Mauna Loa volcano Alert Level and Aviation Color Code raised, Hawaii

Blog note. Jesus indicated that ‘fearful sights’ (various natural disasters) would occur leading up to the time known as the Tribulation and Great Tribulation (a combined seven year period of great destruction on earth). Although these types of things have occurred in the past for centuries and thousands of years, they could be identified as the ‘season of the times’ due to the ferociousness of these events. They would be occurring in greater intensity, severity, frequency, size, duration, scope … just like the pains that a woman experiences in labor the farther along she is in the labor process. We are in the ‘season of the times’ that comes just before the seven (7) year Tribulation/Great Tribulation period
… 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).
… And there shall be signs in the sun, and in the moon, and in the stars; and upon the earth distress of nations, with perplexity; the sea and the waves roaring; (Luke 21:25)
… Men’s hearts failing them for fear, and for looking after those things which are coming on the earth: for the powers of heaven shall be shaken; (Luke 21:26)
… This know also, that in the last days perilous times shall come. (2 Timothy 3:1)
Jesus is giving a series of prophecies about what to look for as the age of grace comes to a close. These verses are several 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, growing in intensity, frequency, size and duration.

Mauna Loa volcano Alert Level and Aviation Color Code raised, Hawaii

Earthquake and ground deformation rates at Mauna Loa Volcano have exceeded long term background levels over the past several months, forcing the Hawaiian Volcano Observatory to raise the Alert Level to Advisory and the Aviation Color Code to Yellow. All communities on the flanks of the volcano should be prepared for a possible eruption.

An eruption is not imminent and current rates are not cause for alarm, HVO said. However, they do indicate changes in the shallow magma storage system at Mauna Loa.

Following a significant earthquake swarm in October 2018, HVO seismic stations have recorded an average of at least 50 shallow, small-magnitude earthquakes per week beneath Mauna Loa’s summit, upper Southwest Rift Zone, and upper west flank. This compares to a rate of fewer than 20 per week in the first half of 2018.

Shallow earthquakes are occurring in locations similar to those that preceded Mauna Loa’s most recent eruptions in 1975 and 1984. 

During this same time period, GPS instrumentation and satellite radar have measured ground deformation consistent with renewed recharge of the volcano’s shallow magma storage system. The current rate and pattern of ground deformation is similar to that measured during inflation of Mauna Loa in 2005 and again from 2014 – 2018. 

Together, these observations indicate the volcano is no longer at a background level of activity. Accordingly, HVO is elevating the Mauna Loa alert level to ADVISORY and the aviation color code to YELLOW.

This increase in alert level does not mean that an eruption is imminent nor that progression to an eruption is certain, the observatory said. A similar increase in activity occurred between 2014 and 2018 and no eruption occurred. 

As has happened before, it is possible that current low-level unrest will continue and vary in intensity for many months, or even years without an eruption. It is also possible that the current unrest is an early precursor to an eventual eruption.

“At this time, we cannot determine which of these possibilities is more likely,” HVO said.

HVO expects that days or weeks prior to an eruption, monitoring instruments will detect signs of an increased potential for eruption.

These signs could include further increases in rates of earthquakes and ground deformation, increases in the sizes of earthquakes, an increase in surface temperatures, or an increase in visible steam plumes or sulfur dioxide emissions.

“However, it is also possible that the timeframe to eruption could be shorter – hours to days. All communities on the flanks of the volcano should be prepared.”

Mauna Loa is the largest active volcano on Earth. Eruptions typically start at the summit and, within minutes to months of eruption onset, about half of the eruptions migrate into either the Northeast or Southwest Rift Zones. Since 1843, the volcano has erupted 33 times with intervals between eruptions ranging from months to decades. Mauna Loa last erupted 35 years ago, in 1984.

Eruptions at Mauna Loa tend to produce voluminous, fast-moving lava flows that can impact communities on the east and west sides of the Island of Hawaiʻi. Since the mid-19th century, the city of Hilo in east Hawaiʻi has been threatened by seven Mauna Loa lava flows. Mauna Loa lava flows have reached the south and west coasts of the island eight times: 1859, 1868, 1887, 1926, 1919, and three times in 1950.

From 2014 through much of 2017, HVO seismic stations recorded variable, but overall elevated rates of shallow, small-magnitude earthquakes beneath Mauna Loa’s summit, upper Southwest Rift Zone, and west flank. During that same time period, HVO measured ground deformation consistent with input of magma into the volcano’s shallow magma storage system.
