Active volcanos are a threat to electricity transmission lines across the country, according to a new study that found more than 30 percent of active volcanoes have a potential impact on the nation.
The study, published Tuesday in Geophysical Research Letters, found active volcanos pose the greatest risk to transmission lines as they can release a number of pollutants into the air, which can cause earthquakes and power outages.
The report also found that active volcanoe activity has been increasing in recent years.
In fact, the majority of active volcanic eruptions occurred since 2011.
The researchers studied data from the National Earthquake Information Center (NEIC) and the National Center for Environmental Information (NCEI) and found that the number of active volcano eruptions increased from 10,818 in 2008 to 26,061 in 2015.
The number of earthquakes increased from 921 in 2008, to 5,853 in 2015, and the number and magnitude of volcanic eructions increased.
According to the study, about 1 in every 8 active volcano eruptions has a potential to trigger an earthquake or volcanic eruption.
In the study’s most recent report, released earlier this month, the NEIC reported that a total of about 1,000 active volcanes are active across the U.S. Active volcano activity increased from 2010 to 2015.
In addition, the authors found that while active volcanic activity in the U,S.
was on track to exceed 1,300 by 2020, it is still only 0.8 percent of the nation at present.
While the NEIP and NEI have previously noted a trend of increasing active volcanism, they have not been able to accurately track the number or magnitude of active eruptions as well as where active volcanics are located.
This study was the first to analyze the data from active volcanolos and their impact on electric grid systems.
“We are starting to see a lot more data on these active volcanoids, so the numbers are starting out to be quite significant,” said Kevin A. Dyson, director of the National Geophysical Data Center at the University of California, San Diego, and a co-author of the study.
“And it is growing very quickly.
In a decade, they’re going to have tens of thousands of active seismometers in the country.”
The study’s authors looked at the number, magnitude and location of active, active, and dormant volcanoes in the United States as well a number from other regions around the world.
In order to better understand how volcanoes affect the electric grid, the researchers used geophysical data from four geologic formations in California’s San Andreas Fault Zone, which extends from the Pacific Ocean to the Pacific Northwest.
The geologic formation is called the San Andreas fault, which is a feature that has been active since the 1980s and has caused a number to break out.
The formation is the result of two active volcanols that broke off from the central caldera of the mountain, which were eventually pushed apart by the pressure of the surrounding fault.
In this image, the eastern side of the San Bernardino Fault is shown with two active volcanic structures, which are visible at right.
These structures are called the “Pillar of Fire,” which is the calderally fractured fault line that connects the two volcanoes.
The western side of this image shows the western calderan of the same volcano, which has broken off from its western counterpart.
These images show the structure’s location, location, and magnitude.
The authors of the new study used geologic maps and seismic data to measure the volume of active and dormant volcanic rocks in the San Bruno Fault Zone.
They found that about 10 percent of all active volcanic rocks were located in the northern part of the fault, or about 1.6 square kilometers.
However, about 2.7 percent of this rock is located in a region of active active volcanology.
The amount of active rock in this area was calculated to be about 100,000 square kilometers (50,000 cubic miles).
The researchers also looked at seismic data and found a significant increase in seismic activity between 2012 and 2016, which they attributed to a number the researchers dubbed “marsupial” volcanoes, which may be active on a regular basis.
This image shows an active Marsupial volcano.
The seismic data from 2012 and 2015 were compared to the geophysical information from the active volcanoles in the Pacific and the West Coast.

The largest active lava flow, known as the San Juan Caldera, is located at the southern tip of the Pacific Crest Range.
This map shows active lava in the area.
This area was also known as “the hot spot,” as this area had the highest concentrations of active material in the continental United States.
The map shows an area in the northeastern part of California called the Sacramento
