The US Geological Survey says some US volcanoes are at risk of erupting

The US Geological Survey has published a code orange and watch alert for one volcano and a code yellow and advisory alert for six volcanoes tracked across the country. The USGS says these volcanoes "show signs of increasing disturbances above the known background level." The volcano with the highest alert symbol is Great Sitkin in Alaska; Just days ago, the Alaska Volcano Observatory (AVO) raised its color and alert signs to Orange and Watch. The six with a Yellow/Advisory High Alert Level include the world's largest active volcano, Mauna Loa, Kilauea, Gareloi, Semisopochnoi, and Cleveland. While Mauna Loa and Kilauea are located on the Big Island of Hawaii, the rest are located under the Yellow Code in Alaska.

Within the United States, theUS Geological Survey tracks 169 active volcanoes, most of them in Alaska. However, Alaska is home to many volcanoes; over 130 volcanoes and volcanic fields have been involved in the geological age during the past two million years. Fifty have been active since the mid-18th century, and AVO has studied these as well. Another place famous for its volcanoes in Hawaii. In addition to other cities Kilauea, Mauna Loa, and Hualalai are active and potential threats, yet none have erupted. Kilauea started a new eruption in December 2020, but that eruption ended just weeks ago. Hawaii's volcanoes are monitored by the Hawaiian Volcano Observatory (HVO).

In contrast, the Alaskan volcanoes are monitored by the Alaska Volcano Observatory (AVO.) and the California Volcano Observatory, the Cascades Volcano Observatory, and the California Volcano Observatory. Yellowstone Volcano Observatory. Each of those additional volcanic observatories within the USGS monitor volcanoes in their areas. None of those other observatories have reported unusual activity or signs of anything more than background noise at the moment.

According to (USGS), about 1,500 potentially active volcanoes worldwide, with 500 out of 1,500 erupting in historical times. Most of the world's volcanoes are located around the "Ring of Fire" around the edge of the Pacific Ocean. There is a fire around the edge of the Pacific Ocean where many volcanic eruptions and earthquakes occur. Due to the movement of the lithosphere, plates under and around the Pacific Ocean move, collide and destroy, resulting in the seismic activity for the Ring of Fire is famous.
