There are concerns this activity is leading up to something much bigger or that they could cause a structural failure and collapse of the volcano its self. Almost 10,000 people have been displaced by the activity however some officials fear that only a third of residents have left the area voluntarily putting thousands at risk if activity does worsen. The pyroclastic flows have reached at their furthers, 2.5 km from the summit on the southeastern flank.
Asama has added to the list of Japanese volcanoes which have been disrupting life in the country on Tuesday 16th .

As a precaution a 2km exclusion zone has been put in place. The alert level has remained on 2.
Tuesday 16th also renewed activity on Bulusan with 2 small phreatic eruptions occurring in the morning creating a kilometer high white plume. Although this was accompanied by the sound of rumbling from within, the alert has remained at 1 but a closer eye is being kept on the mountain for any other signs of activity.
