Did The Earth Move For You, Or Was It Just Steam?

Now I don’t know

The Japan Meteorological Agency has issued a bulletin on a volcanic eruption in Kumamoto Prefecture, southwestern Japan.

The agency says Mount Aso erupted around 11:43 a.m. on Wednesday. Officials are now evaluating the eruption.

They are urging people in the volcano’s vicinity to secure their safety and keep abreast of the latest information.

An eruption bulletin is issued when a larger explosion occurs at a volcano that has previously erupted.

Expert: Mt. Aso likely a steam eruption

Friday, Oct. 22, 10:00

An expert says analysis of volcanic ash from Mount Aso in western Japan found no substances related to fresh magma from underground, indicating the blast on Wednesday was probably a steam eruption.

The National Institute of Advanced Industrial Science and Technology, or AIST, analyzed volcanic ash collected in Takamori Town, 4.2 kilometers southeast of a crater that erupted.

The institute says the analysis found that almost all of the ashes consisted of pieces of rocks from around the crater and that no substances from magma deep underground were confirmed.

The institute says the finding shows heated underground water caused Wednesday’s eruption, and that the volcano is unlikely to erupt on a major scale soon.

Yamamoto Takahiro, deputy chief of AIST’s Research Institute of Earthquake and Volcano Geology, says steam eruptions gradually shifted to magma eruptions in the volcano’s activities in the past.

Yamamoto said the volcano is continuing its active activities and there’s no doubt that magma exists underground. He added that further monitoring is necessary to see if the ratio of magmatic materials will increase.
