Indonesia is investigating today with foreign scientists how the tsunami of a week ago in the Strait of Sonda, originally attributed to the collapse of the Anak Krakatau volcano, whose crater has lost about 200 meters high.
Australia, the United States, France and Japan are the countries with which Indonesia shares geological data, according to Indonesian Minister of Energy and Mineral Resources, Ignasius Jonan.
The objective is to learn from the experience and improve the accuracy of the analyzes because the tsunami on the 22nd in the Sonda Strait, which separates the islands of Java and Sumatra, was the first recorded in Indonesia that does not originate in an earthquake.
The Indonesian authorities have not offered an official explanation of the cause to date, although one of the most recurrent hypotheses is that the collapse of a section of the volcano produced the tsunami.
The Anak Krakatau, Indonesian name that means "son of the Krakatoa", was raised in an island of the Strait of Sonda to 340 meters on the level of the sea, but after the happened thing its height has been reduced to 110 meters.
The fall of that section in the sea could be the origin of the waves of several meters that fell on the coasts of southern Sumatra and western Java on the night of Saturday, December 22.
Some Indonesians were surprised by the catastrophe lying down, others at home in front of the television or at the table or outside the house.
When the waves arrived, Wahid was making meatballs, which he then sells, at his home in the village of Way Muli, in the province of Lampung, in Sumatra.
He survived, but his house suffered significant damage, like all those buildings built of wood and palm instead of bricks and cement.
The latest official data of victims confirm 426 dead, 23 missing, 7,202 injured and 40,386 displaced.
The district of Pandeglang, in the province of Banten, in Java, is the most affected area, with 288 fatalities.
"The displaced people still need daily and logistical assistance," the spokesperson for the National Agency for Disaster Management (BNPB), Sutopo Purwo Nugroho, admitted on social networks today.
The Red Cross and Doctors without Borders are some of the national and foreign organizations that provide assistance to evacuees.
Many of the displaced people wait for the authorities to allow them to return to their homes, others have decided for themselves that they will receive 2019 in their homes or relatives' homes.
The authorities still do not give the green light because the Anak Krakatau has not calmed down, indeed, last Thursday they had to raise the alert level from two to three, on a scale of four.
The measure meant the imposition of a zone of restricted access around the five-kilometer volcano and the petition to the inhabitants on both sides of the Sonda Strait to maintain a distance of between half a kilometer from the sea, in another tsunami
The president of the Indonesian Council of Ulemas, Ma'ruf Amin, said today at a religious ceremony in Banten for the victims that the tsunami was not a divine punishment.
Amin, who competes for the country's vice presidency in the April 17 elections, added that it could nevertheless be a test to prove the faith of the Indonesians.
Indonesia is the fourth most populous country in the world with 265 million inhabitants and the one with the largest Muslim community.
The Sonda is the second major tsunami suffered by the Indonesians this year, after the one that occurred on September 28 on the island of Celebes that killed 2,256 people.
The worst tsunami recorded in Indonesia happened on December 26, 2004 and caused 167,000 deaths in the country, in addition to another 59,000 in eleven countries bathed by the Indian Ocean, such as Thailand, India or Sri Lanka.
