In recent days, several volcanoes considered among the most active in the world have led to heightened alerts and updated protocols in different parts of the world. The recent events at Popocatépetl in Mexico, Kilauea in Hawaii, and Lewotobi in Indonesia They underline the importance of constant monitoring and the adaptation of new technologies for the prevention and protection of nearby communities.
Active volcanoes have always been a source of attention due to the risk they represent. both for the population and for air traffic and the environment. The latest eruptions and episodes of activity remind us that these natural giants They can change their behavior suddenly, which requires continued vigilance and caution in the face of any sign of increased activity.
Popocatépetl: 26 recent exhalations and reinforced monitoring in Mexico
The Popocatépetl volcano, known locally as Don Goyo, recorded 26 exhalations in just 24 hours, according to the report of the National Center for Disaster Prevention (Cenapred) and UNAM. The alert level is currently maintained at yellow phase 2., which implies specific restrictions and the recommendation to keep the population away from the crater due to the risk of ballistic fragments.
Among the preventive measures, It is advisable to avoid nearby ravines Due to the possibility of lahars and mudflows following heavy rains, a hotline established by Cenapred (National Commission for the Prevention of Torture and Reduction of Torture) is available to answer questions and report emergencies. Popocatépetl monitoring includes seismographs, specialized cameras, and volcanic gas analysis—key tools that allow for anticipating potential eruptions and making informed decisions for public safety.
Kilauea: Lava spectacle in Hawaii under close observation
El Kilauea volcano, considered one of the most active on the planet, erupted recently in Hawaii and generated lava fountains that exceeded Meters 300These emissions began after a slight increase in seismic activity that was detected by the United States Geological Survey (USGS) and led to a notable nocturnal eruption, causing no casualties or damage to homes, since The phenomenon is concentrated in restricted areas of the Volcanoes National Park.
Currently, although the activity is under control and there are no immediate risks to the population, The aviation alert remains at orange level due to the presence of ash in the atmosphere and the possibility of sudden changes in eruptive behavior. Authorities maintain continuous monitoring using cameras, sensors, and aerial surveillance to assess any changes.
Lewotobi: Emergency in Indonesia due to ash columns
In turn, the Lewotobi Laki-Laki, on the island of Flores (Indonesia), has been the protagonist of recurrent episodes of eruptive activity in recent weeksThe most recent eruption raised ashes to more than 10 kilometers high, which led Indonesian authorities to declare maximum alert (level IV) and restrict activity within a radius of up to seven kilometers around the crater.
The authorities have recommended to the population do not approach the danger zone and protect yourself from falling ash by wearing masks, as well as being alert to possible mudflows, known as lahars, especially after heavy rains. Among recent events, this volcano has caused flight cancellations to tourist destinations and, in previous episodes, has caused fatalities and mass evacuations. Indonesia is in the midst of Pacific Ring of Fire and has more than 120 active volcanoes, making management and monitoring challenges of enormous magnitude for the country.
New technologies to anticipate volcanic activity
In recent years, The prediction of volcanic eruptions has made important strides thanks to the use of advanced technology.In addition to seismic and visual monitoring systems, Innovative methods such as satellite observation of changes in vegetation near volcanoes are being implemented.Recent research coordinated by NASA and the Smithsonian has discovered that Trees located near active volcanoes may experience physiological changes before an eruption, detectable from space by the increase in greenness in their crowns due to the presence of carbon dioxide emitted by the rise of magma.
The use of satellite imagery and optical sensors allows surveillance coverage to be extended to hard-to-reach areas and minimizes the exposure of technical personnel to hazardous environments. However, this method It has limitations, since not all volcanoes are surrounded by vegetation, and external factors can influence plant response. Therefore, The combination of classical and modern techniques remains key in the prediction and management of volcanic risk.
Recent events in the Americas, Asia, and the Pacific make it clear that volcanic activity remains very present and active. Improved warning systems and advances in scientific research are allowing the public and authorities to face these phenomena with greater preparation and less uncertainty, reducing risks and learning more about the unpredictable behavior of active volcanoes.
