New Ash Emissions At Turrialba Volcano In Costa Rica

Current seismic signal of Turrialba volcano (VTUN station)
A new phase of ash emissions seems to be in progress at the volcano (which itself has been in clouds, preventing direct observations). 
 
Starting 11:58 local time, an increase of tremor was noted and later on, ash fall has been noted in nearby downwind areas (to the NE).

Very Powerful Explosions With Ash Plumes 3-4 km Tall At Santiaguito Volcano In Guatemala

The activity at the Caliente lava dome remains very elevated: a series of 3 powerful explosions occurred this morning (around 07:45 local time), yesterday evening (17:45) and Saturday morning. 
 
The eruptions produced ash plumes that rose 3-4 km above the dome and multiple pyroclastic flows that traveled up to 2 m length mainly on its southern and eastern sides. Moderate to heavy ash fall occurred in areas south-west of the dome complex, including the towns and villages of Nuevo Palmar, San Felipe Retalhuleu, Aldea Loma Linda, San Marcos Palajunoj El Patrocinio and others. 
 
According to INSIVUMEH, the explosion sounds could be heard up to 30 km away and ballistic ejecta (blocks and volcanic bombs) landed in up to 3 km distance. The current phase of activity has been the highest recorded at the volcano since at least 2 years.

Two small to moderately sized pyroclastic flows occurred this morning at the volcano. 
 
The larger one at 06:16 local time (image) produced a pyroclastic flow that traveled 2700 m on the SE side and a co-ignimbrite ash plume that rose 2500 m into the sky.

A series of small quakes have occurred at Mount Hood, Oregon, USA

Mount Hood is a potentially active stratovolcano in the Cascade Volcanic Arc of northern Oregon. It was formed by a subduction zone on the Pacific coast and rests in the Pacific Northwest region of the United States. It is located about 50 miles (80 km) east-southeast of Portland, on the border between Clackamas and Hood River counties. In addition to being Oregon’s highest mountain, it is one of the loftiest mountains in the nation based on its prominence.
 
The height assigned to Mount Hood’s snow-covered peak has varied over its history. Modern sources point to three different heights: 11,249 feet (3,429 m), a 1991 adjustment of a 1986 measurement by the U.S. National Geodetic Survey (NGS),[1] 11,240 feet (3,426 m) based on a 1993 scientific expedition,[6] and 11,239 feet (3,426 m)[7] of slightly older origin. The peak is home to 12 named glaciers and snowfields. It is the highest point in Oregon and the fourth highest in the Cascade Range.[8] Mount Hood is considered the Oregon volcano most likely to erupt,[9] though based on its history, an explosive eruption is unlikely. Still, the odds of an eruption in the next 30 years are estimated at between 3 and 7 percent, so the U.S. Geological Survey (USGS) characterizes it as “potentially active”, but the mountain is informally considered dormant.

I have tweeted USGS & EMSC the importance of the sudden quakes in the Mount Hood area and must take this seriously as a precaution
