Thanks LGD - people are so unaware of what could happen in an instant, that will change the face of nations and millions of lives. Blessings - RON :tiphat: 

I'm reminded of this verse 

 

Proverbs 29:1 – “He who is often rebuked, and hardens his neck, will suddenly be destroyed and that without remedy.”

Indonesia earthquake: Buildings rocked by 6.7 magnitude tremor near Jakarta

By  Dave BurkeSenior News Reporter   10:07, 14 Jan 2022      UPDATED12:02, 14 Jan 2022

Indonesia's meteorology agency (BMGK) said the earthquake hit 32 miles off Banten province at a depth of 10 km, but did not have the potential to cause a tsunami.

A magnitude 6.7 earthquake has rocked Indonesia, with terrified people forced to flee buildings as the ground rocked.

Tremors were felt at least 100 miles way, witnesses have said, while buildings were damaged in Pandeglang in Banten.

Families were forced to evacuate their homes as the quake unfolded this morning.

Indonesia's meteorology agency (BMGK) said the earthquake hit 32 miles off Banten province at a depth of 10 km, but did not have the potential to cause a tsunami.

In Jakarta, the tremors were felt strongly. Jakarta resident and nanny, Ani, 38, said: "I was very scared, suddenly there was a quake and it was so strong.

"When I felt it I directly grabbed my employer's baby and ran downstairs."

Another resident, Ade, 34, was on the 15th floor of a Banten apartment.

"I was in a Zoom meeting when people all shouted 'Earthquake!'," said Ade, who declined to give her second name.

"The tremors were so strong and I was in shock, I couldn't immediately get downstairs, I needed to steady my body."

The quake was also felt in the provinces of West Java and Lampung, on Sumatra island.

The agency said it had received initial reports of damage in Pandeglang in Banten.

Speaking to Kompas TV, Banten governor Wahidin Halim said four homes had been damaged, one Islamic school had collapsed, and cracks appeared at a mosque.

The quake was also felt in the province of West Java and in Lampung, on Sumatra island.

Indonesia straddles the so-called "Pacific Ring of Fire", a highly seismically active zone, where different plates on the earth's crust meet and create a large number of earthquakes and volcanoes.

Last month, a 7.4-magnitude earthquake struck eastern Indonesia, triggering a tsunami warning and also sending
residents fleeing from their homes.

The quake only caused minor damage and injured one person, authorities later said.

Watch out for Sunda Strait's megathrust segment: BMKG

 15th January 2022

Watch out for Sunda Strait's megathrust segment: BMKG

Watch out for Sunda Strait's megathrust segment: BMKGIllustration - A 20-meter-high tsunami might occur if two megathrust segments collide.

 

"  The earthquake in Ujung Kulon, Banten, yesterday, was actually not a real threat because the megathrust segment of the Sunda Strait is capable of triggering an earthquake, with a targeted magnitude of 8.7, and this can occur at any time. This is the  "

 

Jakarta (ANTARA) - Sunda Strait's megathrust segment is one of Indonesia's seismic gap zones, with no earthquakes for centuries, so it should be watched out for, Meteorology, Climatology, and Geophysics Agency's (BMKG's) earthquake, tsunami mitigation coordinator Daryono stated.

"The earthquake in Ujung Kulon, Banten, yesterday, was actually not a real threat because the megathrust segment of the Sunda Strait is capable of triggering an earthquake, with a targeted magnitude of 8.7, and this can occur at any time. This is the real threat," Daryono stated on Saturday.

The coordinator noted that no technology had yet been able to forecast when an earthquake will occur, especially with the condition of hundreds of years of no reported earthquake. Moreover, Sunda Strait is located between the locations of two major earthquakes: the 2006 Pangandaran earthquake of M7.7 and the 2007 Bengkulu earthquake of M8.5.

Based on historical records of earthquakes and tsunamis, it was found that tsunamis are frequent in the Sunda Strait region. The Sunda Strait tsunamis that occurred in 1722, 1852, and 1958 were caused by earthquakes.

Moreover, the tsunamis in 416, 1883, 1928, and 2018 were related to the eruption of Mount Krakatoa, whereas the tsunamis of 1851, 1883, and 1889 were triggered by avalanche activity.

Daryono noted that strong earthquakes and tsunamis were natural processes that cannot be stopped. The BMKG cannot forecast when they would occur.

"However, amid the uncertainty, we can still undertake concrete mitigation efforts, such as by construction earthquake-resistant buildings and modeling the dangers of earthquake and tsunamis, and then using this model as a mitigation reference," he remarked.

The coordinator called on the local government to conduct regional planning based on the earthquake and tsunami risk, ready evacuation routes, install evacuation signs, build evacuation sites, and practice evacuation and drills on a regular basis, including edifying on self-evacuation.

In addition, the BMKG will continue to improve the performance of tsunami forecasting and early warning system to make it faster and more accurate, he added.

BMKG: Sunda Strait Megathrust Tsunami Could Reach Jakarta In 3 Hours

Tsunamis in the Sunda Strait could be triggered by volcanic eruptions and tectonic earthquakes sourced in the megathrust zone, according to daryono, head of the earthquake and tsunami mitigation agency of the Climatology and Geophysics Meteorology Agency (BMKG).

Based on historical records, the tsunami caused by the eruption of Mount Krakatau in 1883 was able to reach Jakarta Beach because the height of the tsunami at its source was more than 30 meters, while the tsunami in 2018 was much smaller, so it did not reach Jakarta.

“To find out whether the tsunami caused by the Sunda Strait megathrust earthquake can reach Jakarta, tsunami modeling is needed. Modeling of the Sunda Strait tsunami due to the magnitude 8.7 earthquake conducted by BMKG shows that the tsunami can reach Jakarta Beach,” he said, as quoted from Instagram @daryonobmkg, Monday, August 23, 2021.

The modeling results showed that the tsunami reached Jakarta Beach within about 3 hours after the earthquake with a height of 0.5 meters in Kapuk Muara-Kamal Muara and 0.6 meters in Ancol-Tanjung Priok.

Tsunami modeling is measured from the average sea level (mean sea level). In the worst cases, if a tsunami occurs at high tide, then the height of the tsunami can increase. In addition, the height of the tsunami can also increase if the coast of Jakarta has experienced a decrease in surface (subsiden).

Tsunami modeling has very high uncertainty. This is due to the very sensitive modeling equations with the data and earthquake generating sources used.

“Different data used, then the results will be different. Even if the source of the tsunami is shifted slightly, then the results will also be different. This is why there is always a difference in results between tsunami model makers,” daryono said.
