According to news reports, on 6 February University of Colima staff flew over Colima and observed lava flows travelling down the volcano's S flank. On 9 February two pyroclastic flows occurred. The Universidad de Colima reported on 30 January that the growing lava dome at Colima could result in either a dome collapse in days or weeks that would send pyroclastic flows down the volcano's S flank, or explosions could destroy the lava dome and hurl volcanic fragments several kilometers.
Several incandescent landslides were seen traveling less than 1 km down the S and SSW flanks of the volcano. During a flight over the volcano, members of the Advisory Scientific Committee noticed that dome growth occurred towards the W.
Seismicity was relatively low; numerous earthquakes with very low magnitudes occurred.
