Tolbachik (Kamchatka): There are no signs of the eruption ending soon. Although an overall weakly decreasing trend is visible over the past months, tremor levels reported by KVERT remained stable during the past week and lava continues to be erupted form the southern fissure, feeding a vast flow field mainly SE of the volcano.

Sakurajima (Kyushu, Japan): Activity remains elevated. During most of the time, the volcano produces (usually silent) near-continuous ash puffs that reach varying heights of a few hundred meters, as well as intermittent vulcanian explosions with plume heights often exceeding 3 km. Often, the plumes from this activity merge into a continuous one that has been drifting into easterly directions where light to moderate ash fall occurs.
The eastern sector of the volcano is covered by up to several cm of fresh ash from the activity during the recent weeks.

Merapi (Central Java): A small explosive eruption occurred from the volcano yesterday (22 July) morning between 04:22 and 05:35 local time. It produced a dark ash plume rising about 1000 m and ash fall in the villages of Klaten (SE of the volcano) and Sleman (SW).

White Island (New Zealand): The "drumbeat" earthquake activity, which could be caused by pulsating steam and gas emissions from a narrow conduit continues. Over the past days, the intensity of seismic activity has risen, but dropped again a bit at the moment.

Veniaminof (Alaska Peninsula, USA): AVO reports no changes in activity: continuous low-level volcanic tremor, elevated surface temperatures at the intracaldera cone, visible glow and low-level ash and steam plumes indicate that lava flows continue to be erupted, along with mild strombolian activity.

Popocatépetl (Central Mexico): Activity has been low during the past days. Emissions of steam, gas and only sometimes small amounts of ash occurred at rates fluctuating between 0-3 per hour and plumes reached a maximum of about 1 km above the crater.

Turrialba (Costa Rica): The seismic crisis continues with a swarm of volcanic-tectonic quakes as well as periods of low-frequency tremor and possible small explosion signals (which could suggest small phreatic eruptions). OVSICORI wrote that on 18 July, over 1000 earthquakes were recorded on a single day.

Reventador (Ecuador): Small to moderate explosions and (probably) the effusion of a lava flow on the NE side of the cone continue. Seismic activity is high.

Tungurahua (Ecuador): Activity remains high. The volcano produces intermittent explosions and near continuous strombolian explosions and ash emissions that produce an eruption column reaching up to 1.5 km above the crater. Easterly winds drift the ash mainly to the west and SE, where light ash fall occurred in Cahuají and Choglontus.
