Japan raises volcanic alert at Mount Aso due to increased activity
The Japan Meteorological Agency (JMA) has raised the volcanic alert level this Friday for Mount Aso, located in the southwest of the country, after recording a notable increase in seismic activity over the last few days. The measure seeks to safeguard the population against the imminent risk of eruption.
Alert level and restrictions
The official body has set the alert at level three, on a scale of five. This classification implies an immediate ban on access to the mountain, due to the high probability of pyroclastic flows and the ejection of volcanic rocks within a two-kilometer radius around the crater.
Determining factors of the alert
- The uptick in tremors began to be detected since the afternoon of last Wednesday.
- Field analyses have confirmed a significant increase in the release of volcanic gases.
- The JMA maintains strict surveillance in light of the possibility of a short-term eruption.
In light of this situation, the Japanese Executive has proceeded to create a specialized information office to centralize data on the activity of Mount Aso, thus facilitating efficient coordination and communication between the various government agencies involved in the emergency.
Mount Aso, with an elevation of 1,600 meters, is a constant monitoring point located in Kumamoto Prefecture, specifically in a low-population density area within a national park on the island of Kyushu.
Japan, being located in the so-called Pacific Ring of Fire, has a complex volcanic geography. According to JMA records, the country is home to approximately 110 active volcanoes, defined as those that have experienced eruptions in the last 10,000 years or that currently exhibit fumarole emissions.
