One of the scientific topics that fascinates me most concerns volcanism in North America. When I was a geology student I loved exploring this topic, and, like yestrerday, on Rapusia Blog we have already covered related topics.

The United States of America is a country rich in natural resources, and one of these resources is the presence of numerous active volcanoes. While many of these volcanoes are little known or do not pose much of a risk to the surrounding population, there are some volcanic areas that are considered among the most dangerous in the country.

One of the most well-known and dangerous volcanoes in the United States is undoubtedly Mount St. Helens in Washington state. Mount St. Helens is known for the catastrophic eruption that occurred in 1980, resulting in the deaths of 57 people.

The volcano is monitored extensively by the United States Geological Survey (USGS) through a network of monitoring instruments that measure gas pressure, ground deformation, and seismic activity. Additionally, aerial surveillance is carried out to view volcanic activity and identify any changes in the shape of the volcano.

Another active volcano that requires close surveillance is Hawaii Volcanoes National Park. This park, which includes the Kilauea and Mauna Loa volcanoes, is one of the islands' most popular tourist attractions. However, the volcanoes present here are considered dangerous due to frequent eruptions.

Kilauea is one of the most active volcanoes in the world and has seen numerous eruptions over the years. Mauna Loa, on the other hand, is the largest volcano in the world in terms of volume, but its last eruption dates back to 1984.

Both volcanoes are constantly monitored through monitoring instruments similar to those used for Mount St. Helens. In Alaska, however, there are several active volcanoes that require intensive surveillance. Among the most dangerous volcanoes in this region are Mount Redoubt, Mount Spurr, and the Aleutian Islands Volcano.

These volcanoes are monitored closely by the Alaska Volcano Observatory (AVO). The AVO observation network includes instruments for seismic monitoring, gas measurement, ground deformation and visual surveillance through telescopes and webcams.

In addition to the specific volcanoes mentioned above, the United States has many other active volcanoes that require constant attention. Some of these include Mount Rainier in Washington state, Yellowstone Volcano in Wyoming, Mount Shasta, and the Cascade chain of volcanoes in the Pacific Northwest.

All of these volcanoes are monitored by geologists and scientists working for the USGS and other scientific institutions. Surveillance of volcanoes in the United States is crucial to ensuring the safety of people who may be in the surrounding areas.

The data collected by various monitoring tools allows geologists to identify early signs of an impending eruption, allowing authorities to evacuate risk areas and take other necessary safety measures. Thanks to constant surveillance by agencies such as the USGS and AVO, these volcanoes are carefully monitored to ensure the safety of the population.
