Peru – Two more people have been killed in a landslide in Peru, bringing to at least 50 the number of people who have died since the rainy season started in September, according to the Centre for National Emergency Operations. The landslide was triggered by torrential rain in the city of Huancavelica, where hospitals and schools have been inundated, and severe flooding has blocked roads and damaged bridges, the centre said. Thousands of families have been affected by the flood waters, with many calling on the government to do more to alleviate the situation.

California, USA – Rivers swollen by days of heavy rain inundated portions of northern California on Wednesday, forcing hundreds of people to flee their homes. However, about half of the 4,000 people ordered to leave have refused to do so. Two towns – Guerneville and Monte Rio – were islands surrounded by water, local officials said. The only way to reach the two communities now is by boat.

Wildfires

Wildfires – UK

Firefighters have contained a blaze that erupted on moorland in West Yorkshire in northern England, one of the three wildfires that broke out across the United Kingdom as temperatures hit record seasonal highs. The fire, on Saddleworth Moor, burned throughout Tuesday night across about 1.5 square kilometers (370 acres) near the village of Marsden.

Other fires broke out in Edinburgh, on the city’s famed Arthur’s Seat hill, and in the southern English county of West Sussex, in woodland immortalized by A.A. Milne’s Winnie the Pooh stories.

Swimming in the open ocean entangled this loggerhead sea turtle (Caretta caretta) in a dangerous trap posed by a discarded fishing net. Luckily, photographer Eduardo Acevedo encountered the turtle near the Canary Islands, and released her from the net after capturing this striking image.

Volcanos

Global Volcanic Activity – New Activity for the week of 20 February – 26 February 2019

Bezymianny | Central Kamchatka (Russia) : On 27 February KVERT reported increased activity at Bezymianny characterized by nighttime crater incandescence, hot avalanches originating from the lava dome, and occasionally strong fumarolic activity. The report noted that the temperature of the thermal anomaly was gradually increasing. The Aviation colour Code was raised to Orange (the second highest level on a four-colour scale).

Karangetang | Siau Island (Indonesia) : PVMBG reported that during 20-26 February dense white plumes rose as high as 500 m above the rims of Karangetang’s Main Crater and Kawah Dua (North Crater). The Alert Level remained at 3 (on a scale of 1-4), and residents were warned to remain outside of the 2.5-km exclusion zone around the N and S craters, and additionally within 3 km WNW and 4 km NW.

Karymsky | Eastern Kamchatka (Russia) : KVERT reported that ash plumes from Karymsky were identified in satellite images drifting 200 km E during 16-20 February, and a thermal anomaly was visible during 16 and 18-20 February. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Piton de la Fournaise | Reunion Island (France) : OVPF reported that activity continued during 20-26 February from the fissure that opened on 19 February; the site is at 1,800 m elevation at the foot of Piton Madoré, E of Piton de la Fournaise’s Dolomieu Crater. On 21 February scientists mapped the slowly eastward-advancing flows (and also those that had erupted on 18 February). They noted that the cone at the vent was growing, and hosted a lava lake that ejected spatter from bursting gas bubbles. A channelized lava flow traveled 1 km E and descended 200 m elevation before splitting into two flows near Guyanin Crater. The more northern of the two flows was 50 m wide and had progressed as far as 1,320 m elevation. The second more southerly flow was 200 m wide and itself split into two flows about 300 m SE of Guyanin Crater; one branch went to about 1,350 m elevation and the other to 1,300 m. Overall the longest part of the lava flow had traveled 1.9 km from the vent. During 22-26 February the lava emission rate was variable up to 16 cubic meters per second (based on satellite data), though webcam images from 24 February indicated that the flow had not significantly advanced.

Poas | Costa Rica : OVSICORI-UNA reported that during 23-26 February seismicity at Poás was dominated by low-frequency events. Robust gas emissions rose from four fumarolic vents in the area previously covered by a lake, though the most vigorous emissions originated from vent A (Boca Roja). Minor incandescence from vent A was sometimes visible at night. A sulfur odor was reported in areas downwind including Naranjo, Zarcero, and Grecia (16 km SW). Particles of molten sulfur were included in ash deposits collected in Naranjo. Ashfall was reported in Canoas de Alajuela on 26 February.

Semeru | Eastern Java (Indonesia) : Based on analysis of satellite images, the Darwin VAAC reported that on 24 February an ash plume from Semeru rose to an altitude of 4.3 km (14,000 ft) a.s.l. and drifted W.
