3 Volcanoes in 24 Hours


At least 26 eruptions accompanied by steam and gas, as well as a volcano tectonic quake were registered as a consequence of the Mexican volcano Popocatépetl activity during the last hours, it was reported Tuesday. The National Center of Disaster Prevention (Cenapred) said eruptions were of low and medium intensity with no ash expulsion in any of them. According to the institution, the volcano tectonic quake was registered at 11.54 local time (16:54 GMT). At this moment, the alert light of volcano activity remains yellow phase 2 and the surrounding population to keep informed as to alerts on the activity of the volcano also known as Don Goyo. Traffic between Santiago Xalitzintla and San Pedro Nexapa, via the Cortes passage, is under control. The Popo is located at the center of the country, in the territorial limits of the Morelos, Puebla and Mexico states. Located 55 kilometers Southeast of the Federal District, the Popocatépetl is the second highest volcano in Mexico, with a maximum height of five thousand 458 meters above sea level, only second to the Pico de Orizaba (Veracruz) with five thousand 610 meters.

A volcano has erupted on Indonesia’s Sumatra island, spewing thick grey smoke up to 1.5 kilometres into the sky. Monitoring official Suparno says Mount Marapi’s eruption on Wednesday is its strongest since August last year, when its status was raised to level three out of four. Suparno, who uses one name, says there is no plan for an evacuation because the nearest villages are far beyond the danger zone of three kilometres from the crater.

A volcano on the border of China and North Korea is showing signs of increasing activity and could erupt in the next few decades, Chinese researchers say. A massive eruption of Changbaishan around 1,100 years ago spread ash and volcanic gases for 30 miles and left a 3-mile-wide crater atop the volcano, scientists said. Three smaller eruptions have occurred since then, the most recent in 1903, they said. Seismic activity, ground deformation and gas emissions recorded in a period of heightened activity from 2002 to 2006 suggests the magma chamber beneath the volcano is growing. This activity suggests an explosion could occur in the next couple of decades, researchers said. “We need to upgrade our current monitoring system in order to be able to meet the need for the early warning system for Changbaishan,” Jiandong Xu, a vulcanologist at the China Earthquake Administration in Beijing. Of the dozen or so volcanoes located in mainland China Changbaishan is the most likely to experience an eruption with potential catastrophic effects, Xu said.
