The Tokyo Volcanic Ash Advisory Center has issued an alert for a “possible eruption” for the volcano in the Philippines. It follows images taken by the Japanese satellite HIMAWARI-8. Sharing the report on Twitter, extreme weather hunter James Reynolds said: “Tokyo VAAC has volcanic ash alert in Pinatubo.”
To which meteorologist Kyle NoÃ«l replied: “Yes, it’s suspicious volcanic activity taking place at Mount Pinatubo.
Mr. Noel shared an image of the Himawari-8.
He later replied that he thought it was “a convection created by mountain rise rather than a volcanic eruption“.
He noted: âThere was a ripple of clouds moving across these mountains.
“Sloping / orographic uplift could explain a sudden explosion of convection in this area rather than a volcanic eruption.
“Some reasons to doubt the alert, the absence of earthquakes from the seismographs and the lack of local reports.
“Can someone on the ground confirm if there was an eruption?”
And the Pinatubo Volcano Advisory later confirmed that a “weak explosion” had occurred.
They tweeted: âThe Pinatubo volcano network recorded seismic and infrasound signals from a weak explosion at Mount Pinatubo between 12:09 and 12:13.
âThe event produced a plume which was detected by the Himawari-8 satellite and reported by the Tokyo Volcanic Ash Advisory Center.
“Seismic and infrasound signals are not typical of known volcanic processes and are currently being evaluated with other potential sources.
“There has been very little seismic activity in recent days and the geochemical wind from Crater Lake Pinatubo in November produced a weak flux of diffuse volcanic CO2.”
They told the public to stay away from the area and from local government units to “ban entry into the crater” until the source of the “explosion” is known.
Located in the central Luzon region of the Philippines, Pinatubo erupted three decades ago.
Its 1991 eruption was considered by the US Geological Survey to be the second largest volcanic eruption of the 20th century.
The effects of the rash were felt around the world.
It ejected around 10 billion tonnes of magma and 20 million tonnes of sulfur, bringing large amounts of toxic minerals and metals to the surface of the environment.
It injected more particles into the stratosphere than any eruption since Krakatoa in 1883.
Over the following months, the aerosols formed an overall layer of sulfuric acid haze.
Global temperatures have dropped by about 0.5 Â° C.
