With the opening another fissures, released sulfur dioxide (SO2) emissions from the lava flows and cones have increased and caused heavy gas pollution detected around the eruptions sites.
Scientists warn people about opening a new fissures with little to no warning in the next few days or weeks that could pose an acute danger to people. An attached map shows a danger (red line) area where a new lava flows suddenly could start to erupt that is difficult to avoid. This indicates that the flux of magma is located at shallow level and pushes its way up to the surface.
