Merapi: Seismic drops off

MerapiSeismicity on Merapi has dropped sharply in the last two days. It halved from almost 400 daily quakes to less than 200 tremors. That still sounds like a lot, however, these are almost all rockfall signals that are being registered. Hybrid and volcanotectonic quakes were hardly detected. Just these quakes are caused by rising magma. So it could be that the magma ascent stopped and the current dome growth phase ends. The next few days will show whether the volcano is only taking a short breather or whether it will actually take a longer break.
