Raung (East Java): Activity has decreased at the volcano. During the past days, the ash plume was much lower and only extended several tens of kilometers in southerly directions.
Heat emission remains significant, but has also decreased a lot compared to the previous week.

Sinabung (Sumatra, Indonesia): According to a news article in the Indonesian press, volcanologists monitoring Sinabung believe that magma supply to the growing lava dome has recently increased.
This will likely result in more and larger pyroclastic flows that can threaten a number of villages that so far have been unharmed. These include Pasarpinter Gurkinayan, Simpang Sibintun, Perjumaan Batukejan, Jembatan Lau Benuken Tigapancur, Pejuman Tigabogor, Pentumbes, Jeraya, and Kutatengah on the SE slope.

Dukono (Halmahera): The volcano continues to produce near-continuous ash clouds that reached a length of approx. 100 km towards the west this morning.

Colima (Western Mexico): Explosions remain frequent and sometimes intense. Ash columns rise up to 2 km from the crater.
Check out the following tweet showing a comparison of the crater between 11 Mar and 8 July - the lava dome and parts of the crater rim have disappeared:
