, floods, tsunamis and forest devastations are well known", the researchers wrote in the report. "The eruptions of the rings are not the same, as it is one of the greatest earthquakes in the San Andres Fault".

There are systems to detect potential potential eruptions, but understanding the risks of specific parts of this situation is important to minimize the damage and loss of these events.

There are eight volcanic areas in which people say "threatening" people or nearby goods, according to the report. At least eight volcanoes are seated on seven magma and considered as "active". [Countdown: History’s Most Destructive Volcanoes]

From them, Mount Shasta, from the Lake Medicine Lake and the Lassen Volcanic Center in northern California; and Salton Buttes, close to the southern border, have fallen in the last 3000 years and are very dangerous areas. Eastern Long Valley Eastern Volcano Region has also been an eruption at that time, but it is very dangerous. And the northern part of the Clear Lake Volcanic Field in San Francisco is also very dangerous, although it has been the last three million explosions.

A volcano can cause serious damage, although there is no eruption, according to the report. Falling volcanoes can cause beacons of many rocks, currents or rapid lava currents are called pyroclastic currents and acid rain. However, volcanic eruptions that are not present can cause dangers. Volatile causes may be more insecure and may cause landslides.

Although these operations are felt next to the eruption, floods or floods reach more than 50 kilometers (80 kilometers), and ashfalls can reach 1,000 miles (1,600 km), according to the report.

"Volcanic risks are likely to have more than one local problem, limited to a single region or region," said the report. "The future eruption of northern California, for example, the natural resources and infrastructure that could be important for water, power and transport systems in our country, could be negative and undoubtedly require a multidisciplinary response." Eruption itself may take longer or longer intensities over the course of months, years or decades, as it may have consequences.

Rings of the rings can not be prevented, they can sometimes be predicted.

The USGS California Volcano Observatory uses GPS receivers to record deformations of soil, measure seismometers and detect spectrometers for groundwater detection. If any of these three measurements increases, the volcano may be the first sign that climbs up, according to the report.

"Although eruptions can not be stopped, measures to limit exposure and tolerance to society can less harm their consequences," they wrote. This implies the elimination of risk areas during the eruption, which respects the effects of the infrastructure, after the event has been cleared and the deviation of the lava or the removal of materials. In the case of ashes, people can wear particle masks, avoid driving, avoid building, shelter shelter and shelter.
