GLOBAL VOLCANISM: The Volcano Report For March 30 To April 1, 2014 – Major Updates On Ubinas, Stromboli, Kilauea, Reventador, Karymsky, Krakatau, Yellowstone, Etna, Ibu, Sinabung And Poas! [PHOTOS+MAPS+VIDEO]

April 01, 2014 – WWORLDWIDE VOLCANOES – The following constitutes the new activity, unrest and ongoing reports of volcanoes across the globe.

Ubinas (Peru):  After several months of activity, Ubinas volcano has now erupted. The director of the Geophysical Institute of Arequipa, Orlando Macedo said that the eruption took place at 7:42 a.m. and gave off ash for one thousand meters.

A small explosive eruption took place earlier today, producing a plume of steam and ash that rose a few 100 meters.
As the new lava dome inside the volcano’s crater continues to grow, more and
possibly stronger explosions can be expected.

The volcano, in the south of Peru became active in September of last year, after having been dormant for several years. Nearby village, Querapi was set to be evacuated. The village is located just five kilometers from the volcano.

Macedo said that the villagers were affected by the ash that was emitted from the eruption. September 2013, when Ubinas became active after several years of dormancy, Peru21 reported that authorities were planning to permanently relocate Querapi. The village is located just four kilometers from the volcano.

“The wind has blown towards the south, to the residents of Querapi, four kilometers from the crater, and the district of Ubinas, located at six kilometers,” said Macedo.

The 20 families that lived in Querapi were evacuated to the locality of Ubinas last Saturday. They are waiting for the permanent removal of their village to Pampas de Hawái.

Ubinas volcano is considered to be the most active volcano of Peru. Eruptions have been reported since 1550.

Stromboli (Eolian Islands, Italy): Recently discovered dinosaur footprints in volcanic ash layers on a remote island volcano challenge the widely accepted theory that dinosaurs got extinct 65 million years ago.

Some of them might have survived for much longer.

Kilauea (Hawai’i): No significant changes in Kilaueas eruption activity over the past week – although the lava lake rose slightly to about 46m (151ft) below the floor of Halema`uma`u crater.

The northeast spatter cone complex continued to feed the Kahauale`a 2 lava flow, though this flow is still not legally or safely accessible. Smoke plumes from forest fires during the day and glowing spots at night confirm that the flow remains active on the East Rift Zone of Kilauea.

Karymsky (Kamchatka): The volcano remains more active than average. Another series of strombolian to vulcanian-type explosions today produced ash plumes rising to estimated 7,000 ft (2.1 km) and drifting SE (VAAC Tokyo).

Krakatau (Sunda Strait, Indonesia): New activity might have started at the volcano. An aircraft reported having sighted an ash plume from Anak Krakatau this afternoon at 10,000 ft (3 km) altitude.

On the other hand, VAAC Darwin who relayed the original report, mentioned that no ash plume could be detected on satellite data, and there is currently no hot spot on MODIS data. Whether or not a new eruption actually occurred at the volcano remains unclear, but would not be surprising at all.

Yellowstone (Wyoming, USA): A magnitude 4.8 earthquake at shallow 7 km depth occurred on Saturday morning with an epicenter located 4 miles north-northeast of Norris Geyser Basin in Yellowstone National Park. It was the largest quake since 1980 and occurred near the center of a region of recent ground uplift.

The event has sparked media reports that “Yellowstone might be erupting soon”,- however, while this event could be a precursor to new activity, it is far from likely that this will actually happen. In addition, the next eruption at Yellowstone if it is going to occur in a foreseeable future, is most likely going to be a small event (not a supervolcano eruption!).

USGS published the following press release:

PRESS RELEASE
University of Utah Seismograph Stations
Released: March 30, 2014 08:15 AM MDT

The University of Utah Seismograph Stations reports that a light earthquake occurred at 06:34 AM on March 30, 2014 (MDT). The epicenter of the magnitude 4.8 shock was located 4 miles north-northeast of Norris Geyser Basin in Yellowstone National Park, Wyoming. This earthquake is part of a series of earthquakes that began in this area on Thursday, March 27. As of 8:15 am today, this series has included at least 25 earthquakes in addition to the main shock, with the largest of magnitude 3.1. The magnitude 4.8 main shock was reported felt in Yellowstone National Park and in the towns of West
Yellowstone and Gardiner, Montana.

Anyone who felt the earthquake is encouraged to fill out a survey form on either the Seismograph stations web site: www.quake.utah.edu or the U.S. Geological Survey web site: earthquake.usgs.gov.

Today’s event is the largest earthquake at Yellowstone since February 22, 1980, and occurred near the center of a region of recent ground uplift described in a YVO Information Statement on February 18, 2014. The Yellowstone Volcano Observatory has been tracking this uplift episode for about 7 months.

As discussed in the March 3, 2014 YVO Monthly Update, seismicity in the general region of the uplift has been elevated for several months. A previous period of uplift in this area occurred between 1996 and 2003, and it was also accompanied by elevated seismicity.

A USGS field team is in Yellowstone and will visit the area near the earthquake’s epicenter today. The team will look for any surface changes that the earthquake may have caused, and for possible effects to the hydrothermal system at Norris Geyser Basin.

Based on the style and location of today’s earthquake, at this time YVO sees no indication of additional geologic activity other than continuing seismicity.

The Yellowstone Volcano Observatory (YVO) provides long-term monitoring of volcanic and earthquake activity in the Yellowstone National Park region. Yellowstone is the site of the largest and most diverse collection of natural thermal features in the world and the first National Park. YVO is one of the five USGS Volcano Observatories that monitor volcanoes within the United States for science and public safety.

Reventador (Ecuador): Activity at the volcano remains elevated, although no direct observations were possible in the last days due to cloud cover. A lava flow might be descending from the new dome on the eastern side, various reports suggests.

The observatory reported slight ash fall in the Hosteria

Reventador and the camp in San Rafael, both near the volcano. Noises from moderate explosions were heard.

Etna (Sicily, Italy): Since the end of lava effusion 3 days ago, Etna has remained all quiet and the recent flow field is now slowly cooling down.

Ibu (Halmahera, Indonesia): Activity (effusive / explosive) continues at the volcano, which has an active lava dome. A new MODIS hot spot is visible on satellite data, suggesting this has recently increased.

Sinabung (Sumatra, Indonesia): The volcano remains active on a slowly decreasing trend, with little variation over the past weeks. The viscous lava lobe remains weakly alimented and continues to grow very slowly.

An intermittent steam and sometimes light ash plume often rises up to about 14,000 ft (4.2 km) altitude.

No new pyroclastic flows have occurred recently.

Poas (Costa Rica): Another small phreatic eruption occurred from the volcano’s crater lake Friday morning.
