Strong earthquake Mw 7.6 shakes Loyalty Islands

The Loyalty Islands region has just been shaken (13:19:57 UTC) by a strong earthquake of magnitude 7.6. The epicenter was located 401 km east of Tadine on New Caledonia. The earthquake focus was located at a depth of only 2 km. Should the information be confirmed, then in my opinion a tsunami is imminent. The strong earthquake was preceded by several quakes with magnitudes between 6.2 and 5.7.

Semeru: Lahar swept away car

A lahar formed at the Javanese volcano Semeru the day before yesterday. The mud flow swept away a car and sank it in a riverbed near the village of Supiturang. The parked car was on a small path at the edge of the river and was loaded with diesel for mining machinery. The driver was in the sand mine on the slope of the volcano and remained uninjured. However, the fuel is believed to have been released and is polluting the environment. Sand mines are found at many volcanoes in Indonesia. Here volcanic sand is extracted, but also gravel for road construction.

Lahars are formed when water (usually as a result of heavy rainfall) mobilizes volcanic deposits on the slope.

Semeru has been particularly active again since early February. The VSI registers about 80 seismic eruption signals daily, but also volcanic tremor.

Merapi: Second lava dome grows

VSI volcanologists report that during recent fieldwork at the summit of Merapis, they discovered a second lava dome in the crater of Merapis. It is growing in the central area of the crater and is only slightly offset to the south. Due to cloud cover, the researchers were unable to determine the volume of the new dome. It is still supposed to be quite small. But in the future pyroclastic flows could flow in a direction that has been spared from them until now. Until now, it was mainly places in the southwest of the volcano that were threatened. Hanik, the head of the local disaster protection, explained that now not only Kali Boyong, Krasak, Putih, Bedog and Bebeng are threatened, but also the region around Kali Gendol.

At last, new data on the dome so far have also been published: its volume is 117,000 cubic meters, with a daily growth rate of 13,000 cubic meters. Pyroclastic flows and debris avalanches have recently been greater than the growth rate, so the dome has lost more volume than it has gained. In fact, the data are similar to those last communicated 2 years ago.

Etna: Bocca Nuova fills up

A new video documenting the activity of Bocca Nuova has been shared in our Facebook group. It was taken from the crater rim and shows that strombolian activity from this crater is more intense than one might expect from below. A cone is forming above the western vent and hornitos are growing above two other vents further east. Tephra fills a good part of the crater, overlying lava flows from last winter. MIROVA records high thermal radiation with a power of 214 MW. The high thermal radiation is caused either by a lot of incandescent tephra, or by a small lava flow. In addition, a magnitude 2.5 earthquake occurred today, with the hypocenter located at a depth of 3.9 km. The epicenter was located 1.4 km northwest of Monte Centenari. This cinder cone is located in the Valle del Bove. Since yesterday, the INGV registered 10 earth tremors. Unusually many quakes had magnitudes from 2.0.
