The Global Volcanism Program (GVP) seeks better understanding of all volcanoes through documenting their eruptions--small as well as large--during the past 10,000 years. RSAM data values notably increased during the morning of 1 March, reflecting an increase in Strombolian activity. Heavy rains fell for about an hour on Saturday, washing away vehicles. Such activity can include, but is not restricted to, pyroclastic flows, lahars, lava flows, dome collapse, or increased unrest. An eruption plume rose as high as 11 km a.s.l. Once a volcano is included in the "New Activity/Unrest" section, updates will remain in that section unless the activity continues for more than 1 month without escalating, after which time updates will be listed in the "Continuing Activity" section.

INSIVUMEH and CONRED reported that during 23-25 February explosions at Pacayaâs Mackenney Crater ejected incandescent material as high as 200 m. A lava flow, originating from a vent 300 m below the summit crater, was about 1.1 km long and produced incandescent blocks from the flow front that descended 300 m. more intense pulses of activity at the summit produced dense ash plumes that drifted more than 30 km S and SW. Ashfall was noted in areas downwind including Los Pocitos, Pacaya, El Rodeo, and El Patrocinio. Incandescent material was ejected 150 m high, and ash plumes drifted W; ashfall was reported in El Patrocinio. Strombolian activity at two vents in SEC increased during the late afternoon of 24 February. Moreover, Earth's sea-floor volcanism is seldom reported even though in theory it represents the single most prolific source of erupted material. No comments yet. No other observation data showed signs of unrest. PVMBG reported that daily gray ash plumes rose 200-1,200 m above Raungâs summit during 24 February-2 March.

The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km exclusion zone. After 5 impressive paroxysms, the activity at the volcano intensified again at 19:00 UTC on February 24 and evolved into another spectacular event. The highest volcano is Mount Semeru, at 12,060 feet (3,676 metres). Volcanoes are included in the "New Activity/Unrest" section of the Weekly Volcanic Activity Report if the activity occurs after at least 3 months of quiescence.
