Philippines – A tornado in Banga town in South Cotabato province in the Philippines has destroyed at least eight houses. The tornado also caused power outage in the area.

China – The death toll in China’s latest round of flooding has risen to at least 57, including two schoolchildren aboard a bus carrying more than twice its authorized passenger load that plunged into a pond, authorities said Saturday. At least 13 other people are missing in floods that have ravaged mountain districts of six provinces and autonomous regions in central and southeastern China. More than a quarter-million people have been moved to temporary shelters, and major damage has been inflicted on buildings and crops. Among the dead were 16 people killed in the collapse of a nine-story building in the city of Guiyang following a landslide.

Nepal – A landslide in Suri VDC-2 in the Dolakha district in Nepal has claimed the life of an elderly man. The April 25 earthquake has weakened the land structure in the area, making it more prone to landslides.

Nepal – Another landslide at Ramche-9, Kafaldada has blocked the Kaligandaki riverblocking the water flow and creating a two kilometre long lake. Local residents have been placed on high alert. Thousands have fled the area.

Nepal – A sandstorm in Kathmandu, Nepal temporarily closed the Tribhuvan International Airport (TIA). Strong winds gusting with a maximum speed close to 80 km/hr hit Kathmandu valley Saturday evening. One person died in a wind related accident.

Roundup of Global Volcanic Activity

Shiveluch (Kamchatka): KVERT reported that during 8-15 May lava-dome extrusion onto Sheveluch’s N flank was accompanied by incandescence, hot block avalanches, and fumarolic activity. A daily thermal anomaly was also detected in satellite images. The Aviation Color Code remained at Orange.

Sinabung (Sumatra, Indonesia): The eruption continues with no significant changes. Viscous magma effuses slowly from the summit vent and continues to grow a new lava lobe on the upper southern flank. Collapses of parts of this unstable lava mass generate small to moderate pyroclastic flows.

Ambrym (Vanuatu): Activity at the volcano remains elevated. Lava lakes are active in Bembow and Marum craters. Geohazards maintains volcanic Alert Level 2: “The danger remains in the caldera area around the volcanic craters of Benbow and Marum (including Maben-Mbwelesu, Niri-Mbwelesu and Mbwelesu) and on volcanic ash and gas prone areas exposed to trade winds.”

Colima (Western Mexico): Explosions continue to occur from time to time. On 16 May an ash plume rose from Colima to an altitude of 5.5 km (18,000 ft) a.s.l. and drifted 95 km ESE before dissipating. A new lava dome might have started to grow inside the summit crater, where a flat, elevated ash-covered area is visible on a recent aerial photo.

Ubinas (Peru): Activity remains low at the volcano. No explosions have occurred recently, only mild to moderate steam emissions, sometimes mixed with light ash, reaching up to 1-1.2 km height and drifting mainly east and northeast. On the other hand, SO2 emissions were elevated and seismic activity, in particular rock-fracturing earthquakes, picked up a bit during the past week. This suggests that the internal pressure has increased compared to earlier this month.
