The satellites detected on the 18th, and especially on 19th April 2017, a thermal anomaly on Nishinoshima.
In the afternoon of April 20, an observation by the Japan Coast Guard confirms a white plume and the presence of lava flowing from the crater on the flanks of the cone.
The JMA / Japan Meteorological Agency announced a warning notice at 16:25, with a ban on entering the island and within a 1.5-km radius of the crater. A navigation alert was issued to vessels cruising nearby.


 

Nishinoshima - Sankei news - Added 20 Apr 2017

Professor Kenji Nogami of the Tokyo Institute of Technology confirmed the resumption of the activity after examining the images taken by the Coast Guard: "... because the lava leaves vigorously from the crater, it seems that a large quantity of magma fed from below, and if the eruption continues, the lava can reach the coast and cover part of the island ... "
Volcanologist Setsuya Nakada of the University of Tokyo added that "the level of volcanic activity of Nishinoshima is practically the same as that observed in 2014 when the volcano was active."
