Tsunami Bali





This summer I’m back in Indonesia with the In Harm’s Way team of faculty and students from BYU, UVU and UPN (Universitas Pembangunan Nasional). Funding for our project comes from Geophysicists without Borders. This year part of our team is surveying, trenching, augering and drone flying along the coasts of Bali, Lombok and Sumba to find evidence of past tsunamis and to measure past levels of inundation. We are also conducting interventions in schools where we survey students about tsunami awareness and teach about preparedness. My main contribution is to analyze evacuation procedures and routes and when possible to hold tsunami evacuation drills. 

Our first stop was the Island of Bali where we worked in the area from Denpasar southward. This is a densely populated areas, with a heavy tourist concentration. It is also very vulnerable—flat and threatened by tsunamis from both the southwest and southeast. We joined the group a few days late after the end of the English Summer Camp in Solo. 

Saturday morning (July 15), Joel, Isaac and I joined part of our team for two school presentations.


The first school was an elementary school on the narrow Tanjung Benoa peninsula 


 

While I interviewed school officials about evacuation procedures, the rest of the team taught tsunami principles to the children in part by playing a large tsunami game based on the childhood game of Chutes and Ladders.


 



In the event of an earthquake and possible tsunami, the children of the school are to head down the street to two large hotels--Novotel and Ion-- which have upper stories that are safe.

These buildings of the Novotel are the evacuation gathering point.

Other hotels along the narrow peninsula also serve as evacuation places.


While at the Novotel, I asked if there was any effort to ensure the safety of tourists. I was told that the parent company of the hotel requires that all rooms have placards by the doors (above) and brochures explaining what to do in the vent of an emergency. I was hoping to hear that a requirement to provide such information was a provincial or national policy, but not yet.



The second gathering point for the school children. The upper stories of hotels are probably the best and safest place for tourists to go in southern Bali.


Our second stop was at the Kuta Pura High School.

Which is sure to be hit in the event of a tsunami. This school had no evacuation plan and no designated evacuation place. When asked, one student wisely said she would go to a nearby shopping mall with upper stories.



Later that day Joel, Isaac and I enjoyed Kuta Beach. I jumped waves and the boys boogie boarded. We also joined with hundreds of other tourists (where will they all go in the event of a tsunami) in releasing newly hatched sea turtles.





Next morning (the boys flew out at 1:00 am) part of our group headed to Nusa Pineda and Lembongan Islands for some fantastic snorkeling. Our fist stop was Manta bay, but no manta rayys were to be found. We the snorkeled at Custal Bay, Gamat Bay (loved the variety of corals--with many in various shades of green) and then the drift dive along the Toyapakeh Wall which was everyone's favorite given the plentiful and wide variety of fishes. Years ago I did a very swift moving drift dive in this same area.

After lunch we explored the mangroves of Lembongan Island.




Monday morning we presented at SMP 2 (Junior High) in Denspasar.


Most of the students used their hand phones to take our survey via an Instagram link to a qualtrics survey.

We learned that this school's designated evacuation place is a large evacuation structure built by the government. It is about a kilometer walk to the building. Practice drills to the evacuation tower are held once each year.

The open lower floors let the tsunami waters pass unimpeded. Allowing merchants to use the ground floor for shops helps cut down of vandalism and gives the building a secondary use.

 Next stop was High School 6 in Denpasar. 


We met with a large goup of students in the third floor of the central building.

The evacuation plan for this school was to gather at a "lapangan kecil" (small field) near the golf course (putting all of the students right In Harm's Way). From there some unknown person or agency will give further instructions. A better plan wold be to gather in the big upper room and hope it is not a mega tsunami.

Petitioning gods would also be helpful.

A funeral procession with a marching gamelan orchestra further slowed traffic.


Later that afternoon three of use journeyed to the far west side of the Bukit (Hill) Peninsula to the cliff top shrine of Uluwatu. We handed out surveys as we could at a kecak dance to as many foreign tourists as were willing to help us out. Some were hesitant to pick one up as they neared the ticket gate, but later while in their seats with nothing else to do more decided to fill our the questionnaire. We are wanting to know how informed they are about tsunami causes and safety. We are hoping our study will provide useful data to encourage the tourism industry to make a great effort to inform tourists about tsunami dangers.







We all stayed at the budget Oasis Hotel, It has not tsunami information eaither in the room or at the front dest during check in. To get to the hotel cars and pedestrians need to navigate this narrow breezwawy.

Aik Arif , who is as reporter for the highly respected Kompas newspaper joined us in Bali and wrote several articles like the one above about our research and our teaching. On to Lombok.
