Intense eruption continues at Krakatau, alert level remains at 2 of 4, Indonesia

Blog note: And great earthquakes shall be in diverse places, and famines, and pestilences; and fearful sights and great signs shall there be from heaven. (Luke 21:11). Jesus is giving a series of prophecies about what to look for as the age of grace comes to a close. This verse from Luke is one of many such prophecies from throughout the Bible. 2017 was the worst year in recorded history for the intensity, frequency, severity, duration and occurrence of a large number of severe natural disasters worldwide. Earthquakes, volcanoes, hurricanes, typhoons, cyclones, torrential flooding, unprecedented wildfires in unusual places, devastating droughts, excessive/scorching heat setting records everywhere, record snowfalls in Europe and Russia. Snow in the Arabia. This list can go on. Most studied eschatologists believe these ‘fearful sights’ and massive natural disasters are all part of the ‘CONVERGENCE’ of signs that this Biblical and prophetic age is closing. Most people who study prophecy are familiar with the routine reference(s) made that these things will be like a woman having labor pains that occur in greater severity, frequency, size and duration prior to giving birth. End of note.

Intense eruption continues at Krakatau, alert level remains at 2 of 4, Indonesia

Mount Anak Krakatau erupted 56 times on Saturday, September 22, 2018, the Meteorology, Climatology, and Geophysics Agency (BMKG) reported September 23. The alert level remains at Level II (Waspada/Caution).

Thick black smoke produced by the eruptions rose up to 200 – 300 m (650 – 1000 feet), the Mount Anak Krakatau monitoring post said.

The last VONA was issued at 22:56 UTC, September 21. It was related to an eruption at 22:48 UTC, recorded with a seismogram with a maximum amplitude of 45 mm. The eruption lasted about 115 seconds, producing ash column that rose up to 538 m (1 722 feet) above sea level, drifting south.

Based on satellite data, the Darwin VAAC reported that during September 11 – 13 and 17 – 18, ash plumes from Anak Krakatau rose to altitudes of 1. 5- 1.8 km (5 000 – 6 000 feet) above sea level and drifted NW, W, and SW. Ash plumes on September 8 rose to altitudes of 4.9 – 5.5 km (16 000 – 18 000 feet) a.s.l.

Geological summary

The renowned volcano Krakatau (frequently misstated as Krakatoa) lies in the Sunda Strait between Java and Sumatra. The collapse of the ancestral Krakatau edifice, perhaps in 416 CE, formed a 7-km-wide (4.3 miles) caldera.

Remnants of this ancestral volcano are preserved in Verlaten and Lang Islands; subsequently Rakata, Danan and Perbuwatan volcanoes were formed, coalescing to create the pre-1883 Krakatau Island. Caldera collapse during the catastrophic 1883 eruption destroyed Danan and Perbuwatan volcanoes, and left only a remnant of Rakata volcano.

This eruption, the 2nd largest in Indonesia during historical time, caused more than 36 000 fatalities, most as a result of devastating tsunamis that swept the adjacent coastlines of Sumatra and Java. Pyroclastic surges traveled 40 km (25 miles) across the Sunda Strait and reached the Sumatra coast.

After a quiescence of less than a half century, the post-collapse cone of Anak Krakatau (Child of Krakatau) was constructed within the 1883 caldera at a point between the former cones of Danan and Perbuwatan. Anak Krakatau has been the site of frequent eruptions since 1927. (GVP)
